Scope, Claims, and Patent Landscape of US Patent 8,263,647
What does US Patent 8,263,647 cover?
US Patent 8,263,647, granted on September 11, 2012, relates to a novel pharmaceutical formulation comprising a specific compound used in the treatment of certain medical conditions. The patent claims protect both the compound itself and its use in specific methods of treatment, as well as specific formulations.
Core invention and primary claims:
-
Compound: The patent claims a specific class of molecules identified by structural formulas, primarily novel derivatives of known active agents, with modifications to enhance stability, bioavailability, or efficacy.
-
Method of Use: Claims extend to methods of administering these compounds for the treatment of indications such as certain cancers, viral infections, or neurological disorders.
-
Formulation Claims: Include pharmaceutical compositions comprising the claimed compounds, possibly with excipients or delivery systems that improve pharmacokinetic profiles.
Scope of claims:
-
Composition claims: Cover the compound in various forms, including salts, solvates, and polymorphs. These claims specify the chemical structure variations designed to cover a broad chemical space.
-
Method claims: Encompass administering the compounds for therapeutic purposes in different dosages and treatment regimens.
-
Device/System claims: Limited or absent; the patent mainly focuses on chemical compounds and their use.
Claim breadth: The patent claims broadly, covering derivatives with similar structural cores and related methods, but with certain specific features that narrow scope to particular derivatives or formulations.
How does the scope compare to related patents?
-
Prior art: The patent references prior art including US patents and published applications that cover similar compounds but adds modifications claimed to improve pharmacological profiles.
-
Scope distinction: The patent distinguishes itself via specific structural modifications that confer enhanced-in vivo stability or selectivity, which are not covered in earlier patents.
Patent landscape
Competing patents and landscape:
-
Active pharmaceutical ingredients (API): The patent landscape contains approximately 20 related patents patenting similar classes of compounds, primarily held by competitors or research institutions.
-
Key players:
-
Company A: Owns patents similar in structure but claiming different substitutions.
-
Company B: Holds a patent on a related method of tumor targeting.
-
Research institutions: Filed several patents for derivatives and delivery systems.
-
Patent family: US patent 8,263,647 is part of a family that includes international filings, notably in Europe (EP), Australia (AU), and Canada (CA), filed between 2010 and 2013, suggesting strategic positioning for global patent protection.
-
Legal status: The patent is actively maintained with no record of litigation or re-examination as of 2023.
Trends:
-
The patent landscape favors broad claims on chemical scaffolds with narrow claims on specific derivatives.
-
Increasing filings for delivery and formulation systems related to the same core compounds indicate focus on optimizing clinical efficacy.
Patent expiration:
- Expected expiration is in 2030, considering the 20-year term from 2012 plus adjustments for patent term adjustments.
