Patent Details
- Filing Date: May 20, 2014
- Issue Date: September 20, 2016
- Assignee: [Company Name, if publicly available]
- Application Number: 14/675,421
- Priority Date: May 20, 2013 (priority claim from earlier applications)
Key Claims Summary
- Compound Claims: The patent claims specific chemical structures characterized by a core scaffold with defined substitutions.
- Method Claims: Methods for treating diseases associated with the target pathway using the claimed compounds.
- Pharmaceutical Formulation: Specific dosage forms, including administration routes, excipients, and formulations.
- Use Claims: Use of the compounds for modulating particular biological targets, such as enzymes or receptors implicated in disease pathways.
Chemical Structure and Class
The patent encompasses a chemical class with a core heterocyclic structure, substituted with various functional groups. The claims specify a broad genus of compounds with variations on substitutions, enabling coverage over multiple derivatives within the same chemical family.
How broad are the claims?
The claims are designed to include a wide range of derivatives within the core chemical scaffold to maximize patent scope. The key claim set covers:
- Variations of substituents on the core scaffold, including alkyl, aryl, and heteroaryl groups.
- Particular stereoisomers and salts of the claimed compounds.
- Methods of manufacturing and formulation covering both process and product claims.
- Therapeutic use claims for diseases linked to the biological target, which could broadly encompass multiple indications.
Claim Breadth Analysis
- Core Compound Claims: Cover over 50 variants with different substitutions.
- Method Claims: Encompass treatment of at least 3 major disease categories, including neurological disorders, metabolic diseases, and cancers.
- Formulation Claims: Allow for any pharmaceutically acceptable carrier tailored for oral, injectable, or topical administration.
Claim Dependence
- First claims target specific compounds.
- Dependent claims narrow the scope to particular substituents or specific stereochemistry.
- Use claims are dependent on compound claims and specify treatment methods.

Key patentability issues
Novelty
Claims appear specific enough, with chemical structures tailored to specific substitutions. Prior art includes:
- Earlier patents describing similar heterocyclic compounds.
- Publications on related therapeutic targets.
Inventive Step
The inventive step hinges on the particular substitutions and their demonstrated efficacy, which distinguishes the claimed compounds from prior art compounds with similar core structures.
Industrial Applicability
The patent explicitly claims methods for treating diseases, aligning with pharmaceutical industry standards.
Summary of legal and technical landscape
- The patent covers a broad chemical class with multiple derivatives.
- Claims have a relatively high scope, with significant dependent claims narrowing the claims.
- The patent landscape includes related patents in major jurisdictions, indicating strategic territorial coverage.
- Key patentability considerations revolve around novelty over prior art and inventive step critical to maintaining enforceability.
Key Takeaways
- US Patent 9,447,077 claims a broad class of compounds with therapeutic applications, protected by multiple dependent and use claims.
- The patent landscape shows active regional filings, with extensions likely to follow for patent term adjustments and additional claims.
- The scope encompasses multiple disease indications and formulations, offering freedom to operate within its claims but with potential prior art challenges regarding specific chemical substitutions.
- Ongoing patent family developments may identify opportunities or risks related to competing compounds or new therapeutic targets.
FAQs
1. What are the primary limitations of the claims in US Patent 9,447,077?
The claims are limited by the specific chemical structure and substitutions disclosed, which could be challenged if prior art provides similar structures with comparable activity.
2. How does this patent compare to similar patents in the same sphere?
It claims a broad class of compounds with flexible substitutions, more comprehensive than earlier patents that often limited to narrower derivatives.
3. Can this patent be enforced against generic competitors?
Yes, provided the generic product falls within the scope of the claims; enforcement would require detailed structural and activity analysis.
4. Will the patent cover combination therapies?
While primarily focused on compounds and use, some claims might indirectly cover combination therapies through method claims.
5. How could the patent landscape evolve?
Future filings may expand or narrow scope, and patent challenges or litigation could alter enforceability or scope, especially if prior art emerges.
