On 14 November, the Supreme Court handed down its judgment on the validity and infringement of the second medical use patent that protected Pfizer’s Lyrica® (pregabalin) for the treatment of various types of pain. In Warner-Lambert Company LLC v Generics (UK) Ltd (t/a Mylan) & Anor [2018] UKSC 56, the Court decided that the patent held by Warner-Lambert (a company in the Pfizer group) was invalid for insufficiency, because it did not render it plausible that pregabalin would be effective to treat all of the claimed types of pain. The Court also held that, had the claims been valid, they would not have been infringed by a “skinny label” generic version of pregabalin that had the protected indications carved out. However, the five judges of the Court were not in agreement on several key points.

Yesterday, a new global medicines patent database, the Patent Information Initiative for Medicines (Pat-INFORMED), was launched by WIPO and the International Federation of Pharmaceutical Manufacturers & Associations (IFPMA).

Pat-INFORMED is designed to help procurement agencies better understand the global patent status of medicines, for example to anticipate generic launch and to design tenders. It includes a free open access database of patent information, and a platform where procurement agencies can make direct enquiries to companies.

On the morning of 25 July 2018, the Court of Justice of the European Union (the CJEU) handed down judgment in Case C-121/17 Teva UK and Others v Gilead concerning the validity of Supplementary Protection Certificate (SPC) protection for Gilead’s combination HIV treatment TRUVADA (tenofovir disoproxil and emtricitabine). The CJEU held that an SPC can only be granted for a product if, in the basic patent on which the SPC is sought, that product “is either expressly mentioned in the claims of that patent or those claims relate to that product necessarily and specifically.” It is for the English High Court, as the referring court, to determine whether that test is met by Gilead’s patent in this case; however, the CJEU stated (on the basis of the information provided by the referring court) that it does not seem possible that the combination of tenofovir disoproxil and emtricitabine necessarily falls under the invention covered by Gilead’s patent.
