Jump Rope Systems LLC v. Smith Ventures Ltd
Key Events
Complaint
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Jump Rope Systems, LLC (Colorado)
- Defendant: Smith Ventures, Ltd. (Colorado)
- Plaintiff’s Counsel: LIMPUS + LIMPUS, PC
- Case Identification: 1:16-cv-01818, D. Colo., 07/16/2016
- Venue Allegations: Venue is alleged to be proper in the District of Colorado because Defendant is incorporated in Colorado, transacts business in the district, and has allegedly committed acts of patent infringement there.
- Core Dispute: Plaintiff alleges that Defendant’s RAGE R1 Speed Rope infringes two patents related to high-performance jump rope handle technology featuring low-friction bearings and pivoting cable connections.
- Technical Context: The technology addresses mechanical limitations in conventional jump ropes, aiming to increase rotation speed and smoothness for use in sports and fitness activities like speed jumping.
- Key Procedural History: The complaint alleges that the parties had a prior patent license agreement, which Plaintiff's predecessor-in-interest terminated due to Defendant's alleged failure to pay royalties. Subsequent to the complaint's filing, Inter Partes Review (IPR) proceedings were initiated against both patents-in-suit. These proceedings resulted in the cancellation of all claims of the ’809 Patent (IPR2019-00586) and all claims of the ’208 Patent (IPR2019-00587) in August 2022, a fact that raises a threshold question about the viability of the infringement claims as pleaded.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,789,809 - "Jump Rope System," issued September 7, 2010
The Invention Explained
- Problem Addressed: The patent's background section identifies three problems with conventional jump ropes that limit rotation speed: (1) high rotational resistance within the handle; (2) suboptimal positioning of the cable relative to the handle, causing contact; and (3) the failure of the handle-to-cable connection to allow for both swiveling and pivoting motion ('809 Patent, col. 1:16-44).
- The Patented Solution: The invention is a complete jump rope system featuring handles that contain a shaft rotating on one or more bearing elements to minimize friction. The shaft extends outward from the handle and connects to the cable via a "blade element" and a "ball element," which together create a pivot point that allows for multi-axis movement of the cable relative to the handle ('809 Patent, Abstract; col. 2:31-48). This combination is intended to enable a faster, more controllable, and less restricted rotation.
- Technical Importance: The described technology aims to provide a mechanical advantage for skilled "rope jumpers [who] strive to achieve at increasingly greater jump rope spin or turn rates" ('809 Patent, col. 1:10-12).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶32).
- The essential elements of claim 1 are:
- A jump rope system comprising a pair of handles and a cable element.
- Each handle comprises a shaft that is "rotatably journaled in at least one bearing element" and retained by the handle.
- A "blade element" is coupled to the shaft and extends outward from the handle.
- A "ball element" is "pivotally coupled within an aperture" of the blade element.
- The cable element is coupled to the ball element at its opposed ends.
- The complaint alleges infringement of "at least Claim 1" ('809 Patent, Compl. ¶32).
U.S. Patent No. 8,136,208 - "Handle System," issued March 20, 2012
The Invention Explained
- Problem Addressed: The '208 Patent addresses the same technical problems as its parent '809 Patent: rotational resistance and restricted movement in conventional jump rope handles ('208 Patent, col. 1:18-49).
- The Patented Solution: This patent claims the handle system itself, rather than the entire jump rope. The core inventive concept remains a handle that houses a shaft on at least one bearing element, with the shaft terminating in a specific pivoting assembly comprising a "blade element" and a "ball element" to facilitate free rotation and movement of an attached cable ('208 Patent, Abstract; col. 2:50-65).
- Technical Importance: By claiming the handle as a standalone system, the invention could be applied to replacement handles or modular jump rope systems, targeting the same high-performance user base.
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶41).
- The essential elements of claim 1 are:
- A handle comprising a shaft "rotatably journaled in at least one bearing element."
- The shaft has a first end extending outward from the handle, which comprises a "blade element" that bounds an "aperture element."
- A "ball element" is "pivotally coupled within said aperture element" and is adapted to couple to a cable.
- The complaint alleges infringement of "at least Claim 1" ('208 Patent, Compl. ¶41).
III. The Accused Instrumentality
Product Identification
- The accused product is the "RAGE R1 Speed Rope," which is part of Defendant's "RAGE Fitness line of products" (Compl. ¶27).
Functionality and Market Context
- The RAGE R1 Speed Rope is marketed as "the world's fastest speed rope" with "technically superior speed bearings to ensure fluid and precise movement at high speeds" (Compl. ¶29). A screenshot from Defendant's website shows the RAGE R1 Speed Rope, including its handle and cable, and offers it for sale (Compl. p. 6). The product is sold through multiple commercial channels, including Defendant's website, Amazon.com, and major sporting goods retailers (Compl. ¶28). The marketing language suggests the product is positioned to compete in the high-performance or fitness-oriented segment of the jump rope market.
IV. Analysis of Infringement Allegations
'809 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a pair of handles each comprising: i) a shaft rotatably journaled in at least one bearing element | The accused rope allegedly contains handles with "technically superior speed bearings" that permit a shaft to rotate (Compl. ¶29), which Plaintiff alleges meets this limitation. | ¶34, ¶29 | col. 2:41-48 |
| ii) a handle adapted to retain said shaft rotatably journaled in said at least one bearing element | The accused handle physically contains the allegedly rotating shaft and bearing assembly. | ¶34 | col. 3:45-51 |
| iii) a blade element coupled to said shaft, said blade element extending axially from said shaft a distance outward from said handle | The complaint makes a conclusory allegation that the accused product contains a blade element with this configuration. | ¶34 | col. 5:11-20 |
| iv) a ball element pivotally coupled within an aperture of said blade element a distance from said handle | The complaint makes a conclusory allegation that the accused product contains a ball element pivotally coupled as claimed. | ¶34 | col. 6:45-56 |
| b) a cable element having one of a pair opposed ends coupled to said ball element | The accused product's cable is allegedly connected to the pivoting ball element at the end of the handle mechanism. | ¶34 | col. 6:63-65 |
'208 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| a) a handle which retains within a shaft rotatably journaled in at least one bearing element | The accused handle is alleged to contain a shaft rotating on bearings to ensure "fluid and precise movement" (Compl. ¶29). | ¶43, ¶29 | col. 3:48-54 |
| b) a first shaft end extending axially outward of said handle, wherein said first shaft end comprises a blade element which bounds an aperture element at a distance from said handle | The complaint alleges, without specific factual support, that the accused handle's shaft has a blade element as claimed. | ¶43 | col. 5:15-21 |
| c) a ball element pivotally coupled within said aperture element, said ball element adapted to couple to a cable element | The complaint alleges that the accused product contains a ball element connected as described in the claim. | ¶43 | col. 6:50-58 |
Identified Points of Contention
- Threshold Legal Question: Arising from the post-filing IPRs, the central legal question is whether Plaintiff has a valid cause of action for patent infringement when the asserted claims of both patents were subsequently cancelled.
- Technical Questions: The complaint relies on marketing materials and conclusory allegations (Compl. ¶¶34, 43). A key factual dispute would concern the actual mechanical structure of the accused RAGE R1 Speed Rope's handle-to-cable connection. The case would require evidence showing whether that connection functions as a "blade element" with a "ball element pivotally coupled within" it, as opposed to another type of pivoting or rotating mechanism.
V. Key Claim Terms for Construction
The Term: "blade element"
- Context and Importance: This term defines the specific structure at the end of the shaft that facilitates the pivotal connection. The infringement analysis for both patents hinges on whether the accused product's connector can be properly characterized as a "blade element." Practitioners may focus on this term because it is a non-standard term of art whose scope will be defined by the patent's specification.
- Intrinsic Evidence for a Broader Interpretation: The specification describes the element as "providing a pair of generally circular... or rectangular... planar surfaces disposed in substantially opposed parallel relation" ('809 Patent, col. 5:15-19), suggesting the term is not limited to a single shape but rather to its function of providing parallel surfaces to create an aperture.
- Intrinsic Evidence for a Narrower Interpretation: The figures consistently depict the "blade element" (40) as a specific forked or clevis-style structure (e.g., '809 Patent, Figs. 10-11). A party could argue the term should be construed more narrowly to match these depicted embodiments.
The Term: "pivotally coupled within an aperture"
- Context and Importance: This phrase describes the nature of the connection between the "ball element" and the "blade element." The precise mechanics of this coupling are critical to determining infringement.
- Intrinsic Evidence for a Broader Interpretation: The patent explains that the purpose of the pivot is to allow the handle to travel within a "swivel range" and a "pivot range" relative to the cable, preventing binding ('809 Patent, col. 6:1-35). This functional description could support a construction that covers any joint achieving this specific multi-axis freedom of movement.
- Intrinsic Evidence for a Narrower Interpretation: The specification discloses a specific embodiment of a "ball (54) pivotally coupled to the first shaft end (34)" ('809 Patent, col. 6:46-47) and shows it residing inside the aperture (Fig. 11). This could support a narrower construction requiring a true ball-in-socket or ball-in-clevis arrangement, potentially excluding other types of pivoting joints.
VI. Other Allegations
- Indirect Infringement: The complaint's prayer for relief seeks a judgment for inducement and contributory infringement (Compl. p. 11, ¶¶B, C). However, the factual allegations in the body of the complaint focus exclusively on direct infringement and do not plead the specific elements of knowledge and intent required for indirect infringement claims.
- Willful Infringement: The complaint alleges that Defendant's infringement was willful, deliberate, and intentional (Compl. ¶¶36, 45). The factual basis for this allegation is the prior patent license agreement between Defendant and the patents' inventor, which was allegedly in effect from May 2012 to December 2015 (Compl. ¶¶14, 19). This history, if proven, may support a finding of pre-suit knowledge of the patents and their alleged relevance to the accused products.
VII. Analyst’s Conclusion: Key Questions for the Case
- Primary Jurisdictional Question: The primary issue in this case is a threshold legal question of survivability: given that all asserted claims of both patents-in-suit were cancelled in Inter Partes Review proceedings subsequent to the filing of the complaint, can any cause of action for patent infringement from the period pre-dating cancellation proceed?
- Definitional Scope Question: Assuming the claims were valid, a central issue would be one of definitional scope: can the term "blade element", as described and depicted in the patents, be construed to read on the specific mechanical connector used in the accused RAGE R1 Speed Rope, or is there a fundamental structural difference?
- Evidentiary Question: The case would present a key evidentiary question of operational equivalence: what technical evidence demonstrates that the accused product’s handle mechanism, particularly its bearing and pivot assembly, actually operates in the specific manner required by the claim limitations, beyond the general marketing claims of "fluid and precise movement" cited in the complaint?
