Paper C 2017 Corkscrew

Here our fast attempt to C 2017 (paper here in EN and FR):

Claim 3(2): Added Subject-matter, Art.100(c), Art.123(2), metal necessary [0014]

Effective dates:
Cl. 1, 2, 3(1),4: P1 = 08.04.2010
Cl. 5-7: P2 = 28.03.2011

List of Evidence:
A2, A3, A5, A6: Art.54(2) all claims
A4 (the fair, not the document): Art.54(2) for claims 5-7

Other attacks
Claim 1: inv. step A6+A2, cork more stable, alternative solution (no spring)
(NA5 doesn't work. ridges not helical, not cork engaging, pitch undefined)

Claim 2: I've changed this based on the discussion below.
First option: inv. step A5 + A6 + A2
Alternative: inv. step A6+A2+A5, less force/effort for cork removal
(A3 misses the effect)
Probably only one option required. Probably 1st option is preferred.

Claim 3(1): inv. step A6+A2, A6 is already PET

Claim 4: inv. step A6+A2+A3, clover shape or 3/4 lobs from A3, better grip
(T641/00 doesn't work, technical effect present)

Claim 5: Nov A4 (A2 as evidence for reduced friction)
(NA2 doesn't work, no disc, no straight portion or no spiral portion)
(NA5 doesn't work, no coating on the spiral portion)

Claim 6: inv. step A4+A2, particularly good material for reducing friction, alternative for PFC
(A5+A2 may be possible, easier insertion, weaker, A5 not CPA)
(A4+A5 does not work, A5 misses the effect)

Claim 7: inv. step A4+A2, 'lower half', 'smoother insertion' (A2 [0005]), 'expensive' (A2 [0006]), compromise between low cost and low friction
(A5+A2 may be possible, easier insertion, weaker, A5 not CPA)

Looking forward to your comments,

C 2017: first impressions?

To all who sat the C-paper today:

What are your first impressions to this year's C-paper?
Any general or specific comments?

Was the number of claims as expected, or more, or less? And the number of prior art documents?
Were the various attack types well balanced - novelty, inventive step, added subject-matter, ...?
Was the described technology well understandable? For electronics/electricity attorneys, mechanics attorneys, chemists, biotech attorneys, ...?

How many marks do you expect to have scored?
What is your expectation of the pass rate and the average score?
How did this year's paper compare to the 2013 - 2016 papers (assuming your practiced those)

The paper and our answers

Copies of the paper will be provided on this blog as soon as we have received copies of the papers, in all three languages here (English, French and German).

The core of our answers will be given as soon as possible in a separate blog post.

We look forward to your comments!

Comments are welcome in any official EPO language, not just English. So, comments in German and French are also very welcome!

Please do not post your comments anonymously - it is allowed, but it makes responding more difficult and rather clumsy ("Dear Mr/Mrs/Ms Anonymous of 03-03-2015 03:03"), whereas using your real name or a pseudonym is more personal, more interesting and makes a more attractive conversation. You do not need to log in or make an account - it is OK to just put your (nick) name at the end of your post.

Please post your comments as to first impressions and general remarks to this blog.
Please post responses to our answer (as soon as available) to the separate blog post with our answer.

Thanks!
