Patent 11,744,802: Scope, Claims, and Landscape Analysis
What Does Patent 11,744,802 Cover?
Patent 11,744,802, granted by the United States Patent and Trademark Office (USPTO) in 2023, protects a novel small-molecule drug candidate. The patent claims include both composition of matter claims for the molecule itself and method claims for its therapeutic use. The patent’s scope targets indications in oncology, specifically solid tumors, with potential extensions into other inflammatory and autoimmune disorders.
Key Elements of the Patent
- Chemical Structure: The core compound comprises a heterocyclic scaffold with defined substituents. Its structure is designed to inhibit specific kinase pathways associated with tumor proliferation.
- Indications: The patent explicitly mentions treatment of various cancers, including lung, breast, and pancreatic cancers, with the possibility of broader application.
- Administration Routes: Oral and injectable formulations are claimed, broadening potential product development.
- Methods of Use: Claims cover both the use of the compound alone and in combination with other chemotherapeutic agents.
Patent Claims Breakdown

Claims are broad, yet specific to the chemical structure. The composition claims are narrow enough to avoid prior art around similar kinase inhibitors but broad enough to cover variations in substituents.
Patent Landscape Analysis
Related Patent Families
The patent family includes filings in major jurisdictions: Europe (EP), Japan (JP), China (CN), and Canada (CA). No previous patents directly cover this molecule, but prior art in kinase inhibitors provides some context.
Competitive Environment
- Major Players: Several pharmaceutical companies and biotech firms hold patents around kinase inhibitors targeting similar pathways, notably in the US, Europe, and Asia.
- Patent Overlap: US Patent 11,744,802’s structure overlaps with compounds claimed in prior patents such as US 10,856,789. However, the specific substitutions and synthesis methods distinguish it.
- Litigation & Litigation Risk: No current litigation related to this patent; however, potential for patent challenges from competitors claiming obviousness or prior art.
Patent Term & Remaining Patent Life
- Filing date: December 2021
- Expected expiration: December 2041, assuming 20 years from filing, with potential extensions for patent term adjustments based on examination timelines.
Freedom to Operate (FTO)
Analysis indicates FTO clearance for the specific molecule and claims is possible, given the uniqueness of the structure and recent filing date. Nonetheless, due diligence around similar kinase inhibitors and treatment methods is necessary.
Strategic Implications
- The patent’s breadth in composition and use claims supports both monotherapy and combination therapy development.
- The global patent family offers robust territorial protection but faces competition from existing kinase inhibitor patents.
- Continuous monitoring of related patent filings and potential oppositions is crucial.
Key Takeaways
- Patent 11,744,802 covers a novel kinase inhibitor with broad therapeutic claims in oncology.
- Its chemical composition claims are narrow enough to avoid prior art but broad enough to support multiple indications.
- The patent’s scope encompasses formulations, uses, and synthesis methods, offering comprehensive protection.
- The patent landscape shows active competition in kinase inhibitor space; patent validity may hinge on non-obviousness and novelty assessments.
- The patent lifecycle extends to 2041, providing long-term market exclusivity potential.
FAQs
1. What is the main therapeutic target of Patent 11,744,802?
It targets kinase pathways involved in tumor proliferation, mainly designed to treat solid tumors.
