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 English High Court has upheld the decision of the UK Intellectual Property Office to refuse the grant of a patent for the treatment of inflammatory bowel disease (IBD) with zinc (El-Tawil v The Comptroller General of Patents [2012] EWHC 185 (Ch)). Although the case does not break new ground, it provides a useful review…
Gemcitabine is part of the family of nucleosides which are compounds constituted of two chemical parts: a sugar bound to a nucleobase through a glycosidic bond.

This is to report on a new tendency in the jurisdiction of the Federal Patent Court to use the prerequisite of enabling disclosure (Art. 83 EPC) as an unpredictable rule of reason for patentability.

The Borgarting Court of Appeal overturned the district court decision which revoked the patents in suit for lack of inventive step.

The patent concerned claims a method of cooling animals characterized in that the animals are cooled in a milking stall so that the animals go to the milking stall spontaneously. The patentee added a disclaimer of therapeutic use. The claim covered only carrying out the invention on animals that are neither in a pathological state…
In this case the Court held that a previous patent application and other scientific publications which did not disclose the invention in a manner sufficiently complete for it to be carried out by a person skilled in the art, could not influence the novelty of the invention for which that patent application was later filed….
Do we need a Community Patent? Do we need a European Patent Litigation System? Or does the current fragmented system have a hidden wisdom behind it? Judge for yourself!
This judgement is one of many issued in the worldwide litigation pending between Novartis and Johnson & Johnson concerning Novartis’ patent for ophthalmically compatible extended wear contact lenses. The decision contains a recapitulation of all possible grounds for invalidity of a patent. The Court rejected the detailed claims of invalidity for lack of sufficiency, dealt…
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…
