Strongest Home Seeks a Declaratory Judgment That a Doorstop Design Patent Is Invalid After Amazon Pulls Six Listings.

The parties and the court

The case is Strongest Home, Inc. v. Bojian Wu, No. 1:26-cv-03257 (E.D. Va., Alexandria Division), filed October 2, 2026. The docket shows it assigned to District Judge Anthony J. Trenga and Magistrate Judge Lindsey R. Vaala. The complaint describes Strongest Home as a corporation with a business address in Sheridan, Wyoming, that sells adjustable doorstops through Amazon. It describes Wu as an individual whose application data sheet identifies a residence in Nanchang, China, and alleges, on information and belief, that he owns the patent because its face identifies him as inventor and applicant and no transfer has been located. Jurisdiction and venue are pleaded in part under 35 U.S.C. 293, on the allegation, made on information and belief, that Wu is a patentee not residing in the United States who has not designated a U.S. resident for service.

The patent and its prosecution

U.S. Design Patent D1,138,723 issued August 4, 2026 from Application No. 29/999,324, filed April 16, 2025, and claims the ornamental design for a door stopper. The complaint alleges that the examiner's February 20, 2026 final office action rejected replacement line drawings as new matter not supported by the original photographs, and that Wu's March 11, 2026 reply attributed the differences to photographic perspective or representation format rather than substantive changes, after which the patent issued on the line drawings.

The Amazon report

The complaint alleges that Wu reported the six accused listings to Amazon as infringing the '723 patent, that Amazon's notice dated September 17, 2026 identified Wu as the rights owner and deactivated the listings, and that monthly sales of the six products fell from an average of $36,486 in June through August 2026 to $910 for the rest of September. It says Strongest Home asked Wu to retract the report on September 26 and 29, and that on September 30 he replied that he would not.

The counts

Count I seeks a declaratory judgment that the design claim is invalid as anticipated under 35 U.S.C. 102 by a Chinese design patent granted and published on May 13, 2022, and, independently, by a doorstop the complaint says was publicly offered on Amazon no later than March 24, 2024, or as obvious under 35 U.S.C. 103 over those references and others. Count II, pleaded in the alternative, seeks a declaratory judgment that the six products do not infringe because, in light of crowded prior designs, they create a different overall impression for an ordinary observer, pointing to a wider projecting upper panel, a diagonal separation between the members, and an exposed full-width hinge barrel.

Relief sought

Strongest Home asks for declarations of invalidity and, in the alternative, noninfringement; a temporary, preliminary, and permanent order directing Wu to withdraw the Amazon complaint as to the six products; an injunction barring further reports asserting the patent against its products; and costs and, where warranted, attorneys' fees under 35 U.S.C. 285. It demands a jury.

What to watch next

On October 2, 2026 Strongest Home filed an emergency motion for a temporary restraining order, and the court granted its motion for court-directed service, ordering service under 35 U.S.C. 293 and Rule 4(f)(3) by email to the address on the Amazon notice. An affidavit filed October 5 says the defendant was served on October 2. Watch for a ruling on the TRO motion and for Wu's response.
