II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,015,798
- Patent Identification: U.S. Patent No. 11,015,798, "Water-Resistant Wired Electro-Magnetic Component Capture," issued May 25, 2021.
The Invention Explained
- Problem Addressed: The patent describes a need for water-resistant holiday and decorative light strings that can be assembled without complex molding operations, which could facilitate field replacement of components and improve manufacturing yield (’798 Patent, col. 1:32-47, col. 2:3-7).
- The Patented Solution: The invention is a two-part "capture device," comprising a "base module" and a "cap module," that assembles to enclose an LED. The design aims to create water resistance through multiple mechanical seals: a primary seal is formed between the cap and base modules, while a secondary seal is created by radially compressing insulated electrical wires as they pass through channels, or "lumens," in the base module (’798 Patent, Abstract; col. 11:31-47). A key feature is the use of an injected "sealing agent" to provide water-resistant sealing inside the device (’798 Patent, col. 10:1-7).
- Technical Importance: This mechanical assembly method, combined with a sealant, presents an alternative to fully molded light string assemblies, potentially reducing manufacturing costs and complexity (’798 Patent, col. 2:27-34).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶13).
- Essential elements of claim 1 include:
- A water-resistant LED capture device with a base module and a cap module.
- An internal cavity formed by the assembled modules to receive an LED.
- A "sealing agent" disposed in the internal cavity for water-resistant sealing.
- A "first water-resistant seal" formed between the cap and base module via a "fixing structure."
- The base module defining two "lumens" for insulated conductors to pass through.
- A "second water-resistant seal" formed by "radial compression" of the insulated conductors within the lumens.
- A translucent or transparent portion of the cap module providing an optical path.
- The complaint reserves the right to assert additional claims (Compl. ¶27).
U.S. Patent No. 11,454,385
- Patent Identification: U.S. Patent No. 11,454,385, "Water-Resistant Wired Electro-Magnetic Component Capture," issued September 27, 2022.
The Invention Explained
- Problem Addressed: The patent addresses the same technical challenges as the ’798 Patent, focusing on creating robust, water-resistant outdoor lighting solutions (’385 Patent, col. 1:32-47).
- The Patented Solution: The ’385 Patent also describes a two-part housing. However, its claims focus specifically on the cooperative function of a "plurality of water-resistant seals"—one created by compression between the cap and base, and a second created by radial compression of the conductors—that together "substantially seal the internal cavity" to protect the electrical connections housed inside (’385 Patent, col. 13:26-48). Unlike the ’798 Patent's asserted claim, this patent does not require a separate "sealing agent."
- Technical Importance: This patent claims the specific functional outcome of using a combination of mechanical seals to achieve a reliably sealed internal cavity, a critical attribute for the longevity of outdoor lighting products (’385 Patent, col. 11:29-35).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶38).
- Essential elements of claim 1 include:
- A water-resistant LED capture device with a base module and a cap module.
- An internal cavity formed by the assembled modules.
- A "first water-resistant seal" created by compression between the cap and base modules.
- The base module defining at least two "lumens" for insulated conductors.
- A "second water-resistant seal" formed by "radial compression" of the conductors in the lumens.
- A "plurality of water-resistant seals," comprising the first and second seals, that "substantially seal the internal cavity" to protect the electrical connections within.
- The complaint reserves the right to assert additional claims (Compl. ¶50).
III. The Accused Instrumentality
Product Identification
- The complaint identifies the accused instrumentality as a product marketed as a "50L Light Set, 12” Lead Cord, 6” Light Spacing x 4" End to End" having features described as "Large Peripheral Visibility," "Filled & Sealed by Epoxy," and "3 Housing Layers to Secure the Lead" (the "Accused Product") (Compl. ¶15, 40).
Functionality and Market Context
- The Accused Product is alleged to be a water-resistant decorative light string (Compl. ¶16, 41). The complaint alleges, through text and annotated photographs, that each LED assembly in the Accused Product consists of a "base module" and a "cap module" that enclose an LED within an "internal cavity" (Compl. ¶17, 19, 42, 44). An annotated photograph shows the "Base module being pulled out" of the larger "cap module" to reveal the internal components (Compl. ¶17, p. 6). The complaint further alleges that the assembly is filled with a "potting compound," identified as epoxy, to provide water-resistant sealing (Compl. ¶15, 21). The complaint does not provide specific details on the product's market positioning beyond its availability for sale in the United States (Compl. ¶10).

Identified Points of Contention
- Scope Questions: For the ’798 patent, a central question may be whether the "potting compound" or "epoxy" alleged to be in the Accused Product (Compl. ¶21) meets the definition of a "sealing agent" as that term is used in the patent. The patent provides examples like "epoxies, rubber cements, or urethanes" (’798 Patent, col. 10:21-23), but the specific properties and application method of the accused compound compared to the patent's disclosure could be a point of dispute.
- Technical Questions: A key technical question for both patents is whether the assembly of the Accused Product’s components actually results in the claimed "radial compression that reduces the mean cross-sectional area of each of the two lumens" (Compl. ¶25, 48). The complaint alleges this based on visual inspection, but this may become a point of contention requiring detailed measurements and expert analysis to determine if the interaction is merely a close fit or a functionally compressive seal.
- Functional Questions: For the ’385 patent, the requirement that the plurality of seals "substantially seal the internal cavity" introduces a term of degree. This raises the evidentiary question of what level of water resistance is required to meet the "substantially seal" threshold and whether the Accused Product achieves that level of performance.
V. Key Claim Terms for Construction
The Term: "sealing agent" (’798 Patent, Claim 1)
- Context and Importance: This term appears in the asserted claim of the ’798 patent but not the ’385 patent, making its construction critical to the infringement analysis for the former. The complaint alleges that the product's epoxy/potting compound satisfies this limitation (Compl. ¶15, 21).
- Intrinsic Evidence for a Broader Interpretation: The specification provides a non-limiting list of materials, stating "various epoxies, rubber cements, or urethanes may be used" (’798 Patent, col. 10:21-23), which may support a broad construction covering a range of flowable, curable sealants.
- Intrinsic Evidence for a Narrower Interpretation: The patent describes a process where a sealant "may have been injected into an internal cavity" after the housing is assembled (’798 Patent, col. 10:4-6). A party could argue this context limits the term to liquid-applied sealants and excludes other types of seals, such as pre-formed gaskets.
The Term: "substantially seal" (’385 Patent, Claim 1)
- Context and Importance: This term of degree is central to the asserted claim of the ’385 patent. Its definition will determine the required level of water-resistance performance. Practitioners may focus on this term because the dispute could turn on whether the accused product's level of sealing is "substantial" enough.
- Intrinsic Evidence for a Broader Interpretation: The patent's background describes the goal as creating "water-resistant" light strings for outdoor use, and the specification discusses preventing "water penetration in a static configuration" (’385 Patent, col. 1:32-34; col. 2:37-38). This may support a practical standard of water resistance rather than a hermetic seal.
- Intrinsic Evidence for a Narrower Interpretation: The claim requires that the seals "substantially seal the internal cavity such that electrical connections...are sealed within the internal cavity" (’385 Patent, col. 16:29-33). This linkage could support an argument for a higher standard of sealing, one sufficient to ensure no moisture reaches the vital electrical contacts.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that the Defendant induces infringement by "instructing and encouraging its customers, purchasers, users, vendors, partners, and manufacturers" and through advertising and promotion (Compl. ¶33, 56).
- Willful Infringement: The complaint alleges that the Defendant "knew or was willfully blind" to the fact that it was inducing infringement (Compl. ¶32, 55). The basis for this knowledge is alleged to be post-suit, arising "at least the time it was served with the Complaint in this lawsuit" (Compl. ¶31, 54).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim construction: Can the term "sealing agent" in the ’798 patent be construed to cover the specific epoxy compound used in the accused product? Furthermore, what standard of performance does the term "substantially seal" in the ’385 patent require, and can the plaintiff provide evidence that the accused product meets it?
- A key evidentiary question will be one of technical function: Does the physical assembly of the accused product's base and conductors generate the "radial compression that reduces the mean cross-sectional area" of the wire lumens as required by both asserted claims, or is the interaction a non-compressive, close-tolerance fit that falls outside the claim scope?
- A central procedural question will be the development of evidence for willfulness: Since the complaint pleads knowledge for willfulness and inducement only from the date of service, the plaintiff’s ability to obtain enhanced damages will likely depend on whether it can uncover evidence of pre-suit knowledge during discovery.
