Patent 9,157,082 Analysis: Scope, Claims, and Landscape

What are the scope and claims of Patent 9,157,082?

Patent 9,157,082 covers a specific chemical compound classified as a kinase inhibitor, designed for therapeutic use in treating various cancers. The patent claims focus on the compound's chemical structure, methods of synthesis, and methods of treatment.

Key Claims

• Chemical structure: Claims encompass compounds with a core structure similar to 4-(2,4-dichloro-phenylamino)-7-(piperazin-1-yl)-quinazoline derivatives, including specific substitutions.
• Method of synthesis: Provides detailed synthesis pathways for the claimed compounds.
• Therapeutic application: Claims include methods for treating cancers such as non-small cell lung cancer (NSCLC), breast cancer, and other solid tumors using the compounds.

Scope of Claims

• The claims are directed towards a genus of compounds, with some claims narrowing to specific substitutions and methylation variants.
• Use claims cover administering the compounds for cancer therapy, including oral and injectable forms.
• The patent explicitly claims methods of treatment involving these compounds.

Limitations

• The claims do not extend to compounds outside the specified chemical core or with different heterocyclic substitutions.
• The patent also excludes compounds with specific reactive groups or substitutions as detailed in dependent claims.

Analyzing the patent's validity and potential challenges

Prior Art

• Prior patents and publications predate 2014 and describe similar kinase inhibitors.
• The scope of claims in 9,157,082 is narrowed to specific substitutions, reducing overlap with broader prior art but still vulnerable to challenge on obviousness.

Patent Term

• Filed in 2014; expected expiry in 2034, subject to patent term adjustments.
• Protects the compound and methods of treatment in the US for 20 years from filing.

Innovation and non-obviousness

• The patent claims incremental modifications over prior art compounds.
• Novelty lies in particular substitutions that improve selectivity or pharmacokinetics, but similar compounds are known.

License and litigation landscape

• No notable litigation specific to 9,157,082 reported as of now.
• Licensing activity increases, especially in indication-specific collaborations.
