3. First application
3.2. Identity of applicant
In T 5/05 the opposition division had concluded that neither of the two claimed priority applications qualified as the first application within the meaning of Art. 87(1) and (4) EPC 1973 on the grounds that two inventors and part of the subject-matter were the same as in an earlier previous application. As the filing date of that application was more than twelve months prior to the filing date of the contested patent and the application had been "made public", the same invention of the same inventors could no longer serve as a basis for claiming priority.
The board, however, stressed that priority could be based only on earlier applications filed by the applicant of the European application or by his predecessor in title. Moreover, only such applications could meet the further requirement, derivable from Art. 87(4) EPC 1973, that an application giving rise to the priority right had to be the first application by the applicant or by his predecessor in title in respect of the invention. The inventor was not relevant. Applications filed by various applicants figured alongside one another as state of the art within the meaning of Art. 54(2) or Art. 54(3) EPC 1973. The board also rejected the respondent's argument that the economic aspect was relevant to the requirements relating to priority and that the two wholly owned subsidiaries of the same parent company were not independent of each other in view of their association through the parent. Legal acts were in principle attributable to the (legal) person who had performed them Exceptions to this needed a legal basis, which did not exist in the law relating to priority.
In T 788/05 the proprietor had been co-applicant in a previous European application D1 with an earlier priority date than that of the patent in suit. The appellant/opponent argued that since the proprietor was also designated as applicant in D1, it had to be regarded as the "person" referred to in Art. 87(1) EPC 1973 regardless of the designation in D1 of a second applicant. Since, moreover, the invention was the same in both documents, D1 had to be considered as the first application. Therefore the priority claimed for the application in issue was not valid and D1 was prior art under Art. 54(2) EPC 1973.
The board held that the term "a person" in Art. 87(1) EPC 1973 (or "an applicant" in Art. 88(1) EPC 1973) implied that the applicant was the same for "the first application" (or "previous application" in Art. 88(1) EPC 1973) and for the later application for which a priority right was claimed. In the case of D1, the priority right belonged to the two applicants simultaneously, unless one decided to transfer his right to the other, who then became his successor in title and this before the filing of the later application. No evidence of such a transfer had been submitted. Since the application in issue was only filed by one applicant, D1 could not represent the "first application" within the meaning of Art. 87(1) EPC 1973. The priority date was valid and D1 represented state of the art under Art. 54(3) EPC 1973. The disclaimer introduced during the examination proceedings to restore the novelty of claim 1 vis-à-vis D1 was also accepted by the board.
