Trubion Wins Genentech, Biogen Patent Case

Xconomy Seattle — 

Seattle-based Trubion Pharmaceuticals (NASDAQ: TRBN), the developer of targeted therapies for cancer and autoimmune diseases, said today it has won a patent dispute against Genentech and Biogen Idec. The dispute centers on targeted therapies designed to block a marker on cells, CD20, which is currently hit by Genentech and Biogen Idec’s rituximab (Rituxan). Trubion, which has developed its own CD-20 blocker, challenged a European patent held by Genentech and were successfully able to revoke it in September 2008. That ruling has now been upheld by a European appeals board, which had the final decision in the matter, Trubion said in a statement.
