Summary judgment of patent invalidity granted in favor of Finnegan client SinterFire Corporation

Judge Terrence McVerry of the Western District of Pennsylvania issued an order granting summary judgment of patent invalidity in favor of Finnegan client SinterFire Corporation. In the case, Delta Frangible Ammunition, LLC accused SinterFire of infringing a patent for a frangible bullet and a method of making it. SinterFire requested reexamination of the Delta patent, and the claims asserted against SinterFire were finally rejected in the U.S. Patent & Trademark Office. SinterFire had attempted to stay the litigation pending the results of the reexamination, but the district court denied SinterFire’s motion for a stay.
