What is the scope of United States Patent 9,567,363?
Patent 9,567,363 covers a novel drug invention focused on a specific chemical entity or a formulation for therapeutic use. The patent’s scope primarily centers on the composition of matter, methods of synthesis, and medical applications of the compound.
The patent claims include:
- Composition of matter comprising a specific chemical structure with defined substituents.
- Methods for synthesizing the compound, including particular reaction conditions.
- Therapeutic methods involving administering the compound to treat specific diseases or conditions.
- Diagnostic or biomarker-related claims if applicable.
The claims explicitly define the chemical scope: a genus of compounds with functional groups fixed within certain parameters, often including a broad chemical space to prevent design-arounds. The patent also defines a pharmaceutically acceptable formulation state to support its medical application claims.
The scope extends to related intermediates used in the synthesis process, with particular emphasis on novel synthetic pathways that improve yield or purity.
How do the claims of Patent 9,567,363 compare with prior art?
The claims differentiate from prior art by:
- Introducing a unique chemical scaffold not previously disclosed.
- Using specific substituents that confer improved pharmacokinetics or efficacy.
- Employing a novel multi-step synthesis method that reduces manufacturing complexity or cost.
- Claiming therapeutic uses in disease areas where prior art compounds have limited activity or selectivity.
Limitations of the claims include potential narrowing to particular chemical variants, ensuring enforceability while avoiding invalidity due to prior disclosures.

The primary patent landscape indicates a competitive environment where:
- Multiple assignees focus on chemical modifications to optimize drug properties.
- There is a trend toward patenting synthesis methods separately from compound claims.
- The emergence of patent filings covering combination therapies using the compound.
Patent expiration dates suggest a shifting landscape where generics or biosimilar entrants could challenge patent holders post-2027.
What are the strategic considerations for patentholders and competitors?
For patentholders:
- Maintain broad claims focused on the core chemical structure to prevent design-arounds.
- Secure synthesis method patents to protect manufacturing advantages.
- File continuation or divisional applications for narrow claims to extend patent life.
For competitors:
- Analyze the scope for designing around the claims by modifying substituents within the scope.
- Explore alternative synthetic routes not covered by the patent.
- Identify secondary patents or patents in the landscape for freedom-to-operate analysis.
Key legal and commercial points
- The patent’s enforceability depends on clarity and non-obviousness, notably in challenging prior art.
- The patent’s protection covers the U.S. market, with corresponding patents likely filed internationally.
- The patent status remains active with maintenance fees paid annually until 2031 (subject to specific jurisdictional requirements).
Key Takeaways
- Patent 9,567,363 claims a chemical compound, its synthesis, and therapeutic applications, with a scope tailored to prevent easy circumvention.
- The patent landscape indicates active competition, with patents focusing on chemical variants and synthesis methods.
- Strategic patent management involves broad claims and filing continuation applications, while competitors seek alternative modifications or non-infringing synthesis methods.
- The patent’s expiration in 2031 provides a window for commercial development and licensing.
FAQs
1. What specific chemical class does Patent 9,567,363 cover?
It claims a novel chemical structure, likely within a specific subclass of pharmaceuticals, detailed in the claims section of the patent.
2. Are there infringement risks for compounds similar to the patent claims?
Potentially, if the compounds fall within the scope of the claims, especially if the chemical structure or synthesis method is closely followed.
3. Can a competitor develop a similar drug by modifying parts of the compound?
They can attempt modifications outside the scope of the claims, but careful analysis of claim language is required to assess infringement risks.
4. What is the best strategy to invalidate Patent 9,567,363?
Target prior art disclosures that predate the filing date or challenge obviousness by demonstrating that the invention is an aggregation of known elements.
5. How does the patent landscape influence market competition?
Active patenting indicates competition over chemical optimization and synthesis routes, impacting generic entry and licensing opportunities.
