Case Timeline

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

U.S. Patent No. 11,857,482 - "Massage Device Having Variable Stroke Length" (Issued Jan. 2, 2024)

The Invention Explained

• Problem Addressed: The patent’s background section identifies deficiencies in prior art massaging devices, stating that many were "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 claims to solve these problems through a specific mechanical configuration and feature set. The specification describes a device with a motor and handle on opposite sides of a reciprocating piston, a "Scotch yoke" drive mechanism to reduce noise and wear, and a "quick-connect" system for attaching different massage heads (’482 Patent, Abstract; col. 5:13-14). A key aspect of the quick-connect system is that it is designed to allow a user to attach a massage head even while the piston is moving (’482 Patent, col. 7:10-14).
• Technical Importance: The described features aim to enhance the usability of personal massagers by simplifying the process of changing applicator heads and improving the device's thermal and acoustic performance (’482 Patent, col. 1:26-31; col. 6:40-44).

Key Claims at a Glance

• The complaint asserts infringement of at least independent Claim 1 (Compl. ¶21). The essential elements are:
  • a housing;
  • a piston having a proximal end and a distal end, the distal end of the piston having a substantially cylindrical bore;
  • a motor at least partially within the housing and operatively connected to the proximal end of the piston, wherein the motor is configured to cause the piston to reciprocate at a first speed;
  • a drive mechanism that controls a predetermined stroke length of the piston; and
  • a quick-connect system comprising the distal end of the piston and a first massaging head, wherein the quick-connect system is configured to secure the first massaging head to the percussive massager by a proximal end of the massaging head being slid into the bore while the piston reciprocates the predetermined stroke length at the first speed.

U.S. Design Patent No. D886,317 - "Percussive Massage Device" (Issued Jun. 2, 2020)

The Invention Explained

• Problem Addressed: Design patents do not solve technical problems; they protect the novel, non-functional, ornamental appearance of an article of manufacture.
• The Patented Solution: The patent claims the specific ornamental design for a percussive massage device as illustrated in its figures (D’317 Patent, Figs. 1-8). The design is characterized by its overall T-shaped configuration, the proportional relationship between the main cylindrical body and the perpendicular handle, and the specific visual treatment of its surfaces and apertures (D’317 Patent, Figs. 1, 3).
• Technical Importance: In the competitive consumer electronics market, a unique and recognizable product design can serve as a key differentiator and source of brand identity.

Key Claims at a Glance

• The patent contains a single claim for "The ornamental design for a 'percussive massage device,' as shown and described" (D’317 Patent, CLAIM).

III. The Accused Instrumentality

Product Identification

• The complaint accuses a broad category of "battery-powered percussive massagers" of infringing the ’482 Patent, listing examples from brands including Sharper Image, NuvoMed, Osaki, LifePro Fitness, Tzumi, Flynama, and Synca Wellness (Compl. ¶13). For the D’317 Patent, the allegations are directed specifically to the "NuvoMed Cordless Rechargeable Percussive Massager" (Compl. ¶18).

Functionality and Market Context

• The complaint alleges that these are deep tissue massage devices offered for sale and sold by Defendant Lowe's through its physical stores and website (Compl. ¶¶ 4, 13). The complaint does not provide detailed technical descriptions of the accused products' operation, instead alleging in a conclusory manner that they possess the features recited in the asserted patent claims (Compl. ¶21). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

’482 Patent Infringement Allegations

• Identified Points of Contention:
  • Technical Questions: The complaint's allegations regarding the internal components of the accused products (e.g., the "piston", "motor", and "drive mechanism") are made on information and belief. A central evidentiary question will be whether discovery confirms that the various third-party products sold by Lowe's actually contain internal structures that meet these claim limitations.
  • Scope Questions: The infringement analysis may turn on the functional language of the "quick-connect system" limitation. The court may need to determine whether this requires a system explicitly designed and advertised for "hot-swapping" massage heads, or if it is met by any design that incidentally allows a head to be inserted while the device is operating.

D’317 Patent Infringement Allegations

• The complaint alleges that the "NuvoMed Cordless Rechargeable Percussive Massager" infringes the ornamental design claimed in the D’317 Patent (Compl. ¶¶ 18, 25). The legal standard for design patent infringement is the "ordinary observer" test, which asks if an ordinary observer, familiar with the prior art, would be deceived into purchasing the accused product believing it was the patented design. As the complaint lacks any images of the accused NuvoMed product, a direct visual comparison is not possible from the pleading.
• Identified Points of Contention:
  • The dispositive issue for this claim will be a visual one: does the overall ornamental appearance of the accused NuvoMed massager create a visual impression that is substantially the same as the claimed design? This will require a side-by-side comparison of the accused product and the patent figures, focusing on similarities in shape, configuration, and surface ornamentation.

V. Key Claim Terms for Construction

• The Term: "quick-connect system ... configured to secure the first massaging head ... while the piston reciprocates" (from Claim 1 of the '482 Patent)

• Context and Importance: This functional limitation appears to be a primary point of novelty and is highly specific. The infringement determination for the ’482 patent may depend heavily on whether the accused products' attachment mechanisms are found to be "configured to" perform this "hot-swapping" function.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A patentee might argue the term should be read broadly to cover any design where the opening and massage head shaft are shaped to "allow it to easily slip into the opening ... even while the piston ... is moving" (’482 Patent, col. 7:10-14), regardless of whether the manufacturer explicitly instructs users to do so.
  • Evidence for a Narrower Interpretation: An accused infringer could argue that "configured to" implies a specific, intentional design for this function, not merely an incidental capability. They might point to the detailed description of the quick-connect system using magnets as the intended embodiment (’482 Patent, col. 6:57-66) to suggest the claim requires more than a simple friction fit.

• The Term: "drive mechanism" (from Claim 1 of the '482 Patent)

• Context and Importance: Practitioners may focus on this term because the specification provides a detailed description of a particular "Scotch yoke" drive mechanism intended to solve problems of noise and wear (’482 Patent, col. 5:13-26).

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patentee will likely argue that "drive mechanism" should be given its plain and ordinary meaning, encompassing any mechanical linkage that converts the motor's rotary motion into the piston's linear motion.
  • Evidence for a Narrower Interpretation: A defendant may argue that the extensive discussion of the Scotch yoke embodiment and its advantages limits the scope of "drive mechanism" to that specific structure or its close equivalents, potentially raising a question of prosecution history estoppel or specification disclaimer if other drive types were disavowed.

VI. Other Allegations

• Indirect Infringement: The complaint does not plead separate counts for indirect infringement (inducement or contributory infringement) and provides no specific factual allegations regarding knowledge or intent beyond what is required for direct infringement. The allegations focus on Defendant's direct infringement by "offer[ing] for sale and/or sell[ing]" the accused products (Compl. ¶20).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. The prayer for relief includes a request that the court declare the case "exceptional" under 35 U.S.C. §285, which could entitle the plaintiff to attorneys' fees (Compl. p. 7, ¶5). However, the complaint does not allege a factual basis for this request, such as pre-suit knowledge of the patents.

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

• A central issue for the ’482 utility patent will be one of evidentiary proof: what evidence will demonstrate that the internal mechanics of the numerous, distinct third-party products sold by Defendant Lowe's contain the specific "piston", "drive mechanism", and "quick-connect" structures as required by the asserted claim?
• A key question of claim scope will be the interpretation of the functional language in Claim 1 of the ’482 patent. Does the phrase "configured to secure the...head...while the piston reciprocates" require a specific mechanism intentionally designed for "hot-swapping," or can it be met by any attachment design that does not physically prevent such an action?
• The core of the design patent dispute will be a visual comparison: does the overall ornamental design of the accused NuvoMed massager create a substantially similar visual impression to an ordinary observer as the T-shaped design claimed in the D’317 patent, particularly when viewed in the context of other massage device designs in the prior art?
