On 22 June 2010, the English Court of Appeal handed down its judgment in yet another case involving stents in Occlutech v. AGA Medical. The appeal was dismissed with the result that AGA’s patent was held not infringed by Occlutech. The decision itself is interesting for three reasons: First, and most importantly, the decision contains…
The English Patents County Court is to appoint a new judge on the retirement of His Honour Judge Fysh QC in July of this year. The Patents County Court was originally established in 1990 under the Copyright, Designs and Patents Act 1988. It was designed to offer an alternative forum from the High Court (including…
In May 2010, in HTC Corporation v Yozmot 33 Ltd [2010] EWHC 1057 (Pat), the English High Court (Arnold J.) confirmed that it is in principle legitimate for a party to seek a judgment of the English Court on the validity of a UK designation of a European patent in the hope that the judgment…
Schütz owned two patents relating to the field of intermediate bulk containers or ‘IBCs’, which are large plastic bottles contained in cages and used to transport hazardous liquids.

The English Court of Appeal dismissed Novartis’ appeal against the finding of the Patents Court that Novartis’ patent for a sustained release formulation of fluvastatin was invalid for obviousness. The case was unusual because, at first instance, Warren J. had held the patent to be inventive on a conventional analysis but then went on to find it obvious using an acontextual approach. The Court of Appeal discussed the correct approach to the question of obviousness in English law, by reference to both the problem and solution approach developed by the European Patent Office and the established four-step approach developed by the English Courts in Windsurfing v Tabur Marine and Pozzoli v BDMO .
On any view, the world of international patents is fast-paced and constantly changing in shape. Barely a week goes by without an important development from a major national Court or the EPO in a significant area such as the allowability of claims to pharmaceutical dosage regimes or the patentability of computer software. The Patents Courts…
