Heizer Defense files lawsuit against Doubletap Defense

Heizer Defense Pocket Shotgun

Heizer Defense are suing Doubletap Defense in Federal Court, claiming ownership of patent No 8,495,831. This patent was applied for by DoubleTap Defense in 2011 and approved by the USTPO earlier this year.

Heizer Defense and Doubletap Defense collaborated on the design before falling out and going their separate ways. Doubletap Defense is selling the Doubletap pistol and Heizer Defense will soon be launching the Heizer Defense Pocket Shotgun, both are based on the same basic design.

From Heizer Defense’s press release …

In a continued effort to protect their product development and engineering efforts, Heizer Defense, LLC has filed a complaint in the United States District Court for ten counts.

This includes declaration of inventorship and transfer of rights for patent No 8,495,831 and for the declaration of invalidity and unenforceability, or alternatively correction of inventorship and transfer of rights for design patent No. D686,685.

We would expect the lawsuit to establish, among other things, that Charles Heizer, Founder of Heizer Aerospace, is an inventor for this patent.

The defendants of the complaint are Doubletap Defense LLC, f/k/a Heizer Technologies, LLC; Central Holding Corp.; Raymond Kohout, and Marvin Dufner.

The parties have agreed to mediation that is scheduled to take place in November.

    I can see why two companies might want to go to court to claim they had nothing to do with this gun, but not the other way round!

    • Ryan

      LMAO! Awesome!

  • Tim Pearce

    I hope Heizer the best of luck.

  • Frank Martin

    And So.. The public who were wanting to see this pistol come to light. will turn out to be the loosers.. Too bad.

    I can understand the lawsuit.. I really can.. but to me.. Heizer failed to deliver.. and now wants to keep DoubleTap from making a profit on a concept.

    The price tag never made sense to me. I actually was considering a Double Tap in .45ACP with ported barrels. But I was planning on an MSRP in the $300 range. There is no justification for the price. There are too many (pun intended) other derringers and pocket guns on the market.
    They had a wave of favorable reviews and publicity. I actually liked what I saw. But they screwed up, did not produce, priced themselves out of the market, and have no one else to blame.

  • J.T.

    I don’t see this ending well for Heizer.

  • me ohmy

    frankly….both guns suck,IMHO, and a small 380 or 9MM is way more powerful and easier to have repeat shots, for the first 21 feet of minute of bad guy, they wont feel the difference.
    the idea of a single or double barreled 410 shotgun in your pocket for slim pocket printing instead of a small auto is a complete NON STARTER.
    I am not impressed with the design from EITHER of these companies..
    I’ll stick with my S&W 19 357 2 1/2 barrel length, yeah it’s fatter…but it’s a reliable six shots with at least a 158 grain bullet at 1100 FPS, for goblin eradication purposes.

      The HD Pocket Shotgun is .410, the Double Tap is chambered in pistol calibers, the idea behind it is obviously to have a really small gun that doesn’t print with a powerful cartridge, most likely a 45 ACP, since the capacity is the same for all calibers for obvious reasons, it’s going to be their more popular model IMO, specially among guys with a “45 or nothing” attitude but want to carry a super concealable pistol. The Pocket Shotgun I don’t get, I suppose it’s made mainly as a “survival” gun, but I have doubts regarding its usefulness that would explain the lawsuit.

  • Geoff a well known Skeptic

    This looks like old tech to me. And this style pistol has been notoriously unreliable since Hi-Standard. I don’t understand what could be patented. Geoff Who notes “patents” have become the holy grail of Billionaire Lawyers.

    looks like something that belongs ina chicks makeup bag

    Overpriced, correction: WAY overpriced, silly gun you would never find in the pocket of anyone serious about self defense when SO MANY OTHER options that are just as compact, less expensive, and offer more firepower are out there. My Kel-Tec P32 handgun for example. 10 shots of .32 ACP in a gun every bit as thin and light as this abomination. Sure the double tap is a .45 ACP, but it’s a well known fact .45 ACP from short barrels isn’t nearly as good as from longer barrels. The internal ballistics suffer quite a bit.
