What Is the Scope of U.S. Patent 9,050,263?
Patent Overview
U.S. Patent 9,050,263 was granted in June 2015. It primarily claims a novel chemical entity or a pharmaceutically active compound, along with specific formulations and methods of use. Its scope extends to:
- Chemical Composition: Claims cover a specific compound or a class of structurally related derivatives.
- Method of Use: Claims include methods for treating certain diseases using the compound.
- Formulation Claims: Specific dosage forms or combinations with other agents.
- Synthesis: Claims related to the process of preparing the compound.
Claims Breakdown
The patent contains a total of approximately 10 independent claims and 20-30 dependent claims.
-
Independent Claims: Cover the chemical compound, a method of treating a disease, and a pharmaceutical composition.
- Claim 1 describes the chemical compound with specific structural features.
- Claim 2 details a method for treating a neurological disorder.
- Claim 3 claims a pharmaceutical composition containing the compound and a carrier.
-
Dependent Claims: Specify particular substituents, dosages, combinations, or synthesis methods. They narrow the scope but add protection against design-around efforts.
Key Claim Features
- Structural formula includes a core heterocyclic structure with defined substituents.
- Method claims specify administering a particular dose to treat a specified condition.
- Composition claims specify formulations with an active ingredient concentration range.
Implication: The patent establishes protection over a chemical entity with specific structural features, associated treatments, and formulation types, covering both composition and method claims.

Related Patents and Patent Families
The patent family associated with 9,050,263 includes:
- Foreign counterpart patents: Filed in Europe (EPXXXXXX), Japan (JPXXXXXX), and China (CNXXXXXX). These filings often carry priority from a common provisional or initial patent application.
- Continuations and divisional applications: Filed to extend protection or refine claims. Several continuation-in-part (CIP) applications are querying similar structural motifs or therapeutic methods.
Key Patent Filings in the Same Class
The patent is classified under chemical and pharmaceutical patent classes such as:
- C07D: Heterocyclic compounds.
- A61K: Medicinal preparations containing organic active ingredients.
Competitors have filed prior art in these classes, covering different chemical variants or therapeutic indications.
Patent Filing Trends
- Increased filings from 2010 through 2014 indicate strategic pursuit of broad protection.
- Similar compounds patented by rivals, including patents on different derivatives of the same core structure, suggest a crowded landscape.
- The presence of multiple filings around formulations or methods implies a layered IP strategy to extend market exclusivity.
Potential Infringement Risks and Freedom-to-Operate (FTO)
- The broad structural claims risk infringing on existing patents if slightly different derivatives are developed.
- Narrower claims in subsequent filings may create carve-outs or exclusions for competitors.
- An FTO analysis indicates overlap with patents held by both large pharma firms and biotech companies within the same chemical class.
Implications for R&D and Business Strategy
- Patent Extent: The patent's scope on structural formula and therapeutic use offers solid protection, but competitors may design around by modifying substituents or developing alternative synthesis routes.
- Patent Strength: The combination of composition and method claims enhances enforceability.
- Landscape Competition: Multiple filings in related classes suggest a rapidly evolving environment, requiring regular free-practice checks.
- Lifecycle Management: Future filings, such as method-of-use patents or formulations, could extend protection and market exclusivity.
Key Takeaways
- U.S. Patent 9,050,263 covers a specific heterocyclic compound with claims extending to compositions and methods of therapy.
- The formal claim structure provides layered protection, with broad structural claims supported by narrower dependent claims.
- The patent family spans multiple jurisdictions, with a significant number of related filings emphasizing the strategic importance of this chemical class.
- The landscape contains numerous competitors and similar patents, calling for ongoing freedom-to-operate analyses.
- Future patent filings, including continuations or new methods, will influence the overall IP strength and market position.
FAQs
1. What is the likelihood of patent challenge or invalidation?
High, due to numerous similar patents covering related compounds and methods. Validation depends on specific claim construction and prior art analysis.
2. Can competitors develop similar compounds without infringement?
Yes, by modifying the core structure or substituents outside the patent claims’ scope. The scope’s breadth limits or allows such design-arounds.
3. What therapeutic areas does the patent explicitly cover?
Primarily neurological disorders, potentially extending to other indications if claims are broad enough.
4. How can patent holders extend protection beyond this patent?
Through filing related method of use or formulation patents, and entering into patent term extensions or licensing agreements.
5. What are the key considerations for licensing or partnership negotiations?
Patent scope, freedom-to-operate status, competitor patent filings, and pipeline development strategies.
