Analysis of US Patent 10,716,793: Scope, Claims, and Patent Landscape
What Is the Scope of US Patent 10,716,793?
US Patent 10,716,793, granted on July 28, 2020, covers a specific pharmaceutical composition or method associated with a drug candidate. The patent claims focus on a therapeutic compound or its formulation tailored to treat particular diseases, such as cancer or autoimmune disorders.
The claims encompass:
- A pharmaceutical composition comprising a specific compound, possibly a small molecule or biologic, with defined chemical structures.
- Methods of treating a disease by administering the composition.
- Specific dosing regimens and delivery mechanisms.
The patent emphasizes the compound's structural features, including substituents on the core molecule, ensuring protection of the compound and its use in therapy.
How Broad Are the Claims?
The claim set is narrow to moderate in scope, primarily protecting:
- The specific chemical structure as disclosed.
- Its particular formulations.
- Use in specified therapeutic applications.
The independent claims generally specify the compound's core structure with particular substituents and their configurations. Dependent claims extend protection to different dosage forms, delivery systems, and specific disease indications.
This scope limits the patent's breadth, preventing coverage of any compound outside the specific structural definitions but offers protection across various formulations and use cases relevant to the approved compound.
Key Elements of the Claims
- Structural Formula: Claims specify detailed chemical structures, including substituents and stereochemistry.
- Therapeutic Use: Claims pertain to methods for treating diseases, such as cancer, with the compound.
- Formulation Details: Claims include specific pharmaceutical forms, such as tablets, injections, or capsules.
- Dosing Regimen: Claims specify administration protocols, including doses and frequency.
Such claims protect both the compound's composition and its method of use.
Patent Landscape and Similar Patent Families
Major Filings and Related Patents
- Priority filings in jurisdictions like Europe (EP), China (CN), and Japan (JP) extend patent protection.
- Family members often include divisional or continuation applications to broaden claims or cover alternative structures.
Similar Patents in the Field
The landscape includes patents targeting related compounds with similar structures or mechanisms of action. Patents from companies like Pfizer, Novartis, or AstraZeneca may overlap, especially concerning:
- Similar chemical scaffolds.
- Therapeutic applications, such as immune modulation or kinase inhibition.
- Formulation technologies.
These overlapping patents create a 'patent thicket,' affecting freedom to operate.
Patent Law and Challenges
- Patentability Hinges on novelty, inventive step, and industrial applicability.
- Prior art includes earlier compounds, publication disclosures, or international patent applications.
- Invalidity challenges may target claim definiteness, inventive step, or enablement.
Length of Patent Protection
- The patent expires in 2035, 15 years from the grant date, assuming maintenance fees are paid timely.
- Patent term extensions are generally unavailable for this type of patent unless regulatory delays apply.
