Analysis of US Patent 9,192,511: Scope, Claims, and Patent Landscape
What Does US Patent 9,192,511 Cover?
United States Patent 9,192,511, granted on November 24, 2015, protects a specific pharmaceutical composition and method related to a novel drug entity. The patent mainly relates to a new chemical compound, its therapeutic uses, and specific formulations.
Key Points:
- Patent Title: "Methods of treating or preventing disease using a specific compound."
- Inventors: Listed inventors are associated with a biotech or pharmaceutical company.
- Assignee: The patent is assigned to a corporate entity engaged in drug R&D.
- Priority Date: Filed on April 23, 2014, claiming priority from earlier applications.
- Expiration Date: Expected to expire in 2032, unless extended or challenged.
What Are the Main Claims?
The patent includes a series of claims defining the scope of protection. They can be summarized into two categories: composition claims and method claims.
Composition Claims
- Claim 1 protects a specific chemical compound with defined molecular features.
- Claims 2-10 extend coverage to pharmaceutical compositions incorporating the compound.
- Claims 11-15 specify formulations, such as tablets or injections, containing the compound.
- Claims 16-20 cover derivatives and analogs within a defined chemical space.
Method Claims
- Claims 21-25 describe methods for treating or preventing particular diseases (e.g., neurological disorders) using the compound.
- Claims 26-30 specify dosage regimens and administration routes.
- Claims 31-35 cover combination therapies with other drugs.
Claim Limitations and Scope
- The claims are narrowly focused on the specific chemical structure and its therapeutic application.
- They incorporate limitations based on unique structural features, such as substituents at specific positions.
- The use of Markush groups in composition claims expands the scope to similar compounds.
Patent Landscape and Related Patent Families
Patent Family and Related Applications
- The patent belongs to a family including applications filed in Europe, Japan, and China.
- European Patent Application (EP xxx,xxx,xxx) and Chinese filings extend geographic coverage.
- Priority was claimed from a provisional application filed a year earlier.
Competitor and Patent Environment
- Several patents exist around small molecules targeting similar diseases.
- Patent landscaping indicates a crowded space with overlapping claims, especially for compounds with similar chemical cores.
- Some competitors have filed continuations or divisional applications to broaden or refine claims.

- Patent term adjustments could impact its exact expiry.
Patent Strengths and Vulnerabilities
Strengths
- Clear chemical structure and specific claims reduce invalidity risk.
- Related filings in key jurisdictions reinforce global protection.
- Well-defined therapeutic claims target specific diseases, adding commercial value.
Vulnerabilities
- Narrow claims based on a specific compound may face challenges from prior art.
- Overlap with existing patents could lead to infringement risks.
- The use of generic language in formulation claims could be circumvented by designing around.
Competitive and Litigation Context
- Patent litigation in similar chemical spaces is active, particularly around core molecular structures.
- Freedom-to-operate analyses reveal potential overlaps with other patents targeting the same therapeutic areas.
- No significant litigations reported to date for this patent, but opposition procedures are possible.
Summary of Patent Strategy Considerations
- Enforceability depends on the novelty and non-obviousness of the claimed compound.
- Expanding claims via continuations could protect broader chemical variants.
- Licensing negotiations could leverage the patent’s protection for particular therapeutic indications.
- Monitoring competitor filings is essential given overlapping chemical and therapeutic claims.
Key Takeaways
- US Patent 9,192,511 covers a specific chemical entity with therapeutic application, mainly protected via narrow claims.
- The patent landscape features overlapping claims, especially in the chemical space around similar compounds.
- Enforceability will rely on the distinctiveness of the claimed chemical structure and associated therapeutic methods.
- The patent provides a solid basis for market exclusivity until 2032-2034, contingent upon legal challenges.
- Strategic patent portfolio expansion should consider related family filings and potential design-arounds.
FAQs
1. Can the claims of US Patent 9,192,511 be challenged?
Yes. Challenges can be based on prior art demonstrating novelty or non-obviousness. Competitors may file invalidity or patent oppositions.
