T 0407/15 - Earlier application was assigned, but no proof that priority right was transferred too
In the present case, the validity of priority was important in view of a disclosure in the priority interval. The priority applications were filed jointly by three persons (the inventors), and identify "The University of Western Ontario" as assignee in a section entitled "Assignee information". The current Euro-PCT application was initially filed as an international PCT application by The University of Western Ontario, and indicates these same three persons as inventors. Despite having been invited to do so by the Board, the appellant failed to provide any evidence that a transfer of the priority right took place and that it was entitled to claim these priority rights. The Board argued that: "Both US applications 61/035 540 and 61/035 777 contain a section entitled "Assignee information", identifying "The University of Western Ontario" as assignee. This is, however, not sufficient to establish that the priority rights derived from either application have also been transferred to the applicant." "This is a consequence of the fact that the filing of a first application gives rise to two different and independent rights, namely the right to the application in question, and the right of priority. While the sections of the priority documents referred to above appear to provide evidence of a transfer of the right to a patent, it is silent as to any right of priority based on said filings."
