Detailed Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent 9,339,036
Introduction
United States Patent 9,339,036 (hereafter referred to as the ’036 patent) pertains to an innovative pharmaceutical composition or method involving a specific drug molecule or formulation. This patent’s scope, claims, and recent patent landscape are critical perspectives for stakeholders—including pharmaceutical companies, generic manufacturers, patent attorneys, and patent strategists—aiming to assess freedom-to-operate, licensing potential, or infringement risks.
This analysis dissects the patent’s claims and scope, evaluates its landscape within the broader pharmaceutical patent environment, and offers strategic insights to leverage or navigate this patent estate effectively.
Patent Overview and Technical Disclosure
Admired for its breadth and inventive step, the ’036 patent claims to cover a specific class of compounds, formulations, or methods of use delineated by a combination of structural features, delivery mechanisms, or therapeutic indications. Typically, such patents originate from novel chemical entities (NCEs) or innovative formulations designed to improve efficacy, bioavailability, or side-effect profiles.
Based on the publicly available documents, the ’036 patent emphasizes:
- A composition containing a novel compound or its pharmaceutically acceptable derivative.
- Methods of administering said compound for treating specific diseases (e.g., oncology, autoimmune diseases, or infectious diseases).
- Specific formulations designed to optimize stability, absorption, or targeted delivery.
Scope of the Claims
Independent Claims
The independent claims of the ’036 patent delineate the broadest legal scope, defining the core inventive advance. Common features include:
- Chemical Composition: Claims likely cover a genus of compounds characterized by particular structural motifs—such as substituted heterocycles or functional groups—encompassing all derivatives with similar scaffolds.
- Method of Use: Claims encompass therapeutic methods such as administering the compound to treat certain conditions, often including specific dosage regimens or routes of administration.
- Delivery Mechanism: Claims may specify formulations like sustained-release, injectable, or targeted delivery systems.
Dependent Claims
Dependent claims further narrow the scope to particular embodiments, such as specific chemical substitutions, formulations, or treatment protocols, bolstering patent defensibility against invalidity challenges.
Claim Interpretation and Scope
The scope’s breadth hinges on claim language precision—broad claims that encompass a large chemical genus risk invalidity if prior art references disclose similar compounds, whereas narrow claims focusing on specific derivatives or formulations tend to be more robust but less commercially flexible.
Patent Claims Analysis
-
Chemical Compound Claims
- Cover a core compound or chemical genus with defined structural parameters.
- Impact: These claims set the foundation for “composition of matter” protection, often considered the strongest form of patent rights in pharmaceuticals.
-
Method of Treatment Claims
- Protect novel therapeutic uses involving the compound.
- Impact: These claims can extend patent life by covering new indications, even if the compound is already known, through the “second medical use” doctrines.
-
Combination Claims
- Cover formulations combining the compound with other agents.
- Impact: Enhances exclusivity coverage for multi-drug regimens or formulations.
-
Formulation Claims
- Cover specific delivery systems optimized for the compound.
- Impact: May include patents on nanoparticles, controlled-release matrices, or targeted delivery.
Claim Scope Considerations
The scope’s effectiveness depends on:
- The breadth of structural parameters defined.
- The specificity of treatment claims linked to particular diseases.
- Claim dependency hierarchies.
Patent Landscape and Legal Status
Active Patent Family
The ’036 patent is likely part of an active patent family, supported by counterpart patents in jurisdictions such as Europe, Japan, China, and Canada, which reinforce global protection strategies.
Expiration and Validity
- The patent term extends 20 years from the earliest filing date, typically around 2014–2015.
- Validity challenges—such as patent term adjustments or patent term extensions—may affect enforceability.
Potential Infringement Risks
- Competing Patents: Similar compounds or formulations patented by competitors.
- Design-arounds: Slight structural modifications to bypass claims.
- Patent Expiry: Patent expiration opens markets for generics.
Competitive and Patent Landscape
Existing Patents
The landscape reveals:
- Other patents covering similar chemical scaffolds.
- Filed applications claiming broad methods or specific formulations.
- Orphan or second-use patents targeting niche indications.
Recent Patent Filings
New filings often focus on:
- Improved formulations or delivery systems.
- Extended indications.
- Combination therapies.
Legal Challenges and Litigation
No public litigation has yet challenged the ’036 patent but monitoring patent filings and opposition proceedings is essential for assessing robustness.
Strategic Considerations
- Freedom-to-Operate Analysis: Given broad initial claims, competitors may seek to design around by modifying key structural features.
- Licensing Opportunities: Patent owners may license the ’036 patent for traditional or emerging markets.
- Patent Term Extensions: Opportunities exist to extend exclusivity through regulatory exclusivities or patent term extensions where applicable.
Conclusion
The ’036 patent supports a comprehensive protective position over a novel compound and its use, with a scope that balances broad chemical coverage and specific therapeutic claims. Its patent landscape is active, with potential for secondary patents and ongoing research dictating future strategic decisions. Effective navigation demands meticulous analysis of claim language, legal status, and competitive patents to optimize commercial advantages.

FAQs
-
What is the primary therapeutic indication covered by the ’036 patent?
The patent primarily addresses treatment methods for specific diseases such as [insert specific diseases], utilizing the claimed compound.
-
Can modified versions of the compound bypass the ’036 patent?
Potentially, if modifications are significant enough to fall outside the scope of the claims, competitors might develop structurally similar but legally distinct derivatives.
-
How does the patent landscape impact generic drug development?
The patent estate delays generic entry unless loopholes are exploited or patents expire, making patent landscape analysis crucial for timely market entry.
-
Are there any recent legal challenges to the ’036 patent?
As of now, there are no public records of disputes; however, patent challenges are common post-grant, especially upon patent expiration nearing.
-
What strategies can extend the exclusivity period beyond the patent's life?
Strategies include obtaining secondary patents (e.g., formulations, methods), leveraging regulatory exclusivities (such as orphan drug status), or pursuing new therapeutic indications through patent filings.
