ZymoGenetics (Seattle, WA, www.zymogenetics.com) has sued Bristol-Myers Squibb (New York, NY, www.bms.com) over alleged infringement of ZymoGentics’s fusion-protein technology patents. ZymoGenetics filed the lawsuit in the US District Court for the District of Delaware and is seeking injunctive relief and damages.
