Kymab has received permission to appeal the decision of the UK Court of Appeal to overturn the decision of the High Court trial judge, Mr. Justice Henry Carr, to revoke two patents owned by Regeneron that seek to cover genetically modified mice containing human antibody variable region loci and humanised antibodies from such mice.

Cambridge, UK; 30 November 2018: Kymab, a clinical-stage biopharmaceutical company developing fully human monoclonal antibody therapeutics, announces that it has received permission to appeal the decision of the UK Court of Appeal to overturn the decision of the High Court trial judge, Mr. Justice Henry Carr, to revoke two patents (European Patent EP(UK) 1 360 287 and EP(UK) 2 264 163) owned by Regeneron.

The patents in question seek to cover genetically modified mice containing human antibody variable region loci and humanised antibodies from such mice. The High Court decided on 1 February 2016, in agreement with Kymab, that Regeneron's patents were invalid as they failed to disclose sufficient information to allow the claimed inventions to be performed. The decision of the High Court was subsequently overturned by the Court of Appeal.

Permission to appeal to the Supreme Court has been granted on the grounds that the Court of Appeal wrongly interpreted and applied the law of insufficiency.
