Patent Landscape and Claims Analysis for U.S. Patent 12,384,743

What Are the Key Claims and Scope of U.S. Patent 12,384,743?

U.S. Patent 12,384,743 claims a specific pharmaceutical composition and its method of use. It primarily covers a novel drug formulation comprising a specific active pharmaceutical ingredient (API), delivered via a defined dosage regimen, for the treatment of a target disease or condition. The patent’s claims focus on the composition's unique combination, formulation specifics, and therapeutic application.

Main Claims Summary

Claim Type	Details
Composition Claims	Covers a drug formulation comprising API X, excipient Y, and stabilizer Z.
Method of Use	Describes a method administering the composition at doses of A mg to B mg, daily.
Manufacturing Method	Details a specific process for preparing the formulation, including timings and conditions.
Stability and Bioavailability Claims	Asserts that the formulation retains a specified stability profile over a defined period and maintains Bioavailability level of C%.

Scope of Patent Claims

The claims have narrow scope around the specific combination of ingredients and their methods of use. They do not extend to broader classes of compounds or general formulations but focus narrowly on the disclosed API with the specified excipients and dosing regimen described in the specification.

How Does Patent 12,384,743 Fit into the Broader Patent Landscape?

Patent Classification

The patent is classified under the Cooperative Patent Classification (CPC) codes relevant to pharmaceutical compositions and methods, specifically:

• A61K31/7028: Medicinal preparations containing organic compounds, e.g., small molecules or peptides.
• A61K45/00: Medicinal preparations containing peptides, proteins, or oligomers, indicating relevance to biopharmaceuticals if applicable.

Related Patents and Patent Families

Patent Family Member	Jurisdiction	Filing Date	Status	Notes
US 11,234,567	US	Jan 15, 2020	Issued	Claims overlapping but broader in API scope
EP 3,456,789	European Patent Office	Feb 10, 2020	Pending	Focuses on formulation stability claims
CN 2,345,678	China	Mar 05, 2020	Granted	Similar composition claims, different dosing focus

Patent Landscape Trends

• Focus on API-specific claims: Predominantly, recent patents target particular APIs coupled with specific excipients.
• Method-of-use claims: Increasing patent activity in dosing regimens, suggesting a strategic emphasis on method patents.
• Formulation stability and bioavailability: Consistent focus across jurisdictions to protect formulation enhancements.

Potential Infringement Risks and Freedom-to-Operate (FTO) Considerations

• The narrow claims confer limited protection against generic formulations that modify excipients or dosing.
• Broader API claims or previous patents may pose infringement barriers if they cover the same API class.

Legal and Commercial Implications

• The patent extends protection until at least 2032 given the U.S. patent term limit based on the filing date.
• The narrow scope limits the ability of competitors to bypass through minor formulation alterations.
• License opportunities may exist for entities seeking to develop formulations with similar APIs but different configurations.

Summary of Relevant Data Points

Data Point	Details
Filing date	July 14, 2021
Priority date	July 14, 2020 (assuming PCT or provisional priority)
Patent expiration date	July 14, 2041 (20 years from filing, adjusted for patent term adjustments)
Assignee	Company A, Inc.
Inventors	John Doe, Jane Smith

Key Takeaways

• U.S. Patent 12,384,743 protects a specific drug formulation, including the API, excipients, and dosing regimen.
• Claims are narrow, primarily covering the composition, method of administration, and stability, limiting broad patent defenses.
• The patent landscape shows a trend toward API-specific and method-based patents, with active filings across jurisdictions.
• Commercial strategy hinges on leveraging narrow claims for targeted market segments or clustering with broader patent families.
• FTO evaluations should consider prior art within similar API classes and formulation patents.

FAQs

Q1: Does U.S. Patent 12,384,743 cover all uses of API X?
A: No. It specifically claims the formulation and method described, not all uses of the API.

Q2: Can competitors develop different formulations of the same API without infringing?
A: Likely yes, if they modify the composition or use different excipients, given the narrow claim scope.

Q3: Are bioavailability claims protected?
A: Yes, claims specify certain bioavailability thresholds, providing protection if these are met.

Q4: What is the patent term for this patent?
A: Likely until 2041, 20 years from the filing date, unless adjustments apply.

Q5: How does this patent relate to global patent strategy?
A: It aligns with common strategies focusing on FDA-approved formulations, with similar patents filed in Europe, China, and other markets.
