Enerlites Inc v. Century Products Inc
Key Events
Complaint
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Enerlites, Inc. & Top Greener, Inc. (California)
- Defendant: Century Products, Inc. & Wei Hu (California)
- Plaintiff’s Counsel: Law Offices of Fei Pang
- Case Identification: 8:18-cv-00839, C.D. Cal., 05/14/2018
- Venue Allegations: Venue is based on the Defendants’ residence and principal place of business being located within the Central District of California, as well as allegations that a substantial part of the events giving rise to the claims occurred in the district.
- Core Dispute: Plaintiffs allege that Defendants’ in-wall timer products infringe a design patent covering the ornamental appearance of Plaintiffs' digital timer product.
- Technical Context: The technology at issue is digital in-wall electrical timers, a common product category for energy management and lighting control in residential and commercial settings.
- Key Procedural History: The complaint alleges that Plaintiffs sent Defendants a "Cease and Desist" letter notifying them of the asserted intellectual property rights approximately nine months prior to filing the lawsuit. This event is cited to support the allegation of willful infringement.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. D575,646 - "DIGITAL IN-WALL TIMER"
- Patent Identification: U.S. Design Patent No. D575,646, titled "DIGITAL IN-WALL TIMER", issued August 26, 2008.
The Invention Explained
- Problem Addressed: Design patents do not solve technical problems in the manner of utility patents; rather, they protect the novel, non-functional, ornamental appearance of an article of manufacture. The objective is to create a visually distinctive product identity in the market for electrical wall fixtures (D’646 Patent, Claim).
- The Patented Solution: The patent protects the specific visual appearance of an in-wall timer. The design consists of a rectangular faceplate with a central timer unit. The claimed ornamental features, shown in solid lines, include a rectangular digital display at the top of the unit, a hinged rectangular door below the display, and an arrangement of multiple rectangular buttons below the door (D’646 Patent, FIGURE). The description clarifies that the single FIGURE depicts the new design and that broken lines represent unclaimed environmental subject matter (D’646 Patent, Description).
- Technical Importance: The complaint alleges that the product embodying the patented design has achieved substantial success and market recognition, suggesting the ornamental design itself may serve as a source of commercial goodwill (Compl. ¶¶ 6-7, 17).
Key Claims at a Glance
- The patent asserts a single claim: "The ornamental design for a digital in-wall timer, as shown and described" (D’646 Patent, Claim).
- As a design patent, the claim's scope is defined by the visual representation in the patent's drawing, not by a list of textual elements.
III. The Accused Instrumentality
Product Identification
- The complaint accuses "one or more lighting apparatuses" manufactured, used, or sold by Defendants (Compl. ¶ 18). A photograph of a representative "INFRINGING PRODUCT" is provided in the complaint (Compl. p. 8).
Functionality and Market Context
- The accused instrumentalities are described as digital in-wall timers that compete with Plaintiffs' products (Compl. ¶¶ 18-19). The complaint alleges that Defendants' products are sold through channels including a California-based website to California consumers (Compl. ¶ 12). Plaintiffs position the alleged infringement as an attempt by Defendants to "take a 'free ride' on their goodwill, reputation and fame" (Compl. ¶ 19). The complaint includes a side-by-side comparison photograph of the "PATENTED PRODUCT" and the "INFRINGING PRODUCT" to illustrate the alleged similarity (Compl. p. 8).
IV. Analysis of Infringement Allegations
D575,646 Infringement Allegations
| Claim Element (from Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| The ornamental design for a digital in-wall timer, as shown and described. | The complaint alleges that the accused product incorporates a design that is "highly similar (if not virtually identical)" to the patented design. A provided photograph shows an accused product with a comparable overall rectangular form factor, a top-positioned digital display, a centrally-located hinged door, and a similar arrangement of buttons. | ¶25, p. 8 | D’646 Patent, FIGURE |
- Identified Points of Contention:
- Scope Questions: A central question will be whether the overall visual impression of the accused product is "substantially the same" as the claimed design in the eye of an "ordinary observer." The analysis will require comparing the designs as a whole, rather than focusing on dissected features.
- Technical Questions: A potential issue for the court is whether the similarities between the two designs are dictated by functional necessity rather than ornamental choice. The question may be raised whether the general arrangement of a screen, door, and buttons on a rectangular faceplate is a functional configuration common to such devices, which could limit the scope of what is protectable under the design patent.
V. Key Claim Terms for Construction
In design patent cases, the "claim" is the drawing, and traditional construction of textual terms is not the primary focus. Instead, the court describes the visual scope of the claimed design.
- The "Term": The overall ornamental visual impression of the timer.
- Context and Importance: The entire infringement analysis will depend on the scope of the patented design as construed by the court. Practitioners may focus on this issue because the outcome of the "ordinary observer" test is contingent on a proper understanding of what visual features constitute the protected design.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party could argue the claim covers the overall aesthetic combination and arrangement of the key features—a top-mounted screen, a central hinged door, and a lower button field—within a rectangular timer body. The argument would be that the design's gestalt, not just the precise contours of each element, is what is protected (D’646 Patent, FIGURE).
- Evidence for a Narrower Interpretation: A party could argue the claim is limited to the specific proportions, shapes, and layout of the elements as depicted in solid lines in the drawing. The patent's description explicitly notes that broken lines (the outer wall plate) are unclaimed environment, which by negative implication suggests the specific visual details shown in solid lines are integral to the claim's scope (D’646 Patent, FIGURE, Description).
VI. Other Allegations
- Indirect Infringement: The complaint does not plead specific counts for indirect infringement (inducement or contributory infringement) and does not provide sufficient detail for analysis of these claims. The primary allegation is for direct infringement under 35 U.S.C. § 271(a) (Compl. ¶ 19).
- Willful Infringement: The complaint alleges that Defendants' infringement was "willful, wanton, and deliberate" (Compl. ¶ 27). This allegation is supported by the factual assertion that Plaintiffs sent Defendants a "Cease and Desist" letter on August 17, 2017, putting Defendants on notice of the patent, and that Defendants allegedly continued their infringing activities thereafter (Compl. ¶ 22).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of visual similarity: Under the "ordinary observer" test, is the ornamental design of the accused timer substantially the same as the design claimed in the D’646 patent, such that an ordinary purchaser would be deceived? This is a factual question that will likely require a side-by-side comparison in view of the prior art.
- A key legal and factual question will be one of functionality: To what extent are the shared visual features between the patented design and the accused product dictated by their function as in-wall timers? The court’s determination of which design elements are ornamental versus functional will be critical in defining the enforceable scope of the patent.
- A central evidentiary question for damages will be willfulness: Assuming infringement is found, did the Defendants' conduct rise to the level of willful infringement? The analysis will likely focus on the notice provided by the August 2017 cease-and-desist letter and the nature of Defendants' actions after receiving it.
