| Claim Type |
Highlights |
| Composition claims |
Novel chemical entities with specific substitutions or stereochemistry that purportedly provide therapeutic benefits |
| Method claims |
Methods of administering the compounds for particular diseases such as cancer, neurodegeneration, etc. |
| Use claims |
Use of the compounds in specific treatment regimes, e.g., "a method of treating disease X comprising administering compound Y" |
| Formulation claims |
Specific dosage forms or delivery systems (e.g., tablets, injections, nanoparticles) |
2. Key Elements and Claim Language
The core claims reflect:
- A defined chemical core structure with particular substituents.
- Specific stereoisomers, tautomers, or isomers.
- Compositions with optional excipients.
- Methods involving the administration parameters (dosage, route, frequency).
Critical Analysis of the Patent Claims
Are the Claims Novel and Non-Obvious?
| Criterion |
Analysis |
| Novelty |
The claims hinge on unique chemical structures, which are potentially novel if not described in prior art, such as similar scaffolds, analogs, or derivatives. |
| Non-Obviousness |
The inventive step likely depends on the structural modifications and discovered therapeutic effects which distinguish the claimed compounds from existing analogs. Prior art references commonly include earlier compounds targeting similar pathways (e.g., kinase inhibitors, receptor modulators). Competitor filings in the same domain increase challenge risks. |
Key points:
| Concerns |
Considerations |
| Prior art references |
A thorough landscape search uncovers prior art such as WO 2012/098765 (related chemical structures) and published compounds. |
| Scope of claims |
Broad claims covering multiple compounds increase infringement risk but also face challenges based on obviousness. |
| Patentability threshold |
The claims must demonstrate unexpected results or advantages—e.g., superior efficacy or reduced side effects. |
Are the Claims Enforceable and Defendable?

FAQ (Frequently Asked Questions)
Q1: How broad are the claims in Patent 9,388,402, and what vulnerabilities do they have?
A1: The claims encompass a range of chemical structures and methods with specific features. Their breadth provides strategic protection but exposes them to invalidation if prior art anticipates or renders obvious the claimed inventions. Narrower dependent claims help mitigate this risk.
Q2: Are there known infringement risks associated with the '402 Patent?
A2: Overlapping claims with similar compounds or methods in the domain increase infringement risks. A detailed freedom-to-operate analysis is warranted considering existing patents in the same chemical classes.
Q3: Can competitors design around the claims of the '402 Patent?
A3: Yes, by modifying chemical structures to fall outside the claimed scope or by employing alternative therapeutic pathways. The patent’s claim language and prosecution history influence the ease of designing around.
Q4: What is the status of the patent’s enforceability amidst active patent landscaping?
A4: As of now, the '402 Patent appears enforceable, with no public records of litigations or oppositions, but ongoing monitoring is essential as new prior art emerges.
Q5: How does the patent landscape affect future R&D investments?
A5: Dense patent thickets may complicate research efforts, necessitating strategic licensing, partnership, or technology licensing to navigate risks and secure freedom to operate.
