Kymab wins UK Supreme Court case against Regeneron


Dublin-Ireland, 24 June 2020: Malin Corporation plc. (Euronext Growth Dublin:MLC) (Malin), a company investing in highly innovative life sciences companies, today is pleased to note that Kymab Limited (Kymab), a clinical-stage biopharmaceutical company and one of Malin's Priority Assets, has won its UK Supreme Court case against Regeneron Pharmaceuticals, Inc (Regeneron). The Supreme Court held that all of the claims of two patents (European Patents EP(UK) 1 360 287 and EP(UK) 2 264 163, the 'Murphy patents') owned by Regeneron that were asserted against Kymab are invalid. Regeneron initiated these patent infringement proceedings against Kymab in 2013. The Supreme Court's decision upholds the February 2016 UK High Court decision to revoke the claims and reverses the UK Appeal Court's determination that they were valid. 


This ruling in the UK follows Regeneron's unsuccessful attempt to invalidate five Kymab patents in the US covering genetically modified mice and the human antibody therapeutics produced from these mice earlier this year. Regeneron was also recently unsuccessful with challenges to Kymab patents in Japan and Australia.


"We congratulate the Kymab management team and board for their resilience in defending this case in the UK since 2013 and are delighted with the UK Supreme Court's ruling invalidating Regeneron's patent claims," said Darragh Lyons, Malin Chief Executive Officer. "We look forward to further progress from this Priority Asset, namely the important clinical data from Kymab's pipeline over the coming months, particularly the Phase 2a clinical data for the anti-OX40 ligand-targeting antibody in atopic dermatitis."


A copy of Kyamb's press release is available to view here:


Kymab is a clinical-stage biopharmaceutical company based in Cambridge, UK, developing a deep pipeline of novel antibody-based therapies in a broad range of indications. The Company generates its product candidates using its proprietary, integrated platforms collectively called IntelliSelect®. Kymab's platforms have been designed to maximise the diversity of human antibodies produced in response to immunisation with antigens. Selecting from a broad diversity of fully human antibodies allows for the identification of antibodies with optimal drug-like properties.
