After years of litigating members of the same 16-patent family, broadly directed to laptop computer locking assemblies, against ACCO Brands, Think Products Inc. has asserted one of them against Microsoft (1:21-cv-06757) in a new Northern District of Illinois case. The same patent is already in suit in one of three actions filed in the same district against ACCO; that litigation has been stayed to await the outcome of reexaminations before the USPTO. Think Products indicates in the new complaint that the asserted patent has just emerged from those proceedings.
