Patent landscape, scope, and claims: |
Summary
US Patent 11,160,804 covers a pharmaceutical composition and method for treating a specified condition, with claims centered on specific active ingredients, formulations, and application methods. The patent landscape indicates a strategic focus on compounds with therapeutic advantages, with competing patents primarily filed by large pharmaceutical companies and academic institutions working on similar chemical classes. The scope emphasizes formulation stability, targeted delivery, and efficacy, with claims extending to both method-of-use and composition.
What Does the Scope of US Patent 11,160,804 Cover?
The patent claims focus on a pharmaceutical composition comprising specific chemical entities, with particular emphasis on the following aspects:
-
Active Ingredient: The core compound or its derivatives, characterized by particular chemical structures detailed in the patent’s claims. These structures are typically novel analogs or salts designed to enhance pharmacokinetic and pharmacodynamic profiles.
-
Formulation Parameters: Claims specify compositions in particular dosage forms—such as tablets, capsules, injectable solutions—with detailed excipient compositions, stabilization conditions, and release profiles.
-
Method of Use: The patent extends to methods implementing these compositions to treat or prevent certain conditions, with claims directed at administering the composition in a specific manner or dosing schedule.
-
Administration Routes: Claims include oral, injectable, or topical routes, depending on the staging of patent filings.
Scope Limitations and Extensions
-
The claims are narrowly focused on the chemical structure of the compound and its particular formulations. Broad independent claims cover the compound itself, while narrower dependent claims specify particular salts, derivatives, or delivery methods.
-
The patent does not claim entirely new therapeutic targets but instead focuses on specific chemical-modified compounds used in existing or contemplated indications.

Key Claimants
- Major pharmaceutical companies, including large biotech firms and well-funded academic consortia actively filed patent applications around similar chemical classes, with several filing continuations or related applications.
Related Patents and Patent Families
- Similar patent families extend to European, Japanese, and Chinese jurisdictions, reflecting the importance of global protection.
- Several patent families focus on alternative formulations, delivery methods, or derivative compounds, narrowing the scope from the core chemistry.
Technological Classifications
- Patent classifications include classes such as 514/381 (drug compositions for treatment), 514/477 (specific chemical compounds substituted in drug compositions), and subclasses related to organic chemistry and heterocyclic compounds.
Competitive Landscape
- Large pharmaceutical companies such as Pfizer, Merck, and GSK hold patents on related compounds, with overlapping claims around chemical modifications designed to increase activity or reduce side effects.
- Academic institutions have filed patents on initial compound discovery, while firms have sought broader claims for formulation or method-of-treatment applications.
How Does US Patent 11,160,804 Fit Within Existing Patents?
- The patent builds on prior art by claiming specific structural modifications distinguished from earlier compounds.
- It does not claim the broad class of compounds but rather a subset with particular substitutions, narrowing its scope.
- In the context of existing patents, it potentially extends the patent life cycle of a drug candidate by covering a new formulation or use method.
What Are the Challenges in Patentability and Enforcement?
- Novelty hinges on the chemical structure’s specific substitutions and their unexpected pharmacological effects.
- Inventive step demands showing significant improvement over prior compounds; patent examiners scrutinize close structural analogs.
- Enforcement challenges include patent infringement disputes with third-party generic manufacturers, especially if claims are narrow or if prior art references exist.
