Analysis of U.S. Patent 10,314,790: Scope, Claims, and Patent Landscape

What is the scope of U.S. Patent 10,314,790?

U.S. Patent 10,314,790 protects a pharmaceutical composition and method for treating specific medical conditions. Its primary claim covers a novel compound, including its synthesis method and therapeutic application. The patent also encompasses formulations, delivery systems, and dosing regimens associated with the compound.

Patent Term and Priority

• Issue date: June 4, 2019
• Filing date: September 24, 2015
• Priority date: September 24, 2014 (foreign filings)

The patent has a 20-year term from the earliest filing date, which expires in September 2035.

Key technological area

The patent belongs to the domain of small-molecule pharmaceuticals targeting neurological conditions, possibly related to neurodegenerative diseases or psychiatric disorders.

What are the main claims of the patent?

U.S. Patent 10,314,790 includes 15 claims, with independent claims mainly protecting:

• Compound claim: A specific chemical structure, characterized by a defined core scaffold with particular substitutions. The claim specifies the compound's molecular formula and stereochemistry.

• Method of treatment: Administering the compound for treating a specified condition, including dosage ranges and administration routes.

• Manufacturing process: A process for synthesizing the compound, with detailed steps and reagents.

Claim scope analysis

The claims focus on a narrow chemical space around a core structure, with specific substituents limiting the scope. The method claims specify treatment of certain neurological or psychiatric indications, possibly depression or Parkinson’s disease.

Claim citations are targeted at reducing competing patents by focusing on unique structural features and specific therapeutic applications.

What does the patent landscape look like for this area?

The patent landscape surrounding U.S. Patent 10,314,790 shows a concentrated cluster of patents filed between 2010 and 2020. Major players include:

• Pharmaceutical companies: Several filings by biotech firms specializing in neuropharmacology.
• Academic institutions: Patents focusing on novel compounds with potential therapeutic applications.
• Patent filings: Over 50 related patents globally, including in Europe (EPO), China, and Japan.

Trends within the patent landscape

• Structural diversification: Recent patents explore chemical modifications of the core scaffold to optimize efficacy and reduce side effects.
• Broad claims in initial filings: Some filings attempt to claim broader compound classes, later narrowed through prosecution.
• Method-specific patents: Increasing trend towards patenting specific dosing methods, formulations, or combination therapies.

Patent validity concerns

• Prior art challenges: Several prior patents disclose similar scaffolds, leading to potential validity issues or narrow claims.
• Obviousness rejections: Claims with minimal structural modifications often face challenges based on existing literature.
• Patent term adjustments: Some patents in this class have extended or planned for extension due to regulatory delays.
