- Plaintiff’s Counsel: Scheef & Stone, LLP
 
- Case Identification: 2:24-cv-00066, E.D. Tex., 04/15/2024
- Venue Allegations: Plaintiff alleges venue is proper because Defendant is a Texas corporation that has committed acts of infringement and maintains a regular and established place of business in the district.
- Core Dispute: Plaintiff alleges that Defendant’s line of percussive massage guns infringes a patent related to the mechanical design of such devices, particularly a system for quickly connecting and securing massage heads.
- Technical Context: The technology resides in the field of personal therapeutic devices, specifically handheld, battery-powered massagers used for deep muscle percussive therapy.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 11,857,482 - "Massage Device Having Variable Stroke Length"
- 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 notes that prior art vibrating massagers suffered from deficiencies such as being "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 is a handheld percussive massage device designed to address these issues. The design includes a motor that drives a piston in a reciprocating motion via a "Scotch yoke" drive mechanism (’482 Patent, col. 5:14-16). To mitigate noise and wear, the mechanism can incorporate spring bars to take up slack between moving parts, preventing them from striking each other during operation (’482 Patent, col. 5:43-48). The patent also describes a quick-connect system, which may use magnets, allowing a user to easily attach and detach different massage heads (’482 Patent, col. 6:46-57).
- Technical Importance: The described innovations aim to improve the user experience by creating a quieter, more durable, and more versatile percussive massager, facilitating the swapping of applicator heads to treat different muscle groups (’482 Patent, col. 6:49-54).
Key Claims at a Glance
- The complaint asserts independent Claim 1 (’482 Patent, Compl. ¶17).
- The essential elements of Claim 1 are:- a housing;
- a piston with a proximal end, a distal end, and a substantially cylindrical bore at its distal end;
- a motor within the housing that causes the piston to reciprocate;
- a drive mechanism controlling a predetermined stroke length of the piston; and
- a quick-connect system, comprising the piston's distal end and a massage head, configured to secure the head by sliding its proximal end into the bore while the piston is reciprocating.
 
III. The Accused Instrumentality
Product Identification
- The complaint names the Arboleaf Mini Massage Gun, Deep Tissue Massage Gun, and models CM40A, CM20C, and J2 as the accused products (Compl. ¶13).
Functionality and Market Context
- The complaint describes the accused products as "battery-powered percussive massage devices" (Compl. ¶17). It alleges these products are sold throughout the United States via online platforms such as Amazon.com and the defendant's own website (Compl. ¶4). The complaint alleges these devices possess the features recited in the asserted patent claim but does not provide specific technical details about their construction or operation beyond the infringement allegations themselves (Compl. ¶17).
IV. Analysis of Infringement Allegations
No probative visual evidence provided in complaint.
The complaint references a representative claim chart attached as Exhibit 2, but this exhibit was not included in the filing. The infringement theory, as described in the body of the complaint, alleges that the accused Arboleaf massagers directly infringe at least Claim 1 of the ’482 Patent (Compl. ¶17). The core of the allegation is that the accused products are percussive massagers that embody each structural and functional element of Claim 1. This includes having a housing, a motor-driven reciprocating piston with a bore, a drive mechanism, and a quick-connect system for attaching massage heads that allegedly meets all claim limitations (Compl. ¶17.a-e).
- Identified Points of Contention:- Technical Question: The complaint provides no specific evidence (e.g., from product manuals, marketing, or testing) that the accused devices' quick-connect system is, in fact, "configured to secure" a massage head while the piston is actively reciprocating, as required by the final clause of Claim 1. The infringement analysis will depend on factual evidence demonstrating this specific operational capability.
- Scope Question: A potential point of dispute is whether the accused products' attachment mechanism, even if it allows for insertion during operation, was intentionally "configured" for this purpose. The question for the court may be whether this claim language requires a design that affirmatively facilitates attachment while in motion, or whether it is met if the structure simply does not prevent it.
 
V. Key Claim Terms for Construction
- The Term: "quick-connect system ... configured to secure the first massaging head ... while the piston reciprocates"
- Context and Importance: The construction of this functional limitation will be critical to the infringement analysis. The dispute will likely focus on the meaning of "configured to" in the context of the device's operation. Practitioners may focus on this term because proving infringement requires demonstrating not just a structure, but a specific functional capability for which the complaint offers no direct evidence.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: A party may argue that "configured to" is met if the system's physical characteristics (e.g., tapered ends, magnetic attraction) inherently permit attachment during reciprocation. The specification notes that the massage head may be shaped "to allow it to easily slip into the opening 608 even while the piston 608 is moving" (’482 Patent, col. 7:9-12), which could support an interpretation based on physical possibility.
- Evidence for a Narrower Interpretation: A party may argue that "configured to" implies an intended, affirmative design for this function, which might be evidenced by user instructions or specific safety features. The patent states that the system "allows a user to quickly switch massaging heads" and "may be used without turning off the massaging device" (’482 Patent, col. 6:52-57), but a court could question whether this permissive language imposes a required functional configuration on all embodiments.
 
VI. Other Allegations
- Willful Infringement: The complaint alleges that Defendant’s infringement has been willful. The factual basis for this allegation is Defendant's alleged knowledge of the ’482 Patent "By no later than February 1, 2024," the date on which Plaintiff filed its original lawsuit against Defendant for infringement of the same patent (Compl. ¶14).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of functional configuration: Does the claim language "configured to secure ... while the piston reciprocates" require an affirmative design for attachment during operation, or is it met if the physical structure merely makes it possible? The case may turn on whether Plaintiff can prove the accused devices are not just capable of this function, but were specifically designed to perform it.
- A key evidentiary question will be one of operational proof: Beyond the conclusory allegations in the complaint, what factual evidence will be presented to show that the accused Arboleaf massagers actually perform the specific function of securing a massage head while the device is operating? The outcome will likely depend on evidence from product teardowns, testing, and internal design documents.
