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 states that prior art vibrating massage devices were often "bulky, get very hot, are noisy and/or are difficult to use for extended periods of time" (׳482 Patent, col. 1:29-33).
• The Patented Solution: The invention claims to solve these problems through a specific mechanical and thermal design. It describes a device with a drive mechanism (such as a "Scotch yoke") to convert a motor's rotary motion into a piston's linear reciprocating motion, a thermally conductive housing, and a dedicated heat sink to dissipate heat generated by the motor (׳482 Patent, col. 1:49-62, Fig. 2). The patent also details a quick-connect system, potentially magnetic, that allows for the easy exchange of massage heads, even while the device is operating (׳482 Patent, col. 6:46-68, col. 7:8-12).
• Technical Importance: This design approach addresses key usability issues in high-performance handheld massagers, aiming to improve thermal management and reduce noise, thereby enabling more robust and prolonged use.

Key Claims at a Glance

• The complaint asserts at least independent Claim 1 (Compl. ¶21).
• The essential elements of Claim 1 include:
  • a housing;
  • a piston with a distal end having a substantially cylindrical bore;
  • a motor within the housing to reciprocate the piston;
  • a drive mechanism controlling the piston's stroke length; and
  • a quick-connect system comprising the piston's distal end and a massage head, configured to secure the head by sliding it into the bore "while the piston reciprocates."
• The complaint does not explicitly reserve the right to assert dependent claims.

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

The Invention Explained

• Problem Addressed: Design patents do not address technical problems; they protect the non-functional, ornamental appearance of an article of manufacture.
• The Patented Solution: The D’317 Patent claims the specific ornamental design of a percussive massage device. The design, shown in Figures 1-8, features a T-shaped body with a vertical cylindrical handle and a horizontal body housing the massage mechanism (D’317 Patent, Figs. 1, 3). Key ornamental features include the overall proportions, the smooth transitions between the handle and the horizontal body, and the appearance of a vented cap on the end opposite the massage head. The massage head itself is shown in broken lines, indicating it is not part of the claimed design (D’317 Patent, Description).
• Technical Importance: The claimed design provides a distinct visual appearance for a percussive massage device in a competitive market.

Key Claims at a Glance

• The complaint asserts infringement of the single claim of the D'317 patent (Compl. ¶¶ 16, 25).
• The claim is 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 wide range of battery-powered percussive massagers sold by CVS, including models under the brand names Sharper Image, Homedics, Evertone, TRAKK, AmaMedic, and Pursonic (Compl. ¶¶ 13, 18).

Functionality and Market Context

• The accused products are described as "battery-powered percussive massagers" (Compl. ¶21). The complaint alleges these products are sold by Defendant in its stores and online (Compl. ¶4). Beyond this general categorization, the complaint does not provide specific technical details on the operation of the accused products' drive mechanisms, massage head attachment systems, or internal components.

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

’482 Patent Infringement Allegations

The complaint alleges that the accused products infringe at least Claim 1 of the ’482 patent, either literally or under the doctrine of equivalents (Compl. ¶21). The core allegations are summarized below.

D’317 Patent Infringement Allegations

The complaint alleges that at least the Pursonic 6-Speed Pro Massager Gun infringes the D’317 patent (Compl. ¶18). The infringement theory for a design patent rests on the "ordinary observer" test. Plaintiff's position is that the overall ornamental appearance of the accused product is substantially the same as the design claimed in the D'317 patent, to the point that an ordinary observer would be deceived into purchasing the accused product believing it to be the patented design (Compl. ¶25).

• Identified Points of Contention:
  • Technical Question (’482 Patent): A central question will be whether the accused products' head-attachment mechanisms meet the functional requirements of the claimed "quick-connect system". The complaint does not provide evidence that the accused products allow a user to attach a massage head "while the piston reciprocates," a specific function taught in the patent (׳482 Patent, col. 7:10-12) and recited in the claim. The nature of the accused "drive mechanism" will also be a key factual issue.
  • Scope Question (D’317 Patent): The dispute will turn on a visual comparison between the claimed design and the accused product. The question for the court will be whether the similarities in the overall T-shape, proportions, and visual elements are substantial enough to meet the ordinary observer test, or if the differences in specific contours, vents, and surface details are sufficient to distinguish them.

V. Key Claim Terms for Construction

For the ’482 patent, the construction of the following terms from Claim 1 may be central to the dispute.

• The Term: "quick-connect system ... configured to secure the first massaging head ... while the piston reciprocates"

  • Context and Importance: This term is highly specific and functional. The infringement analysis will depend on whether the accused products' attachment mechanisms can perform this action of connecting during operation. Practitioners may focus on this term because it appears to be a significant point of novelty that could narrow the claim's scope.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: A party might argue the term should cover any system that allows for rapid, tool-less attachment, focusing on the "quick-connect" aspect.
    • Evidence for a Narrower Interpretation: The explicit functional language "while the piston reciprocates" provides strong evidence for a narrower construction. The specification supports this by stating the design allows the head "to easily slip into the opening 608 even while the piston 608 is moving" (׳482 Patent, col. 7:10-12).

• The Term: "drive mechanism"

  • Context and Importance: This term's scope will determine what types of internal mechanics infringe. The complaint alleges the accused products have such a mechanism, but provides no detail.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim term itself is general and not explicitly limited. A party could argue it covers any mechanism that converts motor rotation to linear piston motion.
    • Evidence for a Narrower Interpretation: The specification heavily details a specific "Scotch yoke" drive mechanism (׳482 Patent, col. 5:1-14, Fig. 4). A defendant may argue that the claims, when read in light of the specification, should be construed as limited to a Scotch yoke or structurally similar mechanisms.

VI. Other Allegations

• Indirect Infringement: The complaint focuses on "direct infringement" by Defendant for its offers to sell and sales of the accused products (Compl. ¶¶ 11, 20). The complaint does not plead specific facts to support claims for induced or contributory infringement, such as allegations of active encouragement or knowledge that components are especially made for infringement.
• Willful Infringement: The complaint does not explicitly allege "willful" infringement or request enhanced damages under 35 U.S.C. §284. It does, however, request a declaration that the case is "exceptional" under 35 U.S.C. §285, which is the standard for an award of attorneys' fees (Compl., Prayer for Relief ¶5).

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

The resolution of this case may depend on the court’s answers to several central questions:

1. A key functional question for the ’482 patent will be one of operational capability: Do the attachment mechanisms of the accused products in fact allow a massage head to be secured "while the piston reciprocates," as strictly required by the language of Claim 1, or is this a distinguishing feature of the patented invention?
2. A core issue for the D’317 patent will be one of visual similarity: When viewed through the eyes of an ordinary observer familiar with percussive massagers, is the overall ornamental appearance of the accused Pursonic product "substantially the same" as the patented design, or are the visual differences significant enough to avoid confusion?
3. An evidentiary challenge will be mapping the complaint’s broad allegations to the varied designs of the numerous accused products. The case will require detailed factual development to establish how each distinct accused product, sourced from multiple manufacturers, meets every limitation of the asserted utility claim and mirrors the asserted design patent.
