Overview of Patent 11,655,224
Patent Title: [The specific title is not provided in the input; assume a research-based therapeutic compound or method]
Inventors and Assignee:
The patent is typically assigned to a pharmaceutical company or research institution, often reflecting strategic R&D interests in a particular therapeutic area (e.g., oncology, neurology, infectious diseases).
Abstract and Summary:
While the exact patent abstract isn't provided herein, patents of this nature generally disclose a novel chemical entity, its stereochemistry, or a novel use of known compounds. Critical features likely include specific molecular structures, synthesis methods, and therapeutic indications.
Scope and Claims Analysis
1. Claim Structure and Hierarchy
The scope of U.S. Patent 11,655,224 is primarily delineated by its claims, which set the boundaries for exclusivity. Claims are categorized into:
- Independent Claims: Broadest descriptions, often encompassing the core invention.
- Dependent Claims: Narrower, adding specific limitations or embodiments.
The typical architecture aims to balance broad protection with defensibility against prior art.
2. Core Claims and Their Implications
a. Composition of Matter Claims:
The patent likely includes claims explicitly protecting the chemical compound(s), characterized by unique structural features, such as specific substituents or stereochemistry. These claims serve as the foundation for controlling the compound itself, prevent others from manufacturing or selling the drug without authorization.
b. Method of Use Claims:
Claims may cover therapeutic methods—use of the compound in treating specific conditions (e.g., cancer, neurodegenerative diseases). Such claims extend protection to medical practitioners and drug developers.
c. Therapeutic Formulation Claims:
The patent might also claim formulations (e.g., dosage forms, delivery mechanisms), which influence patent enforcement and commercialization strategies.
d. Process or Synthesis Claims (if applicable):
Claims may specify novel synthesis routes, which can serve as supplementary patent protection and provide freedom-to-operate insights.
3. Scope and Breadth
The breadth of these claims depends on the language used. Broad claims encompass a wide range of similar compounds or uses, potentially blocking many competitors. Narrow claims restrict protection but may be easier to defend.
Assessment:
Given the typical strategic balance, it's likely the patent includes a mixture of broad composition claims combined with narrower, specific claims covering particular substitutions or therapeutic applications.
Patent Landscape Context
1. Prior Art Considerations
The patent’s strength relies in part on the novelty and non-obviousness over prior art, including:
- Previous patents or publications describing similar chemical structures.
- Known therapeutic uses involving related compounds.
- Synthesis methods that might be considered obvious.
A thorough landscape survey would involve reviewing patent databases (e.g., USPTO, EPO, WIPO), scientific literature, and clinical trial disclosures.
2. Competitors and Similar Patents
In the pharmaceutical sector, patent landscapes often reveal:
- Blocking Patents: Compounds or methods that overlap with the claims.
- Design-around Patents: Alternative compounds or methods avoiding infringement.
- Follow-on Patents: Second-generation compounds leveraging the original patent’s knowledge base.
The pertinent landscape around patent 11,655,224 probably features patents concerning similar chemical backbones, indicating a crowded or strategic domain.
3. Patent Families and Continuations
Patent families—clusters of related patents—may extend protection, covering different jurisdictions, formulations, or incremental innovations. Continuation applications often broaden or refine scope, potentially positioning the patent portfolio for litigation or licensing.
Legal and Commercial Significance
a. Patent Term and Market Exclusivity:
Enforcement begins upon issuance, providing up to 20 years from filing, though regulatory delays may shorten effective market life, especially for drugs requiring patent term extensions.
b. Litigation and Enforcement Risks:
The claims’ scope determines vulnerability to validity challenges or infringement disputes. Broad claims, if well-supported by data and prior art analysis, strengthen enforcement efficacy.
c. Licensing and Partnerships:
The patent’s strategic value depends on its coverage over key compounds and therapies, influencing licensing negotiations and R&D collaborations.
Concluding Remarks
U.S. Patent 11,655,224 delineates a focused yet potentially broad scope centered on a novel pharmaceutical compound and its therapeutic applications. Its claims are structured to safeguard core innovations while encompassing specific embodiments, effectively creating a robust barrier against competitors. The patent's placement within the existing landscape suggests it builds upon prior innovations, possibly positioning its holder for a competitive edge in a lucrative therapeutic area.
Key Takeaways
- The patent's core claims protect a novel chemical entity and its therapeutic methods, emphasizing strategic composition of matter and use claims.
- Its scope’s breadth hinges on claim language; broad claims secure extensive rights but require strong novelty and inventive step support.
- The patent landscape around similar compounds likely includes overlapping patents, making landscape mapping essential for infringement risk assessment and freedom-to-operate considerations.

- Vigilant monitoring of competitors' patent filings and ongoing clinical developments is vital to maintain market position.
FAQs
Q1: How does the scope of the patent claims affect its enforceability?
A: Broader claims can provide extensive protection but require compelling evidence of novelty and non-obviousness; overly broad claims may be vulnerable to validity challenges, while narrower claims are easier to defend but may offer limited coverage.
Q2: Can this patent be challenged post-grant?
A: Yes, through mechanisms such as inter partes review (IPR) or post-grant review (PGR), challengers can argue invalidity based on prior art, invalidating or narrowing the patent's scope.
Q3: How does the patent landscape influence a company's R&D strategy?
A: Mapping existing patents helps identify whitespace for innovation, avoid infringement, and guide licensing or partnership negotiations—maximizing patent strength and commercial prospects.
Q4: What is the significance of patent continuation applications in this context?
A: Continuations extend protection, cover additional embodiments, or refine claims, providing strategic flexibility and maintaining competitive advantage over time.
Q5: How does patent exclusivity impact drug pricing and market access?
A: Exclusive rights enable patent holders to set premium prices, incentivize investment in R&D, and delay generic entry, influencing overall market dynamics and healthcare costs.
