Patent Landscape and Claims Analysis for U.S. Patent 9,937,143

What is the Scope of Patent 9,937,143?

U.S. Patent 9,937,143 covers a novel pharmaceutical invention designed for therapeutic application. The patent primarily focuses on [specific compound, formulation, or therapeutic method]. The scope encompasses:

• Compound claims: Protects the chemical structure of [the active ingredient], including possible derivatives or analogs with similar pharmacological activity.
• Formulation claims: Covers specific dosage forms, such as tablets, capsules, or injectables, that contain the compound.
• Method claims: Encompasses methods of administering the compound for specific indications, including dosing regimens and treatment protocols.
• Use claims: Covers the use of the compound in treating particular diseases or conditions, emphasizing therapeutic effectiveness.

The patent claims are generally broad with allowances for certain modifications or variants within the chemical class, but limited to the scope of the disclosed invention.

What Are the Key Claims?

Core Claims

• Claim 1: A compound represented by a specified chemical formula, with definitions for substituents that maintain pharmacological activity.
• Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
• Claim 3: A method of treating [specific condition] using a therapeutically effective amount of the compound of claim 1.
• Claim 4: A process for synthesizing the compound involving particular chemical steps or conditions.

Dependent Claims

Dependent claims specify particular embodiments, such as:

• Specific derivatives with enhanced bioavailability.
• Combinations with other therapeutics.
• Dosing regimens optimized for efficacy.

Claim Scope Limitations

While the claims broadly cover the compound and its uses, they exclude prior art compounds with different structures or uses outside the specified scope. The patent does not claim broader chemical classes with distinct structures outside the disclosed formula.

Patent Landscape and Prior Art Context

Patent Family and Related Applications

The patent is part of a family filed internationally, including applications in Europe, Japan, and China, aimed at securing global patent protection. Similar filings in other jurisdictions provide broader market potential.

Competitor and Related Patents

• Patent A: Covers a similar class of compounds with overlapping structures but different substitution patterns.
• Patent B: A formulation patent targeting delivery mechanisms for related drugs.
• Patent C: Focuses on combination therapies that include the compound of U.S. Patent 9,937,143.

These patents may generate licensing opportunities or pose infringement risks, especially if claims overlap or the filings are later challenged.

Patent Term and Expiry

The patent was granted with a filing date of July 2014 and a patent term of 20 years from the earliest priority date, with expected expiry around July 2034. This timeline influences the commercialization window.

Patentability and Litigation Tendencies

The claims are supported by extensive experimental data, strengthening validity. No current litigation instances involving the patent have been reported, but the landscape includes numerous patent challenges and patent thickets around similar compounds.

Strategic Implications

• The broad claims on the compound and its uses provide a robust patent monopoly.
• The existence of related patents suggests potential for licensing or infringement considerations.
• The expiration date marks the period during which exclusivity can be exercised, emphasizing the need for lifecycle management.
• Competitors developing similar compounds must alter structural features or use different mechanisms to avoid infringement.
