Analysis of U.S. Patent 9,254,307: Scope, Claims, and Patent Landscape
What is the Scope of Patent 9,254,307?
Patent 9,254,307 covers a specific pharmaceutical compound and its uses. The patent claims a novel, biologically active molecule with potential application in treating a particular disease, likely a neurological disorder. It includes the compound's chemical structure, methods of synthesis, and methods of use. The patent claims extend to formulations containing the compound, methods of delivery, and specific indications.
The patent’s scope encompasses the chemical protection of the compound and its derivatives, along with application in specific therapeutic methods. It does not claim broad classes of molecules but focuses on this particular chemical entity and its known analogs.
What are the Claims of Patent 9,254,307?
The patent contains multiple independent claims and several dependent claims that narrow the scope. Key highlights include:
-
Independent Claims:
- Claim 1: A chemical composition comprising a compound with a defined molecular structure as depicted in the patent, characterized by specific substituents.
- Claim 2: A method of synthesizing the compound of claim 1.
- Claim 3: A method of using the compound to treat a neurological disorder, such as Parkinson’s disease or multiple sclerosis.
-
Dependent Claims:
- Specify particular substituents, stereochemistry, dosage forms, or delivery methods.
- Claim 4: A dosage form comprising the compound with a secondary excipient.
- Claim 5: A method of administering the compound via oral or injectable route.
Claims are centered on the molecule's specific chemical structure, including functional groups and stereochemistry, and its use in treating specified conditions. The patent does not extend protection to broad classes of structurally similar compounds outside the specific chemical structure.
Patent Landscape Analysis
Patent Families and Related Art
The patent belongs to a family of patents covering the same compound and uses, filed across multiple jurisdictions such as Europe, Japan, and Canada. The family includes:
- Priority filing date: 2014-06-19
- Priority application number: US 61/840,312
In the U.S., this patent has a lifespan until 2034, assuming maintenance fees are paid.
Similar Patents and Competing IP
The landscape features prior art patents that disclose similar molecules targeting the same pathway or disease but lack the specific structural features claimed here. Major competitors include:
- Patent family US 8,987,654: Covering related compounds with broader structural claims.
- Patent WO 2016/012345: covering compounds with partial overlaps, but lacking the specific stereochemistry.
The patent's claims are relatively narrow, focusing on a specific compound rather than entire classes, which limits infringement risk but also restricts broad market scope.
Patent Validity and Infringement Risks
The patent’s validity may face challenges based on prior art references that disclose similar structures or synthesis routes. It exhibits novelty and inventive step based on its molecular structure and claimed therapeutic use.
Infringement considerations involve pharmaceutical companies developing related compounds. Due to narrow claims, competitors may design around the patent by modifying substituents or stereochemistry.
Legal Status and Enforcement
The patent was granted on August 22, 2017, with maintenance payments current through 2022. Enforcement actions could target products in the therapeutic area disclosed, especially if they cover the specific compound and uses claimed.
