SIG SAUER, Inc Files P365 Magazine Patent Infringement Case Against Springfield, Inc

NEWINGTON, N.H., (May 11, 2021) – Today, SIG SAUER, Inc., filed a lawsuit in the United States District Court for the Central District of Illinois, Rock Island Division, alleging that Springfield, Inc. (Springfield Armory) infringes two SIG patents relating to SIG’s P365 magazine. 

The P365 has seen tremendous commercial success, due to the innovative design of the high-capacity magazine.  In its complaint, SIG alleges that Springfield Armory’s making and selling of certain “Hellcat” branded magazines infringes upon two SIG patents.  SIG SAUER is seeking injunctive relief, as well as monetary damages for Springfield Armory’s past and ongoing infringement.  

Ron Cohen, President and Chief Executive Officer, made the following statement:

“When the SIG SAUER P365 was introduced it took the market by storm as the most innovative high-capacity, micro-compact pistol to be introduced due to its magazine capacity, and quickly became one of the top selling handguns in the market due to this unprecedented innovation.  SIG is not a litigious company, but given the extent of infringement by Springfield, SIG has a responsibility to protect both our intellectual property and the significant investment we make to develop our innovative products.  As a company we are proud to yield more than 100 patents worldwide, with more than 40 patent applications currently pending, and we will protect the extensive research and design that goes into developing these patents rigorously.”

    Good for Sig because patent law REQUIRES the defense of patents in order to protect the patented products.

    After Springfield Arms’ owner Dan Reese was exposed by TTAG and others for funding IL state Dems and their anti-2A IL GDLA- I can’t support SA unless a totally new owner buys SA.

    Disclaimer: I own neither a Sig P365 nor a Springfield Hellcat. I cannot immediately compare the magazines of either.

    What I do know is Sig is not normally or particularly a litigious company. They also worked hard to develop the magazine in question and designed the pistol around it. Then SA just seems to amazingly figure out a competitive design. Interesting.

    Unrelated to the lawsuit: Sig makes it’s pistols in the US. Springfield makes it’s pistols, to include the Hellcat, in Croatia.
