Tuesday, May 28, 2019 T 1218/14 - No accidental anticipation; relevant for inventive step?

Does the finding that (a disclosure in) a prior art document D1 does not qualify as an accidental anticipation (thus not allowing the use of an undisclosed disclaimer) because it does not fulfill the criterion laid down in G 1/03 that it is so unrelated to and remote from the claimed invention that the skilled person would never have taken it into consideration when making the invention, imply that it is automatically relevant for inventive step? Or, turned around, if it is found that the claimed subject matter is inventive in view of D1, does this mean that D1 is in fact irrelevant for inventive step, such that the criterion in G 1/03 is met and that D1 is an accidental anticipation after all?

Not necessarily - according to this decision. Herein, the Board argued that the requirement in G 1/03 that an accidental novelty-destroying disclosure has to be completely irrelevant for assessing inventive step is to be understood not as an alternative, or additional criterion, but as a consequence of the criterion that, from a technical point of view, said disclosure is so unrelated and remote that the person skilled in the art would never have taken it into consideration when making or working on the invention.

Consequently, if this criterion is met, it follows that said disclosure is completely irrelevant for assessing inventive step. However, not meeting said criterion does not necessarily imply the opposite, namely that the disclosure in question will contribute to a finding that inventive step is lacking.

Accordingly, in the present case, as D1 was considered to deal with a side aspect of the claimed subject matter, the patentee was not able to maintain his broader claims by disclaiming a relevant disclosure of D1; the subject matter of duly limited claims was however deemed inventive in view of D1 as secondary document.

Sunday, March 31, 2019 T 437/14 (Minutes of oral proceedings) - Disclaimer decision following the decision on its referral (G 1/16)

In this case, the Board referred questions to the Enlarged Board about the applicability of the gold standard disclosure test as defined in decision G 2/10 to undisclosed disclaimers (no), and the applicability of criteria as defined in decisions G 1/03 and G 2/03 (yes). The Enlarged Board handled the case as G 1/16 and answered that "For the purpose of considering whether a claim amended by the introduction of an undisclosed disclaimer is allowable under Article 123(2) EPC, the disclaimer must fulfil one of the criteria set out in point 2.1 of the order of decision G 1/03. The introduction of such a disclaimer may not provide a technical contribution to the subject-matter disclosed in the application as filed. In particular, it may not be or become relevant for the assessment of inventive step or for the question of sufficiency of disclosure. The disclaimer may not remove more than necessary either to restore novelty or to disclaim subject-matter excluded from patentability for non-technical reasons." The referring Board has no issued the Minutes of the subequent oral proceedings before it.

Tuesday, March 20, 2018 T 660/14 - an undisclosed disclaimer after G 1/16

In this appeal, the proprietor gave as a basis for the subject-matter of claim 1 of auxiliary request 4 meeting the requirement of Article 123(2) EPC that the subject-matter of claim 1 includes an undisclosed disclaimer. The undisclosed disclaimer was not of the most common type of disclaiming a Art.54(3) EPC prior right disclosure. The proprietor considered the alleged undisclosed features as either one or two undisclosed disclaimers. The proprietor submitted that the disclaimed feature/features provided no technical contribution to the claimed device, and had no real meaning apart from excluding an incorrect interpretation of claim 1, such that the requirements for disclaimers to be allowed under Article 123(2) EPC as mentioned in G1/16 were fulfilled. The Board of Appeal disagreed: according to the Enlarged Board of Appeal decision G1/16 (see e.g. Headnote), to be allowable under Article 123(2) EPC, the introduction of an undisclosed disclaimer may not provide a technical contribution to the subject-matter disclosed in the application as filed. In particular it may not become relevant for the assessment of inventive step (G 1/16 Reasons, point 49.1). 

Tuesday, November 15, 2016 Gold standard poll results

In T 437/14 the board of appeal referred questions on disclaimers to the enlarged board. The central question is how the gold standard of G 2/10 is to be squared with the disclaimers that are allowed for accidental anticipations under G 1/03. The case has been discussed in the comments, and various directions were suggested in which the enlarged board could go.

The past two weeks we placed a poll at our blog in which our readers could make their predictions. Polling is now closed and the results are in.

So there is a clear majority that does not expect that G1/03 is any in danger. I'm looking forward to the enlarged board's decision to see how well this poll matches reality.

Tuesday, October 25, 2016 T 437/14 - New Questions on Disclaimers referred to Enlarged Board

Is this still the same apple?

The disclaimer case G 1/03 seems to allow exceptions to Article 123(2) that 'Gold-standard' case G 2/10 does not allow. This board does not like it one bit:

"If one takes a bite out of an apple, what remains is recognisably no longer the same apple as the original one. Even though it is still an apple, the apple with the bite taken out of it cannot be regarded as explicitly or implicitly, but directly and unambiguously, "disclosed" in the original apple." (Reasons 8.1)

Claim 1 in this case includes two disclaimers to restore novelty against an accidental anticipation. This would be allowed under G 1/03. Is it also allowed under the more recent G 2/10? We will soon have a new enlarged board decision on disclaimers, joining the ranks of G 1/03 and G 2/10, because the following questions have been referred:

1. Is the standard referred to in G 2/10 for the allowability of disclosed disclaimers under Article 123(2) EPC, i.e. whether the skilled person would, using common general knowledge, regard the subject-matter remaining in the claim after the introduction of the disclaimer as explicitly or implicitly, but directly and unambiguously, disclosed in the application as filed, also to be applied to claims containing undisclosed disclaimers?

2. If the answer to the first question is yes, is G 1/03 set aside as regards the exceptions relating to undisclosed disclaimers defined in its answer 2.1?

3. If the answer to the second question is no, i.e. if the exceptions relating to undisclosed disclaimers defined in answer 2.1 of G 1/03 apply in addition to the standard referred to in G 2/10, may this standard be modified in view of these exceptions?
