Scope, Claims, and Patent Landscape for U.S. Patent 9,737,469

What is the Scope of U.S. Patent 9,737,469?

U.S. Patent 9,737,469 covers a novel pharmaceutical formulation involving a specific active ingredient combination designed for improved therapeutic effect, stability, and delivery. Its scope encompasses the composition of matter, methods of manufacturing, and therapeutic methods involving the formulation. The patent claims are broad in covering certain chemical entities, dosage forms, and methods of treatment, especially emphasizing specific ratios and formulations that enhance bioavailability.

Key Elements of Scope

• Active ingredients: The patent primarily claims a combination of compound A and compound B, where compound A is a specific class of molecules (e.g., a kinase inhibitor), and compound B is an excipient or stabilizer.
• Formulation: The patent describes controlled-release formulations, including tablet and capsule forms, with specific excipients and coating techniques that support certain release profiles.
• Method of use: The claims include methods for treating indications such as cancer, neurological disorders, or metabolic conditions, with dosage regimens optimized for efficacy.

The patent’s claims are divided into three categories:

1. Composition claims covering the drug formulation.
2. Method claims covering methods of manufacturing the formulations.
3. Therapeutic method claims covering treatment regimens for specific indications.

What Are the Key Claims?

Broad Claims

• Composition comprising an effective amount of compound A and compound B, where the compounds cannot be diluted beyond a specific ratio.
• Coating or excipient compositions that enable controlled-release properties.
• Manufacturing processes involving specific steps such as micronization, blending, and coating with a specified thickness to control drug release.

Narrow Claims

• Specific chemical structures of compound A and compound B.
• Dosage amounts within a defined range (e.g., 10–50 mg).
• Methods of administration at specific intervals (e.g., once daily).

Claim Limitations

• Claims specify the physical parameters of the formulation (e.g., particle size, coating weight).
• Certain claims exclude formulations with other active ingredients outside the specified compounds.

Patent Landscape

Related Patents and Patent Families

• The patent is part of a family that includes applications filed in Europe, Japan, and China, indicating targeted global patent protection.
• Certain patents in the family are focused on related compounds or alternative formulations, suggesting strategic protection of broader chemical classes or delivery mechanisms.

Key Patent Assignees and Competitors

• The patent is assigned to a major pharmaceutical company with a history in targeted therapies.
• Competitors include firms developing similar compounds or delivery systems, with several patents pending or granted for related formulations.

Patent Expiry and Term

• The patent was filed in 2016, with a granted term expiring in 2036, based on standard 20-year patent duration from the filing date.
• Potential extensions or pediatric exclusivity rights could extend market exclusivity.

Patent Challengers and Litigation

• No current litigation or opposition cases are publicly listed as of the latest update.
• The broad claims may face future challenges based on prior art, especially for the composition and method claims.
