- Plaintiff’s Counsel: SML AVVOCATI P.C.
- Case Identification: 8:23-cv-00345, C.D. Cal., 02/27/2023
- Venue Allegations: Venue is alleged to be proper in the Central District of California because Defendant is headquartered and/or has its primary place of business in the district.
- Core Dispute: Plaintiff alleges that Defendant’s pop-up canopy tents infringe a patent related to a pull-pin assembly used for locking telescoping poles.
- Technical Context: The technology concerns mechanical locking assemblies for adjustable, telescoping support poles commonly used in portable, collapsible structures like commercial and recreational canopies.
- Key Procedural History: The patent-in-suit is a reissue patent, which re-examined and re-issued an earlier patent. Reissue proceedings can alter claim scope and create prosecution history that may be relevant to future claim construction and estoppel arguments.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Reissue Patent No. RE40,657 - "Pull Pin Assembly for Canopy"
- Patent Identification: U.S. Reissue Patent No. RE40,657, "Pull Pin Assembly for Canopy," issued March 10, 2009. (Compl. ¶7).
The Invention Explained
- Problem Addressed: The patent's background section identifies that prior locking mechanisms for telescoping poles on portable canopies were often "difficult to assemble and mount, unnecessarily complicated, and often unreliable." (’657 Patent, col. 2:32-35).
- The Patented Solution: The invention provides an integrated pull-pin assembly designed for easy and secure use. It features a main body that fits over an outer canopy pole and houses a spring-loaded pull-pin. This pin engages aligned holes in the outer and inner telescoping poles to lock them at a desired height. A distinguishing feature is the method for securing the assembly to the outer pole, which utilizes "at least one resilient tab" with a "boss thereon" that engages a notch in the pole, intended to simplify manufacturing and assembly. (’657 Patent, col. 2:42-52; Fig. 2).
- Technical Importance: The design's stated purpose was to provide a locking mechanism for portable canopies that is "easy to produce, assemble, and use." (’657 Patent, col. 2:11-13).
Key Claims at a Glance
- The complaint asserts independent claim 18 and dependent claim 19. (Compl. ¶¶ 9-11).
- The essential elements of independent claim 18 include:
- A first (outer) rod or pole and a second (inner) rod or pole slidably contained within the first, each with a hole that can be aligned.
- A "main body" with a central hollow to contain the first pole.
- A "pull pin body" extending from the main body, which houses a movable "pull pin."
- A "biasing member" (e.g., a spring) that pushes the pull pin toward a locked position.
- A functional requirement that the main body is fixed against movement when the pin is disengaged (the "second position").
- A structural requirement that the main body is fixed to the first pole by a "boss" that engages a "third notch or hole" in the first pole.
- A further structural requirement that the "boss is formed on a resilient tab on the main body."
- The complaint notes that dependent claim 19 further specifies that the "resilient tab is cut out from the main body." (Compl. ¶10).
III. The Accused Instrumentality
Product Identification
- The complaint identifies a range of accused products, including the "10x10 Industrial Steel Pop Up Canopy Tent with Roller Bag – DS," "10x10 Heavy Duty Steel Pop up Canopy Tent with Roller Bag – CL," "iMega Series," and "Alumix Pop Up Canopy Tent," among others. (Compl. ¶11).
Functionality and Market Context
- The complaint alleges that these products are pop-up canopy tents that have been "made, used, offered for sale, sold and/or imported into the United States" by the Defendant. (Compl. ¶11). The infringing functionality is implied to be the locking mechanism used in the telescoping support poles of these canopies, which allegedly incorporates the patented pull-pin assembly. (Compl. ¶¶ 9, 11). The complaint does not provide further technical detail on the operation of the accused products.
IV. Analysis of Infringement Allegations
No probative visual evidence provided in complaint.
The complaint alleges that the accused products meet all limitations of at least claims 18 and 19. (Compl. ¶11). It does not, however, map specific features of the accused products to the claim elements. The following chart summarizes the infringement theory by referencing the complaint's recitation of the claim elements and its general allegation of infringement.

- Identified Points of Contention:
- Technical Questions: The complaint does not provide specific evidence (e.g., photographs, diagrams, or technical descriptions) showing how the accused products meet the claimed limitations. A central evidentiary question will be whether the accused products actually possess the specific mechanism recited in the latter elements of claim 18, namely a "boss" formed on a "resilient tab" used to fix the assembly to the pole. The defense may argue that the accused products use an alternative, non-infringing attachment method, such as screws, adhesives, or a simple friction fit.
V. Key Claim Terms for Construction
The Term: "resilient tab"
Context and Importance: This term is critical because it defines a key structural element for attaching the pull-pin assembly to the canopy pole. The scope of "resilient tab" will determine whether the claim covers a broad range of flexible attachment components or is limited to the specific structure shown in the patent.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term itself may be argued to have a plain and ordinary meaning of any tab that is flexible or capable of springing back.
- Evidence for a Narrower Interpretation: The specification describes a specific embodiment where "a resilient tab 26 is cut out from main body 21 by slots 28." (’657 Patent, col. 3:18-19; Fig. 2). Furthermore, dependent claim 19 explicitly adds the limitation "wherein resilient tab is cut out from the main body." (Compl. ¶10). A defendant may argue this disclosure limits the term in the independent claim or that the doctrine of claim differentiation implies the independent claim covers tabs that are not cut out from the main body.
The Term: "boss"
Context and Importance: This term, used in conjunction with "resilient tab," defines the specific structure that physically engages the pole to fix the assembly. Its definition is central to the infringement analysis, as it distinguishes the claimed invention from other potential fastening means.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A party could argue "boss" should be given its ordinary meaning in mechanics, referring to a generic protrusion or stud that fits into a hole or recess.
- Evidence for a Narrower Interpretation: The patent figures depict a specific, semi-cylindrical protrusion (element 27) that extends from the tab to engage a corresponding hole (60) in the pole. (’657 Patent, Fig. 6). A defendant may argue that the term "boss" should be limited to a structure that functions as described, i.e., "to fix the main body 21 to the assembly 20." (’657 Patent, col. 3:19-21).
VI. Other Allegations
- Indirect Infringement: The complaint alleges induced infringement under 35 U.S.C. § 271(b), stating on information and belief that Defendant acted with "full knowledge of the '657 patent and the specific intent that its acts and the acts of its customers" would constitute infringement. (Compl. ¶12). It further alleges Defendant actively induced infringement by intending for customers to use the accused products. (Compl. ¶14).
- Willful Infringement: The complaint alleges that Defendant’s infringement has been "deliberate and willful, at least since Defendant first learned about the '657 patent." (Compl. ¶15). This allegation appears to contemplate at least post-suit willfulness.
VII. Analyst’s Conclusion: Key Questions for the Case
This dispute centers on a mature and widely used mechanical technology. The outcome will likely depend on highly specific factual and legal determinations. Key questions for the court include:
- A core issue will be one of claim construction: how narrowly will the court define the terms "resilient tab" and "boss"? Will the definitions be limited to the specific embodiments shown in the patent figures and described in the specification, or will they be afforded a broader scope?
- A key evidentiary question will be one of factual correspondence: does the accused canopy locking mechanism actually contain the specific structure of a "boss on a resilient tab" that engages a hole to fix the assembly to the pole, as required by claim 18? Or does it achieve the same result through a mechanically different and thus non-infringing design?
