According to article 83 European Patent Convention (EPC): ‘The European patent application shall disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.’ For the disclosure to be sufficient at least one way of carrying out the invention should be disclosed in the description such that it is apparent to the skilled person how to put the invention into practice. Lack of sufficiency is a ground for revocation of a European patent in opposition proceedings at the European Patent Office, and for invalidation by national courts.
The Court of Appeal upheld the High Court’s finding that Novartis’ patent for ophthalmically compatible extended wear contact lenses was invalid for insufficiency. The Court of Appeal held that the patent does not teach which materials described in the specification are suitable for extended wear lenses, nor does the patent enable the skilled person to…
A 1 July 2009 decision of the Tribunal de Grande Instance of Paris illustrates how the French courts proceed when they are seised of a nullity claim of the French designation of a European patent against which opposition may be filed or opposition proceedings are pending.
Sufficiency of disclosure is one of the requirements for the grant of a European patent (Art. 83 EPC).

Two recent decisions of the Italian Supreme Court (no. 21835 of 14 October 2009 and no. 23414 of 4 November 2009) have tackled the issue of sufficiency in a peculiar manner, departing from previous case law.

In this case the Board ruled that features providing a displayed icon of a three-dimensional appearance have technical character and thus should be considered when assessing inventive step. According to the Board these features specify how the information is displayed and not what is displayed so that these features do not fall under the category…
In this case, the Board of Appeal had to decide whether a claim containing a feature for which the description contained erroneous figures only met the requirements of Article 83 EPC (sufficiency of disclosure) and Rule 27(1)(e) EPC 1973 (corresponding to Rule 42(1)(e) EPC 2000). The Board of Appeal decided that a patent application should…
In case of parallel proceedings before a national court and the Boards of Appeal, parties should inform both tribunals of this position as early as possible. In order to avoid duplication of proceedings, the parties should ask the appropriate tribunal for acceleration. Whether acceleration is requested by one party, or both or all parties in…
The Board of Appeal decided that the following applies as regards to sufficiency of disclosure: (1) the skilled person should be able to realise without undue burden substantially any embodiment falling in the ambit of a claim on the basis of the disclosure and/or common general knowledge; (2) the objection of lack of sufficient disclosure…
The High Court dismissed Novartis’ claim for infringement of its EP(UK) patent for ophthalmically compatible extended wear contact lenses. Although Novartis established that the defendants’ product falls within certain claims of the patent, and successfully resisted Johnson & Johnson’s novelty and obviousness attacks, the patent was found invalid for insufficiency. The Court held it would…
