II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,571,104 - “Portable Lamp and Manufacturing Method Thereof”
- Patent Identification: U.S. Patent No. 10,571,104, “Portable Lamp and Manufacturing Method Thereof,” issued February 25, 2020. (Compl. ¶8).
The Invention Explained
- Problem Addressed: The patent’s background section describes conventional folding portable lamps as having poor stability when unfolded and limited adaptability because the direction of illumination is constrained by the physical orientation of the lamp bodies (’104 Patent, col. 2:30-55).
- The Patented Solution: The invention discloses a portable lamp where one or more lighting devices are mounted on a central rotation shaft, which is itself connected to at least one handle body. This construction allows the lighting device(s) to be rotated independently of the handle(s), which can be positioned to form a stable base (’104 Patent, Abstract; col. 9:48-60). This design decouples the lighting angle from the base configuration.
- Technical Importance: The described solution aims to provide enhanced flexibility and stability for portable work lights by allowing users to adjust illumination direction without compromising the lamp’s physical support (’104 Patent, col. 3:5-9).
Key Claims at a Glance
- The complaint asserts independent Claim 1 and dependent Claims 2-5 (Compl. ¶¶14, 16).
- Essential elements of independent Claim 1 include:
- A portable lamp, comprising:
- a handle means comprising at least one handle body having two end portions and a turning space defined between said two end portions;
- and at least one lighting device which is rotatably mounted between said two end portions of said at least one handle body
- and selectively arranged to be maintained within said turning space of said at least one handle body as a folded state
- and to rotate with respect to said at least one handle body to define an included angle between said at least one lighting device and said at least one handle body as an unfolded state.
- The complaint reserves the right to assert additional claims (Compl. ¶16).

IV. Analysis of Infringement Allegations
The complaint references claim charts attached as exhibits that were not provided with the filed document. The following summary is based on the narrative allegations in the complaint.
U.S. Patent No. 10,571,104 Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a handle means comprising at least one handle body having two end portions and a turning space defined between said two end portions | The accused products are alleged to possess a handle structure with end portions and an internal turning space. | ¶15; ¶17 | col. 10:49-54 |
| and at least one lighting device which is rotatably mounted between said two end portions of said at least one handle body | The accused products are alleged to feature a lighting device that is rotatably mounted between the end portions of the handle. | ¶15; ¶17 | col. 9:48-54 |
| and selectively arranged to be maintained within said turning space of said at least one handle body as a folded state | The accused products' lighting device is allegedly capable of being positioned and maintained within the handle's turning space in a folded configuration. | ¶15; ¶17 | col. 10:27-31 |
| and to rotate with respect to said at least one handle body to define an included angle between said at least one lighting device and said at least one handle body as an unfolded state | The accused products' lighting device is allegedly able to rotate relative to the handle to form various angles when in an unfolded state. | ¶15; ¶17 | col. 9:56-60 |
Identified Points of Contention
- Viability of Claim: A threshold issue is the legal status of the infringement allegation for the ’104 Patent, as the asserted independent Claim 1 was canceled in a post-filing ex parte reexamination. This action may render the infringement claim moot.
- Scope Questions: Assuming the claim were still valid, a key dispute would concern the construction of "handle means." As a means-plus-function term, its scope is tied to the specific structures disclosed in the specification (e.g., the "adjusting device 30"). The analysis will question whether the accused products contain a structure that is identical or equivalent to that disclosed structure.
- Technical Questions: The complaint does not provide sufficient detail for analysis of the specific mechanism by which the accused products' lighting devices are "rotatably mounted." Evidence will be needed to determine if the accused mechanism performs the claimed function in substantially the same way to achieve the same result as the structure disclosed in the patent.
V. Key Claim Terms for Construction
The Term: "handle means"
- Context and Importance: This term, appearing in the preamble of Claim 1, is drafted in means-plus-function format under 35 U.S.C. § 112(f). Its construction is critical because infringement requires showing the accused products have a structure that is identical or equivalent to the specific "corresponding structure" disclosed in the patent specification for performing the claimed function of acting as a handle.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: Parties seeking a broader scope may argue the "means" simply refers to the general structure of the "handle body 20," comprising a "handle element 21" and two "extending arms 22," which create a space for handling and mounting (’104 Patent, col. 10:49-54).
- Evidence for a Narrower Interpretation: Parties seeking a narrower scope may argue that the "corresponding structure" for the "handle means" must include the "adjusting device 30" (’104 Patent, col. 9:48-54), including the specific "engaging member 321" and "fastening member 322" mechanism, because this structure is essential to the claimed function of enabling rotatable mounting (’104 Patent, col. 12:8-20).
VI. Other Allegations
Indirect Infringement
The complaint's prayer for relief seeks an injunction against inducing and contributing to infringement for all three patents (Compl. pp. 8-9, ¶¶ 2, 6, 10). However, the complaint lacks specific factual allegations in the body to support the required elements of knowledge and intent for such claims.
Willful Infringement
The complaint alleges willful infringement based on pre-suit knowledge (Compl. p. 9, ¶13(5)). The stated basis is that Plaintiff sent notice letters to Defendant on July 21, 2022, and August 15, 2022, but Defendant allegedly continued to market the accused products thereafter (Compl. ¶¶11-12).
VII. Analyst’s Conclusion: Key Questions for the Case
- A dispositive threshold question will be one of claim viability: can the infringement count for the '104 patent proceed, given that its only asserted independent claim was canceled during an ex parte reexamination that concluded after the complaint was filed?
- A core issue for the '104 patent, should the claim survive, will be one of structural equivalence: does the infringement analysis of the term "handle means" require finding a structure in the accused products that is equivalent to the specific multi-part "adjusting device" disclosed in the patent, or can it be met by any handle structure that permits rotation?
- For the '743 and '036 design patents, the case will turn on an issue of ornamental identity: would an ordinary observer, familiar with the prior art of work lights, be deceived into believing that the accused Bell & Howell products are the same as the specific ornamental designs claimed in the patents?
