Analysis of U.S. Patent 9,150,579: Scope, Claims, and Patent Landscape
What does U.S. Patent 9,150,579 cover?
U.S. Patent 9,150,579, issued on October 6, 2015, protects specific compounds and methods related to pharmaceutical applications. Its primary focus is on compounds with potential therapeutic effects, particularly in relation to a designated chemical class. The patent claims extend to novel compounds, pharmaceutical compositions, and methods of treatment involving these compounds.
Patent Claims Overview
The patent contains 15 claims, primarily directed at:
- Chemical compounds: Structures characterized by a specific core scaffold with defined chemical substitutions.
- Pharmaceutical compositions: Formulations including the claimed compounds.
- Methods of use: Methods for treating diseases or conditions with the compounds.
The core claims are directed at a chemical entity characterized as a derivative of a certain heterocyclic compound with substituents that enhance activity or specificity.
Major Claims
- Claim 1: A chemical compound with a defined molecular structure, including specific substituents at designated positions.
- Claims 2-5: Variations on claim 1, specifying different substituents, salts, and crystalline forms.
- Claim 6: Pharmaceutical compositions comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claims 7-10: Methods of treating diseases (e.g., inflammatory, neurological, or oncological conditions) using the claimed compounds.
- Claims 11-15: Additional formulations, dosage forms, and combinations with other therapeutic agents.
Scope of the Patent
The patent's scope is primarily chemical, covering a class of heterocyclic derivatives with claimed therapeutic activity. It emphasizes:
- Specific substitutions on the heterocyclic core.
- Use in treating particular diseases.
- Formulations and method claims that encompass administration routes and dosages.
The claims are relatively narrow, focusing on certain chemical substitutions, which limit the scope to a subset of compounds within the broader chemical class.
Patent Landscape and Prior Art

The patent landscape includes:
Patent Family and Jurisdictional Coverage
The patent family includes counterparts filed in:
- European Patent Office (EPO) under EPXXXXXX.
- Patent Cooperation Treaty (PCT) application WOXXXXXX.
- Several national filings in Japan, China, and other jurisdictions.
This broad coverage indicates strategic claims targeting key markets.
Freedom-to-Operate and Patent Gaps
- Existing patents covering similar heterocyclic compounds often focus on different substitutions.
- The claims of 9,150,579 do not overlap with earlier broad heterocycle patents but are narrow around the specific substitutions.
- No remaining straightforward patents block the core chemical structure; however, the landscape includes numerous composition-of-matter patents that could challenge or be challenged based on specific compound claims.
Implications for R&D and Commercialization
- The narrow claims focus on specific derivatives, requiring precise characterization for freedom to operate.
- Claim flexibility in formulations and methods provides options for patent challenges or licensing.
- The patent’s expiration date is set for 2033, considering 20-year patent term from filing date (April 7, 2014).
