§ § § Civil Action No. ____________ § § JURY TRIAL DEMANDED § § § § §

PLAINTIFF’S ORIGINAL COMPLAINT Plaintiff Fluxwerx Illumination, Inc. (“Fluxwerx”) hereby asserts the following claim for patent infringement against Defendants OKT Lighting USA, LLC (“OKT USA”) and Shenzhen OKT Lighting Co., Ltd. (“OKT China”) (unless otherwise indicated, “Defendants”), and states as follows: NATURE OF ACTION 1.

This is an action for patent infringement based upon Defendants’ infringing

Fluxwerx’s intellectual property, including Fluxwerx’s patented LED luminaire design protected by U.S. Design Patent No. D747,539 (the “’539 Patent”). 2.

As a result of Defendants’ unlawful infringement, Defendants have been

wrongfully enriched, and Fluxwerx has been injured through loss of sales and good will, and seeks injunctive and monetary remedies under the federal patent statute, 35 U.S.C. §§ 284, 285, and 289.

Case 4:19-cv-01113 Document 1 Filed on 03/26/19 in TXSD Page 3 of 14

made the decision in 2010 to shift our direction, dedicating our resources to serving this market alone,’ says Zhang.” (https://www.oktlighting.com/products-about-okt.html). 9.

On information and belief, Defendant OKT USA is a subsidiary and agent for OKT

China, and sells, imports, resells, distributes, and warehouses products for OKT China at the direction of OKT China. 10.

On information and belief, OKT China has promoted its intention to present

products including the product accused in this action at the LightFair 2019, which infringes Fluxwerx’s intellectual property rights under the ‘539 Patent. JURISDICTION AND VENUE 13.

Plaintiff incorporates the preceding paragraphs herein by reference.

14.

This is an action for patent infringement brought under the patent laws of the United

States, 35 U.S.C. § 1, et seq. This Court has original subject matter jurisdiction over the claims in this action pursuant to 28 U.S.C. § 1331 (federal question), 28 U.S.C. § 1332(a)(2) (international diversity), and 28 U.S.C. § 1338(a) (patents). 15.

Venue is proper in this judicial district pursuant to 28 U.S.C. §§ 1391, 1400

because OKT USA is registered in the State of Texas as a limited liability company listing its principal place of business in this District.

3

Case 4:19-cv-01113 Document 1 Filed on 03/26/19 in TXSD Page 4 of 14

16.

Venue is proper in this judicial district pursuant to 28 U.S.C. §§ 1391, 1400

because Defendant OKT China through its majority owned subsidiary OKT USA may be found in this District. Further, Defendant OKT China is a foreign corporation and thus may be sued in any judicial district. 17.

Defendants can be found in the judicial district, or otherwise established contacts

with this judicial district sufficient enough to make the exercise of personal jurisdiction proper. 18.

Further, the Court has personal jurisdiction over OKT China because OKT China’s

infringing products are offered for sale across the United States, including in the State of Texas. For example, the accused OKT China device was sold to and installed at St. Mark’s Catholic School in Plano, TX. 19.

On information and belief, OKT China manufactured, sold, and imported its

products to the following parties in Texas: a. Pollyanna Group located at 2402 Indigo Lane, Arlington, TX 76015; b. Galaxy LED located at 5718 Fondren Rd., Houston, TX 77036; and c. MJK Lighting, Inc. located at 3026 Mockingbird Lane, Suite 136, Dallas, TX 75205 and/or 5307 E. Mockingbird Lane, Dallas, TX 75206. 20.

On information and belief, OKT China has manufactured, sold, shipped, and

imported its products to over half the United States, including Florida, Louisiana, Illinois, Massachusetts, California, New York, Texas, Minnesota, Arkansas, New Jersey, Connecticut, Colorado, Michigan, Wisconsin, North Carolina, Oregon, Georgia, Ohio, Maryland, Indiana, Iowa, Delaware, Virginia, Nevada, New Hampshire, Tennessee, South Carolina, New Mexico, Pennsylvania, Washington, Missouri, and Utah. On information, and belief, these shipments include the accused product.

Plaintiff incorporates the preceding paragraphs herein by reference.

23.

Fluxwerx is in the business of designing, manufacturing, and selling high quality

LED lighting fixtures in the United States and throughout the world. Fluxwerx is established at the forefront of LED lighting technology, with a distinctive product offering and breakthrough proprietary anidolic optics technology that offers substantial energy savings, lighting quality, and remarkable lifetime. 24.

Fluxwerx is the owner of U.S. Patent No. D747,539 (the “’539 Patent”) entitled

“Luminaire,” which issued by the United States Patent and Trademark Office on January 12, 2016. A copy of the ’539 Patent is attached as Exhibit A. 25.

The ’539 Patent is valid, enforceable, and was duly issued in full compliance with

Title 35 of the United States Code. 26.

The ’539 Patent claims the ornamental design, as shown below:

5

Case 4:19-cv-01113 Document 1 Filed on 03/26/19 in TXSD Page 6 of 14

’539 Patent, FIG. 1. 27.

Fluxwerx manufactures and sells lighting products with the design of the ’539

Patent under its “VIEW” brand (“BEAM” endcap) in several sizes, finishes, and energy/lighting configurations. 28.

In contravention to 35 U.S.C. § 271 and § 289, Defendants infringed the ’539 Patent

by making, using, selling, and/or offering to sell, or causing others to make, use, sell, and/or offer to sell LED lighting fixtures, including but not limited to the Vertical LED Linear Pendant (Model Nos. LV4-DM-XXU, LV4-DM-XXE, the “Accused Products”), which embody the design claimed in the ’539 Patent. Photographs of the Accused Products are attached hereto as Exhibit B, and reproduced below for convenience.

Case 4:19-cv-01113 Document 1 Filed on 03/26/19 in TXSD Page 9 of 14

29.

The overall appearance of Defendants’ Accused Products is substantially the same

as the design in the ’539 Patent, and/or at least a colorable imitation thereof. 30.

By way of example, both designs comprise an industrial design, including an I-

beam styled frame, and a joiner. Fluxwerx’s Design

Exhibit B at 2 (LV4-DM-XXE).

The Accused Products also contain unprotected elements of Fluxwerx’s design,

such the placement of the screws for mounting on a ceiling. 32.

The ordinary observer, seeing the Accused Products, would be deceived into

believing that it is the same as Fluxwerx’s patented design. 33.

Defendant OKT China announced that it will attend LightFair 2019, an industry

trade show occurring at Philadelphia’s Pennsylvania Convention Center from May 19-23, 2019. Defendant OKT China will display its Accused Products for sale within the United States at LightFair 2019. Exhibit C at 1 (reproduced below) (highlighting the Accused Products).

Shenzhen OKT Lighting Co. Ltd., LED Linear Pendant Lighting Fixtures available at https://www.oktlighting.com/products-pendant-linear-light.html (last visited March 18, 2019). 35.

Defendant OKT China’s marketing, advertising and other communications in

preparation for LightFair 2019 comprise an offer for sale within the meaning of the patent statute, 35 U.S.C. § 271(a), and is an infringement of the ‘539 Patent. CAUSE OF ACTION COUNT I (Infringement of U.S. Patent No. D747,539) 36.

Plaintiff incorporates the preceding paragraphs herein by reference.

37.

Defendants have infringed, currently infringe, and will continue to infringe, the

’539 Patent unless enjoined by this Court from making, using, offering for sale, importing and/or selling Fluxwerx’s patented design within the United States. 35 U.S.C. § 271(a).

11

Case 4:19-cv-01113 Document 1 Filed on 03/26/19 in TXSD Page 12 of 14

38.

On information and belief, Defendants induced and/or directed its distributors,

resellers and customers, to infringe upon the ’539 patent in violation of 35 U.S.C. § 271(b)-(c). 39.

Defendants acts of direct and indirect patent infringement are continuing and

ongoing. 40.

On information and belief, Defendants knew of Fluxwerx, Fluxwerx’s patented

product, the ’539 Patent, or were willfully blind to its existence, and Defendants knew or were willfully blind in consciously ignoring the possibility that its actions would infringe the ’539 Patent. 41.

As a direct and proximate result of Defendants’ direct and indirect infringement of

the ’539 Patent, Fluxwerx is suffering damages as well as irreparable injury for which it has no adequate remedy at law. PRAYER FOR RELIEF WHEREFORE, Plaintiff respectfully requests the Court enter judgment against Defendants: 1.

Finding that Defendants infringe U.S. Patent No. D747,539;

2.

Pursuant to 35 U.S.C. § 283, grant a preliminary and permanent injunction enjoining Defendants, their subsidiaries, affiliates, divisions, officers, agents, servants, employees, directors, partners, representatives, and all parties in active concert and/or participation with Defendants from directly or indirectly making, having made, selling, offering for sale, distributing, using, or importing into the United States products that infringe the ’539 Patent;

3.

Issue and Order prohibiting Defendants from:
