II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 6,309,085 - Lamp Support for Emergency Light Fixture (Issued Oct. 30, 2001)

The Invention Explained

  • Problem Addressed: The patent notes that many existing lamp supports for emergency lights do not solve the problem of "providing adequate positioning of an ambient and/or directed light source in an emergency situation" (’085 Patent, col. 4:50-54).
  • The Patented Solution: The invention is a lamp support that includes a base, a pair of stems extending from the base, and a housing for a light source that is "rotatably attached between the first stem and the second stem" ('085 Patent, col. 6:49-50). This structure, as detailed in the specification, enables the housing to rotate 360 degrees on an axis created by the stems, allowing a user to precisely position the light ('085 Patent, Abstract; col. 6:49-52).
  • Technical Importance: The design aims to provide "superior positioning capability" for emergency lighting without the need for complex fasteners, which could simplify installation and adjustment ('085 Patent, col. 4:56-58).

Key Claims at a Glance

  • The complaint asserts independent claim 10 (Compl. ¶26).
  • Essential elements of Claim 10:
    • a housing adapted for supporting a light source; and
    • a mounting structure rotatably connected to the housing to permit rotation of the housing about an axis determined by the mounting structure.

U.S. Patent No. 6,606,808 - Exit Sign with Rotatable Lighting Heads (Issued Aug. 19, 2003)

The Invention Explained

  • Problem Addressed: The patent's background describes prior art emergency lighting heads on exit signs as being either fixed or having limited adjustment capabilities that often require the "loosening and tightening of mechanical fasteners," which can be "time consuming or limited in range" (’808 Patent, col. 2:43-48).
  • The Patented Solution: The patent describes an exit sign with lighting heads mounted on a support assembly that allows for multiple axes of adjustment. The lighting head can be rotated "through an angle greater than 180°" about a vertical axis and can also be slidably adjusted along an arcuate path relative to the support arm, providing enhanced positioning flexibility ('808 Patent, Abstract; col. 2:35-44). The design uses mating facets between the support arms and a joint element to hold the head in discrete positions without separate fasteners ('808 Patent, col. 2:5-8).
  • Technical Importance: This invention allows for a "versatile exit sign" where lighting heads can be "readily repositioned" with "minimal effort" to achieve a more "advantageous lighting configuration" ('808 Patent, col. 2:49-54).

Key Claims at a Glance

  • The complaint asserts independent claim 1 (Compl. ¶32).
  • Essential elements of Claim 1:
    • a housing having a front face and a rear face with a peripheral edge therebetween, said housing being adapted to receive a lighting system including an illumination source and a power source;
    • symbols located on said front face adapted to be illuminated by the lighting system;
    • a support assembly mounted to said peripheral edge, said support assembly including a support arm defining a first axis;
    • a freely rotatable lighting head supported by said support arm for movement to any one of a plurality of selectable, discreet positions through an angle greater than 180° about the first axis; and
    • means for enabling sliding adjustment of said lighting head relative to said support arm.

U.S. Design Patent No. D440,336 - Lamp Support for Emergency Light Fixture (Issued Apr. 10, 2001)

Technology Synopsis

  • This patent protects the ornamental design for a lamp support fixture (Compl. ¶38). The claimed design consists of a flat, oblong base with mounting prongs, from which two parallel, U-shaped stems rise to hold a boxy, central lamp housing between them (’336 Patent, Figs. 1-6). The complaint reproduces Figure 1 of the '336 Patent to illustrate the claimed ornamental design for the lamp support (Compl. p. 10, FIG. 1).

Asserted Claims

  • Design patents contain a single claim for the ornamental design as shown and described in the drawings (Compl. ¶35).

Accused Features

  • The "Combo Emergency & Exit Lights," models CR and CG, are accused of infringing by incorporating the claimed ornamental features (Compl. ¶¶ 37, 40). A photograph of the accused 'CG' model is provided to show its alleged incorporation of the ornamental features of the '336 Patent (Compl. p. 11).

III. The Accused Instrumentality

Product Identification

  • The accused instrumentalities are three models of emergency lights: "Combo Emergency & Exit Lights" (models "CR" and "CG") and "Emergency Lights" (model "EL") (Compl. ¶18).

Functionality and Market Context

  • The CR and CG models are described as combination exit signs and emergency lights that feature illuminated "EXIT" lettering, an internal battery, and "two fully adjustable lighting heads" (Compl. ¶33). The EL model is described as having "fully adjustable lighting heads" (Compl. ¶27). The complaint alleges these products are sold in the United States in competition with the Plaintiff's products (Compl. ¶18).

a support assembly mounted to said peripheral edge, said support assembly including a support arm defining a first axis "Support arms are provided to support two fully adjustable lighting heads..." ¶33 col. 6:35-38
a freely rotatable lighting head supported by said support arm for movement to any one of a plurality of selectable, discreet positions through an angle greater than 180° about the first axis The lighting heads "may rotate more than 180 degrees through discreet positions." ¶33 col. 6:38-43
means for enabling sliding adjustment of said lighting head relative to said support arm "The lighting heads are slidable." ¶33 col. 6:43-46

Identified Points of Contention

  • Technical Questions: A primary factual question for both the '085 and '808 patents will be whether the accused products' adjustment mechanisms operate as claimed. The complaint's allegations that the heads are "rotatable" and "slidable" are conclusory (Compl. ¶¶ 27, 33). The case may turn on evidence demonstrating the precise nature and range of motion of the accused lighting heads.
  • Scope Questions (Means-Plus-Function): The final element of claim 1 of the '808 Patent is a means-plus-function limitation. Infringement requires showing the accused product contains a structure that performs the identical function ("enabling sliding adjustment") and is structurally the same as, or equivalent to, the "snap connector 62" sliding in an "elongated recess 65" as disclosed in the patent's specification ('808 Patent, col. 4:22-30, Fig. 11). The dispute will likely focus on whether the accused product's "slidable" heads incorporate this specific corresponding structure or a legal equivalent.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for analysis of most claim terms. However, one term in the '808 Patent stands out as critical.

  • The Term: "means for enabling sliding adjustment of said lighting head relative to said support arm" ('808 Patent, Claim 1).
  • Context and Importance: This term is drafted in means-plus-function format under 35 U.S.C. § 112(f). Its scope is not defined by the literal words but is limited to the specific structure disclosed in the specification for performing the recited function, and its equivalents. Practitioners may focus on this term because the entire infringement analysis for this element will depend on identifying the corresponding structure in the patent and comparing it to the structure of the accused products.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: A party seeking a broader scope might argue that the "function" is simply enabling any form of sliding, but this position is generally disfavored in means-plus-function analysis, which requires a structural inquiry.
    • Evidence for a Narrower Interpretation: The specification discloses a specific corresponding structure: a "snap connector 62" that is inserted into an "elongated recess 65" in the lighting head, allowing the head to be "shifted" along an "arcuate path" ('808 Patent, col. 4:22-30, col. 5:25-31, Figs. 9, 11). This detailed disclosure suggests the possibility that the claim's scope is narrowly tied to this specific snap-connector-in-recess mechanism and its structural equivalents.

VI. Other Allegations

  • Indirect Infringement: The complaint alleges that all Defendants induced infringement under 35 U.S.C. § 271(b) (Compl. ¶¶ 24, 30, 36). The factual basis for inducement is the allegation that the individual defendant, Kamran Neydavoud, had "full knowledge of the patents" and directed the infringing activities with the "intent to induce others to infringe" (Compl. ¶¶ 17, 24).
  • Willful Infringement: The complaint alleges that Defendants' infringement was "willfully and knowingly" committed for all asserted patents (Compl. ¶¶ 24, 30, 36). The basis for this allegation appears to be the alleged "full knowledge of the patents" by Mr. Neydavoud, which suggests an allegation of pre-suit knowledge (Compl. ¶17).

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

  • A central issue for the '808 patent will be one of claim scope under § 112(f): what is the specific structure corresponding to the "means for enabling sliding adjustment," and do the accused products contain that same structure or a legal equivalent? The answer will likely define the outcome of infringement for that claim.
  • A key evidentiary question for both utility patents will be one of functional operation: does the evidence show that the accused lighting heads actually rotate and slide in the specific manner required by the claims, particularly the "greater than 180°" rotation recited in claim 1 of the '808 patent?
  • For the '336 design patent, the case will turn on a question of ornamental similarity: will a comparison of the accused products' overall appearance to the design patent's figures, from the perspective of an ordinary observer, establish that the designs are substantially the same?
