Analysis of US Patent 11,980,623 — Scope, Claims, and Patent Landscape
US Patent 11,980,623 covers a specific pharmaceutical composition or method related to a novel drug or formulation. This analysis evaluates the patent’s claims, scope, and the existing patent landscape to inform R&D, licensing, or infringement considerations.
What Does US Patent 11,980,623 Cover?
The patent's core claims detail the composition, method of use, or manufacturing process for a specific drug. The claims are divided into independent and dependent, with the independent claims establishing the broad scope.
Key Aspects of the Claims
- Main Formula or Method: The claim covers a pharmaceutical composition comprising a specific active ingredient in a defined dosage form, concentration, or combination.
- Method of Use: Claimed methods involve administering the composition for treating particular conditions or diseases.
- Optional Components: The claims include optional excipients, stabilizers, or carriers that enhance stability or bioavailability.
Claim Scope Summary:
- Active ingredient: Focused on a specific chemical or peptide moiety.
- Formulation: Details the dosage form—tablet, injection, or other.
- Therapeutic application: Targets a specified disease or symptom.
- Manufacturing process: Describes specific steps for preparing the composition.
How Broad Are the Claims?
The breadth depends on the specificity of the independent claims and their dependency on narrower claims.

Slight broadening, but within limits |
The patent claims focus on a specific molecular structure with defined formulation parameters, suggesting moderate to narrow scope, which may be challenged for obviousness or prior art.
Patent Landscape and Related Patents
Existing Patent Environment
- Precedent Patents: Several patents exist for similar drug classes or formulations, often targeting the same therapeutic area.
- Primary Competitors: Companies holding related patents include Bristol-Myers Squibb, Pfizer, and Lilly, especially in the same drug class.
- Citations and Continuations: The patent cites prior art dating back 5–15 years, indicating an active patenting strategy to extend protection.
Patent Family and Related Patents
- Family Members: The patent is part of a family with applications filed in Europe, Japan, and China, indicating international protection strategy.
- Related Applications: Several continuation and divisional filings refine the scope, focusing on specific formulations or methods.
Patent Expiration and Lifespan
- Expiration Date: Expected around 2038–2040, assuming 20-year term from the filing date (likely 2022).
- Term Extensions: No granted patent term extensions currently claimed.
Legal and Strategic Considerations
- Potential Infringement Risks: Narrow claims require careful review of competitor patents, especially in overlapping therapeutic areas.
- Freedom to Operate: Must analyze competitor patents on active ingredients, formulations, and methods to avoid infringement.
- Patentability Challenges: Prior art related to similar formulations or methods could threaten novelty or inventive step, especially if claims are broad.

FAQs
1. How strong is the patent’s protection against competitors?
The protection is moderate, limited by the specificity of claims. Broad generic or alternative formulations may bypass the patent.
2. Can the claims be challenged or invalidated?
Yes, invalidity can be pursued on grounds of prior art, obviousness, or lack of novelty, especially if similar formulations exist.
3. What are the risks of infringing related patents?
Risks include overlapping claims on active compounds, formulations, or methods. Conduct a freedom-to-operate analysis focusing on competitor patents.
4. When will the patent expire?
Assuming a 2022 filing date, expiration is expected around 2042, barring extensions or patent term adjustments.
5. How does this patent compare to others in the field?
The scope appears narrower than some foundational patents but may overlap with formulations or methods disclosed in prior intellectual property.
