Magpul Lawsuits: Additional Details

magpul logoMagpul filed lawsuits against four manufacturers as I reported last week.  Those lawsuits all allege patent infringement related to AR-15 magazines.

Reading the complaints filed in all four cases, Magpul cited a total of six different patents they allege have been infringed.  One of those patents, US Patent No. 8,069,601, is listed in each of the complaints, while the others are limited to specific cases.

The complaints do not list the specific details explaining how Magpul believes the products infringe on the patents.  As the cases advance through the legal process, it is possible additional documents will be filed with the court that further explain the alleged infringements.

Here is the breakdown of the complaints:

Magpul Industries v. Cole Industries

Magpul alleges the Cole A2 30-round magazine for the AR-15 rifle infringes US Patent No. 8,069,601 B1 (ammunition magazine for a firearm).

    if they are gonna pull a surefire and sue others as a business model to out spend them into stopping competition, I will cease to buy their products.

    • Why dont you stop supporting companies who cant design their own products? Me, I buy Troy Magazines, but still, I have no compassion for patent infringement. I dont even really like Magpul all that much, but how is them getting ripped off ok?
