Remacro Sues DewertOkin in the Eastern District of Virginia to Claim Ownership and Correct Inventorship of a Sofa Mechanism Patent.

The parties and the patent

The case is Remacro Technology Co., Ltd. v. DewertOkin Technology Group Co., Ltd., No. 1:26-cv-03710 (E.D. Va.), filed November 9, 2026. Remacro, of Suzhou, China, says it designs and makes intelligent mechanical extension devices for the furniture industry. The defendants are DewertOkin Technology Group Co., Ltd., of Jiaxing, China, which the complaint describes as the assignee and owner of record of U.S. Patent 11,564,498 B1, and the patent's four named inventors, Bin Shen, Long Li, Pengfei He, and Liming Yang. The '498 patent is titled "Intelligent Sofa Mechanical Extension Device" and issued January 31, 2023.

The allegations

The complaint alleges that the technology claimed in the '498 patent was conceived and developed within Remacro's research and development program by a Remacro engineer, and that Bin Shen, a former Remacro engineer who left in May 2019 and joined DewertOkin, had access to Remacro's confidential technical materials. It alleges that DewertOkin filed a corresponding Chinese application about eleven months later naming Bin Shen and three DewertOkin personnel as inventors, and that a Hangzhou court found in an October 30, 2023 judgment that the Chinese application belongs to Remacro. It alleges, on information and belief, that Long Li, Pengfei He, and Liming Yang made no inventive contribution, and alleges that Bin Shen made none either.

Remacro pleads in the alternative that the claimed technology was conceived by its engineer, that the invention as a whole was conceived and reduced to practice at Remacro before Bin Shen's departure, and that any contribution by Bin Shen belongs to Remacro under the law governing his employment. It invokes 35 U.S.C. 293 for jurisdiction and venue over DewertOkin as a patentee not residing in the United States.

Counts and relief

The complaint pleads three counts: Count I, declaratory judgment of equitable ownership; Count II, unjust enrichment, constructive trust and compelled assignment; and Count III, correction of inventorship under 35 U.S.C. 256. Remacro seeks a declaration and order establishing its equitable ownership of the '498 patent, a constructive trust and an order compelling assignment, and correction of inventorship to remove the named inventors it says made no inventive contribution and to add its engineer as a named inventor.
