In most systems, a patent is valid for 20 years from the filing date of the patent application. Patents are granted with a presumption of validity but no patent is safe from being challenged and declared (partially) invalid by national courts or, in the case of European patents, revoked by the European Patent Office. Often, a claim of invalidity of a patent is a reaction to an action of the patentee, in particular an infringement action.
It is hard to think of a recent SPC case before the UK courts where the judge has not had to refer questions to the CJEU in order to either clarify the terms of the SPC Regulation or the CJEU’s earlier interpretations. This necessity has arisen at an early stage in an action between Actavis…
and Carissa Kendall-Palmer In HTC Corporation v Gemalto SA and HTC Corporation v Gemalto NV [2013] EWHC 1876 (Pat), Mr Justice Birss ruled upon the validity and infringement of two telecommunications patents concerning smart/chip card technology. The Claimant came to the High Court of England and Wales seeking revocation of the patents; the Defendant counterclaimed…
Introduction In my previous post of 2 August 2013 I made passing reference to the recent decision of the English Court of Appeal in the Copaxone litigation. This case was an appeal of the decision of Arnold J (previously reported here) where he found Yeda’s patent valid and infringed. With permission of the court, Mylan…
It could be argued that 2013 is proving to be somewhat unkind to UK patentees when it comes to the issues of sufficiency and priority. On 25 June 2013, in a typically comprehensive judgment running to some 90 pages, Arnold J held that Janssen’s patent was invalid for insufficiency. The relevant facts were as follows:…
and Bernd Kröger. A combination of two pharmaceutical ingredients, i.e. leflunomide and teriflunomide is to be considered obvious if the person skilled in the art uses an obvious process to obtain leflunomide that automatically results in – even with a certain delay – both components due to a chemical reaction.

In a combined patent infringement and nullity case, the Svea Court of Appeal upheld the validity of Roche Diagnostics’ European patent as far as Sweden was concerned, but held, other than the District Court, that the alleged infringer did not infringe the patent at issue. The Court of Appeal further held that a patent can…
In its “Leflunomid” decision of 24 July 2012 (Case X ZR 126/09), the FCJ declared a patent claim to be invalid which covered a combination of leflunomide and teriflunomide, on the grounds that it had long been known in the prior art (for 100 years) that some leflunomide spontaneously and unavoidably converts teriflunomide over time…
The Court held that a decision by the EPO relating to the UK designation was not capable of challenge. In any event, the procedure chosen by the claimant to challenge the decision (an application to correct the UKIPO register based on Rule 50 of the Patents Rules 2007) was wrong, because it required the consent…
The complexities of European patent architecture raise a number of issues relating to the interface between opposition proceedings before the European Patent Office (“EPO”) and infringement proceedings before national courts. A recent case has raised one of such issues, namely: what the impact should be of the revocation of the patent by the EPO in…
by Henrik Timmann There is a saying in Germany: Two lawyers add up to three different opinions. Well, for a long time the Federal Patent Court seemed to have been inspired by this saying when deciding on the reimbursement of lawyers’ fees in nullity actions. Background Most of you will know about the bifurcated system…
