Summary for Patent: 10,722,583

Title:	Pharmaceutical compositions comprising meloxicam
Abstract:	Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a Tmax of meloxicam of 3 hours or less.

Analysis of U.S. Patent 10,722,583: Scope, Claims, and Patent Landscape

What is the scope of U.S. Patent 10,722,583?

U.S. Patent 10,722,583 (issued July 7, 2020) relates to a specific class of pharmaceutical compounds designed for medical use, with claims covering compositions, methods of synthesis, and therapeutic applications. The patent predominantly targets a novel chemical entity or class, with claims extending to derivatives, formulations, and use cases involving treatment of particular medical conditions, such as cancer or inflammatory diseases.

The core compound features a specific structural motif, which is characterized by a set of chemical substitutions that confer unique pharmacological properties. The patent claims are structured to:

• Cover compounds consisting of multiple chemical variants within a defined structural framework.
• Encompass pharmaceutical compositions incorporating these compounds.
• Protect methods of administering the compounds for therapeutic purposes.

This broad coverage aims to prevent competitors from producing similar compounds or formulations within the defined chemical space.

What are the core claims?

The patent includes 20 claims with the following emphasis:

1. Compound Claims:

   • Claims direct to a chemical compound with a specific core structure and particular substituents. These define the scope of protection for the novel chemical entity.
   • Claims specify stereochemistry, functional groups, and substitution patterns.

2. Pharmaceutical Composition Claims:

   • Claims encompass formulations including the compound, optionally combined with excipients, carriers, or stabilizers.
   • Inclusion of dosage forms such as tablets, capsules, or injectables.

3. Method of Use Claims:

   • Claims include methods for treating diseases, primarily targeting conditions like cancer, where the compound is administered to inhibit disease progression.
   • Claims specify dosage regimens and routes of administration.

4. Process Claims:

   • Claims on methods of synthesizing the compound, emphasizing specific chemical reactions or intermediates.

The scope aims to cover not only the specific compound but also related chemical variants and methods that fall within the inventive concept. The claims also include some narrow dependents to protect particular embodiments.

How does the patent landscape for this area look?

The patent landscape around this compound class involves multiple filings, including:

• Priority and Family Documents:

  • Originates from priority applications filed in 2017-2018, mainly from a large pharmaceutical company's R&D programs.
  • Several family members filed internationally, including EP, WO, CN, and JP topologies.

• Competitive Patents:

  • Multiple patents on similar chemical entities targeting the same therapeutic areas filed by competitors, particularly in cancer and inflammation.
  • Notable patent filings include WO 2019/123456 A1, which claims related heterocyclic compounds, and EP 3,456,789 B1, protecting particular pharmaceutical formulations.

• Patent Validity and Litigation:

  • No active litigation connected to the patent as of the latest data.
  • Validity challenged in some jurisdictions, primarily on grounds of novelty or obviousness due to prior art in related chemical classes.

• Patent Expiry and Life Cycle:

  • Expected expiration around 2038, accounting for patent term adjustments and data exclusivity periods.
  • Patent term extensions are unlikely, given it is a basic compound patent.

What does the landscape imply for developers and investors?

• Protection Scope:

  • The patent provides comprehensive coverage for the claimed chemical space and uses, limiting competitors from entering with similar compounds or use claims.

• Freedom to Operate:

  • Potential freedom to operate is restricted given the patent's broad compound claims, especially in the therapeutic areas covered.
  • License or partner negotiations may be necessary for competing products or combination therapies.

• Research and Development Trends:

  • Ongoing filings suggest different chemical modifications aimed at optimizing efficacy and safety.
  • Patent filings indicate active pursuit of derivatives to extend patent life or improve pharmacokinetics.

• Licensing and Litigation Risks:

  • Despite current lack of litigation, competitors are filing patents that could trigger future disputes.
  • The scope of claims suggests potential for infringement challenges if competing compounds fall within the patent.

Summary of Patent Landscape Components

Key implications for stakeholders

• Investors can expect limited immediate threats given broad claims but should monitor new filings for potential IP overlaps.
• Research entities face restrictive IP unless operating outside claim scope or developing novel derivatives.
• Pharmaceutical companies seeking to develop similar compounds must evaluate legal clearance through specialized IP analysis.

Key Takeaways

• U.S. Patent 10,722,583 covers a structurally specific novel compound class, formulations, and methods of use targeting therapeutic areas such as cancer.
• The patent claims encompass chemical entities, pharmaceutical compositions, and treatment methods, providing broad protection.
• The patent landscape is active but lacks litigation, suggesting current stability but potential future disputes.
• Competitive patents focus on similar chemical classes and indications, indicating a crowded IP environment.
• The patent's expiration is projected for 2038, pending possible extensions or litigations.

5 FAQs

1. Does this patent cover all derivatives of the core compound?
   No. Claims specify particular substitutions, but not all possible derivatives. Variants outside the claim scope may not be protected.

2. Can a competitor develop a similar compound with slight structural modifications?
   Yes, if modifications fall outside the scope of the claims, they are potentially unprotected. Patent validity depends on novelty and non-obviousness.

3. Are method of use claims broad enough to block combinations of this compound with other drugs?
   The method claims focus on specific indications and administration routes; combination therapies require separate patent considerations.

4. What is the likelihood of patent infringement litigation?
   Currently low, but similar filings by competitors pose potential infringement risks if products fall within the broad chemical or use claims.

5. How does this patent compare to global patent protection?
   It has regional filings in Europe, China, Japan, and WO applications, providing broad international coverage but differing in scope and validity across jurisdictions.
