II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 6,797,289 - "Use of Anabolic Agents, Anti-Catabolic Agents, Antioxidant Agents, and Analgesics for Protection, Treatment and Repair of Connective Tissues in Humans and Animals"
- Patent Identification: U.S. Patent No. 6,797,289, "Use of Anabolic Agents, Anti-Catabolic Agents, Antioxidant Agents, and Analgesics for Protection, Treatment and Repair of Connective Tissues in Humans and Animals," issued September 28, 2004.
The Invention Explained
- Problem Addressed: The patent describes the natural balance in mammals between anabolic processes that build tissue and catabolic processes that degrade it (’289 Patent, col. 1:37-43). It notes that while inflammation is part of the healing process, common anti-inflammatory drugs can interfere with this repair, and that "subclinical" deficiencies of certain biochemicals can tip the balance toward tissue degradation (’289 Patent, col. 1:56-2:2, col. 1:47-54).
- The Patented Solution: The invention proposes compositions that combine different classes of agents (anabolic, anti-catabolic, antioxidant) to work together to promote healing and protect connective tissue (’289 Patent, col. 5:16-24). Specifically, it describes combining aminosugars (such as glucosamine) with avocado/soybean unsaponifiables (ASUs) to achieve a synergistic therapeutic effect (’289 Patent, Abstract).
- Technical Importance: The patent sought to protect specific combinations of nutraceuticals based on the theory that their combined effect on the cellular mechanisms of tissue repair is greater than their individual effects (’289 Patent, col. 12:63-67).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶31).
- Essential elements of claim 1:
- A composition for the treatment, repair or prevention of damage to connective tissue comprising:
- a synergistic combination of an aminosugar and avocado/soybean unsaponifiables.
- The complaint reserves the right to assert additional claims (’289 Patent, Compl. ¶30).
U.S. Patent No. 8,753,697 - "Use of Anabolic Agents, Anti-Catabolic Agents, Antioxidant Agents, and Analgesics for Protection, Treatment and Repair of Connective Tissues in Humans and Animals"
- Patent Identification: U.S. Patent No. 8,753,697, "Use of Anabolic Agents, Anti-Catabolic Agents, Antioxidant Agents, and Analgesics for Protection, Treatment and Repair of Connective Tissues in Humans and Animals," issued June 17, 2014.
The Invention Explained
- Problem Addressed: The ’697 Patent addresses the same technical problem as the ’289 Patent: maintaining the balance of anabolic and catabolic processes in connective tissues, which can be disrupted by aging, injury, and certain drug therapies (’697 Patent, col. 1:41-48, col. 1:56-2:5).
- The Patented Solution: The invention claims compositions combining avocado/soybean unsaponifiables (ASU) with a glycosaminoglycan (GAG), such as chondroitin sulfate, in "synergistically effective amounts" to protect and repair connective tissues (’697 Patent, Abstract; col. 5:46-58). The patent posits that these agents act on different cellular pathways to achieve a combined, enhanced effect (’697 Patent, col. 11:42-65).
- Technical Importance: This patent, like its family member, focuses on protecting specific combinations of ingredients that allegedly work synergistically to manage joint health, in this case focusing on the ASU and GAG pairing.
Key Claims at a Glance
- The complaint asserts independent claims 1 and 21 (Compl. ¶¶38, 46).
- Essential elements of claim 1:
- A composition comprising avocado/soybean unsaponifiables (ASU) and a glycosaminoglycan,
- wherein the ASU and the glycosaminoglycan are present in a synergistically effective amounts.
- Essential elements of claim 21:
- A method of treating or repairing damage to connective tissue in humans and animals comprising
- administering a composition according to claim 1 to a human or animal in need thereof.
- The complaint reserves the right to assert additional claims of the ’697 Patent (Compl. ¶37).
III. The Accused Instrumentality
Product Identification
- The accused product is Defendant’s "Joint Complete" nutritional supplement (Compl. ¶16).
Functionality and Market Context
- The Joint Complete product is a formulation sold for the improvement of joint health (Compl. ¶13). The complaint includes the "SUPPLEMENT FACTS" label for the accused product, which enumerates the allegedly infringing ingredients and their dosages per serving (Compl. p. 8). Per the label, a three-tablet serving contains, among other ingredients, 1500 mg of Glucosamine Sulfate, 150 mg of Chondroitin Sulfate USP, 15 mg of Hyaluronic Acid, and 300 mg of AvoVida™, which is identified as "Avocado/Soy Unsaponifiables" (Compl. ¶¶18-19, p. 8).
- The product is advertised with claims that it uses "nutritional building blocks for joints" and is "clinically proven to benefit joint health" (Compl. ¶17, Ex. C, D). Defendant allegedly sells the product directly through its website and indirectly through Amazon.com (Compl. ¶16).

Identified Points of Contention
- Technical and Evidentiary Question: A central issue will be the meaning of "synergistic combination" and "synergistically effective amounts." The complaint alleges synergy, but the case may turn on what type and level of evidence (e.g., in vitro studies, animal models, human clinical trials) is required to prove that the specific formulation of the Joint Complete product actually produces an effect greater than the additive effects of its components.
- Scope Question: The infringement reading of the ’697 Patent relies on both chondroitin sulfate and hyaluronic acid qualifying as "a glycosaminoglycan." While the patent specification lists both as examples, a potential question for the court is whether the presence of multiple GAGs affects the analysis of the claim, which is written in the singular ("a glycosaminoglycan").
V. Key Claim Terms for Construction
The Term: "synergistic combination" (’289 Patent) / "synergistically effective amounts" (’697 Patent)
Context and Importance: This is the central limitation in the asserted claims of both patents. Infringement requires not merely showing that the accused product contains the listed ingredients, but that they are combined in a way that produces a synergistic, or greater-than-additive, therapeutic effect. The entire infringement case rests on the construction and proof of this concept.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patents describe synergy in broad, functional terms, suggesting that different agents acting on different cellular pathways will produce a synergistic effect, without being limited to specific ratios or quantitative outcomes. For example, the specification states, "Because the different compounds of the present invention act on different cytokines, they will have synergistic effects when used in appropriate combinations" (’289 Patent, col. 12:63-67). This may support a construction not tied to the specific results shown in the patent's examples.
- Evidence for a Narrower Interpretation: The patents provide specific examples of experiments allegedly demonstrating a "novel interaction" or a "cartilage modulating effect" (’289 Patent, col. 18:18-21). A defendant may argue that these examples define the scope and type of synergy required by the claims, potentially limiting the term to a specific, demonstrable biochemical outcome.
The Term: "aminosugar" (’289 Patent)
Context and Importance: The infringement theory for the ’289 Patent depends on the "Glucosamine Sulfate" in the accused product falling within the patent’s definition of "aminosugar."
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification explicitly lists "salts of glucosamine including glucosamine hydrochloride and glucosamine sulfate" as falling within the scope of the term "aminosugar" (’289 Patent, col. 5:40-43). This provides direct support for the plaintiff's infringement theory.
- Evidence for a Narrower Interpretation: While appearing straightforward, a defendant could scrutinize the prosecution history (not provided in the complaint) for any disclaimers or definitions that might have narrowed the scope of the term during examination.
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement of infringement of at least claim 21 of the ’697 Patent. This claim is a method of treatment. The allegation is based on Defendant instructing and encouraging customers, through its website, advertising, and product instructions, to use the Joint Complete product for joint health, thereby performing the steps of the claimed method (Compl. ¶¶44-48).
- Willful Infringement: The complaint alleges that Defendant’s infringement has been and continues to be willful. The basis for this allegation is Defendant’s alleged continued infringement after receiving two pre-suit letters, dated September 10, 2018, and October 4, 2018, providing actual notice of the Asserted Patents (Compl. ¶¶28, 35, 42).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of evidentiary proof: What evidence will be sufficient to demonstrate that the specific combination of ingredients in the "Joint Complete" product achieves the "synergy" required by the patent claims? This will likely be a central battleground for expert testimony.
- A key legal question will be one of claim scope: How will the court construe the term "synergistically effective amounts"? The case's outcome may depend on whether this term is interpreted broadly based on the functional descriptions in the specification or more narrowly based on the specific experimental examples provided in the patents.
- A third pivotal issue concerns willfulness: Given the complaint's specific allegations of pre-suit notice, a central question for the court will be whether Defendant's continued sales after being notified constitute objective recklessness, potentially exposing Defendant to enhanced damages.
