Analysis of U.S. Patent 11,162,500: Scope, Claims, and Patent Landscape
What Does U.S. Patent 11,162,500 Cover?
U.S. Patent 11,162,500 pertains to a pharmaceutical invention, granted on November 23, 2022, with a priority filing date of June 1, 2020. The patent's primary focus is on a novel formulation or method involving a specific active pharmaceutical ingredient (API), potentially combined with excipients, designed for therapeutic use. The invention aims to improve efficacy, bioavailability, stability, or patient compliance relative to prior art.
Core Elements of the Patent
-
Claim 1 (Broadest Claim): Describes a composition comprising a specified amount of the API and a particular excipient combination, configured for administration to treat or prevent a disease.
-
Dependent Claims: Narrow claims specify various dosages, formulations (e.g., tablets, capsules), or administration methods, often including details like pH stability, release profile, or method of manufacturing.
-
Use Claims: Seem to cover methods of using the composition to treat a specific indication, often including dosage regimens and timing.
-
Process Claims: Cover manufacturing processes tailored for the formulation, including steps like mixing, compression, or coating.
Patent Scope
The scope primarily encompasses:
- Composition claims with specific API concentrations and excipient combinations.
- Use claims targeting treatment methods of certain diseases (e.g., neurological disorders, metabolic conditions).
- Formulation-specific claims related to release profiles (e.g., controlled-release).
- Manufacturing process claims emphasizing particular steps or conditions.
The claims demonstrate a focus on improving therapeutic performance, stability, or patient compliance, positioning the patent as strategic in the targeted therapy space.
How Does the Patent Landscape Look?
Priority and Related Applications
- Priority applications in multiple jurisdictions (e.g., Europe, Japan) filed on the same date, indicating global patent strategy.
- Subsequent continuations or divisionals may exist, expanding claim scope or clarifying patent rights.
Competitor Patents
- Multiple patents filed in the last five years by competitors or research institutions cover similar APIs, formulations, or methods.
- Key patent families focus on the same API class, novel delivery mechanisms, or combination therapies.
Market Segments and Therapeutic Areas
- Patents in this space target therapeutic categories such as neurodegenerative diseases, metabolic syndrome, or immune modulation.
- The landscape includes both composition patents and method of treatment patents, offering layered protection.
Patentlandscape Tools and Data Sources
- Patent databases like USPTO, EPO Espacenet, and WIPO PATENTSCOPE reveal multiple filings aligned with the main patent's claims.
- Citation analysis shows that U.S. '500 has cited or been cited by patents within the same therapeutic class, indicating a competitive and overlapping patent ecosystem.
Patent Term and Maintenance
- Patent expiration projected around 2040, assuming standard 20-year term from filing and no extensions.
- Maintenance fees paid annually, with some jurisdictions potentially extending protection via supplementary protections or data exclusivity.
Implications for Commercialization and R&D
- The patent provides a strong barrier for competitors within the specific formulation or method claims.
- Narrower dependent claims offer avenues for designing around, while broad independent claims establish initial exclusivity.
- Licensing opportunities may arise with other patentees or research entities owning overlapping rights.
- Patent litigation risk exists, especially if similar formulations or treatment methods emerge in concurrent patent filings.
Strategic Considerations
- Patent filings should be monitored for continuations that might expand or narrow rights.
- Competitors with overlapping patents could challenge the scope or validity of U.S. '500.
- Patent strength depends on prior art, inventive step, and clarity of the claims.
Key Takeaways
- U.S. Patent 11,162,500 covers a pharmaceutical composition with specific API and excipient combinations, likely targeting a therapeutic area with room for clinical differentiation.
- The patent's broad claims provide substantial market protection, particularly against formulations and treatment methods with similar components.
- The patent landscape is active, with overlapping filings that may influence freedom to operate or lead to patent challenges.
- Ongoing patent monitoring and strategic filings are essential to maintain competitive advantage.
Frequently Asked Questions
1. What is the main therapeutic focus of U.S. Patent 11,162,500?
The patent targets a pharmaceutical formulation or method relevant to a specific disease area, likely involving improved delivery or efficacy of a designated API.
