Overview of U.S. Patent 10,478,400
U.S. Patent 10,478,400 covers a specific compound, formulation, or method for treating a medical condition. It was granted on November 12, 2019, assigned to a pharmaceutical company, and relates to novel therapeutics likely involving a chemical entity, pharmaceutical composition, or a method of administration.
What Is the Scope of the Patent?
The patent's scope centers on protecting a particular chemical compound or class of compounds, along with their pharmaceutical formulations and methods for their use. The claims typically include:
- Compound Claims: Cover the novel chemical structure or derivatives, including salts and esters.
- Method Claims: Describe therapeutic methods, such as administration to treat specific diseases.
- Formulation Claims: Include dosage forms, excipients, or delivery mechanisms.
- Use Claims: Cover the use of the compound for treating specific indications, e.g., a disease or condition.
The patent aims to prevent competitors from manufacturing, using, or selling identical or similar compounds or methods within its claims' scope.
Claims Analysis
The patent includes primary, secondary, and possibly dependent claims divided as follows:
- Independent Claims: Define the core invention, such as a chemical compound or a therapeutic method. Typically, they specify the chemical structure, substituents, and variants.
- Dependent Claims: Add specifics, such as particular salts, formulations, dosages, or treatment protocols, narrowing the focus.
For U.S. Patent 10,478,400:
- The compound claims likely specify a novel chemical entity characterized by particular functional groups or substitutions.
- The method claims probably cover administration to treat diseases like cancer, neurological disorders, or other conditions, with claims detailing dosing regimens, frequency, or combination therapy.
- The formulation claims may detail specific dosage forms like oral tablets, injections, or topical preparations.
Claim scope generally aims to balance broad coverage—preventing minor modifications—and specificity to avoid invalidation by prior art.
Patent Landscape and Related Patents
The patent landscape includes:
- Prior Art References: Similar chemical entities or therapeutic methods published before 2019.
- Subsequent Patents: Follow-up patents related to formulations, delivery systems, or combination therapies referencing or citing the 10,478,400 patent.
- Patent Families and Continuations: Related patents filed internationally or as continuation-in-part applications, expanding protection beyond the original claims.
Competitive landscape:
- Major pharmaceutical companies and biotech firms working on similar therapeutic targets have likely filed patents seeking overlapping claims.
- Patent databases such as USPTO, EPO, and WIPO reveal a concentration of patents on the same chemical class or medical indication.
