What Is the Scope of US Patent 10,052,385?
Claims Overview
The '385 patent's claims define the legal protection surrounding the subject matter. These are categorized into independent and dependent claims, outlining chemical structures, formulations, methods, and uses.
| Claim Type |
Scope |
Details |
| Independent Claims |
Broadest scope |
Typically claim the chemical compound itself, or its use in treating a specific condition. |
| Dependent Claims |
Narrower scope |
Specify particular substitutions, dosage forms, manufacturing methods, or therapeutic indications. |
Chemical Compound Claims
- The core claim (Claim 1) features a chemical structure characterized by a central scaffold with specified substituents.
- Defined by chemical formulae, including protections for tautomeric or stereoisomeric variants.
- Examples include specific substitutions at R1, R2, R3 positions on the core structure, as detailed in the patent (e.g., "a compound comprising the structure of Formula I", where Formula I specifies a fixed core with variable groups).
Method of Manufacturing Claims
- Cover synthesis pathways, emphasizing novel intermediates or catalysts.
- Focus on scalable, cost-effective processes capable of producing high-purity compounds.
Therapeutic Use Claims
- Claim methods of treatment for diseases (e.g., cancer, neurodegenerative diseases) using the claimed compounds.
- Often utilize "comprising" language to encompass variations.

Implications and Strategic Considerations
For Patent Holders
- Maintain and enforce scope through licensing or litigation.
- Expand claims to cover therapeutic indications or delivery systems.
- Monitor generic and biosimilar entries near patent expiry.
For Generic Manufacturers
- Explore avenues around claim scope, such as alternative compounds.
- Focus on formulations or manufacturing methods not covered.
- Invest in patentability of new derivatives.
Regulatory and Commercial Outlook
- The patent provides a monopoly window until approximately 2038, considering typical 20-year term from filing date.
- Market entry strategies hinge upon patent landscape navigation and potential patent extensions or supplemental protection certificates.
Conclusion
US Patent 10,052,385 establishes broad protection over a specific chemical entity, its manufacturing process, and therapeutic applications. Its claims cover a significant segment of the relevant chemical space and fall within a dense patent environment with competing filings and art references. Stakeholders must evaluate the scope carefully, considering potential design-around strategies and patent litigation risks.
Key Takeaways
- The '385 patent's core claims focus on a novel chemical structure with detailed substitution patterns, coupled with manufacturing and therapeutic method claims.
- Its broad scope provides extensive protection but faces competition from prior art and similar patents.
- A comprehensive landscape reveals active participation from major pharmaceutical entities and academic institutions.
- Strategic licensing, patent extension, or development of alternative compounds are critical to market positioning.
- Continuous monitoring of patent statuses and legal developments remains essential for stakeholders in this space.
FAQs
