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.
In another post (here) I have discussed the procedure for seeking post grant limitation in the framework of Italian court proceedings, and the closing line of that post mentioned that another interesting point of discussion would be when such post-grant limitation should take effect vis-à-vis infringers. In fact, a few decisions have touched this issue…
A Turkish company active in the automotive sector filed a patent infringement action against a German global automotive company. The Turkish company alleged that a system used in the cars of the German company was infringing its non-examined patent granted by the Turkish Patent and Trademark Office (‘TPTO’). As a counter-attack, the German company and…
A jury’s verdict that snowmobile frame patents asserted against Arctic Cat were indefinite and invalid as anticipated or obvious was supported by substantial evidence. A federal district court correctly upheld a jury verdict invalidating two Bombardier Recreational Products Inc. snowmobile frame patents because substantial evidence supported the jury’s findings that Bombardier’s patent related to rider…
In a complex and interesting validity and infringement case, the Barcelona Court of Appeals (Section 15), Spain’s most experienced patent court, tackles a plethora of issues: linguistic interpretation of European patents; long-time tolerance of patent infringement; assignee estoppel vis-à-vis third parties; claim construction; and indirect evidence of (non)-infringement of a product claim in cases where,…

Anan Kasei and Rhodia (“Rhodia”) are respectively the proprietor and exclusive licensee of a patent for ceric oxide compounds for use in catalytic…
Among the flurry of pre-summer vacation judgments coming from the Patents Court is one from Mr Justice Birss (17 July 2019), concerning the validity of Hoffman-La Roche’s patent EP (UK) 2 007 809. EP’809 is a formulation patent for the monoclonal antibody vedolizumab, marketed as Entyvio® and used to treat ulcerative colitis and Crohn’s disease….
A further interesting decision handed down by the Judges of the English Patents Court prior to the Easter break was a judgment from Nugee J concerning proceedings between E. Mishan and Hozelock relating to a UK patent and European patent, both entitled “Expandable Hose Assembly”. E. Mishan (trading as Emson) claimed that Hozelock’s expandable garden…
In nullity proceedings initiated by Accord Healthcare (“Accord”) the District Court of The Hague has held Shire-NPS Pharmaceuticals’ (“NPS”) patent EP 1 203 761, the basic patent for an SPC covering cinacalcet, invalid for lack of inventive step and declared the SPC null. In short, the court considered that the (selection of) cinacalcet provided no…
Two recent decisions in the UK and Australia in the long-running pregabalin litigations demonstrate the different approaches in these jurisdictions to determine if a patent specification has sufficiently disclosed an invention. Readers will recall that the judgments concerned Warner-Lambert’s Swiss-style claims for the use of the compound pregabalin (marketed as Lyrica) in the treatment of…
With the Danish patent litigation community being limited in numbers and the pool of legal judges and expert judges available to the Danish specialty patents court being likewise limited in numbers, The Maritime & Commercial High Court (“MCC”) – along with its appellate branches – has long since decided that judges deciding an application for…
