 The effective dates section was a bit more complicated than in recent years, combining a first application issue with many 54(3) documents (2 in part one, 3 in part two). Complicating the date analysis was a request of the client to ensure fall back positions of claim 1 are attacked. Since claim 1 has two problems: a partial priority loss due to the first application issue, and added matter, candidates had to decide what the appropriate fallback should be.

We had some discussion on whether A5.4 (this notation also being used elsewhere and referring to A5 [4]) enables a novelty attack on claim 5. As the signal of the pressure sensors decides on the charging, it seems that all features are disclosed. A processing unit would be implicit as any unit that processes a signal may be called a processing unit. Nevertheless, this is attack seems too much of a stretch and was probably not the intention.

Claim 7 is another claim that we had some discussion about. The reference to pricing suggests that maybe an attack exploiting non-technicality might be possible. To follow this idea, one might take model Q as the closest prior art, and argue that it is already adapted to charge based on a signal. One would then argue that using a signal to represent pricing is a non-technical difference which may be ignored.

Unfortunately, this attack is not possible, since the model Q is not suited for wireless charging which is required by claim 7. The comments under A6 make clear that the model Q cannot be adapted to wireless charging either. This makes any line of attack against claim 7 starting from model Q impossible.

A second reservation we have about this argument, is that it is not altogether clear whether reference to price automatically makes a feature non-technical. Engineers are often charged with problems related to price, e.g., to make a device cheaper, and the solutions they find are typically technical. Also in this case, high energy price reflects a busy electrical network, so the feature of claim 7 contributes to reducing congestion on the electrical network.

The alternative option is to take model P as the closest prior art and focus on the RFC standard. This has the advantage that price related charging is actually disclosed, mooting a discussion about its technicality. This line of attack would require one to argue that it is implicit from A6 that model P is adapted to the RFC standard. We are not sure that A6 really clears this bar. Although model Q was the first model to have the standard, it might also have been the last—in other words, it is not inevitable that model P has the RFC standard. An alternative would be to accept that the standard is a distinguishing feature and introduce the standard via inventive step. This approach is also a bit dodgy since the obvious D2 document A7, is 54(3). The combining document would have to be the model Q. On balance we took the first approach, arguing that it is implicit that the model P has support for the standard.

Finally, we give our regards to Ms. Molly Dorsett Pauley. She must have quite a reputation as an opposition specialist after her successful oppositions in 2015 and 2021. 

We look forward to your comments!

PART 1

 

Opposition is filed against EP patent EP 3 831 740 B1
Opposition fee is paid through online fee payment
All claims are opposed
Grounds include inventive step, novelty, added matter, see further the arguments
Representative: Ms. Pauley, Todiet Kwiscus LLC

Claim 1. Added subject matter.

Claim 1 was amended after filing by adding the feature : the magnetic material comprising amorphous CoFeNi at 10 - 30% and nanocrystalline FeCuSiB at 20 - 40% by weight of the magnetic material.

This feature was disclosed in the priority documents, but support must come from the application as filed, A.123(2).

The application as filed discloses in A1.12-13 the combination of a range of FeCuSiB at 30 - 40% and CoFeNi at 10%-20%. This does not support the amendment to claim 1. This combination of ranges protects against corrosion and provides mechanical stability. They are functionally related and these two ranges cannot be separated.

The application as filed discloses in A1.14 an alternate combination of a range of FeCuSiB at 20 - 30% and CoFeNi at 20%-30%. Claim 2 as filed discloses the same ranges. This does not support the amendment to claim 1. This combination of ranges provides mechanical stability. They are functionally related and these two ranges cannot be separated.

These two alternate embodiments cannot be combined. Accordingly, claim 1 has added subject matter.

 

Claim 1 may be regarded as a generic or-claim having three parts: 1) the range of A1.12-13, 2) the range of claim 2, 3) the range of claim 1 minus ranges 1) and 2). We need not concern us with the third part as it is added matter.

We will refer to part 1) as claim 1f, that is claim 1 limited to the ranges FeCuSiB 30 - 40% and CoFeNi 10%-20%.

Claim 1f is supported by the application as filed A1.12-13.

Since claim 1f is a subset of claim 1, any attack on claim 1f implies an attack on claim 1 as well.


Effective dates
Claim 1 was amended during prosecution, this amendment is added matter, see the attack above. No date will be assigned.

Claim 1f, this part of claim 1 is supported by text included in the earliest priority document, and gets the earliest priority date (25.05.2020).

Claim 2
First application issue

A1 claims priority from patent applications NO20200113 and NO20200355, but patent application EP19732000.1, A6’s priority document is the first application for art. 87(1), because:

-             A6’s priority document must have the same applicant as A6, i.e., Mute&Mercer Corp. This is the same A1’s applicant.

-             The filing date of EP19732000.1 lies before the filing date of A1’s earliest priority,

-             Y discloses the subject matter of claim 2 (see novelty attack below)

-             The possible exception of Art. 87(4) does not apply since it was used as priority document for A2.

Since A1 does not claim priority from EP19732000, but should have, Claim 2 is not entitled to priority and gets the filing date, Art. 87(1) and (4).

Claim 1f is not disclosed in A2, so no first application issue arises for this part of Claim 1.

Claim 3

Claim 3 is not disclosed in the priority documents. Supporting paragraphs a1.15 and a1.17 were also not part of the priority document. So Claim 3 gets the filing date.


Conclusion on effective dates:
Claim 1:no date since added matter
Claim 1f: 14.03.2020
Claim 2: 25.07.2020 since full priority loss
Claim 3: 25.07.2020


List of evidence
A2’s priority (EP19732000.1) is published on 23.07.2020. This is before filing date so 54(2) for claims 2,3

A2 is a EP patent application, filed before the earliest priority, and published after so, 54(3) for claims with valid priority: 54(3) for claim 1f

It is noted that A2 is 54(3) for all claims, but as we already have 54(2) prior art with the same document, this makes no difference.

A3 published before earliest priority so 54(2) for all claims

A4 published on 22.07.2020 before the effective date of claim 2,3: 54(2) for claim 2,3


A4 is EP and filed before earlies priority (3.01.2020), published after so 54(3) for claims 1f

Annex 5 (A5) is an Advertising brochure. It was Distributed with Lawn & Order, Journal for Xtreme Gardening, vol. 01/2020, 13 Dec. 2019
Accordingly it was public at least by 13.12.2019 before earliest priority of a1. so 54(2) for all claims.

Summary

A2 : 54(3) for claim 1f

A2: 54(2) for claims 2,3

A3: 54(2) for claim 1f, 2, 3

A4: 54(3) for claim 1f
A4: 54(2) for claim 2,3

A5: 54(2) for claims 1f, 2, 3

Note A2 the 54(3) and A2 the 54(2) are technically not the same document, although they have identical content.


There are no attacks under art. 54(3)

Attacks under art. 54(2)


Claim 1f
(FeCuSiB 30 - 40% AND CoFeNi 10%-20%)

Available documents: A3, A5

Inventive step: A3+A5.

A3 is the CPA because it is from the field of Charging pads suitable for charging a car (A3 title). This is the same purpose of the claim (claim 1 preamble, A1 title). Moreover, A3 discloses two coils side by side in a similar arrangement as claim 1.


A3 anticipates the features of Claim 1 as follows:

Charging pad:

A3 para 4: “charging pad”
a first coil (131) and a second coil (132), A3.9: "a first solenoid with its windings is created and next to it a second solenoid with its windings. This is a double-O solenoid."
we know from A4 [3], cited as evidence, that "A solenoid consists of a conductive trace with several concentric windings." This matches the definition of a coil in A1.5, a coil is "is a conductive trace with several concentric windings". So A3 discloses a first coil and a second coil.

both for resonant wireless charging,

A3.9: “the shape of the wire path is chosen such that the two solenoids are tuned to the intended charging frequency.” Following A1.6, if a coil has "a layout such that it is tuned to the charging frequency" then it is " coil for resonant wireless charging", so this part is disclosed in A3.
the first coil and the second coil being arranged side by side,

The two solenoid of A3 as "next to" each other, A3.9

a first layer (135) made of a magnetic material,
A3.7: "blank 332",

the blank is made of
A3.5: “the polymer is TP.190, a thermoplastic with a melting point of 190°C. It is combined with grains made from alloys such as CoFeNi, FeCuSiB or NbSiBCo. Such alloys are magnetic”

Blank 322 is a layer, see A3 fig. 2, and it is made of magnetic material.


wherein the first coil and the second coil have been placed on a first surface of the first
layer and the first layer has been treated so that the first coil and the second coil have
sunk into the first layer,
This is a product by process claim (see Guidelines F-IV, 4.12). It is sufficient to find a method that will give the same result as the claimed process steps.
A3.8: “A wire feeder 334 behind the heater head lays the conductive wire 335 into the
liquified area. (...) In this manner a first solenoid with its windings is created and next to it a second solenoid with its windings.”
So, the first coil and the second coil have been placed on a first surface of the first
layer. Blank 322 is heated ("heater head 333 which locally heats the blank to a
temperature above the melting point of the polymer to create a liquified area 336.") so it is treated. The coils sink into the layer since: “As the robot arm moves forward, the polymer re-solidifies over the wire.”
Thus a product is obtained by a process that falls under the scope of the claim.


the magnetic material comprising amorphous CoFeNi

A3.5: It is combined with grains made from alloys such as CoFeNi, FeCuSiB or NbSiBCo.
which is "amorphous", according to A3.6
A3 discloses amorphous CoFeNi

and nanocrystalline FeCuSiB at 30 - 40% by weight of the magnetic material. ( Note the restricted ranges)

A3 also discloses nanocrystalline FeCuSiB
Although in A3.5-6, amorphous FeCuSiB used, A3.11 explains to treat amorphous FeCuSiB to so that they “contain crystal cells measuring between 150 nanometers and 300 nanometers.”

According to A2.5, cited as evidence “Nanocrystalline alloys … are characterised by having crystal cells smaller than 1 micrometre.” Since 300 nanometers is below 1 micrometre, the FeCuSiB of A2 is nanocrystalline.

A3.11 discloses to use nanocrystalline FeCuSiB in a range of 32 to 38% by weight of the blank. Both endpoints anticipate the range 30 - 40%.

Accordingly the distinguishing feature the range of CoFeNi: the magnetic material comprising amorphous CoFeNi at 10 - 20%

Effects:
A1.13: “For such a composite the use of at least 10% amorphous CoFeNi by weight of the
material has the surprising effect of preventing oxidation of FeCuSiB.”
Accordingly, prevention of oxidation is obtained.

The OTP is: how to prevent of oxidation in a charging pad. This problem is recognized in the CPA, A3.10


The skilled person would read A5 as it relates to the problem of charging mobile equipment (A5.2), in this case a robot mower. The technology of A5 is relevant to cars since it is licensed therefrom.

A5 recites:
A5.3: “a protective magnetic material consisting of TP.190 at 52% by weight and nanocrystalline FeCuSiB and amorphous CoFeNi at a ratio of 2:1.”
So the non TP.190 part is 48%. So FeCuSiB part is 48*2/3 = 32 % and CoFeNi part is at 48* 1/3 = 16%

These points anticipate the claimed range.

The skilled person has an incentive to apply this teaching since A5 discloses that protection against corrosion is obtained A5.2, A5.4. Note that corrosion and oxidation are the same A1[12].

The skilled person would take the charging pad of A3 but change the amounts of nanocrystalline FeCuSiB and amorphous CoFeNi to a ratio of ratio of 2:1 of 48%. That is 32% and 16%.

Not that both A3 and A5 use the same polymer TP.190; both A3 and A5 use the same amount of nanocrystalline FeCuSiB (32%). So adapting to the ratio of A5 is expected to work in A3.


Claim 2
Annex 2's priority doc (EP19732000.1) published on 23.07.2020 is 54(2) for this claim. It discloses claim 2 in A2.2-4. So claim 2 is not novel.

It is noted that claim 2 is also not novel using A2 as a 54(3) document.

Claim 3
Inventive step A2+A4. We refer to Annex 2's priority doc (EP19732000.1).

A2 is the closest prior art because it lies in the field of charging pads (A2 title), it may be used to charge cars (A2.1). Moreover, it discloses a magnetizable concrete ( see below).


A2 anticipates the following features of Claim 3
Charging pad comprising:
a first coil (131) and a second coil (132), both for resonant wireless charging,
the first coil and the second coil being arranged side by side, and
See paragraphs A2.2


A2 anticipates

a first layer (135) made of magnetisable concrete ;
since it recites
A2[6]: “In an aspect of the invention, the magnetic material has a density of at least
2000 kg/m³ and comprises cement and magnetic particles.”

According to A1[15]: “In an embodiment of the invention, the magnetic material is magnetizable concrete. This is magnetic material comprising cement and having a density of at least 2000 kg/m³.”

So A2.6 discloses in magnetisable concrete


A2 anticipates
the charging pad further comprising a second layer (136) arranged next to the first layer.
Since A2 recites
A2[7]: “The charging pad may comprise a second layer 136 next to the first layer.”


The distinguishing feature is that the: second layer (136) is made of an electrically conductive material.

For the effect of this feature:
A1.19: Within such a second layer neutralising currents, known as eddy currents, are created which locally cancel the unwanted radiation.


The OTP is: How to locally cancel the unwanted radiation in a charging pad.


This is needed for regulations A1.18. So the skilled person would in any case be motivated to solve this problem. This problem is recognized by A2.8.

The skilled person would read A4 because it relates to a solenoid with active shielding (i.e. coils), A4, title; A4 further refers to high power wireless charging pads, such as those needed for charging cars; and to preventive measures against unwanted electromagnetic fields.

A4 recites

A4.7: For instance, it is well known that wireless charging pads benefit from having a metal sheet close to the solenoid as a layer of the charging pad. During operation, eddy currents are created within the metal sheet.

Metal is an example of an electrically conductive material, A1.19.
A metal sheet is an example of a second layer. So A4 discloses a second layer (136) made of an electrically conductive material. It is arranged next to the solenoids, which are part of a first layer.

The skilled person has an incentive since
A4.7-8: “ During operation, eddy currents are created within the metal sheet. The unwanted radiation is thereby locally neutralised.”

And so A4 is likely to solve the OTP.

The skilled person will take the configuration of A2, but make the second sheet out of metal.

The charging configuration using coils is similar to the CPA, so the skilled person will expect it to be compatible. Furthermore, A4.8, "Irrespective of the exact configuration of the solenoid or the materials in the charging pad", so the skilled person will expect this to work.

This novelty attack on claim 2, is also a novelty attack on the corresponding part of claim 1.

PART 2

Effective dates

First application issue: None of claims 4-7 are disclosed in A2. So no priority loss

Claims 4 and 5 are both recited in priority document N'355. Resonant sensing or signals are not disclosed in N’113, that is paras 1-13 nor its claims. So claims 4 and 5 get the N'355 date: 25.5.20.

Claim 6 is recited in the filing. Para 27 discloses that a signal from the detection unit is provided to the processing unit. But this para is not in the priority documents. So Claim 6 gets the filing date: 25.07.20

Claim 7 is recited in the filing. Para 33 discloses the use of price. But this para is not in the priority docs. So Claim 7 gets the filing date: 25.07.20

List of evidence

A3 and A5 are published before the earliest priority and are 54(2) against all claims.

A2 and A7 are EP patent applications, both filed before the earliest priority, and published after. These are 54(3) against all claims

A2’s priority document is published on 23.07.20 and is Art. 54(2) prior art for claims 6 and 7

A4 is published 22.07.20. Before the filing date so 54(2) for claims 6, 7

A4 is an EP patent applications, filed before the earliest priority, and published after the priorities. This is 54(3) against claims that have a priority date: 54(3) against claims 4, 5

A6 is transcription in Annex 6 of a podcast E-Mobility, on BBCee Radio9 with Walt Edge and Dan Shen. We also provide a Screenshot downloaded and printed 2024-03-14, 07:42:18. See A6 page 4. The screenshot proves that E-Mobility is a show presented by Walt Edge (@waltedge) and Dan Shen (@danshen) and broadcast by BBCee Radio9 in London, UK. The producer is Ann Pear.

The podcast was broadcast 30 May 2020, 16:00. See A6.1 and the screenshot.

A digital copy of the podcast can be downloaded from:

https://www.podcloud.com/BBC9/programmes/b07dx75g/20200430.ogg

A podcast is part of the state of the art under art. 54(2) epc since it was made available to the public by broadcasting.

Accordingly, the content of the podcast as described in the transcript is public from 30 May 2020. This makes it 54(2) for claims with the filing date, i.e., claims 6, 7

 

A6 also provides evidence of the sale of a Model Q, between 2015-2017, and an update in 2018. The sales were unconditional and the updates was received by owners of the model Q, so both are part of the state of the art. 2018 is before the earliest priority. So Model Q and the update are 54(2) for all claims.

 

Summary:

A2: 54(3) claims 4, 5

A2’s priority document: 54(2) claims 6, 7

A3: 54(2) all claims

A4: 54(3) claim 4, 5

A4: 54(2) claims 6, 7

A6: 54(2) claims 6, 7

A6 (as evidence of model Q and update) : 54(2) all claims

A7: 54(3) all claims

 

Attacks under art. 54(3)

Claim 5 lacks novelty under 54(3) against A7.

A7 anticipates

Method for controlling a charging system to selectively charge a battery of an electric vehicle,

A7.6 : “charging terminal” for charging a car.

This is a charging system. The charging terminal is for charging the battery of a car. (A7.7 last line, it is implicit that the battery is part of the car). The charging terminal is an example of a charging system as it charges a battery.

A car is an example of a vehicle, A2.1. Since it has a battery, it is an electric vehicle.

The charging is selective, A7.9, shows charging can be triggered or not by the microprocessor of the terminal.

the method comprising the following steps executed by a processing unit included in the charging system:

A7.7: Such charging terminals contain a programmable microprocessor

A programmable microprocessor is an example of a processing unit, A1[32]. The charging terminals is a charging system.

- receiving a signal,

A7.8: “Most importantly, such charging terminals also have mobile data connectivity which enables them to continuously receive signals indicating the price of electricity.”

Signals indicating the price of electricity are an example of a signal

- deciding, based on the received signal, whether the battery should be charged or not,

A7.9: “If the price of electricity drops below a first value which can be set by the user, the microprocessor may trigger charging. If the price of electricity rises above a second value which can also be set by the user, the microprocessor may interrupt charging.”

The microprocessor decides based on the received signal to trigger charging, that is whether to charge or not.

- if it is decided that the battery should not be charged, causing an electrical connection outside the vehicle to be inactive.

A7.7: “They also contain power switches which enable or disable the electrical connection to the electricity grid. Any skilled person in the field knows that for safety reasons any cable plugged into the charging terminal should be kept free from electrical tension unless the battery is being charged.”

The terminal of A7 is also for plug-socket charging, A7.6. Thus the cable is kept free from electrical tension while plugged in, but not charged. Since an electrical connection to the grid is disabled when not charging, an electrical connection is caused to be inactive. This is a connection between charge cable and grid, which is outside the car.

Attacks under art. 54(2)

Claim 4

Documents: A3, A5, A6 as evidence of disclosures before (25.5.20)

Claim 4 is not novel 54(2) over document A5

A5 discloses

Charging system for charging a battery,

A5 discloses a robot mower called ORBIT, A5.1. The ORBIT has a "system for resonant wireless charging", A5.2. It is implicit from this and A5.13 that the ORBIT has a battery. Indeed, the charging happens in case of low battery charge. Thus, the ORBIT is an example of a charging system since it can charge a battery (its own battery).

the charging system comprising: a processing unit (152),

A5.7 and fig.2 disclose a microprocessor which is an example of a processing unit, A1.32.

a first coil (151) for resonant wireless charging, and

The ORBIT has a

A5.2: “a system for resonant wireless charging”

It comprises a coil, see

A5.7: “the coils in the charging pads”

A coil is furthermore implicit in wireless charging, A1.4. See also A4 [3]: known charging pads comprise a solenoid 411. So a solenoid is implicit in a charging pad, this is an example of a coil.

a detection circuit comprising a plurality of second coils (153a, 153b, 153c) for resonant sensing,

A5.5 recites a resonant sensing system (RSS), which has an excitation solenoid, A5.9, and a probing solenoid, A5.10.

A solenoid is an example of a coil.

See A4.3: A solenoid consists of a conductive trace with several concentric windings, which is a coil, A1.5.

Two coils are a plurality of coils.

said detection circuit being configured to:

- create a sensing field with a first of said second coils,

A4.9: “The RSS works by continuously sending an excitation current into an excitation solenoid tuned to 500 kHz to generate a nearby electromagnetic sensing field.”

Thus, the excitation solenoid is a first of said second coils. An electromagnetic sensing field is an example of a sensing field.

- probe said sensing field with a second of said second coils,

A5.10: “A probing solenoid is mounted in proximity to the excitation solenoid and is also tuned to 500 kHz. The probing solenoid continuously picks up the sensing field “

Thus, the probing solenoid is a second of said second coils. Picking up the sensing field is an example of probing the sensing field.

- obtain a signal representative of the sensing field, and

A5.10: “... creates a detection current which reacts to any changes in the sensing field.”

A detection current is an example of a signal. The detection current reacts to changes in the sensing field and thus represents it.

- provide said signal to the processing unit.

A5.7: “Downstream of the sensing system (see Fig. 2) the detection current (signal) is continuously measured by a sampling circuit and forwarded as a signal to a microprocessor (processing unit).”

Although A1's description intents to use the resonant sensing to detect interruptions to charging, and A4 to driving. Claim 4 is not limited to this. Accordingly. Claim 4 is not novel.

 

Claim 5

Lack of novelty over the 2018 update of the Model Q (evidence provided by A6):

The 2018 update of the Model Q anticipates:

Method for controlling a charging system to selectively charge a battery of an electric vehicle

see below

the method comprising the following steps executed by a processing unit included in the charging system:

A6.8: "That’s one of the many functions of model Q’s battery control system, which is software that runs on the onboard computer".

According to A1.32, the car's on-board computer is an example of a processing unit. The following steps are performed by the on-board computer and thus executed as a method by the on-board computer.

receiving a signal

A6.9: "Model Q has a heat sensor inside the battery which sends the temperature as a signal to the battery control system",

deciding, based on the received signal, whether the battery should be charged or not

A6.10: "The 2018 update enabled the battery control system to take over the decision-making. It checks if the temperature is in a range deemed acceptable for battery charging.")

if it is decided that the battery should not be charged, causing an electrical connection outside the vehicle to be inactive

A6 .11: "If it’s not, the battery control system decides that charging shouldn’t start or, if it’s already begun, that it should be stopped".

Claim 5 thus lacks novelty over the model Q in the 2018 update.

Claim 6

Lack of inventive step: A6 (model P) + A5

A6 describes the model P. This is the closest prior art because it is an electric vehicle for selective wireless charging, A6.2, A6.18

Claim 6 refers back to claim 5, and uses a charging system according to claim 4

A6 anticipates the following Claim 4 features

Charging system for charging a battery,

A6.2: “Model P will be their first electric car (…) it will also feature exciting advances for wirelessly charging the battery”

A6 [3]: "Model P has a car charging pad"

A charging pad is an example of a charging system

Thus the model P has a charging system to charge its battery

the charging system comprising:

a processing unit (152),

A6.18: The model P has an "on-board computer". This is an example of a processing unit, A1.32

a first coil (151) for resonant wireless charging, and

A6.3: “Model P has a car charging pad with a double-O solenoid.”

A solenoid is a coil. Furthermore,

A3.2 (cited as evidence): “Recently it has been proposed to replace the single solenoid of a charging pad with a double-O solenoid. Admittedly, such a structure has drawbacks: it can be used only for resonant wireless charging”

Since a double-O solenoid can only be used for resonant wireless charging, it is implicit that double-O solenoid of A6 is suitable for resonant wireless charging.

a detection circuit,

A6.15: “Model P is equipped with an infrared sensor which monitors the thermal signature in the charging area.”

The infrared sensor is a detection circuit, as it detects things, in particular cats, A6.14

- obtain a signal representative of the sensing field, and

- provide said signal to the processing unit.

A6.15: “The sensor’s output current is sampled at the input of the on-board computer, meaning that the strength of the thermal signature is available as a signal which can be processed”

sensor’s output current is an example of a signal. The field where the sensor operates is a sensing field. The sensor’s output current is sampled at the input of the on-board computer; thus it must be provided to it.

Features of Claim 5

Method for controlling a charging system to selectively charge a battery of an electric vehicle, the method comprising the following steps executed by a processing unit included in the charging system:

See above.

- receiving a signal,

The sensor’s output current is the signal, it is received at the onboard computer, which is a processing unit.

- deciding, based on the received signal, whether the battery should be charged or not,

A6.16: “The on-board computer detects any changes which are strong enough to mean that your cat might have moved into the charging area.”

Thus the received signal is processed

A6.18: “Model P’s on-board computer can have all the power switches change from on to off or vice versa: the power switches connecting the car charging pad to the battery and also the power switches within the charging terminal which feeds electrical energy into the ground charging pad. This means the electromagnetic charging field can be switched off entirely, giving complete protection from inadvertent field exposure. If the charging is switched off, the battery is not charged.”

So a decision is made based on the signal.

- if it is decided that the battery should not be charged, causing an electrical connection outside the vehicle to be inactive.

A6.18: “the power switches change from on to off or vice versa: (...) the power switches within the charging terminal which feeds electrical energy into the ground charging pad.”

the power switches within the charging terminal are outside of the vehicle (car). If they are switched off, they are inactive.

Features of Claim 6

Method according to claim 5, the charging system being the charging system according to claim 4, wherein the received signal is

- the signal provided to the processing unit by the detection circuit.

The signal used, is the signal from the infrared detection circuit.

 

A6 does not disclose:

a detection circuit comprising a plurality of second coils (153a, 153b, 153c) for resonant sensing,

said detection circuit being configured to:

- create a sensing field with a first of said second coils,

- probe said sensing field with a second of said second coils,

Instead, A6 uses an infrared sensor which monitors the thermal signature in the charging area, with its signal being provided to the on-board computer

The effect of these differences according to A1.24: detect whether a foreign object enters the charging area. In particular, an animal or a human body part, or a metal object such as a beer can, A1.28.

Judging from A6.19-20 The existing sensor may miss some situations. Thus the OTP is, how to improve detection whether a foreign object enters the charging area in a method for controlling a charging system.

Closest prior art A6 also recognizes that its thermal sensor is insufficiently reliable, e.g., not being able to detect a beer can rolling into the charging area, A6 [19], [20]

The skilled person would consult A5 since it relates to wireless resonant charging, A5.2, using technology from cars, A5.1. Moreover, the problem of detection is discussed in a5.5-12.

A5 discloses the missing features, see the novelty attack on claim 4 based on A5 above.

Furthermore, A5 teaches that a decision can be made based on the detection

A5.13: “Once an obstacle is detected the microprocessor instructs the robot to turn and go in a different direction.”

A skilled person would have an incentive.

A5.12: Resonant sensing has several advantages. Pets are reliably detected because a living body strongly distorts the sensing field. Resonant sensing also reliably detects metal objects, so it will protect your mower’s blades.

Thus the problem of A3, that some objects are not detected, e.g., a cat or a beer can, (a6.19, a6.14) is reduced. This happens because no reliance is on the ambient temperature.

The skilled person would thus replace the infrared detection of A6 with the Resonant detection A5.

This is possible because the system of A5 is modular, so the RSS can easily be taken out and incorporated elsewhere, A5.8.

Furthermore, there is no risk of impacting the charging.

A5.12: “The RSS operates at 500 kHz, while the coils in the charging pads have a layout so that they are tuned to the charging frequency of 85 kHz.”

This means there is no risk of harmful interference. According to A1.24 being tuned to different frequencies is enough for this.

The technology of A5 is "from automotive manufactures", see A5.1, which indicates that the resonant sensing system should work in an electric vehicle and thus in the Model P.

Finally,

A6.20: “Software updates are easier but OS-corp’s engineers often also propose hardware upgrades as long as they don’t require any changes to the car’s body”

So the Model P may easily update its hardware or software

 

Claim 7

Lack of inventive step over A6 'Model P' and A5,

Model P, as evidenced in A6, is the closest prior art since the onboard computer of the Model P, which is an electric vehicle, is capable of selectively charging the battery of the Model P.

For the disclosure of A6 in view of the method claim 5 and the system claim 4, see the attack on claim 6, also starting from model P.

A6 implies that the Model P is compatible with the standard RFC-7511-x.

A6.6: “So, OS-corp sold their model Q between 2015 and 2017. It was the first to be compatible with the then newly introduced standard RFC-7511-x.”

The model P is a later model of OS-corp, A6.2. Since, model Q was the first to be compatible with RFC-7511-x, this implies that the later model P is also compatible with RFC-7511-x

Indeed, the Model P has "the usual wireless data connection for software updates and receiving all kinds of data", see A6 [2].

Since model P is compatible with the standard RFC-7511-x, it is already adapted for price-dependent charging, and therefore has the additional functionality of claim 7.

The feature of claim 7 is disclosed in A7.6-10, in particular:

A7.8: “Most importantly, such charging terminals also have mobile data connectivity which enables them to continuously receive signals indicating the price of electricity. If the price of electricity drops below a first value which can be set by the user, the microprocessor may trigger charging. If the price of electricity rises above a second value which can also be set by the user, the microprocessor may interrupt charging.”

Since model P is compatible with the RFC-7511-x standard. Thus, the onboard computer of the Model P can selectively charge the battery based on the price of electricity when connected to a charging terminal also adhering to the RFC-7511-x standard.

The remaining distinguishing features are the same as for claim 6, we refer to the attack on claim 6 for a discussion of their obviousness in view of A5

    1. In addition to claim 7

      I think it's also possible to say the signal being a price signal does not contribute to the technical solution since the cognitive content of the signal only depends on the business interest of the user (evidenced in A7)

      Therefore, it can not be taken in to account when assessing inventive step but can only be used as constraints in the objective technical problem.

  2. Thanks for the solution.

    How does c4 work with A5 for novelty. I felt like A5 showed charger and a robot, that are obviously intended work together.

    But it are two different devices.

    Why would ghe skilled person replace the pressure pad with the RSS system?

    It's why I went over IS of a2 and A5. But admittedly, that IS also didn't have a strong incentive.

    Maybe I over thought it, but I spend too much time on C4 and the exam would have been a lot easier with a novelty attack.

    The first part went well, hopefully I scored enough in total for 50

  3. Is it just me or your claim 1f has added matter? A1§13 allows an amendment of 10 to less than 20% and not 10 to 20%. If the amendment is 10 to less than 20%, A2 and A2P1 will both be prior art for novelty and would destroy the novelty of claim 1 because A2 and A2P1 discloses a point value of 20%, which the skilled person would interpret as 19.5 to 20.4 (see Guidelines G-VI.7.1 and T 175/97).

  5. "Also in this case, high energy price reflects a busy electrical network, so the feature of claim 7 contributes to reducing congestion on the electrical network."

    I don't think that is necessarily true; high (and low) prices reflect an imbalance between demand and supply. High prices may thus well mean it is cloudy and not windy, leading to a shortage on the supply side, rather than to network congestion.


    "Claim 7 is another claim that we had some discussion about. The reference to pricing suggests that maybe an attack exploiting non-technicality might be possible. To follow this idea, one might take model Q as the closest prior art, and argue that it is already adapted to charge based on a signal. One would then argue that using a signal to represent pricing is a non-technical difference which may be ignored."

    Yes, this was basically my solution, with the observation that the resonant sensing system is not linked to the charging system/method, and that therefore a partial problem approach may be used.

    "Unfortunately, this attack is not possible, since the model Q is not suited for wireless charging which is required by claim 7. The comments under A6 make clear that the model Q cannot be adapted to wireless charging either. This makes any line of attack against claim 7 starting from model Q impossible."

    I agree that that the comment is an indication that model Q is perhaps not structurally closest, but I don't think the comment means that it would be impossible to redesign model Q. The commenter was asking about upgrading an existing car, not designing a new one. I argued that model P showed that it was possible to use wireless charging for a car, and the same was indicated by Annex 5 (licensing car technology, I think). Annex 5 also provided a motivation to implement wireless charging. "It is a lot of work" is not really an argument against inventive step.

    My problem with using model P was that I felt there was no indication that it used the relevant standard (even though it was sort of implied). Of course, updating a standard is probably much easier than updating a charging system. In the end I just thought departing from model Q felt more natural.

  7. Claim 5 requires an electrical connection outside the vehicle to be made inactive. I felt that the only real disclosure was in model P which indicated that the power switch in the charging terminal (component outside vehicle) can be switched off. Therefore I went for an inventive step attack starting from model Q and incorporating therein the software of model P

    1. For the 'outside the vehicle' aspect in claim 5, I used Annex 7, par. [7] as evidence for CGK that the electrical connection to the grid should be switched off in the charging terminal, and that that is possible with the RFC-7511-x standard (Annex 7, par. [6]; this standard is used by Model Q according to Annex 6, par. [6]).

    2. I went along that line too. But just saying it's not technical is not enough. You have to put the non-technical aim in your OTP and then show how the skilled person would solve it. A reference to the (public) standard described in A7 and implemented in the Model P vehicle will be needed, which then leads to substantially the same attack.

      Delete
    3. The DeltaPatents analysis for claim 7 seems to argue that model P is adapted for selective charging based on price information, and that hence model P discloses a method of selective charging based on price information (which is the subject-matter of claim 7):

      "Since model P is compatible with the standard RFC-7511-x, it is already adapted for price-dependent charging, and therefore has the additional functionality of claim 7."

      I am not sure that is a valid argument.

      Besides, Annex 7, par. [7]-[9] only disclose the microprocessor of the *charging terminal* being enabled to receive a signal indicating the price of electricity, and selectively charge based on that price information. Although a wireless link with the car (either model Q or P) is disclosed, it is not directly and unambiguously disclosed that the on-board computer of the car is configured to receive the price signal and to act on that.

      So, I now think that it may have been intended to use the car's on-board computer as the processing unit receiving the SSR signal, and the charging terminal's microprocessor as the processing unit deciding on the selective charging (wherein Annex 7 would have to be used as evidence of the charging terminal disclosed in Annex 6).

      Delete
    4. @Gerben indeed, A7 seems to refer to the charging terminal. In the attack, one would thus probably need to argue that the claim's charging system is anticipated by the combination of the charging terminal and the charging functionality of the car (which should be allowable - the term 'system' allows such a distributed implementation). Our attack in the post above doesn't address this complexity.

      Delete
  15. I have a question regarding the novelty attack against claim 5: In my view, A6 (Q model) does not disclose directly an unambiguously the a switch „outside of the vehicle“ is actuated to stop the charging, but only that the system decides to stop (somehow). It is however general knowledge that for security reasons the switches have to be turned off (see A7). Due to this, I made an inventive step attack using A6 + general knowledge, evidenced by A7 instead of a novelty attack, because general knowledge may not be used to close gaps regarding disclosure. Anyone else did this or thinks it is a valid point?

  16. Regarding claim 1 (fallback option): I see that A3 can be considered CPA and A3 + A5 is a strong attack. However, the other way round, i.e. A5 + A3 is basically equally strong. In this case, the distinguishing feature is „2 coils instead of 1 coil with reverse windings“ and this is obvious from A3 stating somewhere in the beginning that 1 coil with reverse windings can be replaced easily by 2 coils. Then, since the attack is successful, A5 also qualifies as CPA (case law of BoA), and we have the situation that A3 and A5 are both valid CPAs. I wrote down both attacks in the exam because the client said that it is extremely important for them that claim 1 is destroyed. Anyone else did this or thinks it is a valid point?

      I actually also understood the Client´s letter to mean that they downloaded the digital copy of the podcast on April 30, 2020 from the podcloud (which is mentioned in A6, Abs. 1 as well). I thought that this was the reason why the client explicitly stated: "We also have a digital copy of the podcast downloaded from https://www.podcloud.com/BBC9/programmes/b07dx75g/20200430.ogg". The link seemed to indcate April 30, 2020 as download date.

      With regard to the COMVIK-approach to the inventive step attack on claim 6. I took A1, Abs. 29 to mean that the decision making step of claim 5 (and thereofre claim 6+5) is non-technical in nature and does not contribute to the technical character of the invention. A1, Abs. 29: "The processing unit continuously receives and continuously evaluates the measurement value. This enables automation of the mental act of deciding whether the battery should be charged or not. However, this does not yet solve the technical problem of inadvertent field exposure in the charging area." So long story short: I also used the COMVIK approach for the attack on claim 6.

    4. It is True that A1 Last paragraphs contain hints (several times referring to mental act automatization) to attack IS of claims 5-7 on the basis of non contribution to IS of non Technical features, thus one has to base this approach on lack of IS and not on lack of Technical character (the method being implemented by a computer)

When assuming that the whole podcast including Model P was available on April 30, Model P could be used instead of Model Q in the novelty attack on claim 5. Model P seems to be clearly novelty destroying.

However, claim 7 also claims a “method according to claim 5, in which the charging system is the charging system according to claim 4, in which the received signal is representative of the price of the electrical energy to be used for charging the battery.”
    The charging system of claim 4 is disclosed by A5. Claim 5 discloses a method for controlling a charging system, which is known from the Model Q. Model Q is compatible with the RFC-7511-x standard, which is suitable for both wired and wireless charging.
    I would have understood the situation to mean that the Model Q device cannot be easily adapted. However, the person skilled in the art can very well apply the teaching regarding the method for operating the Model Q to the device according to A5. No structural measures are required on Model Q, as the method is simply applied to another device (charging system) that already has the necessary structure. Claim 5 does not refer to a special device (charging system), so it can be assumed that this method of control is not easily applicable to other devices. This is also evident from paragraph 6 of the A6, where it says that the Model Q was not yet designed for wireless line transmission but was already designed for wireless data transmission. This shows that these two measures are independent of each other. Since the charging system is not further defined in claim 5, a routine activity is to apply the control method to a specific charging system.
    In summary, my assessment would be that the combination A6 + A5 works, but the device must correspond to that of A5 and the Model Q should not be used for defining the device (charging system).
    The problem-solution approach would also lead to this, since the distinguishing features would be those that enable contactless power supply. The person skilled in the art would therefore use the device from A5 to carry out the method steps according to A6 (Model Q).
    The price issue could then be solved using the COMVIK approach.
    In my opinion, that would also make sense from an examination perspective. The COMVIK approach is used exactly to the extent that it is stated in the guidelines, without the need for in-depth knowledge of computer-implemented inventions.

    1. Hi Matthias, I agree with you that a skilled person would combine A5 with the Model Q of Claim 6. It is a simple combination and can be adapted to each other. Your analysis makes sense and I think you can also appeal if the examiner deduct your mark.

    2. @Matthias, interesting line of attack, we just discussed this but our concern would be that claim 7 is limited (through claim 5) to charging an electric vehicle and A5 (robot mower) probably does not match the definition of an electric vehicle.

    3. @Nico Cordes, @Lio thank you for your answer! I really appreciate that you took the time reading my statement and commenting it!

      Since A5 [1] states “… Although a robot mower is not a car we’ve put the latest technology from automotive manufacturers and other high-tech companies into our latest model”. I argued (something like) that the person skilled in the art looking for way to apply the method for controlling a charging system to a contactless power supply would read A5 since it deals with contactless power supply as stated in [2] (system for resonant wireless charging) and would apply it for cars because of [1].

    4. I have also used A5 as CPA, since I looked up the word "Vehicle" in my Cassell Dictionary during the exam: "n. any kind of carriage or conveyance for use on land, having wheels or runners".

      Based on this definition, i assumed that the robot of A5 could also be interpreted as a vehicle, since it carries rechargeable/replaceable batteries (+ oiling/cleaning kit, + extra blades, etc.), hence being ANY kind of carriage for use on land having wheels!

  29. The difficult partial first application problem in C and D in the same way in the same EQe sitting? Strange choice… the usual design principles in the D paper is that individual D1 questions are independent from eachother and do not test the same legal principle, and the D2 is designed such that going wrong with one specific discussion / one legal topic has hardly any knock-on effect on the rest of the paper - couldn’t one expect that these design principles also apply w.r.t. the various papers of the EQE in one specific year/sitting, esp as far as relating to difficult legal principles?

    1. The difficulty with the legal aspects of paper C1 was that you have to realise and deal with many things (effective date of C1 as filed and C2, intervals, patentee back up C1 with a different effective date than C1 as filed, A2 priority doc being 54(2) prior art for C2 and C3, but only 54(3) for the optimal amended C1 and non-novelty destroying , thus making necessary a IS attack over this amended C1)when one usually knows that he cannot spend so much time on the legal aspects of paper C... so you'd probably miss something and would probably end up not doing one of the 2 expected IS attacks...

  30. After that, one could expect a more simple legal part on C2, but again the A6 reference was kind of tricky and not seing well some of its implication could lead candidates to miss one of the expected novelty attacks. And even the last 2 expected IS attacks were not easy to deal with in the last hour of such a marathon...

  31. I attacked claim 4 with A5.

    I also attacked claim 5 with A5, as you have also considered. In my view, the only step of the claim I wasn't sure about was "deciding" by the system, because we were not told if the robot decides not to drive into the charging station based on the information the there is an object. But it's logical to assume that it doesn't.

    If claim 4 and 5 are both not novel over A5, surely claim 6 also can't be.
    I used A5 for almost every claim.. It was stage but I would stand by it. The claims were super general/broad, especially 5 and 6.

  32. Dear deltapatents,
    With regards to claim 6 I have taken the same approach as some other fellow candidates here; started from A5 as CPA, and combined it with model P of A6.
    Do you believe this combination to be completely wrong?
    Could I get any points for this attack?

    Arguing inventive step in claim 7 based on RFC-7511-x is quite the stretch to me. First you have the argument concerning wether the standard is at all implied the model P. There is no reference whatsoever to the fact that OS-corp generally copies over well accepted features for future models.
    But even if you accept the premise that the model P implies the standard, you have the following quote from A1 [33] about the effect of using price as signal: "This provides a solution to the problem of reducing costs". So the applicant itself describes the problem as "reducing costs", which to me means that the effect is purely financially motivated. Thus if you follow COMVIK, you wouldn't proceed to the could/would part of the argument but would have to exit and simply recited the non-technicality of the feature in and of itself and also that it does not contribute to any further technical effect. Using the congestion of the grid may certainly be a technical effect but this effect may not be relied uppon according to G2/21: "A patent applicant or proprietor may rely upon a technical effect for inventive step if the skilled person, having the common general knowledge in mind, and based on the application as originally filed, would derive said effect as being encompassed by the technical teaching and embodied by the same originally disclosed invention". There is no other effect mentioned concerning the price signal so the proprietor may only rely on the financial effect.
    To me, there can only be the COMVIK attack on claim 7.

    1. The Guidelines describe how to apply what we call the 'COMVIK approach' in https://www.epo.org/en/legal/guidelines-epc/2022/g_vii_5_4.html. Because the price-dependent charging requires some actual configuration of the charge control system, this looks like option (iii)(c), wherein you need to include the non-technical aim in your OTP (see also G‑VII, 5.4.1).

      For me the OTP would then be something like "How to adapt the Model P charging system and provide price-dependent charging?". The public RFC-7511-x standard, evidenced by A7 provides a known and obvious solution to this OTP.

      It may not be completely clear if A6 discloses that the Model P already uses this standard (it probably does, but this may not be directly derivable from A6), but in view of A6[2] (the usual wireless data connection for software updates) and A6[20] (software updates are easier), it would be a minor workshop modification to implement the RFC-7511x standard that they already used in their previous model.

      Certainly not an easy argument, but not all parts of all attacks need to be easy. You only need 45/50 marks. I'm sure that any attack that discusses the (non-)technical character of the missing feature and uses the RFC-7511x standard from A7, without ignoring that it is only a 54(3) document, will receive a majority of the available marks.

    2. Go Chargers, Go18 March 2024 at 15:44

      But (iii) c) wouldn't be applicable because (iii) c) requires that the differentiating feature contributes to the technical character (i.e., acquires technical character based on the rest of the claim). If you do PLA step by step, you end up with this:

      The feature in question is "using price as indicator" (it's the only differentiating feature over the P-model). The effect is "charging can be inhibited if the price is higher than a predetermined value" (A1 [33]). The problem to be solved is "reducing costs" (A1 [33]). Now you're at the point where the differentiating feature does not contribute to a technical goal but only a non-technical one. You also have no other differentiating features thus the objective problem can only be formulated in terms of a non technical problem. Hence the non-technical differentiating feature can not be used in limiting an otherwise technical problem.

      Thus (iii) c) is not applicable as this requires the differentiating feature to acquire technical character. In this case, the feature doesn't acquire technical character and (iii) b) is applicable.

      Just realized you also had the other features from the detector as differentiating, so it seems you are right here.

  35. Glad that claim 7 was expecting another fully reasoned-4th Inventive step attack rather than the 'no technical features' route.

    Was worried for a moment that the paper wasn't difficult enough as it is...

    1. I would say that the fact there were 4 expected IS attacks was not the problem, the problem that each of these 4 were kind of hidden. For example A3+A5 against C1: if you did not take the time to consider the patentee's possible answer to your opposition and cut the claim as he would probably do during the course of the opposition then you would not see that one.

  37. The Examiners'Report for paper C comes without a model solution...

    However, the latter is required acc Art. 6(6) REE: "After the examination, the Examination Board shall transmit to the Examination Secretariat a report on each examination paper (examiners' report) and a model solution prepared by the relevant Examination Committee. The report and the model solution will be published in an examination Compendium to enable candidates to prepare for future examinations as specified in the IPREE."

    I would assume that the model solution for C 2024 will be provided at a later moment, so as to comply with Art. 6(6) REE and to allow to understand the expected answer-in-full.

    1. agreed. I find it vague with just pointers to closest prior art without indication of the secondary documents and facts needed. They leave that to the candidate's answer. In previous years, the candidate's answer was a representative "good" answer, and not necessarily an ideal or perfect solution (they used to print the marks) - I wonder if this has changed. It would be good to know how many marks the model answer received, or even better - where they lost points.

  39. I think there are several places in the Examiner's report that could certainly be used as arguments on appeal. For exmaple, the client asking for all fallback positions in claim 1 to be argued against, but marks seemingly only being awarded for one of the fallback positions. Additionally, I believe that Rule 25(7) IPREE has been breached in the Examiner's Report.

  40. Am I missing something or the total amount of marks awarded in the compendium is 97 ?

  41. Dear all, for claim 1 i did 3 attacks of novelty about A2 54(3) and the priority of A2 54(2) for 3 fallback positions:
    - Claim as filed
    - Claim as amended
    - Claim with 10-20% CO and 30-40% Fe
    Please, give me your opinion; i did not get any points for claim 1; a novelty attack could be possible?
    I am thinking to file an appeal.
    Many thanks

    ReplyDelete
  42. I did the same, and got 3 (out of 23 points). priority of A2 is 54(3), as published 23.7.20 vs effective date of 14.3.20 of opposed patent. Since it's 54(3), then a non disclosed disclaimer excluding 30% Fe is allowable.
    I find it also extremely unfair not to give a single point, but still, that's the mistake.
    I'm also wondering how to proceed.
