UNITED STATES DISTRICT COURT DISTRICT OF NEW JERSEY

LEXINGTON LUMINANCE LLC,

Plaintiff, Civil Action No. 22-3787 v. OPINION BULBRITE INDUSTRIES, INC.,

Defendant.

John Michael Vazquez, U.S.D.J. This case concerns Defendant Bulbrite Industries, Inc.’s (“Bulbrite”) alleged infringement of Plaintiff Lexington Luminance LLC’s (“Lexington”) patent. Currently pending before the Court is Defendant’s motion to dismiss Plaintiff’s Complaint. D.E. 7. The Court reviewed the parties’ submissions,1 and decided the motion without oral argument pursuant to Fed. R. Civ. P. 78(b) and L. Civ. R. 78.1(b). For the reasons set forth below, the motion is GRANTED.

1 Defendant’s brief in support of its motion will be referred to as “Def. Br.” (D.E. 7-1); Plaintiff’s opposition will be referred to as “Plf. Opp.” (D.E. 15); and Defendant’s reply will be referred to as “Def. Reply” (D.E. 16). I. FACTUAL BACKGROUND AND PROCEDURAL HISTORY2 Lexington is the owner of U.S. Patent No. 6,936,851 (the “‘851 Patent”), entitled “Semiconductor Light-Emitting Device and Method for Manufacturing the Same.” Compl. ¶ 7. The United States Patent and Trademark Office (the “PTO”) originally issued the ‘851 Patent on August 30, 2005, and then reissued the patent on December 5, 2014, after an ex-parte

reexamination. Id. ¶¶ 7-8; Ex. 1 (D.E. 1-2).3 The reissued patent remains valid and enforceable and sets out 18 claims. Id. ¶ 9; Ex. 1. The ‘851 Patent teaches an improvement in the manufacturing of semiconductor light- emitting devices (“LEDs”). See Ex. 1 at 11, col. 1, ll 8-10. 4 LEDs generally consist of materials deposited on a base material known as a substrate. When the substrate material and the deposited layer material have different crystal structures that are incompatible in their atomic arrangements, a lattice mismatch may occur. Id. at 11, col. 1, ll. 18-22; see also Def. Ex. 5 at 39-40. A lattice

2 The factual background is taken from Plaintiff’s Complaint, D.E. 1 (“Compl.). When reviewing a motion to dismiss for failure to state a claim, a court accepts as true all well-pleaded facts in the Complaint. Fowler v. UPMC Shadyside, 578 F.3d 203, 210 (3d Cir. 2009). A court may also consider any document integral to or relied upon in a complaint and take judicial notice of public records, such as prosecution history available on the U.S. Patent & Trademark Office’s Public PAIR site. In re Burlington Coat Factory Sec. Litig., 114 F.3d 1410, 1426 (3d Cir. 1997); see also Genetic Techs. Ltd. v. Bristol-Myers Squibb Co., 72 F. Supp. 3d 521, 526 (D. Del. 2014), aff'd sub nom. Genetic Techs. Ltd. v. Merial L.L.C., 818 F.3d 1369 (Fed. Cir. 2016) (citations omitted) (“A court may also take judicial notice of the prosecution histories, which are ‘public records.’”); Uniloc USA, Inc. v. ADP, LLC, 772 F. App'x 890, 898 n.3 (Fed. Cir. 2019) (“The prosecution history is part of the intrinsic record of the patent” and “thus subject to judicial notice and may be considered in our de novo review of the district court['s]” ruling on a motion to dismiss).

3 The Court’s citations to “Ex. __” correspond to the exhibits to Plaintiff’s Complaint. See Ex. 1– 16 (D.E. 1-2–1-17). The Court’s citations to “Def. Ex. __” correspond to the exhibits to Defendant’s brief and reply in support of this motion. See Def. Ex. 1–11 (D.E. 7-3–7-11; D.E. 16- 2–16-3). All page numbers cited correspond with those in the ECF header.

4 Exhibit 1 includes the originally issued patent and the reissued patent, thus certain column numbers appear more than once. For clarity, the Court includes the ECF page number in addition to the column and line numbers when citing to the ‘851 Patent. mismatch creates a strain where the materials meet, which generates structural defects, also known as lattice defects. Ex. 1 at 11, col. 2, 3-6; Def. Ex. 5 at 40. These defects multiply and propagate into the light-emitting active layer, resulting in premature degradation of the LED. See Ex. | at 11, col. 2, Il. 6-8; Def. Ex. 5 at 40. The ‘851 Patent offers a solution to the lattice mismatch problem by using a substrate with a “textured district defined on the surface of said substrate” to direct lattice defects to the sides and thus reduce the defect density in the active layer. Ex. 1 at 12 col. 3, Il. 33-35; Def. Ex. 5 at 40. The textured district is comprised of “a plurality of etched features such as trenches and mesa having a smooth rotation of microfacets” without a prescribed angle of inclination. Ex. 1 at 11— 12, col. 2, ll. 22-25, col. 3, Il. 35-49. A “first layer [1s] disposed on said textured district,” and this first layer is comprised of “a plurality of inclined lower portions,” “whereby said plurality of inclined lower portions are configured to guide extended lattice defects away from propagating into the active layer.” Ex. 1 at 18, col. 1, Il. 31-43. The first layer also has “a light-emitting structure containing an active layer” disposed on it. /d. at 18, col. 1, ll. 39-40. The patent provides several cross-sectional views to demonstrate how embodiments of “trenches having a sloped etching profile” guide dislocations to designated locations and reduce defects in the active (top) layer of the LED, including Figures 1C, 2A, and 2B.

Id. at 4-5. Lexington alleges that Bulbrite “has infringed and/or continues to infringe” at least claim 1 of the ‘851 Patent by “among other things, making, using, offering for sale, selling, and/or importing light-emitting diode (“LED”) lighting products containing LEDs that infringe the ‘851 Patents (the ‘Accused Products’).” Jd. § 11. Claim 1 reads as follows: 1. A semiconductor light-emitting device comprising: a substrate; a textured district defined on the surface of said substrate comprising a plurality of etched trenches having a sloped etching profile with a smooth rotation of microfacets without a prescribed angle of inclination; a first layer disposed on said textured district; comprising a plurality of inclined lower portions, said first layer and said substrate form a lattice mismatched misfit system, said substrate having at least one of a group consisting of group III-V, group IV, group II-VI elements and alloys, ZnO, spinel and sapphire; and a light-emitting structure containing an active layer disposed on said first layer, whereby said plurality of inclined lower portions are configured to guide extended lattice defects away from propagating into the active layer. Ex. 1 at 18, col. 1 1. 25 —col. 2 1. 42.

The “Accused Products” include, but are not limited to, those identified by Lexington in the exemplary charts submitted with its Complaint. Id. ¶ 12; see Ex. 2–16 (D.E. 1-2–1-17).5 Lexington alleges that since on or around July 26, 2019, Bulbrite has been aware of the ‘851 Patent, and has had actual notice and knowledge of its infringement of the ‘851 Patent, based on a letter that Lexington sent to Bulbrite. Id. ¶¶ 15, 17; see also Def. Ex. 7 (D.E. 7-9). Lexington also

alleges that Bulbrite has had knowledge of the ‘851 Patent and its alleged infringement of the patent since at least June 14, 2022, when Lexington’s Complaint was filed. Id. ¶ 16.
