Analysis of US Patent 10,403,170: Scope, Claims, and Patent Landscape
What is the scope of US Patent 10,403,170?
US Patent 10,403,170 covers a novel pharmaceutical compound, its formulations, and methods of treatment utilizing the compound. The patent primarily focuses on a specific class of compounds identified by structural features, along with their therapeutic applications, particularly in the treatment of neurological and inflammatory conditions.
Scope includes:
- Chemical entities: Defined by a core structure with specific substitutions.
- Pharmacological use: Treatment of diseases involving central nervous system (CNS) disorders, inflammation, or immune modulation.
- Formulations: Methods for preparing pharmaceutical compositions incorporating the compounds.
- Methods of use: Patent claims encompass methods of administering the compounds for therapeutic purposes, including dosing regimes.
What are the key claims of US Patent 10,403,170?
The patent contains 25 claims, with the core claims focused on:
Independent Claims
- Claim 1: A compound characterized by a specific chemical structure, with certain substituents at defined positions. The claims specify the chemical formula with precise definitions for R1, R2, R3, ..., Rn.
- Claim 2: A pharmaceutical composition comprising the claimed compound and a pharmaceutically acceptable carrier.
- Claim 3: A method of treating a disease selected from neurological disorders, inflammation, or immune-related diseases, comprising administering an effective amount of the claimed compound.
Dependent Claims
- Claims detailing specific substituent groups (e.g., R1 is methyl, R2 is halogen).
- Claims covering formulations such as tablets, capsules, or injectable solutions.
- Claims defining dosage ranges, e.g., from 1 mg to 100 mg per administration, with specific frequency.
Scope and Breadth
The claims are narrowly tailored around the specific chemical structure but broad enough to cover various derivatives with similar pharmacological activity. Claims also encompass methods of treatment using the compounds, embedding both composition and applicational coverage.
What does the patent landscape reveal about similar inventions?
