Opinion

IN THE UNITED STATES DISTRICT COURT January 04, 2021 FOR THE SOUTHERN DISTRICT OF TEXAS Nathan Ochsner, Clerk HOUSTON DIVISION

SHOTKAM LLC and DAVID ALEXANDER § STEWART, § § Plaintiffs/Counter-Defendants, § § v. § CIVIL ACTION NO. H-20-1070 § TACHYON, INC. and RAYMOND C. LING, § § Defendants/Counter-Plaintiffs. § MEMORANDUM AND OPINION This patent-infringement case involves weapon-mounted technology designed to improve a shooter’s accuracy. David Alexander Stewart’s U.S. Patent No. 8,908,045 (the “‘045 Patent”) claims a system for capturing, analyzing, and displaying data about a shooter’s aim at a moving target. Shotkam, LLC owns the ‘045 Patent and, using the patented technology, manufactures and sells a weapon-mounted “digital video camera.” (Docket Entry No. 52 at 9–10). The camera takes a short video of each shot and uses a visual indicator to show the shot’s location relative to the target. Stewart owns other related patents, including U.S. Patent No. 9,546,846 (the “‘846 Patent”), which is a “video camera gun barrel mounting system.” (Docket Entry No. 1 at ¶ 15 (uncapitalized)). Shotkam and Stewart (together referred to as “Shotkam”) allege that Tachyon, Inc. and its president and chief executive officer, Raymond C. Ling, (together referred to as “Tachyon”) infringed Claims 1 and 20 of the ‘045 Patent with their “2020 GunCam for Clays & Hunting.” (Docket Entry No. 1 at ¶ 22). The parties have asked the court to construe Claims 1 and 20, and Tachyon has moved for summary judgment based on its proposed construction. (Docket Entries Nos. 47, 49, 51, 61). The court held a Markman hearing on December 16, 2020. The disputed issue is whether the phrase “at least one of [item], and [item]” is conjunctive or disjunctive. If the term is conjunctive, then Shotkam’s factual allegations fail to allege patent infringement by Tachyon. If the term is disjunctive, infringement is not precluded. Based on the motion, the briefs, the record, the arguments of counsel, and the applicable law, the court finds and concludes that the disputed term is disjunctive. Applying that construction,

the court denies Tachyon’s motion for summary judgment. The reasons are set out in detail below. I. Background A. The Parties Shotkam is a limited liability corporation organized under Florida law, with its principal place of business in Boca Raton. Stewart owns the ‘045 Patent and is the owner and managing member of Shotkam. (Docket Entry No. 1 at ¶¶ 5–6). Tachyon is a corporation organized under Texas law. Ling is its president and CEO. (Docket Entry No. 11 at ¶¶ 7–8). B. The Infringement Allegations Shotkam alleges that Tachyon’s “2020 GunCam for Clays & Hunting” directly infringes

the ‘045 Patent because it uses “a camera device[] and a point of aim compensation and correction system . . . made pursuant to at least independent claims 1 and 20 of the ‘045 Patent.” (Docket Entry No. 1 at ¶¶ 22, 24–29; Docket Entry No. 35 at 2). Shotkam also alleges that Ling “has been and is inducing infringement of the ‘045 Patent by actively and knowingly inducing others to make, use, sell, or offer for sale” the infringing product. (Docket Entry No. 1 at ¶¶ 30–35). Shotkam seeks injunctive relief, actual and exemplary damages, and attorneys’ fees. (Id. at 10). Shotkam alleges that Tachyon has known of Shotkam’s patent rights since at least February 2017, when Shotkam sent Tachyon and Ling a letter discussing alleged similarities between Tachyon’s products and the Shotkam ‘846 Patent claims. (Id. at ¶17; Docket Entry No. 11 at ¶ 17). That letter did not discuss the ‘045 Patent. C. The Disputed Terms The parties dispute two terms in Claims 1 and 20 of the ‘045 Patent. Those claims read as follows, with the disputed terms in bold:

1. A camera device comprising: a camera mounted on a shooting device to capture video discharge data of the shooting device associated with at least one of a sight picture, a target lead, and a shooting technique, the camera is independent of a targeting system of the shooting device, and the video discharge data allows a shooter to estimate a lead given to a target in both a case where the target was hit and where the target was missed, and also to estimate a shooting device alignment relative to a target in both the case where the target was correctly aimed at and where the target was incorrectly aimed at; at least one of a [reticle] generating system to add a [reticle] in a field of view towards a discharge end of the shooting device, and an indicator generating system to add a graticule in the field of view towards the discharge end of the shooting device, to indicate an aim point of the camera; and an alignment system to adjust a position of the aim point of the camera relative to the aim point of the shooting device.

20. A point of aim compensation and correction system comprising: a camera device mounted on a shooting device for capturing an image; at least one of an optical alignment mechanism includes one or more of an optical bore sighting, a shooting device’s fixed sight, a scope mounted on the shooting device, a generated indicator, and a generated overlay, and a laser alignment mechanism with one or more of laser bore sighting, a laser integral to the camera device, a laser separate from the camera device, to adjust and offset an aim point indicator of the camera device and an aim point of the shooting device by programming a correction offset data into the camera device; and wherein the offset data is processed by the camera device to align the aim point of the camera to the aim point of the shooting device.

(‘045 Patent, Claim 1, Col. 19:49–Col. 20:3; Claim 20, Col. 22:28–45).1

1 The ‘045 Patent uses the term “reticule” instead of “reticle.” Although “reticule” is an alternative spelling for “reticle,” it also—and primarily—means a small drawstring purse or handbag. See Reticule, Merriam- Webster, https://www.merriam-webster.com/dictionary/reticule (last accessed December 30, 2020). For clarity and consistency, the court uses the term “reticle” throughout this opinion. To resolve the first dispute, the court must determine whether “at least one of” in Claim 1 precedes a two- or three-item list. That is, the court must determine whether “an alignment system” is included in the list that follows “at least one of,” as Tachyon claims, or is not part of that list, as Shotkam claims. To resolve the second dispute, the court must determine whether “at least one of . . ., and”

in Claims 1 and 20 is construed as conjunctive or disjunctive. That is, the court must decide whether “at least one of [A], and [B]” means: (a) “at least one of [A] and at least one of [B],” as Tachyon claims; or (b) “at least one of either [A] or [B], or both,” as Shotkam claims. D. Procedural History Shotkam filed this suit in the Eastern District of Texas in December 2019. (Docket Entry No. 1). In March 2020, the parties jointly moved to transfer to the Southern District of Texas. (Docket Entries Nos. 8, 9). Tachyon answered and asserted affirmative defenses and counterclaims. (Docket Entries Nos. 10, 11). In May 2020, the court granted Shotkam’s motion to dismiss Tachyon’s counterclaims and denied the motion to strike the defenses. (Docket Entries

Nos. 30, 45). Tachyon’s summary judgment motion is based on its proposed construction of the ‘045 Patent applied to the record evidence. (Docket Entry No. 47). E. The Record The summary judgment record consists of the following: • the ‘045 Patent, issued December 9, 2014, (Docket Entries Nos. 47-1, 49-1); • a portion of Stewart’s application for the ‘045 Patent, (Docket Entry No. 49-4); • Ling’s declaration, (Docket Entry No. 47-2); • Stewart’s declaration, (Docket Entry No. 49-6);

• William R. Trueba, Jr.’s declaration, (Docket Entry No. 49-2); • Michael F. Price’s declaration and supplemental declaration, (Docket Entries Nos. 49- 8, 49-9);
