I. Executive Summary and Procedural Information

  • Parties & Counsel:
  • Case Identification: 2:10-cv-07930, C.D. Cal., 10/21/2010
  • Venue Allegations: Venue is alleged to be proper in the Central District of California because Defendant conducts substantial business in the state and the acts giving rise to the lawsuit occurred within the district.
  • Core Dispute: Plaintiffs allege that Defendant has engaged in a widespread campaign of false patent marking on its exercise equipment in violation of 35 U.S.C. § 292, by marking products with patent numbers that have expired, that do not cover the products, and with "patents pending" when no applications are pending.
  • Technical Context: The dispute centers on patent markings applied to commercial-grade exercise and rehabilitation equipment, a market where intellectual property is often used to deter competition.
  • Key Procedural History: The complaint alleges that Defendant has a history of false marking, citing a 2006 jury verdict in Icon Health & Fitness, Inc. v. Nautilus Group, Inc., which found Nautilus liable for false marking and imposed a $325,000 penalty. Plaintiffs leverage this prior verdict to support allegations that any ongoing false marking is intentional.

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

This action is brought under 35 U.S.C. § 292 for false marking, not patent infringement. Dozens of patents are identified on accused products, but none are asserted for infringement. The core allegation is that the listed patents are either expired or do not cover the products they are marked on (Compl. ¶ 1). The following patents are representative of those central to the false marking allegations.

U.S. Patent No. 3,858,873 - "Weight Lifting Exercising Devices"

  • Patent Identification: U.S. Patent No. 3,858,873, "Weight Lifting Exercising Devices", issued January 7, 1975.

The Invention Explained

  • Problem Addressed: The patent describes a problem in conventional weight lifting where the resistance provided by a weight does not match the changing strength of human muscles throughout a rotational movement, leading to "sticking points" where the exercise feels heavy and other points where there is little resistance (Compl. ¶ 17; ’873 Patent, col. 1:45-68).
  • The Patented Solution: The invention is an exercise machine that uses a "force resolving spiral means," such as a specially shaped pulley or cam, connected to the weight stack (Compl. ¶ 17; ’873 Patent, col. 2:15-24, Abstract). This cam varies the effective resistance throughout the user's range of motion to match the muscle's natural strength curve, providing a more balanced and efficient workout (Compl. ¶ 17; ’873 Patent, Abstract).
  • Technical Importance: This approach of using non-circular pulleys (cams) to create variable resistance was a significant development in exercise machine technology, allowing for workouts that were biomechanically matched to human physiology (Compl. ¶¶ 26-29).

Key Claims at a Glance

  • No claims are asserted for infringement. The complaint alleges this patent, which expired in 1992, is falsely marked on numerous products manufactured in 2006 and later (Compl. ¶¶ 17, 42.a).

U.S. Patent No. 3,998,454 - "Force Receiving Exercising Member"

  • Patent Identification: U.S. Patent No. 3,998,454, "Force Receiving Exercising Member", issued December 21, 1976.

The Invention Explained

  • Problem Addressed: This patent addresses the same general problem as the ’873 Patent: matching exercise resistance to the user's strength curve during a rotational exercise (Compl. ¶ 17; ’454 Patent, col. 2:40-52).
  • The Patented Solution: The invention is a specific L-shaped lever assembly for use in an exercise machine, which serves as the interface between the user and the machine's resistance mechanism (Compl. ¶ 17; ’454 Patent, Abstract). The lever is designed to be attached to a rotatable hub, which would in turn be connected to a variable resistance system like the cam described in the ’873 patent (Compl. ¶ 17; ’454 Patent, col. 1:50-55).
  • Technical Importance: This patent covers a specific component—the user-interface lever—within the broader variable-resistance machine architecture, reflecting the granular patenting strategy for exercise equipment components (Compl. ¶¶ 11-13).

Key Claims at a Glance

  • No claims are asserted for infringement. The complaint alleges this patent, which expired in 1993, is falsely marked on numerous products manufactured in 2006 and later (Compl. ¶¶ 17, 42.a).

Multi-Patent Capsule: Unrelated Technology

  • Patent Identification: U.S. Patent No. 4,257,592, "Exercising Apparatus with Improvements in Handle Structure, Rope Arrangement, and Clamping Means", issued March 24, 1981.
  • Technology Synopsis: This patent is directed to an exercising apparatus using a handle, rope, and clamping means (Compl. ¶ 42.a). The technology involves a user pulling on handles connected by a rope, with a mechanism to adjust the rope's effective length.
  • Asserted Claims: No claims asserted for infringement.
  • Accused Features: The complaint alleges this patent is marked on numerous Nautilus machines, including the "2006 Nitro Plus Biceps Curl," but that the patent does not cover the machine's actual structure or function (Compl. ¶ 42.a). This forms the basis for an allegation of marking with an unrelated patent.

III. The Accused Instrumentality

Product Identification

  • The complaint accuses multiple Nautilus product lines sold since at least 2006, including Nautilus elliptical trainers, StairMaster products, and the Nitro, Nitro Plus, Studio, F2, XPLoad, and Nautilus One product lines (Compl. ¶¶ 19, 41).

Functionality and Market Context

  • The accused products are commercial-grade exercise machines designed for specific muscle groups, such as Biceps Curl, Lower Back, Leg Extension, and Pec Fly machines (Compl. ¶ 42). Each machine allegedly bears a "patent marking" label that lists numerous U.S. patent numbers (Compl. ¶ 42).
  • Plaintiffs allege these markings create a competitive injury by deterring them from designing and building their own rehabilitation equipment, as they were led to believe that the technology was "heavily protected by Nautilus patents" (Compl. ¶ 29). The markings allegedly caused the plaintiff to conclude that Nautilus was the "only source of suitable technology" (Compl. ¶ 30).

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

This section is not applicable as the complaint does not assert any patent claims.

VI. False Marking Allegations

The complaint alleges that Nautilus falsely marked its products with an intent to deceive the public, its competitors, and potential developers of related machines, in violation of 35 U.S.C. § 292 (Compl. ¶¶ 35, 48). The allegations are categorized as follows:

  • Marking with Expired Patents: The complaint repeatedly alleges that various product lines manufactured from 2006 through 2009 are marked with labels listing at least twelve to fourteen patents that had expired years before the products were made (Compl. ¶¶ 42-46). For example, the "2006 Nitro Plus Biceps Curl" is allegedly marked with U.S. Patent Nos. 3,858,873 and 3,998,454, which expired in 1992 and 1993, respectively (Compl. ¶ 42.a).
  • Marking with Unrelated Patents: The complaint alleges that products are marked with patents that "do not cover the product" (Compl. ¶ 39). For instance, various weight machines are allegedly marked with U.S. Patent No. 4,257,592, which is directed to a rope-and-handle exercising apparatus, a technology allegedly not used in the marked machines (Compl. ¶ 42.a). Similarly, U.S. Patent No. 4493485, directed to a method for monitoring physical effort, is allegedly marked on machines that do not perform this function (Compl. ¶ 42.a).
  • Marking with "Patents Pending": The complaint alleges that Nautilus marked products with the phrase "OTHER PATENTS PENDING" when, upon information and belief, no such patents were actually pending for those products (Compl. ¶¶ 39, 42).
  • Intent to Deceive: To satisfy the statute's intent requirement, the complaint alleges that Nautilus's knowledge of the falsity of its markings can be inferred from several facts:
    • Prior Adjudication: The complaint cites a 2006 jury verdict finding that Nautilus had falsely marked its Bowflex products "with the purpose of deceiving the public," arguing that this prior case put Nautilus on notice of its obligations under the false marking statute (Compl. ¶¶ 18, 49).
    • Litigation History: Nautilus's history of aggressively litigating its patents is presented as evidence that it knows "what its patents cover and when they expire" (Compl. ¶¶ 50-51).
    • Corporate Transactions: The complaint alleges that through due diligence in corporate acquisitions and the use of its patent portfolio as collateral for a $100,000,000 line of credit, Nautilus must have known the status and scope of its patents (Compl. ¶¶ 54-57).
    • SEC Filings: Public statements in SEC filings emphasizing the importance of its patent portfolio for maintaining its competitive position are cited as evidence of a motive to deter competitors through false marking (Compl. ¶¶ 20, 61-68).

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

This case will not turn on claim construction or technical infringement analysis, but rather on the specific elements of a false marking claim under 35 U.S.C. § 292. The central questions for the court appear to be:

  • A core issue will be one of factual verification: are the specific Nautilus products identified in the complaint, manufactured after 2006, actually marked with the lists of expired and allegedly unrelated patent numbers as claimed? This will require an examination of the products and their patent labels.
  • A key question will be one of statutory intent: assuming the markings are factually incorrect, can Plaintiffs prove that Nautilus acted with the specific "purpose of deceiving the public"? The complaint's reliance on the prior Icon Health verdict suggests this will be a central battleground, raising the question of whether continued marking after that verdict constitutes reckless or deliberate deception sufficient to meet the statutory standard.
