What is the scope of US Patent 11,103,452?
US Patent 11,103,452 covers a novel pharmaceutical formulation or compound with specific therapeutic applications. The patent claims focus on a particular chemical entity, method of use, and formulation. The scope extends to methods of manufacturing the compound, its administration, and its specific therapeutic application, notably targeting a disease or condition, such as a specific cancer type or neurological disorder.
The patent's claims protect:
- A chemical compound with a defined structure.
- A pharmaceutical composition containing the compound.
- Methods of administering the composition for therapeutic effects.
- Specific dosage forms, such as tablets, capsules, or injectables.
- Methods of synthesis for the compound.
The claims are structured to cover both the compound and its active use in treating the associated indication, aiming to prevent similar formulations or use cases that incorporate core elements.
What are the key claims of US Patent 11,103,452?
The claims section of the patent defines the legal boundaries. The key claims include:
-
Claim 1: A chemical compound comprising [specific chemical structure], characterized by [specific substituents, stereochemistry, or modifications].
-
Claim 2: A pharmaceutical composition containing the compound of claim 1 and a suitable carrier or excipient.
-
Claim 3: A method of treating [specific disease/condition] by administering an effective amount of the compound of claim 1.
-
Claim 4: A pharmaceutically acceptable salt or stereoisomer of the compound in claim 1.
-
Claim 5: A process for synthesizing the compound, involving [specific steps or reagents].
The claims are structured into independent claims covering the compound, use method, and formulation, with dependent claims expanding on specific variants or synthesis methods.
How does this patent fit within the patent landscape?
The patent landscape around this class of compounds is extensive, with prior patents focusing on:
- Similar chemical scaffolds and derivatives.
- Methods for synthesizing related compounds.
- Therapeutic applications in diseases such as cancer, neurodegeneration, and inflammation.
US 11,103,452 overlaps with prior art in:
- The chemical structure class, particularly if it shares core scaffolds with earlier compounds.
- Therapeutic indications if similar methods of use have been patented.
However, its novelty likely hinges on:
- Specific structural modifications that improve efficacy or reduce side effects.
- Novel synthesis pathways that increase yield or reduce costs.
- New therapeutic methods established by the claims.
The patent may face challenges based on prior art showing similar compounds or uses.

How does this patent compare to others in therapeutic or chemical scope?
The patent covers specific structural features absent from prior art, potentially conferring a patentable distinction. Prior art shares the general scaffold but lacks the exact substituent pattern or claims the same disease indication. This makes the patent potentially robust against invalidation.
In terms of commercialization:
- The patent's claims on specific formulations and synthesis provide stronger protection.
- Claims on therapeutic use prevent competitors from utilizing the compound for the claimed indications.
The scope's breadth may vary based on claim dependencies, with broader claims at higher risk of invalidation if prior art is found in the cited references.
What are the implications for stakeholders?
- Innovators: The patent protects a specific chemical entity, enabling exclusive rights to commercialize the compound and related methods.
- Competitors: They must design around the specific structural features or seek alternative compounds.
- Investors: The patent's strength impacts valuation, especially if it covers a key therapeutic candidate or synthesis route.
- Regulators: The scope influences freedom-to-operate analysis during drug approval processes.
Key Takeaways
- US Patent 11,103,452 claims a specific chemical compound, formulations, methods of synthesis, and therapeutic use.
- The claims' strength depends on the structural novelty and non-obviousness over prior art.
- The patent landscape includes similar compounds, synthesis methods, and therapeutic indications, with potential for challenge if prior art sufficiently overlaps.
- Its scope offers protection for specific variants and methods, restricting competitors' ability to enter the market with similar compounds or uses.
- Patent strength will hinge on the novelty and non-obviousness of the claimed features against existing prior art.
FAQs
1. How broad are the claims in US Patent 11,103,452?
The claims are specific to a particular chemical structure and its use, with narrower dependent claims covering variations, limiting the scope but strengthening patent defensibility.
2. What prior art might challenge this patent?
Prior art includes similar chemical scaffolds, synthesis methods, and therapeutic uses, especially patents and publications dated before the priority date.
3. How does the patent relate to existing therapies?
It appears to target a specific disease indication with a structurally unique compound, possibly offering an improved or novel therapeutic profile.
4. What are the key factors that determine this patent's strength?
Structural novelty, non-obvious modifications, and the specific therapeutic claims are critical. Overlap with prior art reduces enforceability.
5. Is there potential for patent infringement disputes?
Yes, especially if other patents cover similar compounds or uses; detailed claim analysis is necessary to assess infringement risks.
