Evolusion Concepts, Inc. owns U.S. Patent No.

8,756,845, titled “Method and Device for Converting Firearm with Detachable Magazine to a Firearm with Fixed Magazine.” In the main case before us, Evolusion sued Juggernaut Tactical, Inc. in the Central District of California , alleging infringement of claims 1–3 and 8–10 of the ’845 patent. On the parties’ cross-motions for summary judgment regarding infringement, the district court granted Juggernaut summary judgment of non-infringement . Evolusion Concepts, Inc. v. Juggernaut Tactical, Inc., No. 8:18-cv-01378, 2021 U.S. Dist. LEXIS 77792, at *27 (C.D. Cal. Apr. 5, 2020) (Juggernaut Decision). The court’s key ruling was that the term “magazine catch bar” in the asserted claims of the ’845 patent excludes a factory- installed magazine catch bar. Id. at *13–22. That claim construction concededly precludes literal infringement, the court held, because Juggernaut’s products use the factory-

installed magazine catch bar. Id. at *22–23. The court also determined that Juggernaut does not infringe under the doctrine of equivalents. Id. at *23–26.

On Evolusion’s appeal, we hold that the term “magazine catch bar” in the asserted claims includes a factory- installed magazine catch bar. We therefore reverse the grant of summary judgment of non-infringement, reverse the denial of summary judgment of direct infringement as to the independent claims 1 and 8, and remand for further proceedings in Appeal No. 21-1987, which is the appeal in the Juggernaut case. We also vacate and remand in Appeal No. 21-1963, which involves a separate, related case, discussed near the end of this opinion.

A

The ’845 patent describes a device and method for converting a semi-automatic rifle with a detachable magazine to one with a fixed magazine. ’845 patent, col. 2, lines 3–5. A detachable magazine allows a user to fire the weapon until the magazine is depleted, then simply release the magazine , insert a new magazine, and resume firing. Id., col. 1, lines 22–27. A fixed magazine, in contrast, can be removed and replaced only by disassembling certain nonmagazine parts of the firearm, slowing the rate of fire. Id., col. 1, lines 50–53; col. 2, lines 20–28. The specification explains that firearms with detachable magazines are likely to face increased legal restrictions. Id., col. 1, lines 63–64. In particular, the specification notes the introduction in Congress of a bill to enact the Assault Weapons Ban of 2013, which would have banned semi-automatic weapons with detachable magazines. Id., col. 1, lines 30–59.

The patent describes a “standard OEM [original equipment manufacturer] semi-automatic rifle” as having a “magazine catch assembly” containing several components. Id., col. 2, lines 35–53. It then describes “[t]he invention”

4 EVOLUSION CONCEPTS, INC. v. HOC EVENTS, INC.

as a “permanent fixture added to a semi-automatic firearm by removing the standard OEM magazine catch assembly and installing the invention.” Id., col. 2, lines 55–58. At least in “one aspect of the present invention,” the resulting firearm contains “a lower receiver, a magazine catch bar, and an upper tension bar.” Id., col. 2, lines 65–67. The magazine catch bar can be attached to the lower receiver of the firearm and fit within a recess of the magazine well. Id., col. 2, line 67, through col. 3, line 2. The upper tension bar on the lower receiver applies pressure against the firearm ’s upper receiver, rendering the magazine catch bar immovable . Id., col. 3, lines 2–6. The magazine can be released only when the upper receiver is separated from the lower receiver. Id., col. 4, line 64, through col. 5, line 4; id., figs. 1 & 2. The specification also discusses a method of installing the invention, comprising removing the entire factory-installed magazine release button assembly, installing a magazine catch bar onto the lower receiver, and installing an upper tension bar onto the lower receiver. Id., col. 3, lines 48–65.

The ’845 patent has three independent claims. These claims are:

1. A firearm with a fixed magazine comprising a lower receiver having a magazine well configured to receive a magazine with a side-locking recess with a recess in the magazine well a magazine catch bar securely attached to the firearm , said magazine catch bar resting within the magazine side-locking recess an upper tension bar which extends towards and contacts the upper receiver. 8. A device for converting a firearm with a detachable magazine into a firearm with a fixed magazine comprising

EVOLUSION CONCEPTS, INC. v. HOC EVENTS, INC. 5

A magazine catch bar securely attached to the lower receiver of said firearm, said magazine catch bar resting within the magazine side-locking recess An upper tension bar which extends towards and contacts the upper receiver. 15. A method for converting a firearm with a detachable magazine into a firearm with a fixed magazine comprising Removing the factory installed magazine release button assembly Said removal comprising the steps of depressing the magazine release button to a sufficient depth to permit the factory installed magazine catch bar to extend beyond the magazine well of the lower receiver, rotating the factory installed magazine catch bar in a counterclockwise fashion until the factory installed magazine catch bar is unthreaded from the factory installed screw end of the magazine release button, removing all parts of the factory installed magazine release button assembly Installing a magazine catch bar to the lower receiver of the firearm, said magazine catch bar resting within the magazine side-locking recess Installing an upper tension bar to the lower receiver of the firearm, said upper tension bar extending towards and contacting the upper receiver.

Id., col. 7, lines 27–35; col. 8, lines 4–10; col. 8, lines 47–67 (emphases added).

6 EVOLUSION CONCEPTS, INC. v. HOC EVENTS, INC.

B

In August 2018, Evolusion sued Juggernaut for infringement of claims 1, 8, and 15 of the ’845 patent based on Juggernaut’s manufacture and sale of its “Hellfighter Mod Kits,” which convert a firearm with a detachable magazine into a firearm with a fixed magazine. Juggernaut asserted invalidity as an affirmative defense and filed a counterclaim for a declaratory judgment limited to non-infringement . Subsequently, Evolusion dropped its assertion of method claim 15 and added assertions of infringement of dependent claims 2–3 and 9–10 (apparatus claims). In claim-construction proceedings from May to July 2019, the only phrase for which the parties sought a construction was “upper tension bar,” but the court decided that no construction was needed.
