II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,115,078: "Compositions for Improving the Quality of the Meibum Composition of Inflamed or Dysfunctional Meibomian Glands" (Issued Aug. 25, 2015)
The Invention Explained
- Problem Addressed: The patent addresses meibomian gland dysfunction, a condition where glands in the eyelids produce poor-quality, thickened oil (meibum). This meibum is described as being pro-inflammatory due to a high concentration of omega-6 fatty acids, leading to tear film instability, rapid tear evaporation, and chronic dry eye symptoms (’078 Patent, col. 1:43-54). Existing treatments are identified as providing only temporary relief without addressing the underlying oil composition (’078 Patent, col. 2:31-34).
- The Patented Solution: The invention is a nutritional composition designed to be orally administered to a patient. The composition provides a high dose of omega-3 fatty acids in a specific chemical form (triglyceride) intended to systemically alter and normalize the lipid profile of the meibum produced by the glands, thereby improving the function of the tear film's lipid layer (’078 Patent, col. 2:51-59).
- Technical Importance: The claimed invention represented a therapeutic strategy aimed at correcting the biochemical basis of a specific type of dry eye disease, rather than merely palliating its symptoms with topical treatments like artificial tears (’078 Patent, col. 1:19-24).
Key Claims at a Glance
- The complaint asserts infringement of one or more claims of the ’078 Patent (Compl. ¶30). The core allegations track the language of independent claim 1.
- Independent Claim 1:
- A composition consisting of a single fatty acid for improving the quality of the meibum composition of inflamed or dysfunctional meibomian glands,
- wherein said fatty acid consists of omega-3 fatty acids in the triglyceride form
- in an amount greater than 600 mg.
U.S. Patent No. 9,381,183: "Methods for Improving the Quality of the Meibum Composition of Meibomian Glands" (Issued Jul. 5, 2016)
The Invention Explained
- Problem Addressed: As with its parent patent, the ’183 Patent targets meibomian gland dysfunction where the glands produce pro-inflammatory meibum, leading to chronic dry eye (’183 Patent, col. 2:5-15).
- The Patented Solution: The patent claims a method of improving meibum quality. The method involves administering a specific omega-3 composition to a mammal, which is claimed to cause two distinct physiological effects: an increase in the level of anti-inflammatory omega-3 fatty acids within the meibum and a corresponding decrease in the level of pro-inflammatory omega-6 fatty acids (’183 Patent, Abstract; col. 21:24-38). This rebalancing is asserted to normalize the tear film.
- Technical Importance: This patent protects the therapeutic method and its specific, claimed biological outcomes (the shifting ratio of omega-3 to omega-6 in meibum), offering a different and potentially broader scope of enforcement than a pure composition patent (’183 Patent, col. 4:32-40).
Key Claims at a Glance
- The complaint asserts infringement of one or more claims of the ’183 Patent (Compl. ¶43). The core allegations track the language of independent claim 1.
- Independent Claim 1:
- A method for improving the quality of the meibum composition of inflamed or dysfunctional meibomian glands, comprising the steps of:
- administering a composition consisting of an effective amount of omega-3 fatty acids on a daily dosage basis to a mammal having inflamed or dysfunctional meibomian glands,
- wherein said omega-3 fatty acids includes eicosapentaenoic acid (EPA) in an amount greater than 600 mg and comprising the triglyceride form;
- increasing levels of anti-inflammatory omega-3's in a composition of meibum of said treated meibomian glands; and
- decreasing levels of inflammatory omega-6's in said composition of meibum.
III. The Accused Instrumentality
Product Identification
The accused product is the "Oasis TEARS OMEGA 3™ Dietary Supplement" (Compl. ¶19).
Functionality and Market Context
The complaint alleges the accused product is an oral dietary supplement formulated with omega-3 fatty acids and is marketed to eye care professionals and consumers for the purpose of reducing symptoms associated with dry eye (Compl. ¶41). The complaint alleges the product's formulation includes 1,714 mg of EPA and 1,289 mg of DHA per serving, delivered in triglyceride form (Compl. ¶30). The complaint includes a screenshot from Defendant’s website that allegedly markets the product for addressing conditions associated with dry eye (Compl. ¶39; Ex. D). Plaintiff asserts that Defendant is a direct competitor in the dry eye market and is marketing its product to the same target audience for the same purposes as Plaintiff's patented products (Compl. ¶¶19, 41).

Identified Points of Contention
- Scope Questions: A primary dispute regarding the ’078 Patent will likely involve the claim term "consisting of a single fatty acid." The phrase "consisting of" is typically interpreted as closed, meaning no other components are present. The question for the court will be whether a composition containing multiple distinct omega-3 fatty acids (e.g., EPA and DHA) can meet a limitation requiring a "single fatty acid."
- Technical Questions: For the ’183 Patent, infringement requires proving that the administration of the accused product actually causes the claimed physiological results ("increasing levels of...omega-3's" and "decreasing levels of...omega-6's" in the meibum). A key question will be what evidence Plaintiff can adduce to show that the accused method, as induced by Defendant, necessarily achieves these specific biological outcomes in end-users.
V. Key Claim Terms for Construction
The Term: "composition consisting of a single fatty acid" (’078 Patent, Claim 1)
- Context and Importance: This term appears to be the most restrictive and potentially dispositive limitation in the asserted composition claim. Its construction will determine whether a product containing a mixture of different omega-3 molecules (such as EPA and DHA) can infringe. Practitioners may focus on this term because the restrictive "consisting of" language presents a significant hurdle for the plaintiff.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The complaint does not present a basis for a broader interpretation. A party might argue "single fatty acid" refers to a singular type or class of ingredient (i.e., the omega-3 fatty acid component) rather than one molecular species, but this is not explicitly supported by the specification.
- Evidence for a Narrower Interpretation: The plain meaning of "consisting of" creates a strong presumption that the composition includes only the recited element. The term "a single fatty acid" further suggests singularity. The patent’s Certificate of Correction, which changes "Fatty" to "fatty," reinforces a focus on the precise wording but does not alter this fundamental question (’078 Patent, Cert. of Correction).
The Term: "increasing levels of anti-inflammatory omega-3's in a composition of meibum" (’183 Patent, Claim 1)
- Context and Importance: This is a result-oriented process step. Its interpretation is critical because it defines what must be proven to show infringement of the method. The dispute will center on whether infringement occurs by performing an act intended to cause this result, or only if the result is actually achieved.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent's objective is to provide a method that produces this effect. Plaintiff may argue that performing the "administering" step as directed necessarily results in "increasing levels," thus the steps are inextricably linked.
- Evidence for a Narrower Interpretation: The claim is written as a series of distinct steps connected by "and." This structure suggests that each step, including the "increasing levels" and "decreasing levels" steps, must be performed for infringement to occur. The specification describes clinical studies where these physiological changes were measured, suggesting the patent contemplates these as measurable, required outcomes of the method (’183 Patent, Tables 1-2, col. 7-9).
VI. Other Allegations
- Indirect Infringement: The complaint alleges both contributory and induced infringement (Compl. ¶¶ 21, 31). For the ’183 method patent, inducement is specifically alleged based on Defendant’s marketing of the accused product to professionals and consumers for dry eye treatment, which allegedly encourages and instructs them to perform the steps of the patented method (Compl. ¶¶ 41, 43).
- Willful Infringement: The complaint alleges that infringement has been willful and deliberate, citing alleged "discussions between Oasis Medical and PRN prior to Oasis Medical introducing its infringing 'Oasis TEARS OMEGA 3™ Dietary Supplement' product" as evidence of pre-suit knowledge of the asserted patents (Compl. ¶¶ 33, 45).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim construction: can the highly restrictive phrase "composition consisting of a single fatty acid" in the ’078 patent be interpreted to read on a product that, according to the complaint, contains a mixture of at least two different omega-3 fatty acids (EPA and DHA)? The outcome of this construction may be dispositive for infringement of the ’078 patent.
- A second central issue will be one of proof of infringement: for the ’183 method patent, what is the evidentiary standard to prove that the accused method, as practiced by end-users, achieves the claimed physiological results of "increasing levels of...omega-3's" and "decreasing levels of...omega-6's" in the patient's meibum? This question will determine the feasibility of proving both direct and induced infringement of the method claims.
