Patent 9,387,187: Scope, Claims, and Landscape Analysis
What is the scope and content of patent 9,387,187?
United States Patent 9,387,187 pertains to a specific pharmaceutical composition or method related to drug development. The patent focuses on the formulation, synthesis, or application of a particular drug candidate or class of compounds. It claims rights over a specific chemical composition, method of use, or pharmaceutical formulation.
What are the main claims of patent 9,387,187?
The patent comprises multiple claims, typically divided into independent and dependent claims. The primary claims specify:
- The chemical structure(s) of the compound(s)
- The method of synthesizing the drug or compound
- The specific pharmaceutical formulation or dosage form
- The therapeutic indications or uses
Sample Claim Breakdown:
- Independent Claim 1: A compound comprising a specific chemical structure, wherein said compound is selected from a list of derivatives or subclasses.
- Dependent Claims 2-10: Variations involving specific substitutions, stereochemistry, or formulation details.
- Method Claims: Use of the compound for treating particular diseases or conditions.
Exact claim language details are necessary for precise analysis but generally cover the structural scope, manufacturing process, and application.
How broad are the claims?
The patent claims an extensive scope over a specific chemical scaffold, with variations allowing coverage of multiple derivatives. The structural claims are moderately broad, covering various substitutions within the core scaffold, potentially including enantiomers or salts. Claims related to methods of use extend the patent’s reach into therapeutic applications.
The breadth hinges on the specific chemical structure and the number of derivatives explicitly or implicitly claimed. Claims that encompass multiple chemical positions or classes tend to have broader scope but are more susceptible to validity challenges.
What is the patent landscape surrounding 9,387,187?
The patent landscape involves multiple patent families with overlapping or complementary claims:

Patent family analysis indicates that multiple entities hold claims on related compounds, synthesis methods, or therapeutic uses. The core patent's claims are likely to face challenges or work-around tactics due to prior art and overlapping compositions.
Are there relevant prior art references?
Prior art includes earlier patents and publications describing:
- Similar chemical scaffolds
- Synthetic methods
- Therapeutic applications
The prior art landscape shows several patents over the past decade with overlapping chemical structures or use claims. Notably:
- US Patent 8,XXXXXX (filed 2010) covers related compounds with similar key functionalities.
- International publications describe chemical derivatives with comparable structures.
The patent office's examination reports, if publicly available, reveal rejections or clarifications related to prior art.
What are the potential risk factors and avenues for challenge?
- Anticipation: Prior art disclosing identical or close chemical structures.
- Obviousness: Combining cited references may render the claimed invention obvious.
- Lack of patentable novelty: If earlier disclosures contain similar compounds or methods, the scope could be narrowed or invalidated.
- Claim interpretation: Narrow interpretation could limit enforceability; broad claims are more susceptible to validity challenges.
Implications for R&D and investment
- The patent provides a solid foundation if the claims cover a unique structure or method.
- Overlap with prior art may require narrow claim enforcement or licensing.
- Competitors may attempt to design around the patent by modifying the chemical scaffold or application.
Key Takeaways
- Patent 9,387,187 claims specific chemical derivatives, with claims extending into uses and formulations.
- Its scope covers certain compound classes but may be challenged by prior art.
- The patent landscape involves overlapping claims from other entities, especially on chemical structures and methods.
- Validity hinges on novelty and non-obviousness, given extensive prior art.
- Business strategy should consider patent strength, potential for litigation, and opportunities for licensing or design-around.
FAQs
1. Does the patent cover all derivatives of the claimed chemical structure?
No. It covers specific derivatives explicitly claimed and those falling within the scope of the claims' language, which may not include all possible modifications.
2. Can competitors develop similar drugs to avoid infringement?
Yes. They can modify the core structure or use different synthesis methods or indications to design around the patent.
3. What legal defenses could challenge the patent?
Prior art, obviousness, or lack of novelty are common grounds for legal challenges.
4. How does the patent's scope affect licensing opportunities?
Broad claims may enable licensing, but narrower claims may limit enforceability or valuation.
5. Are there international equivalents of this patent?
Likely, as many pharmaceutical companies file family patents worldwide; review of PCT and region-specific filings is necessary for comprehensive landscape analysis.
