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

U.S. Patent No. 4,869,049 - "APPARATUS AND METHODS FOR USING PACKS OF FLEXIBLE TUBING IN PACKAGING" (Issued Sep. 26, 1989)

  • The Invention Explained:
    • Problem Addressed: The patent's background section describes the need for a hygienic, convenient, and "smell-free" method for disposing of babies' disposable diapers, a common problem for caregivers ('049 Patent, col. 1:15-24).
    • The Patented Solution: The invention is a mechanical apparatus that uses a continuous tube of flexible plastic film. A soiled diaper is pushed through a guide into the tubing. A mechanism above the guide is then manually rotated to twist the tubing, which seals the diaper in an individual, odor-contained package and simultaneously prepares the next section of tubing for use ('049 Patent, Abstract; col. 2:14-24). The general operation is depicted in Figure 1, which shows an object (35) being pushed into the tubing (2) and a twist (30) being formed to create a chain of sealed packages (36).
    • Technical Importance: The technology provided a non-electric, comparatively simple, and portable solution for in-home disposal of soiled waste, addressing a significant need in the large market for disposable diapers ('049 Patent, col. 1:51-54).
  • Key Claims at a Glance:
    • The complaint makes general allegations that the patent is inapplicable and does not assert specific claims (Compl. ¶¶28, 35). Independent claim 1 is representative and includes the following essential elements:
      • Tubular guide means arranged to receive a pack of tubing.
      • A structure enabling the tubing to be drawn from the pack, closed at one end to form a base, and passed through the guide means.
      • A stationary support for the tubular guide means, which includes an opening for the passage of a completed package.
      • Manually rotatable means mounted for rotation relative to the support for engaging and twisting the tubing to complete a package.

U.S. Patent No. 4,934,529 - "CASSETTE CONTAINING FLEXIBLE TUBING TO BE DISPENSED THEREFROM" (Issued Jun. 19, 1990)

  • The Invention Explained:
    • Problem Addressed: The patent identifies the need for a convenient and compact method of supplying and replacing the flexible tubing used in packaging apparatus, such as the one described in the '049 Patent ('529 Patent, col. 1:9-13).
    • The Patented Solution: The invention is a self-contained, disposable cassette. It consists of a rigid body with a central core and a surrounding casing, with a long length of flexible tubing packed into the annular space between them. An annular cap holds the packed tubing in place, and detent means on the casing prevent the cap from being unintentionally dislodged ('529 Patent, Abstract; col. 2:4-10). The structure allows the cassette to be easily inserted into a compatible disposal device as a refill.
    • Technical Importance: The invention created a user-friendly, mass-producible refill system that enabled the long-term, continuous use of the primary disposal apparatus by consumers ('529 Patent, col. 1:9-17).
  • Key Claims at a Glance:
    • The complaint makes general allegations that the patent is inapplicable (Compl. ¶¶28, 35). Independent claim 1 is representative and includes the following essential elements:
      • A rigid body comprising a central tubular core and a surrounding casing wall.
      • A length of non-resilient flexible tubing packed in a layered mass in the annular space between the core and casing.
      • An annular cap placed over the pack of tubing.
      • Detent means integral with the casing wall that projects inwards to engage the cap and limit its upward movement.

Multi-Patent Capsule

  • Patent Identification: U.S. Patent No. 5,056,293, "APPARATUS FOR PRODUCING LAYERED TUBES OR RINGS," Issued Oct. 15, 1991.
  • Technology Synopsis: This patent describes an industrial-scale machine, not a consumer product. The apparatus is for manufacturing the refill cassettes by automatically feeding, gathering, and compacting flexible tubing into an annular container ('293 Patent, Abstract).
  • Asserted Claims: The complaint makes general allegations that the patent is inapplicable to the marked product (Compl. ¶19(j), ¶28). Independent claim 1 is representative.
  • Accused Features: The "Playtex® Diaper Genie® Twistaway® Disposal System Refill" is accused of being falsely marked with the '293 Patent (Compl. ¶19(j)).

III. The Accused Instrumentality

  • Product Identification: The complaint identifies the "Playtex® Diaper Genie® Twistaway® Disposal System" and the "Playtex® Diaper Genie® Twistaway® Disposal System Refill" (Compl. ¶19(j), 19(m)).
  • Functionality and Market Context: The complaint identifies the accused products by their brand names but does not provide a technical description of their specific features or operation (Compl. ¶19). It alleges that by marking the products, Defendants have wrongfully advertised patent monopolies and benefited by maintaining a substantial market share (Compl. ¶27).

IV. Analysis of False Marking Allegations

The complaint does not provide an element-by-element analysis of how the accused products are covered or not covered by the patent claims. Instead, it advances a broader theory that the patents are inapplicable primarily because they are expired or, in some cases, directed to subject matter different from the marked product (Compl. ¶¶19(r), 28, 30).

A central allegation is that Defendants have marked products with patent numbers that were expired at the time of marking (Compl. ¶¶29-30). U.S. utility patents issued from applications filed before June 8, 1995, generally have a term of 17 years from the issue date or 20 years from the earliest effective filing date, whichever is longer. The '049 Patent, issued September 26, 1989, and the '529 Patent, issued June 19, 1990, were expired by the time the March 18, 2011 complaint was filed. The complaint alleges that marking continued on these unpatented articles with an intent to deceive the public (Compl. ¶¶32, 35, 36).

For other patents, such as the '293 Patent, the allegation of inapplicability may rest on a question of scope. The '293 Patent claims an "apparatus for producing" the refills, not the refill product itself ('293 Patent, Abstract; Claim 1). The complaint alleges that marking the refill with this patent number is improper because a patent on a manufacturing method or machine does not cover the resulting product sold to consumers (Compl. ¶19(j), ¶35).

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

Because the primary allegation is that patents are expired, claim construction may not be the central issue for many of the patents. However, for patents where the scope is disputed, such as the '293 patent, the interpretation of certain terms may be critical.

  • The Term: "Apparatus for producing layered tubes or rings" ('293 Patent, Claim 1 Preamble)
  • Context and Importance: The construction of this preamble term is fundamental to determining whether the '293 patent "covers" the accused refill cassette. Practitioners may focus on this term because the accused instrumentality is the product made by the claimed apparatus, not the apparatus itself. The dispute raises the question of whether marking a product with a patent for the machine that manufactures it constitutes false marking.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: A party might argue that the term "covers" in the marking statute should be interpreted broadly. The specification explicitly links the apparatus to its output, stating it is for packing tubing into a "container constituting the body 20 of a cassette as particularly described in applicant's co-pending British Patent Application" ('293 Patent, col. 2:17-21). This could be used to suggest that the product is integral to the identity of the patented invention.
    • Evidence for a Narrower Interpretation: The claim language itself is directed to an "apparatus," and its elements recite machine components: "a layering tube," "a central mandrel," "means for feeding flexible, non-resilient tubing," and "reciprocable means... for compacting the tubing" ('293 Patent, Claim 1). This language may support the view that the patent's legal scope is confined strictly to the manufacturing machine and does not extend to the articles it produces.

VI. Allegations of Deceptive Intent

  • Willful Infringement: The complaint alleges that Defendants' false marking was performed with the "purpose of deceiving the public" (Compl. ¶19), which is the statutory element of intent required under 35 U.S.C. § 292. The basis for this allegation includes the assertions that Defendants are "large, sophisticated" companies, regularly retain legal counsel, and have experience in patent matters (Compl. ¶¶22-24). The complaint further alleges that Defendants knew the patents were expired or inapplicable at the time they were marked on the products and therefore "intentionally deceived the public" (Compl. ¶33).

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

  • A core issue will be evidentiary: Can the Plaintiff establish not only that Defendants marked products with expired or inapplicable patent numbers, but that this was done with the specific "purpose of deceiving the public" as required by 35 U.S.C. § 292, rather than through oversight or mistake?
  • A key legal question will be one of statutory scope: For patents directed to manufacturing equipment, such as the '293 patent, the court may need to decide whether a patent claiming an "apparatus for producing" an article can be considered to "cover" the resulting article for purposes of the patent marking statute.
