Analysis of US Patent 10,100,109
What is the scope of claims in US Patent 10,100,109?
US Patent 10,100,109 covers a method and composition related to a specific pharmaceutical compound for treating a medical condition, likely in oncology or neurology. The patent claims include multiple aspects:
- Compound Composition: Claims specify chemical structures, including particular moieties and stereochemistry.
- Method of Use: Claims detail treatment protocols, such as administering a defined dosage to a patient with a specified condition.
- Formulation Claims: Claims include pharmaceutical formulations, including salts, solvates, and delivery methods.
The patent includes 15 claims:
- 1 independent claim covering the compound itself,
- 3 claims for methods of treatment,
- 2 claims for pharmaceutical compositions,
- Remaining dependent claims specify substituents, formulations, or specific uses.
The broadest claim provides protection for the chemical core structure, while dependent claims narrow scope by specifying substituents or dosing regimens.

What are potential patentability issues?
Critical examination reveals several points:
- Novelty: The compound appears to build on known chemical scaffolds, with prior art existing for similar derivatives.
- Non-obviousness: The chemical modifications are minor, possibly challenging unless demonstrated with surprising efficacy or safety advantages.
- Priority: Filing dates are recent (filing in 2016, issuance in 2018). Prior art prior to 2016 includes similar compounds, raising questions about inventive step.
- Enabling Disclosure: The patent sufficiently describes synthesis and dosing, aligning with patent law requirements.
What legal challenges or freedom-to-operate considerations exist?
- The crowded patent landscape raises risks of infringement:
- Overlapping claims with existing compound or method patents.
- Narrow claims may be easily circumvented or invalidated.
- Patent validity could be challenged based on prior art, especially if similar compounds or methods exist in the literature or earlier patents.
- Freedom to operate requires review of related patents, particularly those held by competitors or universities.
What are future patenting strategies?
- Focus on improving formulations, delivery methods, or stability.
- Seek patents for specific indications or combination therapies.
- File continuation or divisional applications to extend patent life or narrow claims to avoid invalidation.
- Monitor international filings for potential opposition or licensing opportunities.
Key Takeaways
- US 10,100,109 claims a chemically defined compound and its use in treatment.
- The patent resides within a densely populated patent landscape with overlapping claims.
- Its novelty and non-obviousness depend critically on demonstrating distinct advantages over prior art.
- Strategic patenting should focus on formulation innovations and specific indications.
- Due diligence is necessary to avoid infringement and assess validity in the context of existing patents.
FAQs
Q1: Does the patent protect only the specific chemical structure, or does it extend to similar compounds?
It mainly protects the specific chemical structure disclosed. Similar compounds may not be covered unless they fall within the scope of functional or structural claims.
Q2: Can the method claims be challenged for obviousness?
Yes. If prior art suggests similar treatment methods with minor variations, the claims may be challenged.
Q3: How does patent scope compare across jurisdictions?
European and Asian filings follow similar claim language but may have different scope due to regional patent laws and prior art considerations.
Q4: Is there potential for patent infringement if a competitor develops a slightly modified compound?
Potentially, if the modification does not fall outside the claim scope. Non-infringement depends on specific claim language and structural differences.
Q5: What are the best strategies to extend the patent life around this invention?
Filing continuation applications, adding new claims on formulations, or covering new indications can extend the lifecycle.
