D. Priorität

Catchword:

1. For the question of whether the applicant is "successor in title" within the meaning of Article 87(1) EPC, it is sufficient for the applicant or patent proprietor to demonstrate that the assignment of the priority right was effective before the subsequent application was filed. The law does not set forth any other condition. In particular, the assignment need not be effective before the filing date of the subsequent application. (see point 2.3). 2. In the context of in-person oral proceedings, a request of a party for a hybrid format to allow the representatives to attend the hearing in person and other attendees to attend remotely should normally be granted only if the participation of the person for whom the access by means of videoconferencing technology has been requested is related to a person whose participation in the oral proceedings is relevant to the case, in particular to the decision to be taken at the oral proceedings (see point 1.).

Catchword:

For assessing an intermediate generalisation in an amended claim for compliance with Article 123(2) EPC it has to be established whether, because of this generalisation, the subject-matter of the claim extends beyond what was, be it explicitly or implicitly, directly and unambiguously disclosed to the person skilled in the art using common general knowledge in the application as filed. This is the "gold" standard for assessing any amendment for its compliance with Article 123(2) EPC (G 2/10, point 4.3 of the Reasons). If an amended claim comprises only some features of an originally disclosed combination and the features left out of the claim were understood, by the person skilled in the art, to be inextricably linked to the claimed ones, the claim includes subject-matter extending beyond the application as filed. This is the case if the person skilled in the art would have regarded the omitted features to be necessary for achieving the effect associated with the added features. In such a situation the amended claim conveys the technical teaching that the effect can be obtained with the claimed features alone, which is in contrast with and extends beyond the original disclosure that the whole combination of features was needed. The criteria for assessing the validity of a priority for the subject-matter of a claim as set out in G 2/98, no matter whether or not the claim includes intermediate generalisations, correspond to the "gold" standard for assessing any amendment for its compliance with Article 123(2) EPC. In view of Article 88(4) EPC, it is not required that this subject-matter be disclosed in the form of a claim or in the form of an embodiment or example specified in the description of the application from which the priority is claimed. In the passage in point 4 of the Reasons of G 2/98 these items, as derived from the expression "in particular", are simply listed as exemplary parts of the application documents. (Reasons, points 2.4 and 3.2)

Catchword: 

In view of the principles of multiple priorities and partial priority: undisclosed disclaimer based on a disclosure in an earlier application by the same applicant not allowed.

Catchword:

If the patent proprietor introduces various differences between the definition of a certain compound in a granted claim and that in the priority application and if despite these differences, the patent proprietor, in arguing that the effective date of the subject-matter of the granted claim is the claimed priority date, asserts that the compound of the granted claim is the same as that disclosed in the priority application, it is the patent proprietor who bears the burden of proving this assertion (point 2.13 of the reasons).

Catchword:

I. The European Patent Office is competent to assess whether a party is entitled to claim priority under Article 87(1) EPC. There is a rebuttable presumption under the autonomous law of the EPC that the applicant claiming priority in accordance with Article 88(1) EPC and the corresponding Implementing Regulations is entitled to claim priority. II. The rebuttable presumption also applies in situations where the European patent application derives from a PCT application and/or where the priority applicant(s) are not identical with the subsequent applicant(s). In a situation where a PCT application is jointly filed by parties A and B, (i) designating party A for one or more designated States and party B for one or more other designated States, and (ii) claiming priority from an earlier patent application designating party A as the applicant, the joint filing implies an agreement between parties A and B allowing party B to rely on the priority, unless there are substantial factual indications to the contrary.
