Complaint

I. Executive Summary and Procedural Information

  • Parties & Counsel:
  • Case Identification: 3:23-cv-00074, E.D. Va., 01/26/2023
  • Venue Allegations: Venue is alleged to be proper in the Eastern District of Virginia because a substantial part of the events, specifically the filing of allegedly "sham assignments" with the U.S. Patent and Trademark Office, occurred in the district. The complaint also asserts "in rem" jurisdiction over the patents themselves as property located within the district.
  • Core Dispute: Plaintiff seeks a declaratory judgment that its monitor and television stands do not infringe two of Defendants' design patents, and further that the patents are invalid and unenforceable due to alleged fraud, inequitable conduct, and derivation of the designs from Plaintiff's own pre-existing products.
  • Technical Context: The dispute concerns the ornamental designs of consumer electronic stands, specifically desktop monitor risers and tabletop television stands.
  • Key Procedural History: The complaint references a prior, related lawsuit (Case No. 1:21-cv-00471) filed by the same Plaintiff against Defendant Lyu in the same court. Plaintiff alleges that after it filed an amended complaint in the prior action, Defendant Lyu engaged in a "sham assignment" of the patents to a controlled entity in an attempt to divest the court of jurisdiction, which prompted the filing of the current lawsuit against the new, purported assignees.

  • The essential visual elements comprising the claimed design are:
    • A flat, rectangular base
    • A central vertical support column
    • A rear mounting bracket featuring two vertical arms with elongated slots and horizontal cross-members

III. The Accused Instrumentality

  • Product Identification: Plaintiff's "adjustable monitor riser stand (item model number STT003)" and "television stand (item model number TVDVD-01)" (Compl. ¶¶ 15, 19).
  • Functionality and Market Context: The complaint describes the STT003 as a monitor stand with "rounded and beveled edges and a vented platform" (Compl. ¶ 15). The TVDVD-01 is described as a "Universal TV Stand, Table Top TV Stand for 32 to 47 inch Flat TV" (Compl. ¶ 19). The complaint alleges that these products are sold through Plaintiff's Amazon.com storefront (Compl. ¶ 12). An image from an Amazon product listing for the STT003 monitor stand is included in the complaint (Compl. p. 5).

IV. Analysis of Infringement Allegations

As this is a complaint for a declaratory judgment of non-infringement and invalidity, the analysis focuses on the Plaintiff’s allegations that its products do not infringe and, more centrally, that the patents are invalid because the Plaintiff’s own products constitute invalidating prior art. The complaint alleges that the patented designs are "substantially similar" to its products, which were on sale before the patents' filing dates (Compl. ¶¶ 23-26, 28).

D910,645 Infringement Allegations

Claim Element (The ornamental design for a table top monitor stand) Alleged Substantially Similar Prior Art Feature (Plaintiff's STT003) Complaint Citation Patent Citation
The overall ornamental design as shown in the patent figures. Plaintiff's STT003 monitor stand, which is alleged to have a "substantially similar" design with "rounded beveled edges and a vented platform." A drawing from the patent is provided to illustrate the design. ¶24 FIG. 1, 6

D853,403 Infringement Allegations

Claim Element (The ornamental design for a support for television apparatus) Alleged Substantially Similar Prior Art Feature (Plaintiff's TVDVD-01) Complaint Citation Patent Citation
The overall ornamental design as shown in the patent figures, particularly the front view. Plaintiff's TVDVD-01 television stand. The complaint provides a side-by-side visual comparison of the patent's FIG. 3 and a photograph of the Plaintiff's product, alleging they are "substantially similar." ¶26, p. 8 FIG. 3
  • Identified Points of Contention:
    • Validity Question: A primary issue is whether Plaintiff's documented sales of its monitor and television stands occurred more than one year before the respective patent application filing dates (Compl. ¶¶ 23, 25). If so, and if the designs are found to be substantially the same, this could render the patents invalid under the on-sale bar of 35 U.S.C. § 102.
    • Inventorship/Derivation Question: The complaint raises the question of whether Defendant Lyu is the true inventor. It alleges that Lyu accessed the designs through a business relationship with the factory manufacturing Plaintiff's products and filed for patent protection on designs he did not invent (Compl. ¶¶ 13-14, 27). This raises a fundamental challenge to the patents' validity based on derivation.
    • Design Similarity Question: The core of the invalidity argument rests on whether an ordinary observer would find the designs of Plaintiff’s products to be substantially the same as the designs claimed in the patents. The side-by-side comparison for the '403 patent is presented as direct evidence for this contention (Compl. p. 8).

V. Key Claim Terms for Construction

In design patent cases, construction focuses on the overall visual appearance of the design as a whole, rather than the definition of specific words.

  • The Term: The overall ornamental design for a "table top monitor stand" ('645 Patent) and "support for television apparatus" ('403 Patent).
  • Context and Importance: The central analysis will involve a visual comparison between the patented designs and Plaintiff’s products (as alleged prior art). The court's interpretation of the scope of the claimed ornamental designs—what features are ornamental versus functional—will be dispositive for the invalidity analysis. Practitioners may focus on whether features like the "vented platform" of the monitor stand (Compl. ¶ 15) or the VESA-style mounting slots of the TV stand are primarily functional, which could limit the scope of the claimed ornamental design.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claimed design is defined by all elements shown in solid lines in the patent figures ('645 Patent, FIG. 1-7; '403 Patent, FIG. 1-8). The claim covers the overall visual impression created by these features in combination, not just isolated elements.
    • Evidence for a Narrower Interpretation: The dashed lines in the '403 patent explicitly disclaim those portions of the television stand, limiting the scope of the claimed design ('403 Patent, Description). Furthermore, if features are found to be dictated by their function (e.g., the hole pattern for ventilation on the monitor stand or the slot shape for adjustability on the TV stand), a court may accord them less weight in the "ordinary observer" analysis, effectively narrowing the scope of the protectable ornamental design.

VI. Other Allegations

  • Indirect Infringement: The complaint seeks a declaratory judgment of non-infringement both "directly or indirectly" (Compl. ¶¶ 58, 63). However, it does not plead specific facts related to inducement or contributory infringement theories.
  • Willful Infringement: The complaint does not allege willful infringement by an infringer. Instead, it alleges "intentional, malicious, and fraudulent conduct" by the Defendants in procuring and asserting the patents (Compl. ¶ 72). The basis for this allegation, which supports a claim for an exceptional case, includes the alleged concealment of Plaintiff's prior art sales from the USPTO (constituting inequitable conduct) and the use of infringement claims to have Plaintiff's entire Amazon storefront removed (Compl. ¶¶ 21-22, 29-30).

VII. Analyst’s Conclusion: Key Questions for the Case

  • A foundational question will be one of validity based on prior art and inventorship: Does the evidence establish that Plaintiff's products were publicly sold more than one year prior to the patents' filing dates, and did the named inventor derive the designs from Plaintiff's pre-existing products? The answer will likely determine the validity of both patents-in-suit.
  • A critical threshold issue will be one of patent ownership and jurisdiction: Was the post-litigation assignment of the patents-in-suit a legitimate transfer, or was it a "sham assignment" intended to improperly divest the court of jurisdiction, as the complaint alleges? The court's resolution of this issue will impact which parties are proper to the suit.
  • The case will also turn on a question of visual similarity: From the perspective of an ordinary observer, are the ornamental designs of Plaintiff’s prior-art products "substantially the same" as the designs claimed in the '645 and '403 patents? The side-by-side comparison evidence presented in the complaint suggests this will be a central point of visual analysis for the court.
