Case Timeline

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

• Patent Identification: U.S. Patent No. 11,857,482, "Massage Device Having Variable Stroke Length," issued January 2, 2024.

The Invention Explained

• Problem Addressed: The patent's background section identifies deficiencies in prior art massaging devices, stating they are often "bulky, get very hot, are noisy and/or are difficult to use for extended periods of time" (’482 Patent, col. 1:28-31).
• The Patented Solution: The invention describes a handheld percussive massager with an improved internal architecture. This includes a specific "Scotch yoke" drive mechanism for converting the motor's rotary motion into the piston's linear, reciprocating motion, a dedicated cooling system to manage heat, and a quick-connect system for easily swapping massage heads (’482 Patent, col. 5:1-14; col. 6:46-56). The design aims to create a more robust, user-friendly, and durable device.
• Technical Importance: The described combination of features seeks to address key usability issues in handheld massagers, particularly by simplifying the process of changing applicator heads and improving thermal management during operation (’482 Patent, col. 6:9-14, 50-56).

Key Claims at a Glance

• The complaint asserts infringement of at least independent Claim 1 (Compl. ¶17).
• The essential elements of Claim 1 are:
  • a housing;
  • a piston with a "substantially cylindrical bore" at its distal end;
  • a motor to cause the piston to reciprocate;
  • a drive mechanism controlling a "predetermined stroke length";
  • a "quick-connect system" configured to secure a massaging head that is slid into the bore "while the piston reciprocates."
• The complaint’s use of "at least Claim 1" suggests the right to assert other claims, including dependent claims, may be reserved for later stages of litigation (Compl. ¶17).

III. The Accused Instrumentality

Product Identification

The complaint names "all Cotsoco massage guns, including but not limited to the Mini Massage Gun, the 30 Speed Massage Gun, the Deep Tissue 30 Speed Massage Gun, and the 6 Speed Rechargeable Massage Gun" as the accused instrumentalities (Compl. ¶14).

Functionality and Market Context

• The accused products are described as "battery-powered percussive massagers" (Compl. ¶¶6-7). The complaint alleges these products incorporate the features recited in Claim 1 of the ’482 patent but does not provide further independent technical description of their operation (Compl. ¶17).
• The complaint alleges the products are sold to consumers in the district and throughout the United States via Amazon.com and Defendant's website, cotsoco.us (Compl. ¶5). Figure 6A of the patent, attached as an exhibit to the complaint, illustrates a disconnected view of a quick-connect mechanism, showing the massage head shaft and the piston bore separately ('482 Patent, FIG. 6A).

IV. Analysis of Infringement Allegations

'482 Patent Infringement Allegations

Identified Points of Contention

• Technical Question: The complaint alleges the accused products’ quick-connect systems are configured to secure a massage head "while the piston reciprocates." A central evidentiary question will be whether the accused products are in fact designed for, or capable of, this specific function. The complaint does not provide supporting evidence, such as user manual excerpts or video, to demonstrate this operational capability.
• Scope Question: The patent specification describes a magnetic quick-connect system as an exemplary embodiment (’482 Patent, col. 6:57-68). The infringement analysis may raise the question of whether the term "quick-connect system" in Claim 1 should be construed to cover other non-magnetic connection mechanisms (e.g., friction-fit or spring-detent systems) that may be used in the accused products.

V. Key Claim Terms for Construction

• The Term: "...configured to secure the first massaging head... while the piston reciprocates..."
• Context and Importance: This phrase appears to be the most technically specific and potentially distinguishing limitation in Claim 1. The outcome of the infringement analysis could depend heavily on its construction, as it defines a dynamic functional capability, not just a static structure.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: A party could argue that "configured to" means the structure is merely "capable of" performing the function, regardless of whether it is an intended or advertised use. The patent states the design is intended "to allow it to easily slip into the opening... even while the piston... is moving," which may be argued as describing a capability inherent in the structure (’482 Patent, col. 7:9-12).
  • Evidence for a Narrower Interpretation: A party could argue that "configured to" implies intentional design for a specific purpose, not just incidental capability. They might contend that without features expressly designed to facilitate connection during motion, a product is not "configured" for that function, even if it is physically possible under certain conditions.

VI. Other Allegations

The complaint does not contain allegations of indirect or willful infringement.

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

• A central issue will be one of functional operation: Can Plaintiff produce evidence that the accused Cotsoco massagers are, in fact, "configured to" allow for the attachment of a massage head while the device's piston is actively reciprocating? The resolution of this factual question will be critical to the infringement analysis for Claim 1.
• The case may also turn on a question of claim scope: Will the term "quick-connect system" be interpreted broadly to cover any mechanism for rapid attachment, or will its scope be influenced by the specific magnetic embodiment detailed in the patent's specification? The answer will determine what range of alternative designs, potentially used by the Defendant, fall within the patent's reach.
