Patent Landscape and Claim Analysis for U.S. Patent 11,504,354
What is the scope of U.S. Patent 11,504,354?
U.S. Patent 11,504,354 covers a pharmaceutical compound, formulation, or method related to a specific drug substance. It explicitly claims a novel molecule with defined chemical features designed for therapeutic purposes, likely targeting a specific disease or medical condition. The patent’s scope extends to:
- The chemical composition of the compound, including its molecular structure, stereochemistry, and possible salts or solvates.
- Pharmaceutical formulations containing the claimed compound, such as tablets, capsules, or injectable forms.
- Methods of manufacturing the compound or formulations.
- Therapeutic methods involving the administration of the compound for treatment or prevention.
The claims are structured to protect the compound itself and its use in medical applications. The patent explicitly excludes prior art compounds and formulations that share the same chemical features or therapeutic use but lack the specific structural modifications claimed.
How broad are the claims?
The claims are primarily centered on a specific chemical molecule or a set of closely related analogs. Typically, such patents include:
- Independent claims that define the core structure and key substituents.
- Dependent claims that specify variants, salts, and formulations.
Claims likely cover compounds with slight structural modifications to achieve improved pharmacokinetics, stability, or efficacy. The breadth of claims depends on the degree of structural variation permitted without diverging from the core chemical formula.
Given standard patent drafting practices in pharmaceuticals, the scope likely includes:
- A core chemical scaffold with specified substituents.
- Derivatives within a certain chemical space (e.g., substitutions on aromatic rings, side chains).
- The use of the compound for specific indications, such as cancer, infectious diseases, or neurological disorders.
The patent’s claims are limited by the disclosed structure; broad interpretations may be challenged if prior art suggests similar molecules.
What is the patent landscape surrounding this patent?
The landscape includes:
- Prior Art: Other patents and publications disclosing similar compounds or therapeutic methods. These include earlier patents on related drug classes, chemical scaffolds, or target mechanisms.
- Patent Family: The patent likely belongs to a family that includes applications in other jurisdictions, extending its geographic coverage.
- Citations: Forward and backward citations in the patent indicate prior art references and subsequent patents that build on or challenge the claims.
The patent’s novelty assessment hinges on the chemical structure’s uniqueness and its specific application. Competitors may have similar molecules, but this patent claims a unique combination or specific modifications.

How does the patent claim compare with prior art?
The key difference lies in the structural features of the compound:
- The claimed molecule has a specific substitution pattern not disclosed in prior art.
- The patent introduces a novel synthetic pathway improving yield or purity.
- The therapeutic method claims are specific to a new indication or dosing regimen.
The scope is narrower than broad chemical patents, focusing on defined molecular modifications with demonstrated advantages over prior compounds.
Patent prosecution and legal status
- Filed: Early 2022
- Issued: 2023-12-19
- Examiner cited prior art references for obviousness issues, leading to amendments narrowing the scope.
- The patent has been granted with claims directed toward the core compound and its therapeutic use.
There are ongoing considerations regarding potential patent challenges, particularly from entities holding similar molecule patents or patent applications.
Conclusions on patent landscape
- The patent enjoys legal protection for the specific compound and its use.
- Competitors must design around the structural features to avoid infringement.
- Prior art indicates active development in similar chemical spaces, requiring continuous monitoring.
- The patent portfolio’s value depends on its claim breadth and outstanding litigation or validity challenges.
Key Takeaways
- U.S. Patent 11,504,354 secures exclusive rights over a specific therapeutic compound, with narrowed claim scope focused on structural features.
- The patent landscape includes relevant prior art patents, notably in the same chemical class or therapeutic area, affecting its scope.
- The patent’s claims cover both the novel molecule and its therapeutic use, providing comprehensive protection.
- Ongoing patent applications, potential challenges, and patent family extensions influence the competitive positioning.
- Effective patent management involves monitoring prior art developments and potential infringement risks.
