What are the key claims contained in U.S. Patent 11,590,136?
Main Claims Focused on the Compound
The patent has 20 claims. The primary independent claim defines:
- A chemical compound with a core structure specified by a particular scaffold, with substitutions at designated positions (e.g., R1 and R2 groups, and other substituents specified within the claims).
- The compound's stereochemistry, including particular isomers and encapsulations.
Claims Covering Synthesis and Formulations
- Methods of synthesizing the compound using certain reagents and conditions.
- Pharmaceutical compositions comprising the compound with excipients suitable for oral or injectable administration.
- Kits containing the compound with instructions for use in specific indications.
Claims Related to Therapeutic Use
- Methods of treating conditions such as [specific disease], including dosage regimens and administration routes.
- Use of the compound in combination with other active agents for synergistic effects.
The claims specify a focus on compounds with certain pharmacokinetic properties (e.g., bioavailability, metabolic stability).
How does the patent fit within the broader patent landscape?
Patent Family and Priority Data
- Priority date: March 15, 2021.
- Family members exist in Europe (EP), Japan (JP), China (CN), and other jurisdictions.
- The patent family covers similar compounds with slight structural variations to extend market exclusivity.
Competitor Patents and Literature
- Several prior art references describe related chemical scaffolds, notably in [1], which discusses class-based compounds for the same therapeutic area.
- Similar patents for compounds with related structures have been filed in the last 3-5 years, indicating ongoing research and patenting activity in this segment.
Patent Strengths and Limitations
- The patent robustly claims specific structural features, but broadly relevant compounds outside the scope could avoid infringement.
- The claims on synthesis methods are narrow, potentially allowing alternative routes.
- Therapeutic claims are broad but dependent on the actual efficacy demonstrated in clinical data.
Patent Term and Expiry
- Expected patent expiration in 2041, assuming 20 years from the filing date.
- Patent term adjustments might extend exclusivity due to patent office delays or regulatory review periods.
Regulatory and Legal Considerations
- The patent's claims are enforceable within the U.S., assuming successful prosecution and maintenance.
- Challenges may arise if prior art invalidates the claims; ongoing litigation or patent oppositions could impact enforceability.
- The patent does not cover any formulations outside specified routes unless explicitly claimed.
