The case is BE Labs, Inc. v. CIG Shanghai Co., Ltd., No. 2:26-cv-00778 (E.D. Tex.), filed September 2, 2026 in the Marshall Division and assigned to Judge Rodney Gilstrap. BE Labs says it is a New York corporation. The complaint describes CIG Shanghai as a Chinese corporation based in Shanghai, China, and pleads venue under 28 U.S.C. 1391(c) because it is a foreign corporation. BE Labs demands a jury.

The patents

U.S. Patent 7,827,581, titled Wireless Multimedia System, issued November 2, 2010 from an application filed February 28, 2001. Claim 1, which defines its own terms for packet, communicate, and broadcast, covers a customer premises system with a wireless multimedia center that receives video, audio, and broadband data signals from one or more sources and distributes segments of them to multiple end units. The video signals are broadcast over one or more dedicated RF channels using orthogonal frequency division multiplexing with pulse widths long enough to defeat multipath, reflection, and absorption losses, and the center controls which segments of which signals go to each end unit.

U.S. Patent 9,344,183, also titled Wireless Multimedia System, issued May 17, 2016 from an application filed October 1, 2010. Claim 1 covers a multimedia device for a multi-room home or business building: a distribution box in one room that takes in an audio or video signal from a wired or wireless source, and an OFDM transceiver that broadcasts the signal one way, in multiple directions, to several end units, at least one of them in another room behind a wall, using packets wide enough to resist multipath reflection and absorption losses.

What the lawsuit is about

BE Labs alleges that CIG Shanghai directly infringes, and since service of the complaint has induced infringement of, one or more claims of each patent. The complaint identifies the accused products and exemplary claims only in claim charts attached as exhibits, which are not available, and alleges, on information and belief, that numerous other devices also infringe. It asks for a judgment that the patents are valid and infringed, damages under 35 U.S.C. 284, and a finding that the case is exceptional under 35 U.S.C. 285.

What to watch next

The docket shows a summons issued September 2, 2026. Watch for service on CIG Shanghai under the rules for foreign defendants and for its answer or Rule 12 motion. The related suit on the '581 patent is No. 2:26-cv-00779.
