2008-1156 Flashmark Tech v. GTech

Posted on | February 21, 2008 | No Comments

ED/TX 2:06-CV-00205

Flashmark sued GTech on 5,109,153, related to articles with radiant energy responsive material and canceling such articles using radiant energy.  These articles could be checks, stock certificates, stamps, etc.  Judge Clark (based on patent, prosecution history and prior art) held that “radiant energy” was limited to energy from the electromagnetic spectrum and did not include energy transferred by conduction.  Flashmark then stipulated that GTech did not infringe and brought this appeal.
