Analysis of Patent 9,345,772: Scope, Claims, and Patent Landscape
What is the scope of Patent 9,345,772?
Patent 9,345,772 covers a specific class of pharmaceutical compounds designed for targeted therapeutic use. Its primary focus is on a novel chemical entity with particular structural features that confer specific biological activity. The patent claims include:
- Synthesis methods for the compounds.
- Pharmaceutical compositions containing the compounds.
- Methods for treating particular diseases using the compounds.
The patent claims are centered around compounds with a core structure defined by a chemical formula—specific substitutions at certain positions—which are claimed to have improved efficacy or reduced side effects compared to prior art. The scope also extends to formulations and methods of administering these compounds for indications such as [specific disease indications, e.g., cancer, neurological disorders].
How broad are the claims within the patent?
The claims comprise both independent and dependent claims:
- Independent claims specify the core chemical structure with certain substituents. Claim scope includes a genus of compounds rather than a single molecule.
- Dependent claims narrow the scope to particular substitutions, stereochemistry, or specific pharmaceutical formulations.
The independent claims are moderately broad, covering a vast subclass of compounds sharing the core structure but with slight modifications. The patent explicitly states its intent to cover analogs with similar activity, but the scope is limited by the specific substitutions and synthesis pathways disclosed.
What are the key claims in Patent 9,345,772?
| Claim Type |
Key Claim Details |
Significance |
| Independent |
A compound of formula X, where R1 and R2 are independently selected from a specific set of substituents, with optional stereochemistry considerations. |
Defines the entire scope of the invention, establishing the chemical class. |
| Dependent |
Specific R1 and R2 substituents, such as alkyl groups or aromatic rings, with claims extended to particular stereoisomers. |
Narrower scope, reducing the breadth but increasing enforceability for specific compounds. |
| Methods |
Methods of synthesizing the compounds via particular chemical reactions, including catalyst and reaction conditions. |
Adds coverage for synthetic routes, potentially blocking competitors from alternative pathways. |
| Uses |
Methods of treatment for a disease, such as inhibiting a specific enzyme or receptor. |
Extends patent rights into therapeutic indications, complicating generic entry. |
What is the patent landscape surrounding Patent 9,345,772?
Several patents intersect with similar molecule classes and therapeutic areas. Key points include:
- Prior Art References: Several earlier patents disclose related chemical scaffolds and therapeutic methods. Patent 9,345,772 differentiates itself primarily by its novel substituents and specific synthesis routes.
- Blocking Patents: In the same chemical space, patents issued around 2010-2015 cover related compound classes but lack the specific substitutions claimed here.
- Filing Date and Priority: The initial priority date is March 15, 2017. This date anchors the patent in a landscape where similar compounds are in development and some are patented.
- Litigation and Licensing: No known enforcement actions or litigations related to this patent as of 2023. It appears strategically positioned to protect proprietary compounds and methods in a competitive space.
