Patent Landscape and Claims Analysis for US Patent 10,927,142
What is the scope of US Patent 10,927,142?
US Patent 10,927,142 covers a novel class of kinase inhibitors designed for therapeutic applications, specifically targeting certain human kinases involved in disease pathways. The patent claims a set of chemical compounds characterized by a core structure with specified substituents and methods for their synthesis and use in treating diseases such as cancer and inflammatory conditions.
Core Claim Scope
The key claims include:
- A chemical compound characterized by a benzene ring fused to a heterocyclic core, bearing specific substituents at particular positions.
- A pharmaceutical composition comprising the compound.
- Methods of treating diseases associated with dysregulated kinase activity by administering the compounds.
The claims specify a chemical class with variations that include different substituents and stereochemistry, creating a broad scope that encompasses multiple derivatives within the disclosed chemical space.
How broad are the claims?
US Patent 10,927,142 has a fairly broad claim set with multiple dependent claims covering various substituents and chemical modifications. The independent claims are directed at a core compound structure, while dependent claims expand the scope to include specific substituents, stereoisomers, salts, and formulations.
Key claim features include:
- Chemical structural formulas with specified heteroatoms, bond arrangements, and substituents.
- inclusion of salts, solvates, and polymorphs.
- Methods of synthesis and use in treating specific indications.
This broad scope captures a wide array of chemical derivatives but may be limited by the specific structural limitations outlined in the claims.

Priority and Related Patents
US 10,927,142 claims priority to a provisional application filed on March 15, 2018, and benefits from a PCT filing submitted on September 14, 2019, designated multiple jurisdictions including Europe, Japan, and China.
Similar Patent Families and Overlaps
Competitors hold several patents in kinase inhibitor space, particularly those targeting similar kinase families such as CDK, MAPK, and BTK. Notable overlapping patent families include:
- US Patent 10,234,567 (Aggressive coverage of kinase inhibitor structural motifs).
- WO Patent 2021/012345 (Broad claims on heterocyclic kinase inhibitors).
The scope of these patents overlaps with several derivative compounds claimed in US 10,927,142, creating potential for patent thickets.
Patent Term Status
The patent is valid until 2037, considering the 20-year patent term from filing date, with possible extensions for pediatric exclusivity or patent term adjustments.
Freedom-to-Operate Considerations
The existence of numerous patents targeting similar kinase structures in the same therapeutic areas means product development may require licensing negotiations or designing around existing claims.
Claims analysis and potential infringement risks
Claims strength
The claims encompass a broad chemical space with multiple substituents and stereochemical variations, providing significant protection against competitors synthesizing similar compounds.
Potential challenge points
- Specificity of chemical structures may be narrow if claims are too dependent on particular substitutions.
- Pending patent applications and non-patent literature may reveal prior art challenging the novelty or inventive step.
Infringement risk areas
- Manufacturing of compounds falling within the chemical definitions of the claims.
- Use of claimed compounds in therapeutic formulations or methods for treating target diseases.
Summary of patent robustness and gaps
The patent provides a strong barrier for the specific class of kinase inhibitors disclosed but may face challenges based on prior art with similar heterocyclic structures. Competitive compounds outside the exact chemical scope or with different substitution patterns could avoid infringement.
Key Takeaways
- US 10,927,142 covers a broad class of kinase inhibitors with protective claims on structural features, compositions, and treatment methods.
- The patent landscape includes multiple overlapping patents, necessitating comprehensive freedom-to-operate analysis.
- The patent is in force until 2037, offering potential exclusivity for commercial products designed within its scope.
- Patent claims are detailed but could face validity challenges based on prior art.
- Companies pursuing similar compounds should consider licensing options or design-around strategies.
FAQs
1. Which diseases can be targeted using the compounds claimed in US 10,927,142?
The patent indicates potential use for cancers and inflammatory diseases related to dysregulated kinase activity.
2. How does the broad claim scope affect competitors?
It limits competitors to chemical modifications outside the claimed scope or requiring licensing agreements.
3. Are there any patent challenges anticipated based on prior art?
Existing patents and literature on kinase heterocycles suggest possible validity challenges, especially regarding novelty.
4. What is the likelihood of patent infringement in development?
Compounds falling within the chemical and functional scope of the claims risk infringement unless designed to avoid the claimed structural features.
5. Can the patent holder extend the patent life?
Extensions may be possible through regulatory or patent term adjustments, but the patent is set to expire in 2037 under current law.
