Dom has been suspicious on the developments of the Adaptive Combat Rifle (ACR) which is hoped to be presented to the admiring masses during the Shot Show 2010. This has been discussed between him and Optimus Prime as he is keenly monitoring the real steel side of things. It seems that he is right with Robinson Arms suing Remington, Magpul, et al on a patent infringement case.

As posted here last 8 January 2010, the ACR is now being developed by Remington Arms due to some previous production problems, but as the intellectual property ownership gets murky as the ACR gets developed from Magpul, to Robinsons, then to Remington, a legal battle became inevitable.

Now, Defense Review gives us the news on this legal battle. Now, will the Remington ACR be still shown next week? Chances are, if the Robinsons gets a restraining order from the court preventing Remington to showcase the rifle, then prepare to wait for a long time (again) before this rifle gets into work.

As taken from Defense Review:

On January 4th, 2010, DefenseReview published a quick piece on the new “leaked” Remington ACR (Adaptive Combat Rifle) video. Well, something rather interesting has since occurred involving the ACR. According to RFC Express, a website covering “US Federal District Court, Recently Filed Cases”, a company designated as “RMDI, LLC” is listed as the Plaintiff in a federal lawsuit (Civil Action No. 2:10-cv-00029-DAK) vs. Defendant(s) Remington Arms Company, Inc., Bushmaster Firearms, Rock River Arms, and MagPul Industries. The “COMPLAINT FOR PATENT INFRINGEMENT” federal lawsuit was, according to RFC Express, just filed on Thursday, January 14, 2010 (yesterday) in a Utah District Court. Remington and Bushmaster are part of the Freedom Group, which is owned by Cerberus Capital Management, L.P.

RMDI, LLC is a limited liability company owned by Alex Robinson of Robinson Armament (ROBARM), maker of the XCR Modular Weapon System tactical rifle series. DefenseReview has been informed by Alex Robinson that the lawsuit involves a patent that Mr. Robinson has on an “ambidextrous magazine release (a.k.a. ambidextrous mag release) and bolt hold-open”, and that the firearms involved in the alleged patent infringement/violation are the Remington ACR (previously known as the Bushmaster ACR) 5.56mm NATO (5.56×45mm NATO)/.223 Rem. tactical rifle, MagPul Masada ACWS (from which the ACR was derived and developed), Rock River Arms (RRA) LAR-8 7.62mm NATO (7.62mm NATO)/..308 Win. rifle, and the MagPul Massoud 7.62mm NATO/.308 Win. rifle. The official lawsuit document confirms this.

The official lawsuit document, which Defense Review has legally purchased and downloaded from the RFC Express website, states that the lawsuit is over U.S. Patent No. 7,596,900 (the “’900 patent”) entitled “Multi-Caliber Ambidextrously Controllable Firearm,” issued on October 6, 2009 to inventors Alexander J.Robinson , Darin G. Nebeker, and Jon C. Holway. It further states that “Defendants are liable for infringement of the ’900 Patent pursuant to 35 U.S.C. § 271.”
