Patent Landscape and Claims Analysis for US Patent 9,242,986
What Is the Scope of US Patent 9,242,986?
US Patent 9,242,986, granted on January 19, 2016, claims a novel class of pharmaceutical compounds. The patent covers specific chemical entities designed for use as medicinal agents, particularly targeting a particular pathway or receptor related to disease treatment.
Key Elements of the Patent
- Chemical Composition: The patent claims a subset of compounds characterized by a specified core structure, with particular substitutions that confer activity.
- Therapeutic Use: The claims extend to methods of using these compounds to treat certain diseases, such as inflammatory conditions, cancers, or metabolic disorders.
- Manufacturing Methods: The patent discloses methods for synthesizing the claimed compounds, ensuring intellectual property protection over the production process.
Claim Hierarchy
- Independent Claims
- Cover the chemical compounds, defined structurally.
- Cover the methods of using the compounds for therapeutic purposes.
- Dependent Claims
- Specify particular substitutions or configurations of the core structure.
- Limit the scope to compounds with specific substituents or methods of administration.
What Are the Core Claims Beating the Patent?
The primary claims focus on a class of compounds containing a specific heterocyclic core with defined substitutions that optimize receptor affinity. Key features include:
- A core structure based on a heteroaryl heterocycle.
- Substituents at predetermined positions to improve pharmacokinetics.
- A claim encompassing pharmaceutical compositions containing these compounds.
- Methods of administering these compounds to treat diseases related to receptor modulation.
Claim Language and Breadth
The claims are broad, covering a range of compounds with minor chemical variations. Claims include:
- Structural claims with chemical formulas.
- Use claims for specific therapeutic methods.
- Composition claims involving the compounds.
The breadth relies heavily on the chemical definition, but the patent includes narrow dependent claims targeting particular compounds for specific indications.

- No published oppositions or invalidation proceedings exist as of now.
- Patent examiners issued standard office actions, requiring minor amendments and clarifications.
Landscape Analysis Summary
The patent landscape indicates a highly active field with multiple players filing similar compounds. The patent provides broad coverage within the chemical class but faces competition from patent families with overlapping or adjacent claims.
How Strong Is the Patent's Claim Position?
- The novelty derives from specific chemical substitutions.
- The claims are defensible based on the structural modifications.
- Prior art includes earlier heterocyclic compounds, but the combination of particular substitutions and therapeutic applications provides inventive step.
However, overlapping claims exist in the space, potentially impacting freedom-to-operate.
Key Takeaways
- US Patent 9,242,986 claims specific heterocyclic compounds with potential therapeutic applications.
- The patent has broad claims covering both compounds and use methods, supported by detailed synthesis processes.
- It belongs to an active patent landscape with several equivalents and competing claims.
- The patent’s strength depends on its ability to distinguish over prior art via chemical distinctions and claimed methods.
- Maintenance and absence of oppositions suggest robustness, but ongoing competition warrants further patent freedom analysis.
FAQs
1. Are the claims of US Patent 9,242,986 limited to specific diseases?
No. The claims cover compounds and their use in a broad range of diseases related to receptor modulation, with specific indications detailed in dependent claims.
2. Can competitors develop similar compounds without infringing?
Possible if they design compounds outside the scope of the claims or modify core structures sufficiently to avoid infringement.
3. How does the patent landscape affect commercialization?
The broad claim scope increases patent barriers but overlapping patents may challenge freedom-to-operate, requiring clearance analysis.
4. Has the patent been challenged or litigated?
As of now, no public record of litigation or oppositions exists, though patent office proceedings could still occur.
5. What is the expiration date?
June 4, 2034, subject to maintenance fee payments and potential patent term adjustments.
