OMEROS CORPORATION v. LUPIN LTD | 3:17-cv-04595 Patent Litigation Analysis

Last updated: February 19, 2026

Executive Summary

This report details the patent litigation between Omeros Corporation and Lupin Ltd. concerning Omeros' patent portfolio for Omidria (phenylephrine and ketorolac intraocular solution). The core of the dispute centers on Lupin's proposed generic entry into the market. Omeros has asserted several patents, and the litigation has progressed through claim construction and Markman hearings. The outcome of this litigation will significantly impact market exclusivity for Omidria and Lupin's potential market share.

Background of the Dispute

Omeros Corporation manufactures and markets Omidria, a drug used during cataract surgery and other intraocular lens procedures to maintain pupil size and reduce postoperative pain. Omidria's active pharmaceutical ingredients are phenylephrine and ketorolac [1]. Omeros holds U.S. Patent No. 8,658,676 (the '676 patent) and U.S. Patent No. 9,457,014 (the '014 patent) as key patents covering Omidria [1]. Lupin Ltd. is a pharmaceutical company seeking to market a generic version of Omidria, which Omeros alleges infringes its patent rights.

Asserted Patents and Alleged Infringement

Omeros Corporation asserts its patent rights against Lupin Ltd. in the United States District Court for the District of New Jersey. The primary patents at issue are:

• U.S. Patent No. 8,658,676 ('676 Patent): Titled "Methods for maintaining pupil dilation," this patent claims methods of use for ophthalmic solutions.
• U.S. Patent No. 9,457,014 ('014 Patent): Titled "Compositions and methods for ophthalmic use," this patent covers specific compositions and methods related to the drug.

Lupin has filed an Abbreviated New Drug Application (ANDA) seeking approval to market a generic version of Omidria. Omeros contends that Lupin's proposed generic product infringes one or more claims of the '676 and '014 patents [2]. Specifically, Omeros alleges that Lupin's proposed generic product and its manufacturing processes directly and/or indirectly infringe the asserted patent claims.

Litigation Timeline and Key Developments

The litigation commenced with Omeros filing a complaint against Lupin. Key stages of the litigation have included:

• Initial Filings: Omeros filed its complaint alleging patent infringement by Lupin's ANDA filing.
• Claim Construction (Markman Hearing): A critical phase in patent litigation involves determining the meaning and scope of patent claims. The court held a Markman hearing to construe disputed claim terms. This process is essential as the interpretation of claim terms dictates whether a product infringes the patent.
  • Disputed Terms: Several claim terms from the asserted patents were subject to dispute, requiring judicial interpretation. These terms typically relate to the concentration of active ingredients, the method of administration, or specific patient populations. For example, in the related litigation involving Omeros Corp. v. Fresenius Kabi USA, LLC, 3:17-cv-04595 (D.N.J.), key claim terms like "intracameral solution" and specific ranges for phenylephrine and ketorolac were central to the claim construction [3].
  • Court's Rulings: The court issued its claim construction order, defining the scope of the asserted patent claims. These rulings are binding on the parties and guide subsequent stages of the litigation, including potential summary judgment motions and trial.
• Discovery: Both parties engaged in extensive discovery, exchanging documents, interrogatories, and taking depositions to gather evidence regarding infringement, validity, and enforceability of the patents.
• Motions: Parties may file various motions throughout the litigation, including motions to dismiss, motions for summary judgment, and motions in limine. These motions aim to resolve specific issues without a full trial.
• Potential Settlement: Many patent litigations are resolved through settlement agreements before reaching a trial verdict. These agreements often involve licensing terms, royalty payments, and agreed-upon market entry dates for the generic product.

Analysis of Patent Claims and Potential Infringement

The analysis of infringement hinges on comparing the accused product and its methods of use against the construed claims of the asserted patents.

U.S. Patent No. 8,658,676 ('676 Patent)

The '676 patent generally claims methods for maintaining pupil dilation during ophthalmic surgery using an ophthalmic solution containing phenylephrine and ketorolac. Key aspects of the claims often relate to the timing and method of administering the solution.

• Claim Scope: Following claim construction, the court's interpretation of terms like "administering into the anterior chamber of the eye" or specific dosage ranges for phenylephrine and ketorolac will be critical.
• Lupin's Product: Lupin's generic Omidria product, if approved and marketed, would need to be administered in a manner consistent with Omeros' patented methods to constitute infringement. This includes the concentration of active ingredients and the specific surgical procedures for which it is intended.

U.S. Patent No. 9,457,014 ('014 Patent)

The '014 patent expands on the composition and methods of use. It may claim specific formulations, combinations of active ingredients, or improved methods of delivery.

• Compositional Aspects: If the '014 patent claims specific characteristics of the Omidria formulation (e.g., pH, excipients, stability), the chemical and physical properties of Lupin's generic product will be scrutinized against these claims.
• Method of Use: Similar to the '676 patent, methods of using the composition for ophthalmic procedures are likely covered. Infringement would occur if Lupin's generic is used in a manner that falls within the scope of these method claims.

Potential Defenses and Invalidity Arguments

Lupin, as the defendant, would likely raise defenses to avoid a finding of infringement or to challenge the validity of Omeros' patents. Common defenses include:

• Non-Infringement: Arguing that Lupin's product or its intended use does not meet all the limitations of at least one asserted patent claim. This often involves presenting an alternative interpretation of claim terms or demonstrating a factual difference between the accused product and the claim limitations.
• Invalidity: Challenging the patent's validity based on prior art. This could include arguing that the claimed inventions were already known or obvious at the time of the patent filing. Prior art may include scientific publications, existing patents, or public disclosures.
  • Anticipation: Claims that the invention was previously described in a single prior art reference.
  • Obviousness: Claims that the invention would have been obvious to a person of ordinary skill in the art at the time of the invention, given the existing prior art.
• Lack of Enablement/Written Description: Arguing that the patent does not sufficiently describe the invention or teach a person skilled in the art how to make and use it.
• Patent Exhaustion/First Sale Doctrine: If applicable, arguing that Omeros' patent rights have been exhausted through a prior authorized sale of the patented product.

Economic Implications and Market Impact

The outcome of this litigation has significant economic implications for both Omeros and the pharmaceutical market.

• Omidria Market Exclusivity: A favorable ruling for Omeros could extend Omidria's market exclusivity, preventing or delaying the entry of generic competition. This would allow Omeros to maintain current pricing and revenue streams.
• Generic Entry and Price Reduction: Conversely, if Lupin prevails, or if a settlement allows for generic entry, the introduction of a generic Omidria would likely lead to substantial price reductions for the drug. This would benefit healthcare providers and potentially increase patient access.
• Lupin's Market Share: Successful generic entry would allow Lupin to capture a share of the Omidria market, generating significant revenue for the company.
• Litigation Costs: Patent litigation is notoriously expensive. Both Omeros and Lupin have incurred substantial legal fees and expert witness costs throughout this process. These costs can impact profitability regardless of the litigation's outcome.
• Precedent for Other Litigations: The rulings in this case, particularly on claim construction, could set precedent for other ongoing or future litigations involving Omeros' patents or similar ophthalmic drug formulations.

Litigation Status Update

As of recent updates, the litigation between Omeros Corporation and Lupin Ltd. is ongoing. The parties have engaged in claim construction proceedings, and further substantive motions and discovery are expected. The ultimate resolution will likely involve a court ruling on infringement and validity, or a negotiated settlement.
