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.
On 20 December 2017, the Court of Justice of the European Union (CJEU) confirmed that the term of a supplementary protection certificate (SPC) can be corrected to bring it into line with CJEU case law at any time before expiry of the SPC.
Following on from the decision in Seattle Genetics (C‑471/14) in 2015, which provided welcome clarity on which date should be used as the date of the first marketing authorisation (MA) for the purposes of calculating the duration of an SPC, this week’s decision should drive consistency in the application of Seattle Genetics by national patent offices across the EU. In Incyte (C‑492/16), the CJEU has ruled that an SPC holder can apply to rectify the duration of an SPC to bring it into line with Seattle Genetics at any time before expiry of the SPC, even if the period for appealing the decision under national legislation has passed.
