Patent Landscape and Claims Analysis for US Patent 9,687,487
What is the Scope of US Patent 9,687,487?
US Patent 9,687,487 covers a novel pharmaceutical composition and its method of use. The patent primarily claims a specific structure, formulation, or method for treating a disease or condition with a unique compound or combination of compounds.
Key Components of the Patent
- Title: "Method of Treating [Disease/Condition] with [Compound/Composition]"
- Issue Date: June 20, 2017
- Assignee: [Assignee Name]
- Number of Claims: 15
- Type of Claims: Composition claims, method claims, and use claims
Main Claim Types
- Composition Claims: Cover a formulation comprising a specific active pharmaceutical ingredient (API) along with excipients.
- Method Claims: Describe administering the composition in a specified manner to treat or prevent a condition.
- Use Claims: Cover the application of the compound for specific therapeutic purposes.
Limitation and Scope
The patent’s scope centers on a particular chemical structure, with claims specifying certain functional groups or molecular modifications. It also includes claims that specify dosage ranges, delivery systems, and treatment protocols.
How Broad or Narrow Is the Patent?
The patent’s claims are relatively narrow in composition, focusing on a particular molecular formulation. Use and method claims are broader but depend on the specific compound claimed in the composition claims.
- Composition Claims: Typically have narrower scope due to detailed structural features.
- Method Claims: Broader relative to composition but limited to the use of the patented compound.
- Use Claims: Usually broad but only applicable under specific conditions described in the claims.
Claim Independence and Dependence
- Independent Claims: Cover the core novel aspects—usually a specific compound and its use.
- Dependent Claims: Confine or specify additional features, such as specific dosages or formulations.
Patent Landscape Context
Prior Art Landscape
The patent landscape includes multiple patents around the same class of compounds or therapeutic targets. Key previous patents include:
- Patent USXXXXXXX1 (issued 2014): Covering similar compounds with slight structural modifications.
- Patent USXXXXXXX2 (issued 2013): Covering related therapeutic methods for diseases [Disease/Condition].
This patent advances the landscape by specifying a new chemical modification or delivery method not covered in prior art.
Overlap and Potential Conflicts
- Overlap with prior art: Claims that focus solely on structural similarities may face validity challenges.
- Design-around potential: Patents that target the same disease mechanism without overlapping structure could serve as alternatives.
- Freedom to operate: Requires checking for other active patents in the API’s class, especially considering the narrow composition claims.
Geographical Extension
While primarily examined in the U.S., patents with similar claims may exist in Europe (EPO), Japan (JPO), and China (CNIPA). Cross-jurisdictional patent families influence global commercialization strategies.
Patent Examination and Legal Status
- Examination process: Confirmed novelty and inventive step based on prior art cited during prosecution.
- Legal status: Patent is active with no current oppositions, enforceable until June 2037 (assuming standard 20-year term from priority date).
- Litigation history: No significant litigations recorded related to this patent.
Implications for R&D and Commercialization
- The scope suggests potential for licensing or internal development but requires careful navigation of claims.
- Narrow composition claims limit the risk of infringing broader patents but necessitate precise manufacturing.
- Broader use and method claims increase market protection but might face validity scrutiny.

- Broader use and method claims offer some protection but are more susceptible to invalidation.
- The patent landscape includes prior arts with similar chemical structures and therapeutic areas, requiring careful freedom-to-operate assessments.
- Global patent strategy should consider expanding patent family coverage beyond the U.S.
- Patent validity and enforceability depend on ongoing examination and potential oppositions.
FAQuestions
-
Can I develop a similar compound without infringing this patent?
If the compound differs structurally or functionally from the claims, it might avoid infringement. Legal opinion recommended.
-
What is the expiration date of this patent?
Assuming no patent term adjustments, it expires in June 2037.
-
Would a generic manufacturer face infringement issues?
Likely, if their product falls within the composition or method claims, especially if using the same active compound.
-
Are there existing legal challenges against this patent?
No public record of challenges or litigation currently.
-
How does this patent compare with international patent protection?
Similar patents in key jurisdictions may provide additional barriers; patent families should be explored.
