An EPO board of appeal expressed its opinion that EBA case law implied that no further use should be made of the three-part “essentiality test” of T 331/87, for deciding whether removal of a feature from a claim complies with article 123(2) EPC. The only test endorsed by the EBA was the “gold standard”. The…

A board of appeal of the European patent office held that a decision to reject an opposition with grounds based on an improperly corrected version of the patent as granted maintains the text used in the decision to grant, without the corrections. A decision of the examining division to correct the text after grant by…

The enlarged board of appeal (EBA) of the European patent office effectively ended the possibility of poisonous priority. The EBA held that entitlement to partial priority may not be refused for a claim encompassing alternative subject-matter by virtue of generic expressions (generic “OR” claims) if the priority document discloses part of that subject matter in…

Although it did not admit a broader claim 1, an EPO board of appeal allowed an auxiliary request wherein claim 1 as granted was replaced by a combination of independent claims from different first instance requests.

The other party also needs to be notified of complaints about the work…

An EPO board held that observations filed by third parties during inter partes appeal must be disregarded by the board, unless they concern amendments during opposition or appeal, in which case the board has discretion whether or not to consider the observations in the examination of the amendments.

The Board of Appeal held that “Biogen insufficiency”, the situation in which the full extent of the monopoly claimed exceeds the technical contribution to the art, is not a distinct ground for invalidity from “classical insufficiency”. Further, the fact that a skilled person is not able to carry out the invention without using the disclosed…
