Article summary

Life Sciences analysis: Rafi Allos, senior associate, and Kristjan Bloudoff, associate, of Allen & Overy LLP discuss the latest UK medical technology (UK Medtech) patent decision in which the High Court held that Roche Diabetes Care’s Accu-Chek Solo insulin pump did not infringe Insulet’s patent (either directly, indirectly, or by way of equivalence), and that the patent was invalid. Notably, the court held that both technical and commercial regulatory considerations can form part of the objective mindset of the skilled person or team when designing a medical device. The court also held that narrowing the disclosure in the patent specification by reference to the claims or a perceived commercial failing of the invention would be wrong, and that both the result and the means used to achieve the invention were all part of the inventive concept to be considered in the test for infringement by equivalence as set out in Actavis v Eli Lilly. This case also provides consideration of patent claim construction and interpretation following a review of the relevant legal principles, and an insight into the Shorter Trials Scheme (STS). or take a trial to read the full analysis.
