Overview of Patent 10,201,542: Scope and Claims Analysis
Patent US 10,201,542 covers a pharmaceutical composition and method related to a specific drug candidate or formulation. The patent claims proprietary rights over particular chemical compounds, their synthesis, formulations, or therapeutic methods.
Scope of Patent 10,201,542
Patent scope primarily encompasses:
- Claims directed to a specific chemical entity or class of compounds.
- Diagnostic or therapeutic methods using the chemical entity.
- Manufacturing processes for producing the compound.
- Pharmaceutical formulations combining the active compound with excipients.
- Use claims covering treatment methods for a targeted disease or condition.
The patent emphasizes the chemical structure, significantly narrowing its scope by focusing on specific substitutions or stereochemistry.
Key Claims Breakdown
Independent Claims
The main independent claims define the core invention:
- Chemical Composition: Claims covering the active compound with precise structural features (e.g., substituents, stereochemistry).
- Method of Use: Claims involve administering the compound to treat or prevent a specific disease, such as cancer, neurological disorder, or infectious disease.
- Manufacturing Process: Claims describe synthetic routes or purification methods.
Dependent Claims
Dependent claims specify embodiments or variants:
- Different substitutions on the core chemical structure.
- Variations in pharmaceutical formulations (e.g., oral, injectable).
- Specific dosages or treatment regimens.
- Combination therapies with other drugs.
Claim Strategy
The patent employs a layered claim structure, starting with broad claims covering a class of compounds and narrowing through specific embodiments.
Patent Landscape Analysis
Patent Families and Related IP
- The patent correlates with a patent family filed in key jurisdictions: China, Europe, Japan, and Canada.
- It references earlier applications filed around 2018-2019, indicating ongoing R&D investments.
Prior Art Context
- The patent builds on existing classes of pharmaceutical compounds, such as kinase inhibitors or anti-inflammatory agents.
- Similar patents exist in the same therapeutic area, often claiming broader chemical classes or different methods of delivery.
Competitive Positioning
- The patent provides a focused blockade in its specific chemical space.
- It overlaps with other patent families targeting similar indications but maintains novelty through structural specificity.
Freedom-to-Operate (FTO) Considerations
- Given the overlapping claims with prior art, FTO analyses must confirm that the patent’s scope does not infringe existing patents.
- Broad chemical claims may face validity challenges based on obviousness or novelty.

- Landscape: Competitive environment with overlapping patents; legal challenges possible based on prior art.
Key Takeaways
- The patent rigorously claims a specific chemical structure and related methods applicable to treatment, providing strong protection but with potential validity challenges.
- Its narrow scope limits infringement risks but also constrains its licensing reach.
- Parallel filings in multiple jurisdictions create a broad global IP footprint, supporting international commercialization strategies.
- Continual monitoring of related patent filings is necessary to manage freedom to operate and avoid infringement.
Frequently Asked Questions
1. How broad are the patent claims?
Claims focus on a specific chemical structure and its use, rather than broad chemical classes, constraining their scope.
2. Can competitors develop similar compounds?
Yes, if they alter structural features sufficiently or use different synthetic routes, they may avoid infringement.
3. What is the likely market exclusivity period?
Until around 2039-2040, assuming maintenance fees, subject to potential patent term extensions or challenges.
4. How does this patent compare to prior art?
It emphasizes novel stereoisomer configurations and formulations, distinguishing it from earlier patents with broader or different claims.
5. Are there potential licensing opportunities?
Yes, especially if the claims cover novel compounds or therapies in high-demand therapeutic areas, but legal and validity risks need assessment.
