About this event

Earlier this year in June, the UK Supreme Court handed down the long-awaited judgment in Regeneron Pharmaceuticals Inc v Kymab Ltd [2020] UKSC 27. The Court, by a majority of four to one, found Regeneron's antibody patents invalid for insufficiency, thus overturning the Court of Appeal’s decision. In the Court’s view, a patent claim lacks sufficient support if it is not enabled across its entire scope - since the patent bargain requires the monopoly granted to match the contribution made to the art.

But was the Supreme Court right? Can a principle of general application now be patented? And if so, how?
