ORIGINAL COMPLAINT FOR PATENT 

INFRINGEMENT

Plaintiff WSOU Investments, LLC d/b/a Brazos Licensing and Development (“Brazos” 

or “Plaintiff”), by and through its attorneys, files this Complaint for Patent Infringement against 

Defendants ZTE Corporation, ZTE (USA), Inc. and ZTE (TX), Inc. (collectively “ZTE” or 

“Defendants”) and alleges:

NATURE OF THE ACTION

1. This is a civil action for patent infringement arising under the Patent Laws of the

Delaware, with its principal place of business at 605 Austin Ave, Ste 6, Waco, TX 76701.

3. On information and belief, Defendant Zhongxing Telecommunications

4. On information and belief, Defendant ZTE (USA) Inc. is a New Jersey 

corporation that does business in Texas, directly or through intermediaries, with a principal place 

of business in business in Richardson, Texas.

5. On information and belief, Defendant ZTE (TX) Inc. is a Texas corporation that 

does business in Texas, directly or through intermediaries, with a principal place of business in 

business in Austin, Texas.

6. All of the Defendants operate under and identify with the trade name “ZTE.” 

Each of the Defendants may be referred to individually as a “ZTE Defendant” and, collectively, 

Defendants may be referred to below as “ZTE” or as the “ZTE Defendants.”

JURISDICTION AND VENUE

7. This is an action for patent infringement which arises under the Patent Laws of 

the United States, in particular, 35 U.S.C. §§271, 281, 284, and 285.

8. This Court has jurisdiction over the subject matter of this action under 28 U.S.C.

§§ 1331 and 1338(a).

9. This Court has specific and general personal jurisdiction over each ZTE

Defendant pursuant to due process and/or the Texas Long Arm Statute, because each ZTE

Defendant has committed acts giving rise to this action within Texas and within this judicial 

district. The Court’s exercise of jurisdiction over each ZTE Defendant would not offend 

traditional notions of fair play and substantial justice because ZTE has established minimum 

contacts with the forum. For example, on information and belief, ZTE Defendants have 

committed acts of infringement in this judicial district, by among other things, selling and 

offering for sale products that infringe the asserted patent, directly or through intermediaries, as 

alleged herein.

10. Venue in the Western District of Texas is proper pursuant to 28 U.S.C. §§1391

and/or 1400(b). The ZTE Defendants have committed acts of infringement and have places of 

businesses in this District and/or are foreign entities for purpose of §1391. As non-limiting 

examples, ZTE (TX) has maintained a place of business at 7000 N MO-PAC EXPRESSWAY 

200 AUSTIN, TX 7873; and, ZTE (USA) has maintained a place of business at 6500 River Place 

Blvd., Austin, TX 78730. ZTE Corporation also describes a “research-and-development center 

in Austin, Texas.”1

U.S. PATENT NO. 8,730,905

11. Brazos re-alleges and incorporates by reference the preceding paragraphs of this

Complaint.

12. On May 20, 2014, the United States Patent and Trademark Office duly and legally

issued U.S. Patent No. 8,730,905 (“the ’905 Patent”), entitled “TRANSMISSION RESOURCE 

RESERVATION SCHEME.” A true and correct copy of the ’905 Patent is attached as Exhibit 

A to this Complaint.

13. Brazos is the owner of all rights, title, and interest in and to the ’905 Patent,

including the right to assert all causes of action arising under the ’905 Patent and the right to any 

remedies for the infringement of the ’905 Patent.

14. ZTE makes, uses, sells, offers for sale, imports, and/or distributes, in the United

States, communication devices, including hotspots, routers, switches, gateways, and phones

contributed to the infringement of the ’905 Patent by having others sell, offer for sale, or use the 

Accused Products throughout the United States, including within this judicial district, with

knowledge that the Accused Products infringe the ’905 Patent. The Accused Products are 

especially made or adapted for infringing the ’905 Patent and have no substantial non-infringing 

use. For example, in view of the preceding paragraphs, the Accused Products contain 

functionality which is material to at least one claim of the ’905 Patent.
