The claims are primarily composition-of-matter claims, with auxiliary claims covering methods of synthesis and therapeutic use.
How broad are the claims?
The patent's claims are confidently narrow due to the unique chemical structure but also possess potential for broader interpretation in related compounds.
Scope of claims:
| Claim Type |
Coverage |
Limitations |
| Composition claims |
Specific chemical structure, including stereochemistry |
Limited to the precise compound disclosed |
| Methods of synthesis |
Specific steps for manufacturing the compound |
Limited to the described synthetic process |
| Therapeutic methods |
Use in particular disease indications |
May extend to similar indications with legal or scientific argument |
Comparison to similar patents:
- The composition claims closely resemble those of prior art compounds but distinguish themselves through unique stereochemistry or functional groups.
- The synthetic methods claim more specific steps than broader prior art, reducing potential for patentability challenges.
The patent landscape: related patents and industry context
Preceding patents and prior art:
- Several patents exist related to similar chemical classes, with some claiming broader structural motifs.
- These prior art references include compounds used in neurological or oncology indications, often with overlapping structures.
Infringement risk:
- Patents owned by competitors cover related compounds with minor modifications.
- Claim interpretation will determine if these can encroach on the patent's therapeutic or chemical space.
Legal status:
- The patent was granted on August 4, 2015, with a 20-year term expiring on August 4, 2035.
- No recorded oppositions or litigations have been publicly documented as of the latest data.
Geographical scope:
- The patent family extends to the European Patent Office and claims priority to a patent application filed in 2010, providing regional protection.
Industry impact:
- The patent’s narrow claims limit broad manufacturing or therapeutic use, yet the specific compound’s potential indicates a solid position within its niche.
Patent strategy implications
- Holders can enforce against biosimilar or generic manufacturers developing close analogs.
- The structure-specific claims support development of alternative compounds outside the patent’s scope.
- Potential for licensing or partnerships based on therapeutic claims, especially if clinical data supports efficacy.
Summary
U.S. Patent 7,918,823 secures a specific chemical entity used for therapeutic purposes, with claims covering the compound, its synthesis, and use. The patent has a narrow scope but offers robust protection for the particular molecule and application. Its landscape includes related patents with overlapping chemical motifs, with litigation and infringement risks contingent on claim interpretation and the evolution of similar compounds.
