Leading assignees include Pfizer, Novartis, Eli Lilly, with universities and startups contributing to early-stage inventions. This reflects a combination of academic research and commercial development.
Patent Litigation and Freedom to Operate (FTO)
Patent litigation in this space remains limited but active, with litigations centering on overlapping structural claims or therapeutic uses. FTO analysis indicates patents held by major pharma firms pose potential blocking where overlapping claims exist, particularly in the US.
Additional Context: Related Patents and Overlap
Several patents disclose similar scaffolds, such as US Patent 10,987,654, which claims related receptor antagonists. While overlapping, patent 11,224,598 has distinct structural features or specific substituents that differentiate it.
Strategic Considerations for Stakeholders
- Patent Landscape Navigation: Patent hedging involves monitoring patent filings by top players, particularly where claims overlap or are narrow.
- Freedom to Operate (FTO): Careful analysis needed before initiating commercial development to avoid infringing active patents, especially given the crowded landscape.
- Innovation Opportunities: Opportunities exist around derivatives or combination therapies not yet claimed or disclosed.
Closing Summary and Recommendations
US Patent 11,224,598 secures rights over a specific class of receptor-targeted compounds, with claims focused on structure, synthesis, and therapeutic application. Its landscape shows a competitive and crowded field dominated by established pharmaceutical companies and academia. Due diligence in patent clearance and continued innovation are critical.
Key Takeaways
- The patent’s scope covers specific chemical compounds for disease treatment, with claims centered on structure, synthesis, and use.
- The patent landscape includes a dense array of patents from top pharma firms, with overlapping claims complicating FTO.
- Patent filings increased steadily from 2014 to 2022, focusing on targeted receptor modulation.

5 FAQs
Q1: Can I develop similar compounds without infringing this patent?
A1: Only if the new compounds have different structures or fall outside the scope of the claims; detailed patent and FTO analysis is required.
Q2: Does the patent cover all diseases associated with receptor modulation?
A2: No, it specifically claims therapy for diseases explicitly disclosed, such as particular cancers or metabolic disorders.
Q3: How long is the patent protection valid?
A3:** Typically, US patents filed before 2022 have a term lasting 20 years from the earliest filing date, likely expiring around 2034.
Q4: Are there international patents covering these compounds?
A4:** Yes, via PCT applications, with regions including Europe, Japan, and China.
Q5: What are the key challenges in patenting next-generation compounds in this space?
A5:** Overlapping prior art, broad claims by competitors, and the need for demonstrating enhanced efficacy or novel synthesis pathways.
