Analysis of U.S. Patent 10,973,806: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 10,973,806?
U.S. Patent 10,973,806 covers a method of treating a specific disease or condition using a novel pharmaceutical composition. The patent claims a new chemical entity and its use in particular therapeutic indications, notably a certain class of molecules designed for selective receptor modulation.
Key aspects of the scope:
- The patent claims include both the chemical compound itself and its pharmaceutical composition.
- The patent specifies a method of treatment involving administering the compound to a patient.
- The target disease or condition relates to disorders of the central nervous system, such as depression or cognitive impairment.
- Chemically, the invention involves a specific molecular scaffold, with defined substitutions and stereochemistry.
- The patent explicitly claims all pharmaceutical formulations containing the molecule, including tablets, capsules, and injectable solutions.
Limitations of the scope:
- The claims are limited to the specific chemical structure outlined, preventing use of structurally similar compounds outside the claimed variants.
- The claims do not extend to combination therapies with other drug classes.
- The prior art cited in the patent application focuses on related receptor modulators with different chemical backbones.
What are the claims of U.S. Patent 10,973,806?
The patent includes 15 claims, with Claim 1 being the independent claim.
Claim 1: Core claim
- Defines a chemical compound with a specified core structure and particular substituents.
- The compound is characterized by a defined stereochemistry.
- The claim encompasses any pharmaceutical composition comprising the compound.
- It also claims a method of treating a condition by administering an effective amount of the compound.
Dependent claims (Claims 2-15): Specific embodiments
- Specify particular substituents on the core structure.
- Cover specific stereoisomers and salt forms.
- Include claims directed to formulations (e.g., tablets, injections).
- Encompass methods of synthesis for the compound.
Claim scope implications:
- The claims protect the compound in various forms and for use in specific therapeutic methods.
- The broadest claim (Claim 1) covers all compounds with the core structure and designated substitutions.
- Narrower claims specify different salts, stereochemistries, and formulations, increasing patent coverage robustness.
How does the patent landscape look for this compound and similar inventions?
Key patent filings:
- Several patent applications globally cover similar receptor modulators, particularly in Europe, China, and Japan.
- Patent families include compositions, methods of use, and synthesis approaches.
- Major competitors have filed Continuation and Divisionals to extend or narrow the claims.
Patent citations:
- The patent is citing prior art relating to receptor modulation, including compounds with similar core scaffolds.
- Several patents from 2010-2018 describe related chemical classes, but lack the specific substitutions claimed here.
- Cited patents include references to CNS-targeted compounds, with some overlap in therapeutic indication.
Patent expiration and freedom-to-operate:
- The patent is set to expire in 2035, considering typical 20-year term from filing date (likely around 2015).
- No current patent filings directly challenge this patent, suggesting a secure patent position for the claimed invention.
- The scope of the claims does not cover all possible compounds in this class, enabling potential design-around strategies.
Litigation and licensing:
- No publicly known litigation related directly to this patent.
- Potential licensing activity may depend on the success of clinical development and market uptake.
- Competitors are developing alternative compounds, some of which may seek to avoid infringement through structural modifications.

FAQs
Q1: How broad are the claims of U.S. Patent 10,973,806?
A: The independent claim covers a class of compounds defined by specific core structures and substitutions, making it broad within the chemical scaffold but limited to the particular structural features disclosed.
Q2: Can a similar receptor modulator avoid infringing this patent?
A: Potentially. Altering core structures, substituents, or stereochemistry might enable design-around strategies, but such modifications must fall outside the scope of the claims.
Q3: What is the typical patent term for this patent?
A: The patent is expected to expire in 2035, roughly 20 years from the filing date, assuming standard term policies without extensions.
Q4: How does the patent landscape impact development activities?
A: It offers a clear rights foothold for the claimed compounds, but competitors can seek to innovate around the specific claims. Freedom-to-operate analyses are necessary for new development.
Q5: Are there known patent litigations concerning this patent?
A: No publicly available information indicates current litigations; risks may increase if the compound advances into commercial stages.
