On October 16th, MagPul filed a claim against Elite Tactical Systems for patent infringement in the Colorado District Federal Court.. The claim alleges that Elite Tactical Systems has infringed on three MagPul patents, 8,069,601, 8,635,796, and 8,839,543.

The initial claim is brief with few details, but nonetheless calls out all the magazines that Elite Tactical Systems currently offers:

Upon information and belief, Defendant Elite Tactical Systems Group, LLC
(“Defendant”) is a Wyoming limited liability company with a place of business in Tennessee, and a mailing address at P.O. Box 18511, Knoxville, Tennessee 37928. Defendant’s infringing products include, but are not necessarily limited to, the E.T.S. 30-round polymer magazine for AR-15/M16 rifles and carbines (with and without coupler), the E.T.S. 10-round, Pinned 30 Round Body polymer magazine for AR-15/M16 rifles and carbines (with and without coupler), and the E.T.S. 15-round, Pinned 30 Round Body polymer magazine for AR-15/M16 rifles and carbines (with and without coupler).

MagPul’s suit is a continued vigorous defense of their patents. Previously, MagPul had filed suit with four other companies for patent fermenting. We will follow the suit and keep you informed of the results.
