EQE Paper C 2015 - Carving out a solution


After the ski of paper B we get snowboards with paper C (English, French, German). Candidates faced claims with different dates, admissibility problems, added subject matter, multiple novelty attacks and the usual agonizing over the closest prior art.

Claim 1

This claim is a very broad, and gives little information on the relationship between the various elements. This should be used to do no less than three novelty attacks: a novelty attack on 54(3) document A6, a novelty attack based on A5 and a novelty attack based on the trade show Ski, Hop and Jump as evidenced by A2.

The novelty attack based on A2 is quite weak, as we hardly have evidence for the disclosure. The answer should make this clear, by presenting what little evidence we have now and offering to present additional evidence.

Claim 2

The novelty attacks of Claim 1 do not extend to Claim 2. Note, that the snow board of A2 is not unidirectional.

This leaves us with inventive step attacks. There are two potential closest prior arts: A2 and A3.

Starting from A3 would lead to a conventional inventive step attack with A4 as combining document.

Starting from A2 we have a number of problems. In theory we could finish this attack starting from A2 and combining with common general knowledge to change to board from freestyle to unidirectional. However, there are several drawbacks for this approach. First of all, evidentiary A2 is a weak document. Second, changing from freestyle to unidirectional may be quite a change. As the core determines the shape of the board, the entire board has to be thrown away and one has to start again from scratch.

Between these two options, the attack A3+A4 seems stronger, so we opt for this one.

Claim 3

There are no novelty attacks. Candidates for closest prior art are A2 (which for this claim is much stronger, as Claim 3 has a later effective date), and A3. Both documents miss the matrix, but A3 misses much more. Moreover, with A3 we have the problem of starting with the wrong type of snow board (unidirectional instead of freestyle). The attack based on A2 + A6 seems to work fine.

Claim 4

This is an 'or' claim because it refers back to two different claims: claims 2 and 3. These two variants should be attacked separately. Claim 4(3) was added during prosecution but does not have support. It can be attacked under A. 100(c). Claim 4(2) refers back to Claim 2 for which we already have an inventive step attack. Fortunately, the new feature of Claim 4 is part of the closest prior art, so the attack for claim 2 can be extended to claim 4(2).

Claim 5

This claim introduces a claimed object, a damper instead of a sports article. We find dampers in A2, A3, and A5. A2 is a weak document here, and misses the sensing, the filtering, and the frequencies. We discard this option. A3 shows sensing, but not together with dampening. A3 shows filtering but only for sensing not for dampening. A5 on the other hand has all features except the correct frequency. Moreover, A5 explains that the frequency can easily be changed, and that the damper may be used for other sports articles. It appears that A5 is thus the better closest prior art, A3 is then used as the combining document. A potential weak point of an attack based on A5+A3 is that A5 is only concerned with longitudinal waves whereas A3 needs damping for torsional waves. In the end the combination A5+A3 seems easier to make then the reverse one, so we opt for this.

Claim 6

There are two potential closest prior arts for this claim: A2 and A3. Although, easy to miss, A2 actually has every feature of claim 6 except the measuring step. A3 on the other hand, has the measuring step but also a teaching away against the piezoelectronic damper. The combination A2+A3 works thus much better than starting from A3.

In summary, our attacks are:

Claim 1: Novelty A2, A5, A6
Claim 2: Inventive step A3+A4
Claim 3: Inventive step A2+A6
Claim 4(2): Inventive step A3+A4
Claim 4(3): Added subject matter
Claim 5: Inventive step A5+A3
Claim 6: Inventive step A2+A3

EQE 2010: claim 1, 54(2)

With the new DeltaPatents website online we can start working at the content again. As promised, I will say something about the 54(2) attack on claim 1 of last month's EQE exam.

A 54(2) attack may either use novelty or inventive step. Before selecting a closest prior art or novelty destroying embodiment we first determine the claimed object, i.e. a liquid dispenser with a gaseous propellant. Then we try to find this object in the available 54(2) documents (A2, A3, A5). A2 is about a gas dispenser (first line of [0001]), A3 uses an aluminium bottle (first line of [0001]) and in A5 the trapping material is not coated on the wall ([0005] in combination with item 56 in the figure). It is clear that we cannot do a novelty attack and have to select a closest prior art.

EQE C 2010: claim 1, 54(3)

Claim 1 claims a liquid dispenser with a gaseous propellant. For finding all required attacks on this claim we first have to find out what documents we are allowed to use. After determining the effective date of claim 1 (filing date LU1) and looking at the relevant dates of the Annexes, we know that there are two 54(3) documents, A4 and A6, and three 54(2) documents.

First we try to find all 54(3) attacks by looking for claim features not disclosed in A4 or A6. For A6 the situation is pretty clear. A6 only discloses a valve and not a dispenser. We can (for now) disregard this document.
