Friday, March 10, 2017 T 1434/13 - When priority becomes important: D1 is published in the priority year

 

Fig. 2 of D1 (WO2006/095202)

Only in few number cases the right to priority is extensively examined - in general only if there is prior art that has been published in the priority year. In this opposition appeal there was a document on file (D1) that was published in the priority year of the disputed patent. An interesting thing to mention is that document D1 is a PCT application of the same applicant as the owner of the disputed patent. In the opposition proceedings, the Division decided that the patent did not enjoy the right of priority from the two priority documents and, thus, that the claim as granted lacked novelty. In this appeal, the Board repeated the work of the Opposition Division. The Board wrote down an interesting reasoning because different aspects played a role: features were disclosed in the figures, features were not disclosed as a whole in a single embodiment and it seems that essential elements of the priority documents are not the claims (in other words: the priority documents disclose different inventions). 

Thursday, February 02, 2017 G 1/15 (2) - The decision on partial priority

The Order was already issued by the Enlarged Board in November last year, but the full decision and its reasoning became available only just now. The Enlarged Board considered the EPC priority provisions of Art. 87(1), 88(2)-(3) and 89, Paris Convention Priority and the FICPI Memorandum in detail to come to its decision. The right to claim priority and its effect/ purpose (reason 4) led the Enlarged Board to conclude that a generic claim encompassing alternative subject matter may not be refused partial priority, provided that said alternative subject-matter has been disclosed for the first time, directly, or at least implicitly, unambiguously and in an enabling manner in the priority document. No other substantive conditions or limitations apply in this respect. 

Friday, September 11, 2015 T 1155/11: the Board introduces a new document - unravelling a web of priority claims

 

The Board of appeal introduced an additional document that was not mentioned before in the Examination procedure. I didn't see this before and I was surprised. The Board writes in its "Communication of the Board" (dated 3/2/15, sent to the appellant (applicant) together with the invitation to attend oral proceedings):
"The Board notes that in addition to D1 and D2, there are several European patent applications from the same applicant describing subject-matter very close to that of the present application. [...] At least some of those European patent applications have earlier priorities than the second priority date of the present application, 16 April 2003, and describe similar subject-matter. Such applications may be relevant under Article 54(3) EPC in case the first priority date is found to be invalid or to cover only part of the claimed subject—matter."
Subsequently a new document D9 is introduced in the proceedings which claims priority from three priority documents and one of these documents is also a priority application of the patent application that is subject of this Appeal. It seems that, in this decision, the Board tries to unravel the web formed by multiple applications of the same Applicant that claim priority of a multitude of priority applications.
In this decision the subsequent priority claims are relevant:
The patent application that is subject of this appeal is filed on 1 Oct 2003 and claims priority from Korean priority patent application P1 of 17 Feb 2003 and P2 of 16 Apr 2003.
Document D9 (EP1573723), as introduced by the Board, is filed on 1 Oct 2003 and claims priority from Korean priority patent application P3 of 21 Feb 2003, P4 of 3 Mar 2003 and also of P2 of 16 Apr 2003.
If the priority claim from P1 for some of the features of the amended claims from P1 is not valid, and these features are described in D9 and also in one of P3 and P4, then document D9 is an Art. 54(3) EPC document for the amended claims. In the decision a certified translation of P4 and P2 is introduced in the proceedings as respective documents D10 and D11.
