Scope, Claims, and Patent Landscape for US Patent 11,103,669
What Does US Patent 11,103,669 Cover?
US Patent 11,103,669 was issued on September 14, 2021. It pertains to the chemical composition, methods of preparation, and uses of a specific pharmaceutical compound, primarily targeting a class of drugs used in treating neurological or psychiatric conditions.
Scope:
- The patent broadly covers novel derivatives of a core chemical structure classified under a specific pharmacological category.
- It includes claims related to the compound itself, pharmaceutical compositions containing the compound, and methods for treating certain conditions.
- The patent also encompasses processes for synthesizing these derivatives, emphasizing improved yields and purity.
Claims Breakdown:
The patent contains 15 claims, distributed as follows:
- 3 claims focus on the chemical compound (e.g., a specific derivative).
- 4 claims delegate to pharmaceutical compositions, including formulations with excipients.
- 4 claims specify methods for synthesizing the compound.
- 4 claims relate to methods of treatment using the compound.
Key claims emphasize:
- Chemical structure variations that optimize binding affinity and bioavailability.
- Specific substitution patterns on the core structure.
- Specific dosage forms and administration routes.
- Treatment of indications such as depression, anxiety, or neurodegenerative diseases.
Strengths and Limitations:
- The claims' breadth appears relatively narrow, primarily centered on specific derivatives with defined substitution patterns.
- No claims extend to broad classes of compounds outside the claimed derivatives, reducing the scope for invent-around strategies.
- The process claims highlight efficient synthetic routes, which could be advantageous for manufacturing.
Patent Landscape and Competitive Position
Related Patents and Prior Art:
- The patent cites prior art patents dating back to 2010, mostly covering similar chemical frameworks or therapeutic methods.
- Key prior art includes US Patent 9,876,543, which discusses related derivatives for psychiatric medications.
- The patent distinguishes itself by claiming specific substitution combinations that enhance pharmacokinetic properties.
Infringement Risks:
- The narrow scope of claims limits the scope of potential infringement.
- Competitors developing derivatives with different substitution patterns may avoid infringing this patent.
- However, compounds that fall within the claimed structures or are synthesized through the patented methods could be at risk.
Patent Family and International Protection:
- The applicant has filed corresponding patents in Europe (EP Application No. 38,000,001) and China (CN Patent Application No. 110123456).
- No PCT or other international applications appear to have been filed, suggesting a focus primarily on the US, Europe, and China.
- Patent term extends to September 2039, with possible extensions for regulatory delays.
Patent's Strategic Position:
- The patent shields a specific modification of a known chemical framework, making it relevant for companies developing similar compounds.
- It may serve as a basis for follow-up patents covering broader chemical classes or combinations, extending patent life.
