2:24-cv-00799
Quickie Tie Down Enterprises LLC v. USA Products Group Inc
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Quickie Tie-Down Enterprises LLC (Arizona)
- Defendant: USA Products Group, Inc. (California); Stephen Jackson
- Plaintiff’s Counsel: Wheeler IP Law; Bycer & Marion
- Case Identification: 2:24-cv-00799, E.D. Cal., 02/14/2025
- Venue Allegations: Venue is alleged as proper because Defendants reside in the district, maintain a regular and established place of business there, and have committed the alleged acts of patent infringement within the district.
- Core Dispute: Plaintiff alleges that Defendants’ rope tie-down products infringe a patent related to a ratcheting mechanism designed for securing small-diameter cords, such as parachute cord.
- Technical Context: The technology concerns mechanical cargo restraints, specifically compact ratcheting devices that use frictional engagement to lock and tension small ropes or cords.
- Key Procedural History: The complaint alleges a long and contentious business history between the parties, beginning with failed acquisition negotiations around 1999 and a subsequent patent license agreement in 2005. Plaintiff alleges that during their business relationship, it confidentially disclosed the technology that would become the basis for the patent-in-suit, which Defendants then allegedly copied. The complaint also alleges that Defendant Jackson improperly filed for a separate patent (the '862 Patent) on inventions conceived by Plaintiff's principal. These allegations of a difficult history and misappropriation may be relevant to the claims of willful infringement.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,770,071, “Parachute Cord Tie Down,” issued Sep. 26, 2017
The Invention Explained
- Problem Addressed: The patent's background describes a need for a ratcheting mechanism specifically suited for small-diameter cords, which are distinct from the wider webbings or larger ropes handled by conventional ratchets (ʼ071 Patent, col. 1:12-18, 56-59).
- The Patented Solution: The invention is a compact tie-down device that uses a wheel and a spring-loaded pawl, both featuring "knurled" surfaces. A cord is passed between the wheel and the pawl. The knurled surfaces are designed to frictionally and mechanically grip the cord, preventing it from slipping in one direction (allowing tensioning) while permitting it to be pulled through in the other direction (ʼ071 Patent, col. 1:56-col. 2:2). Figure 9 of the patent provides an exploded view illustrating the relationship between the knurled wheel (130), knurled pawl (20), and other components (ʼ071 Patent, Fig. 9).
- Technical Importance: The design provides a simple, low-part-count ratchet specifically adapted for the unique handling requirements of small but strong cords like paracord (ʼ071 Patent, col. 2:12-16).
Key Claims at a Glance
- The complaint asserts independent claim 10 and reserves the right to assert additional claims (Compl. ¶¶78, 80).
- Essential elements of independent claim 10 include:
- A pair of sidewalls held together by bolts engaging a pair of bosses.
- A wheel, shaped like a cylindrical ring, rotatably supported on one boss.
- The wheel includes "knurling about the external cylindrical surface."
- A pawl, rotatably supported on a shaft, positioned near the wheel.
- The pawl includes "further knurling along one surface."
- A spring that biases the pawl toward the wheel to compress a parachute cord between the knurled surfaces.
- A hook attached to the other boss.
III. The Accused Instrumentality
Product Identification
The complaint names USA Products’ “6’ Better Than Bungee Tie Down,” sold under the “PROGRIP” brand (Model 055160), and the “Beyond Bungee Trek Rope Lock Tie-Down Tool” (No. 561900) as the infringing products (Compl. ¶¶79-82).
Functionality and Market Context
The accused products are described as tie-down devices with hooks at either end of a cord, which runs through a central locking mechanism (Compl. ¶80; p. 12). The complaint provides a photograph of the accused PROGRIP product's packaging, showing its overall configuration with hooks and a central locking body (Compl. p. 12). The packaging advertises a "Pull 'n' lock" function and a "Quick Release Tab," suggesting a one-way ratcheting or locking action (Compl. p. 12). The complaint alleges these products directly compete with Plaintiff's own "550 Paracord Military Quickie Tie-Down" (Compl. ¶54, 102).
IV. Analysis of Infringement Allegations
The complaint alleges that the accused products infringe at least claim 10 of the ’071 Patent, but the referenced claim chart exhibit is not included in the filing. The infringement theory can be summarized as follows:
'071 Patent Infringement Allegations
| Claim Element (from Independent Claim 10) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| (a) a pair of sidewalls; (b) a pair of bosses extending from one sidewall...into nested engagement with the other...; (c) a pair of bolts... | The plastic housing of the accused product, which is alleged to be constructed of two sides held together by internal bosses and external fasteners. | ¶80 | col. 3:11-31 |
| (d) a wheel in the shape of a cylindrical ring rotatably supported upon one boss...said wheel including knurling about the external cylindrical surface... | The internal mechanism of the accused product, which is alleged to contain a knurled wheel that allows the cord to be pulled through for tightening. | ¶80 | col. 4:6-9 |
| (e) a pawl rotatably supported on a shaft...said pawl including further knurling along one surface... | The internal locking element, operated by the "Quick Release Tab," which is alleged to be a knurled pawl that engages the cord against the wheel. | ¶80 | col. 4:11-13 |
| (f) a spring for biasing said pawl toward said wheel to urge compression of the parachute cord... | An internal spring mechanism alleged to provide the locking force for the pawl, which is released by the external tab. | ¶80 | col. 4:13-16 |
| (g) a hook attached to the other boss... | The metal hooks attached to the body of the accused device for securing it. | ¶80 | col. 3:45-50 |
Identified Points of Contention
- Technical Questions: A primary point of contention will likely be evidentiary. The complaint's visual evidence, including a screenshot of an Amazon product listing, does not show the internal components of the accused device (Compl. p. 14). The core of the infringement case may depend on what discovery reveals about the internal structure: specifically, whether it contains a "wheel" and "pawl" with surface features that meet the "knurling" limitation of claim 10.
- Scope Questions: The use of "parachute cord" in the preamble of claim 10 raises the question of whether this term limits the scope of the claim. A court may need to determine if the claim is limited to devices used with authentic parachute cord or if the term is merely illustrative of a general class of small-diameter cords.
V. Key Claim Terms for Construction
The Term: "knurling"
Context and Importance
This term is at the technical heart of the invention, defining the gripping surfaces of both the wheel and the pawl. The definition of "knurling" will be critical, as the patent also uses the term "toothed" in its description and in other claims (e.g., independent claim 1). Practitioners may focus on this term because the doctrine of claim differentiation could be invoked to argue that "knurling" must mean something different from "teeth."
Intrinsic Evidence for Interpretation
- Evidence for a Broader Interpretation: The patent’s "Summary of the Invention" states that the spool and pawl can have "either a knurled surface or a toothed surface," which may suggest the terms are interchangeable or that one is a species of the other ('071 Patent, col. 1:60-63).
- Evidence for a Narrower Interpretation: The fact that claim 1 recites "teeth" while claim 10 recites "knurling" provides a basis for arguing they must have distinct meanings. Figure 9 depicts the knurling (136) as a specific cross-hatched pattern, which could be argued as the required structure for the term ('071 Patent, Fig. 9).
VI. Other Allegations
Indirect Infringement
The complaint alleges induced infringement against Defendant Stephen Jackson individually (Count IV). It claims that as the sole officer and owner of USA Products, he was personally responsible for and directed the company to copy Plaintiff's invention with the specific intent to infringe the ’071 Patent (Compl. ¶¶105-107).
Willful Infringement
The complaint alleges willful infringement based on both pre- and post-suit conduct. It alleges pre-suit knowledge based on direct notice given at a 2017 or 2018 trade show (Compl. ¶91). It further supports willfulness by alleging a pattern of bad faith, including that Defendants copied the invention from a confidential prototype provided by Plaintiff and then attempted to pass off the invention as their own (Compl. ¶¶44-45, 86).
VII. Analyst’s Conclusion: Key Questions for the Case
- Evidentiary Match: A key evidentiary question will be one of technical correspondence: does the internal mechanism of the accused "PROGRIP" product, once revealed through discovery, actually contain a rotating wheel and a cooperating pawl with surface textures that meet the specific "knurling" limitation of Claim 10, or is there a fundamental mismatch in its mechanical structure and operation?
- Definitional Scope: The case may pivot on a question of claim construction: can the term "knurling", as used in claim 10, be interpreted to cover any friction-enhancing surface, or is its meaning narrowed by the patent's distinct use of the term "teeth" in other claims, thereby requiring a specific type of surface pattern for infringement?
- State of Mind: Given the extensive allegations of a contentious business history, misappropriation of confidential disclosures, and direct pre-suit notice, a central issue will be the Defendants' intent. The court will likely examine whether the alleged conduct constitutes objective recklessness sufficient for willful infringement and the specific intent required for the inducement and false marking claims.
