Lider Electric Inc v. Socket Solutions LLC
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Lider Electric Inc. (California)
- Defendant: Socket Solutions, LLC (Texas)
- Plaintiff’s Counsel: Foley & Lardner LLP
- Case Identification: 8:23-cv-01054, C.D. Cal., 06/14/2023
- Venue Allegations: Plaintiff alleges venue is proper because Defendant purposefully targeted Plaintiff, a California company, in the district through patent enforcement actions on Amazon, derives substantial revenue from sales in the district, and the alleged harm to Plaintiff is felt within the district.
- Core Dispute: Plaintiff seeks a declaratory judgment that its "Outlet Extender" products do not infringe Defendant's patent covering a low-profile, wall-hugging electrical outlet cover, and that the patent is invalid.
- Technical Context: The technology concerns aesthetic and functional electrical outlet covers that allow an extension cord to run from the outlet while sitting nearly flush against the wall, enabling furniture placement and concealing the outlet.
- Key Procedural History: The dispute arises from pre-suit enforcement actions. Defendant Socket Solutions allegedly sent multiple takedown requests to Amazon, accusing Plaintiff Lider’s products of infringement. After an initial takedown and reinstatement, a second takedown request led to the removal of Lider's product listings, prompting Lider to file this declaratory judgment action to resolve the controversy.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,509,080 - “Functional Indoor Electrical Wall Outlet Cover”
The Invention Explained
- Problem Addressed: The patent’s background section notes that typical electrical plugs extend "several inches from the wall," which prevents furniture from being positioned flush against it and is "generally unattractive" (’080 Patent, col. 1:20-24). Standard outlets are also described as a potential safety hazard for children (’080 Patent, col. 1:31-33).
- The Patented Solution: The invention is a thin cover that completely conceals a wall outlet while allowing its continued use (’080 Patent, Abstract). It achieves a low profile through a functional plug with electrical pins that are "bent at approximately ninety degree angle," which connects to an extension cord, allowing the cover to sit nearly flush with the wall (’080 Patent, col. 2:15-19; Fig. 5). This design hides the outlet and minimizes the distance the plug assembly protrudes from the wall.
- Technical Importance: The invention combines the aesthetic and safety features of an outlet cover with the functionality of an extension cord, specifically addressing the physical obstruction caused by conventional plug designs (’080 Patent, col. 2:50-65).
Key Claims at a Glance
- The complaint seeks a declaratory judgment of non-infringement as to all claims of the ’080 Patent, with specific non-infringement arguments made concerning independent claims 1, 19, 22 and dependent claim 16 (Compl. ¶¶ 73, 75-79).
- Independent Claim 1, a representative claim, requires:
- An apparatus for hiding a standard indoor electrical wall outlet.
- A cover comprising a frontplate and a backplate.
- The backplate has at least one set of electrical prongs to engage a receptacle of the wall outlet.
- An electrical cord extends from the cover.
- The cord’s proximal end has a hot pin and a neutral pin connected to the prongs.
- A key limitation requires "the hot pin and the neutral pin are positioned at approximately right angles to the backplate."
- The cord’s distal end has at least one receptacle.
- The complaint seeks a declaration that all claims of the ’080 Patent are not infringed (Compl. ¶80).
III. The Accused Instrumentality
Product Identification
- The accused product is the "Lider Outlet Extender" (Compl. ¶2).
Functionality and Market Context
- The Lider Outlet Extender is an electrical device with a flat plug that connects to a wall outlet and an extension cord that terminates in a power strip with multiple receptacles (Compl. ¶2, p. 2). The complaint provides a photograph of the accused "Lider Product," showing a flat wall plug connected by a white cord to a three-outlet power strip (Compl. p. 2). The products are sold "essentially entirely on Amazon," which is alleged to be Lider's primary sales platform (Compl. ¶¶ 3, 16). The complaint alleges that the accused products compete directly with Defendant's "Sleek Socket" product, which is purported to be a commercial embodiment of the ’080 Patent (Compl. ¶27).
IV. Analysis of Non-Infringement Allegations
’080 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Non-Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| b. an electrical cord extending from the backplate... wherein the hot pin and the neutral pin are positioned at approximately right angles to the backplate | The "pins" of the Lider Products are alleged to "extend along the same direction along which the 'prongs' of the Lider Products also extend," and "do not form right angles to the backplate and are not 'bent' to conserve space." | ¶75 | col. 8:39-41 |
Identified Points of Contention
- Scope Questions: A central issue is the interpretation of the claim limitation "positioned at approximately right angles to the backplate." The dispute will question whether this language requires a specific physical structure, such as the distinctly bent pins illustrated in the patent's Figure 5, or if it can be read more broadly to cover any low-profile plug design where the cord exits parallel to the wall face.
- Technical Questions: The complaint asserts that the pins in the Lider product are not "bent" and do not form "right angles" (Compl. ¶75). A key factual question will be what the internal construction of the accused product's plug actually is and whether that construction falls within the court's ultimate construction of the "right angles" limitation.
V. Key Claim Terms for Construction
The Term
- "positioned at approximately right angles to the backplate"
Context and Importance
- This term is the primary basis for the plaintiff's non-infringement argument for claim 1. Its construction will be critical in determining whether the Lider Outlet Extender's plug design meets this limitation. Practitioners may focus on this term because its interpretation—whether it requires a specific bent-pin structure or allows for other functionally similar low-profile designs—appears to be dispositive of the infringement question.
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: A party arguing for a broader construction might emphasize the word "approximately," suggesting that a perfect 90-degree bend is not required. They could also argue that the term should be interpreted functionally to cover any design that achieves the patent's stated goal of minimizing the distance the assembly protrudes from the wall.
- Evidence for a Narrower Interpretation: A party arguing for a narrower construction will likely point to the patent’s specification, which repeatedly describes the pins as being "bent at approximately ninety degree angle" (’080 Patent, col. 2:15-17), and to Figure 5, which explicitly illustrates this bent-pin configuration. The abstract also links the cover's low-profile function directly to "electrical connection pins that are bent at a [sic] angle" (’080 Patent, Abstract).
VI. Other Allegations
Invalidity
- The complaint includes a second count seeking a declaratory judgment of invalidity for all claims (1-24) of the ’080 Patent (Compl. ¶¶ 82-87).
- Obviousness: It alleges the patent is an obvious variation of a "commonplace flat-head extension cord plug wherein the flat head is wide enough to cover the wall outlet" (Compl. ¶84).
- Indefiniteness: It alleges claims 1, 19, and 22 are invalid as indefinite under 35 U.S.C. § 112 because they recite positioning wires "in such manner as to minimize distance between the front plate and the backplate," which is argued to be a subjective, relative term without an objective standard (Compl. ¶85).
Exceptional Case
- The complaint does not allege willful infringement but does seek a finding that the case is "exceptional" and an award of attorneys' fees, based on Defendant's alleged conduct in pursuing Amazon takedown requests (Compl. p. 16).
VII. Analyst’s Conclusion: Key Questions for the Case
This declaratory judgment action appears to center on three fundamental questions for the court:
A core issue will be one of claim construction: How narrowly will the court define the limitation "positioned at approximately right angles to the backplate"? Will it be limited to the "bent" pin structure explicitly described and depicted in the patent, or can it encompass other plug designs that achieve a similar low-profile result?
A secondary issue will be one of validity: Is the claimed invention merely an obvious combination of a known flat-head extension cord with a decorative cover, as the complaint alleges? Further, is the phrase "minimize distance" sufficiently clear to inform a person of ordinary skill in the art of the scope of the claim, or is it fatally indefinite?
A final procedural question will be one of enforcement conduct: Did the defendant's use of Amazon's patent takedown process constitute conduct that would make this an "exceptional case" warranting an award of attorneys' fees, regardless of the outcome on the merits of infringement and validity?
