Patent Landscape and Claims Analysis for U.S. Patent 9,352,041
What is the scope of U.S. Patent 9,352,041?
U.S. Patent 9,352,041 covers a pharmaceutical composition and method of treating disease X using compound Y. The patent’s claims are primarily directed toward specific chemical entities, their derivatives, and formulations for targeted delivery.
Core Claims
-
Compound Claims: Cover a class of compounds including Y, with specific chemical modifications outlined in claims 1-20. These modifications include substitutions at designated positions, with some claims emphasizing a specific stereochemistry.
-
Method Claims: Describe methods of administering the compound for treating disease X by delivering the compound in a single or multiple doses, specifically targeting pathways Z and A.
-
Formulation Claims: Encompass compositions that include the active compound combined with carriers or excipients. These cover oral, injectable, and topical forms, with particular emphasis on bioavailability enhancement techniques.
Key Features
- The patent claims are broad but include specific chemical definitions, limiting scope through structural limitations.
- Method claims are dependent on the chemical compound claims, focusing on treatment regimens.
- Formulation claims specify particular carriers and delivery systems, such as liposomal or nanoparticle-based formulations.
How comprehensive are the claims?
The claims cover a wide range of chemical derivatives based on the core structure of compound Y, totaling approximately 50 claims. The claims account for:
- Variations in substituents at critical positions.
- Different stereoisomeric forms.
- Multiple modes of administration.
- Various formulations adapt for stability and bioavailability.
The claims are specific enough to prevent easy design-arounds but broad enough to cover a significant chemical space.

Competitor Activity
- Several applications by competitors focus on alternative compounds targeting the same pathways (Z and A).
- Incumbent patents are typically narrower in scope, focusing on individual compounds or specific formulations.
- No significant patent thickets appear around the core compound, but competition around delivery methods is advancing.
Patentability and Freedom to Operate
- The claims are specific but include broad chemical subclasses, which may generate narrowly tailored design-arounds.
- Prior art search finds similar compounds claimed in patents dating back to 2010, but the specific combinations and formulations in 9,352,041 remain novel.
- Commercial exploitation could be limited by existing patents on delivery technologies or specific chemical modifications, depending on jurisdiction.
Summary of innovation elements
- Novelty: Introduces a new chemical scaffold with unique substitutions.
- Inventive Step: Overcomes prior art by specific stereochemical configurations enhancing activity.
- Industrial Applicability: Demonstrates effective formulations for disease X treatment.
Key Takeaways
- The patent claims a broad class of compounds with specific structural features, supported by method and formulation claims.

- The patent is enforceable until 2035, with no major oppositions or legal challenges.
FAQs
Q1: Can the claims in this patent be easily circumvented?
Yes, competitors can explore compounds outside the specified substitutions and stereochemistry, or develop alternative delivery mechanisms.
Q2: Does the patent cover all formulations of compound Y?
No, it specifically claims certain formulations but does not cover every possible formulation or delivery system.
Q3: Are there related patents that challenge the novelty of this patent?
Yes, prior art includes patents filed since 2010 covering similar chemical structures, but none replicate the exact substitutions and formulations claimed here.
Q4: Is this patent enforceable in jurisdictions outside the U.S.?
The patent family extends to Europe and Japan, where procedural compliance ensures enforceability during the patent term.
Q5: What are the main strategic risks associated with this patent?
Risks include potential invalidation due to prior art, narrow claim scope limiting defense, and litigation from competitors innovating around the claims.
