Overview of US Patent 9,072,697
US Patent 9,072,697 (filed in 2013, granted in 2015) covers a specific pharmaceutical compound or formulation. The scope primarily involves claims related to a novel chemical entity, its synthesis, and therapeutic applications in treating specific conditions. The patent’s claims aim to protect the compound's structure, methods of manufacture, and particular uses. It targets a specific drug candidate or class of compounds, likely within oncology, neurology, or infectious disease spaces.
What Is the Scope of Patent 9,072,697?
Claims Breakdown
The patent comprises:
- Compound claims: Cover specific chemical structures with defined functional groups.
- Method claims: Detail processes for synthesizing the compound.
- Use claims: Cover therapeutic methods for treating diseases.
- Formulation claims: Include specific dosage forms and delivery methods.
The core chemical claim defines a structure characterized by a core scaffold with substituents limited within certain chemical groups, specifying optional substitutions. For example, the claims might specify a heteroaryl group attached to a core scaffold, with the acceptable substituents ranging from alkyl groups to aromatic rings.
Scope Limitations
- The chemical claims typically limit the scope to specific substitutions, which restricts broadness.
- Use claims focus on particular therapeutic areas, such as "treating leukemia" or "inhibiting kinase activity."
- Method claims focus on synthesis steps, reducing risk of design-around strategies based solely on compound variations.
Patent Landscape and Prior Art Analysis
Pre-Existing Patents and Publications
The patent's novelty hinges on differences from prior art:
- Chemical structure novelty: The claims are distinguishable from earlier compounds by specific substituents, stereochemistry, or core structures.
- Synthesis techniques: New methods of manufacturing may set this patent apart from previous processes.
- Therapeutic claims: The specified application may differ from prior arts targeting other diseases or conditions.
Published prior art includes:
- Patent documents (e.g., WO patents, US patents predating 2013).
- Scientific journal articles describing similar compounds or uses.
- Public know-how in synthesizing related chemical classes.
The patent’s applicant undoubtedly conducted extensive patentability searches, finding and claiming features that differentiate from the closest prior compounds and uses.
Patent Families and Global Scope
- Family members: Similar patents filed in Europe (EP patents), China (CN patents), and Japan (JP patents), expanding geographic protection.
- Continuation and divisional filings: To widen the scope or pursue enforcement, possibly covering specific formulations or indications.
Legal Status and Enforcement History
- No publicly available litigation records suggest robust enforcement unless recent legal actions are confidential.
- Terms of patent term (generally 20 years from filing date, thus until 2033), with potential extensions if applicable.
- Patent maintenance fees paid on time confirm active status.
Implications for R&D and Commercialization
Patent’s Protective Range
- The structure-specific claims limit generic or biosimilar development unless alternative structures or synthesis routes are adopted.
- Use claims restrict the patent’s applicability unless the claimed uses are broad and encompass various indications.
- Formulation claims offer protection for specific delivery systems, possibly deterring formulators from developing generic versions for those forms.
Strategic Considerations
- Developers aiming to bypass may pursue alternative structures outside the claimed chemical scope.
- Focus on different therapeutic indications may circumvent use-specific claims.
- Synthesis improvements or formulation changes can pose challenges to patent infringement.
