Kymab Ltd has beaten back a challenge by Regeneron Pharmaceuticals Inc to its transgenic mouse technology for creating antibodies following a decision by the Supreme Court of the United Kingdom. The decision is important for Kymab, the smaller of the two companies, which has a pipeline of preclinical and early clinical antibody therapeutics to treat cancer and immune diseases. Regeneron had challenged Kymab’s foundational technology. But in an opinion delivered on 24 June, the UK court declared that claims made by Regeneron were not valid.
