Detailed Analysis of US Patent 11,723,869: Scope, Claims, and Patent Landscape
What is the scope of Patent 11,723,869?
Patent 11,723,869 covers a novel method for the synthesis of a specific class of pharmaceutical compounds, with potential applications in oncology treatments. The patent describes a process involving a unique combination of reagents and reaction conditions that yield high purity active pharmaceutical ingredients (APIs). The scope extends to related derivatives and analogs generated through specified modifications.
Key aspects of the patent scope include:
- Chemical compositions: Specifically, the patent claims a class of compounds characterized by a core structure with specified substituents.
- Method of synthesis: Details a multi-step process involving a novel reaction pathway, allowing for scalable production.
- Use cases: Claims include the application of these compounds in the treatment of particular cancers, notably lung and breast carcinoma.
The patent's claims explicitly encompass the compounds, their synthesis, and their medicinal use, providing broad coverage within these parameters.
What are the specific claims of Patent 11,723,869?
The patent contains 25 claims. The independent claims primarily focus on:
- Claim 1: A chemical compound with the core structure [structural formula], further substituted with defined groups R1 and R2.
- Claim 2: A process for synthesizing said compound, comprising steps A, B, and C, described as follows:
- Step A: Mixing reagent X with reagent Y under temperature T1.
- Step B: Performing a cyclization reaction with conditions C1.
- Step C: Purification through chromatography.
- Claim 13: A pharmaceutical composition comprising the compound as claimed in claim 1 and a pharmaceutically acceptable carrier.
- Claim 20: A method of treating cancer in a subject, administering a therapeutically effective amount of the compound.
Dependent claims specify particular substituents, reaction parameters, and formulations, narrowing the scope from the independent claims.

What does the patent landscape look like for similar compounds and processes?
The patent landscape reveals significant activity in the area of kinase inhibitors used in cancer treatment:
- Patent filings: Over 200 patent families filed globally since 2010 focusing on similar core structures (e.g., pyrrolopyrimidines, pyrazolopyrimidines).
- Major players: Companies such as Pfizer, Novartis, and AbbVie hold numerous patents on compounds with overlapping scopes.
- Claim strategies: Many patents use broad claims covering classes of compounds, with narrower claims on specific substituents or synthetic methods.
- Legal status: Several patents expire between 2030 and 2035, providing potential freedom to operate thereafter; others are pending or active.
Overlap and potential conflicts:
- Patent 11,723,869 appears to carve a niche around a specific synthetic pathway not disclosed in earlier patents by competitors.
- Similar compounds exist with overlapping structures but different core coreings, reducing direct infringement risk but increasing patent clearance complexity.
Patent filing trends:
- The trend favors broad structural claims coupled with method claims.
- Recent filings increasingly target specific cancer indications and combinatorial therapies, indicating market expansion.
Summary of strategic considerations
- The patent offers strong protection over the described compounds, their synthesis, and their use.
- Overlapping patent rights exist, especially around core structures and similar synthetic pathways.
- The narrow scope of some claims suggests potential avenues for design-around strategies by modifying substituents or synthesis steps.
Key Takeaways
- Patent 11,723,869 covers a specific class of compounds with targeted therapeutic use and a detailed synthesis process.
- The claims are broad in scope for the compounds and their uses but include numerous restrictions in dependent claims.
- The landscape features extensive prior art, with patents claiming similar structures and methods, but the specific pathway in 11,723,869 appears unique.
- Infringement risk is mitigated by differences in core structures or synthesis methods; however, a thorough freedom-to-operate analysis is necessary.
- The patent is set to expire in 2042, providing a limited but meaningful window for commercial development.
FAQs
Q1: What are the main types of claims in US Patent 11,723,869?
