Robinson Arms, manufacturers of the XCR have filed suit yesterday in US District Court for Utah against Remington, Bushmaster, Rock River Arms, and Magpul Industries based on alleged infringement of their patent (Multi-caliber ambidextrously controllable firearm #7,596,900) issued 6 October, 2009 and initially filed in August of 2003.
Specifically, the weapons alleged to have violated Robinson’s patent are the Remington/Bushmaster ACR, Magpul Masada/Massoud, and the RRA LAR-8. All of these weapons feature a magazine release that is manipulated by the trigger finger from within reach of the trigger guard as well as a similar bolt hold open device. We have read the complaint and it is fairly ambiguous as the which patent claims they allege were violated.
Both Bushmaster and Remington are part of the Freedom group, owned by Cerberus Capital Management. So for taking on Freedom Group I give them an “E” for Effort. Of note is the timing of the suit, just days before SHOT Show as well as Robinson’s announcement on their website that they would be exhibiting after all in a booth (#20034) shared with Serbu.
