Sufficiency of disclosure

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.

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. As any nucleoside can have two isomers (the alpha-anomer and the beta-anomer) depending on the orientation in space of the glycosidic bond, it must be clarified that Gemcitabine is…

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. Based on a Federal Supreme Court decision of 2001 (“Taxol”), it had been established case law in Germany that a patentee…
