The US Patent and Trademarks Office's Patent Trial and Appeal Board on Tuesday upheld the validity of a patent protecting Biogen's multiple sclerosis treatment Tecfidera (dimethyl fumarate) following a challenge by hedge fund manager Kyle Bass.
Biogen announced Tuesday that it has agreed to enter a $1.25-billion settlement and licensing agreement with Forward Pharma under which it will obtain an irrevocable license to all of the latter's intellectual property.
