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

U.S. Patent No. 11,857,482 - Massage Device Having Variable Stroke Length

  • Issued: January 2, 2024

The Invention Explained

  • Problem Addressed: The patent describes prior art vibrating massagers as suffering from deficiencies such as being "bulky, get[ting] very hot, are noisy and/or are difficult to use for extended periods of time" (’482 Patent, col. 1:27-30).
  • The Patented Solution: The invention is a handheld percussive massager designed for improved robustness and user experience. It features a motor that drives a piston in a reciprocating motion via a drive mechanism (e.g., a "Scotch yoke"), creating the percussive massage action (’482 Patent, col. 5:1-14). A key aspect is a "quick-connect system" at the end of the piston, allowing for the easy attachment and detachment of different massaging heads, for example, using magnets (’482 Patent, col. 6:47-66). The design aims to manage heat and reduce operational noise.
  • Technical Importance: The described combination of a robust drive mechanism and an interchangeable head system addresses practical usability issues, allowing for a more versatile and durable device suitable for deep tissue massage.

Key Claims at a Glance

  • The complaint asserts infringement of at least independent Claim 1 (Compl. ¶29).
  • The essential elements of Claim 1 include:
    • a housing
    • a piston with a proximal end and a distal end, where the distal end has a substantially cylindrical bore
    • a motor within the housing connected to the piston's proximal end, configured to make the piston reciprocate
    • a drive mechanism controlling a predetermined stroke length of the piston
    • a quick-connect system at the piston's distal end for securing a massaging head that is slid into the bore, even while the piston is reciprocating
  • The complaint pleads infringement under the doctrine of equivalents as an alternative to literal infringement (Compl. ¶32).

III. The Accused Instrumentality

Product Identification

The accused products are percussive massagers sold under the brand name “Morelax Gun” through Defendant’s Amazon storefront, identified at least by ASIN B0CP3K8G9X (Compl. ¶8, ¶24).

Functionality and Market Context

The complaint describes the accused products as "battery-powered percussive massagers" (Compl. ¶30). It alleges they are sold at "significantly below-market prices" and that Defendant targets and ships them to customers in the U.S. (Compl. ¶2.b, ¶22). The complaint does not provide further technical detail on the operation of the Morelax Gun beyond alleging that it incorporates the features recited in the asserted patent claim.

No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint references a claim chart in a separate declaration that was not provided with the complaint itself (Compl. ¶29). The following summary is based on the narrative allegations in the body of the complaint, which lists the elements of Claim 1 and alleges they are met by the Infringing Products (Compl. ¶31, ¶32).

’482 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a housing; The complaint alleges the Infringing Products include a housing. ¶32.a col. 3:34-39
a piston having a proximal end and a distal end, the distal end of the piston having a substantially cylindrical bore; The complaint alleges the Infringing Products include a piston with a proximal and distal end, with the distal end having a bore. ¶32.b col. 3:46-48
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; The complaint alleges the Infringing Products include a motor within the housing that drives the piston to reciprocate. ¶32.c col. 3:38-40
a drive mechanism that controls a predetermined stroke length of the piston; and The complaint alleges the Infringing Products include a drive mechanism that controls the piston's stroke length. ¶32.d col. 5:1-14
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...by a proximal end of the massaging head being slid into the bore while the piston reciprocates the predetermined stroke length... The complaint alleges the Infringing Products include a quick-connect system that secures the massage head as functionally described. ¶32.e col. 6:47-57
  • Identified Points of Contention:
    • Technical Questions: A primary question will be evidentiary: what is the actual internal construction of the accused "Morelax Gun"? The complaint does not provide diagrams or a teardown analysis. The court will need to assess whether the accused product contains a "drive mechanism" and a "quick-connect system" that operate in the manner required by the claim.
    • Scope Questions: The functional language of the "quick-connect system" limitation—requiring it to be "configured to secure the first massaging head... while the piston reciprocates"—may be a focal point. The dispute may turn on whether the accused product's attachment mechanism is robust enough to meet this functional requirement, or if it is merely a simple friction fit that is not "configured" for attachment during operation.

V. Key Claim Terms for Construction

  • The Term: "quick-connect system"

    • Context and Importance: This term is central to the invention's user-facing functionality. Its construction will determine what types of head-attachment mechanisms fall within the claim's scope. Practitioners may focus on this term because the patent specification discloses a specific magnetic embodiment for this system (’482 Patent, col. 6:56-66), which could raise arguments about whether the claim scope is limited to that embodiment or similar magnetic systems.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The claim language itself is functional, defining the system by what it does ("configured to secure the first massaging head"). This may support an interpretation that covers any mechanism (magnetic, mechanical latch, friction fit) that achieves the stated function.
      • Evidence for a Narrower Interpretation: The detailed description focuses on a magnetic implementation where magnets in the piston and the massaging head attract one another (’482 Patent, col. 6:56-66). A defendant may argue this disclosure limits the scope of the term to magnetic systems or those structurally equivalent.

  • The Term: "drive mechanism"

    • Context and Importance: This term defines the core mechanical linkage between the motor and the piston. The complaint’s lack of technical detail about the accused product’s internals makes the scope of this term critical.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The term itself is generic. Plaintiff may argue it should be given its plain and ordinary meaning, covering any mechanical linkage that converts the motor's motion and controls the piston's stroke length.
      • Evidence for a Narrower Interpretation: The specification describes a specific "Scotch yoke" as the mechanism for converting rotary to linear motion (’482 Patent, col. 5:1-14). A defendant could argue that this is the "invention" and that the term "drive mechanism" should be construed to be limited to a Scotch yoke or a structure that is insubstantially different.

VI. Other Allegations

  • Indirect Infringement: The complaint makes a passing allegation of Defendant "indirectly developing, designing, manufacturing..." products (Compl. ¶24). However, it does not plead a formal count for indirect infringement (inducement or contributory) or provide specific factual allegations to support the required elements of knowledge and intent, such as referencing user manuals or advertising materials that instruct on an infringing use.
  • Willful Infringement: The complaint does not use the term "willful," but it alleges that Defendant is "aware of Plaintiff, its products and the Hyperice Patent" (Compl. ¶3.e) and requests enhanced damages under 35 U.S.C. §284 (Prayer for Relief ¶5). This forms the basis for a potential claim of willful infringement based on alleged pre-suit knowledge of the patent and the infringing nature of its conduct.

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

The resolution of this dispute will likely depend on the answers to two central questions:

  1. A core issue will be one of claim construction: Can the term "quick-connect system", which is described in the patent with a specific magnetic embodiment, be construed broadly enough to read on the likely friction-fit or simple mechanical latch systems used in lower-cost competing products?

  2. A key evidentiary question will be one of technical proof: As the case proceeds into discovery, what evidence will emerge from an inspection of the accused "Morelax Gun"? The infringement analysis will turn entirely on whether that device contains the specific components (e.g., a "drive mechanism", a "piston" with a "bore") that function in the precise manner required by the asserted claim.
