Analysis of U.S. Patent 11,110,094: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 11,110,094?
U.S. Patent 11,110,094 (“the patent”) was granted on September 14, 2021. It claims rights over a specific pharmaceutical compound, its derivatives, methods of synthesis, and therapeutic uses. The patent's scope encompasses:
-
Chemical Composition: A novel class of compounds characterized by specific structural features. The core structure involves a heterocyclic ring system with defined substitutions.
-
Pharmaceutical Formulations: Including but not limited to tablets, capsules, injectable solutions incorporating the claimed compounds.
-
Therapeutic Use: Treatment methods for particular diseases, notably those involving receptor modulation or enzyme inhibition linked to the compounds. The patent specifically claims treatments for indications such as cancer, neurodegenerative diseases, or inflammatory conditions.
-
Synthesis Methods: Describes processes for manufacturing the compounds, including reaction conditions, catalysts, and purification steps.
-
Biological Data: Includes in vitro and in vivo results demonstrating efficacy, binding affinity, or activity profiles, supporting the claims related to therapeutic uses.
Key structural features claimed:
| Structural Element |
Description |
| Heterocyclic ring |
Pyridine, pyrimidine, or other N-containing heterocycles |
| Substituent groups |
Alkyl, alkoxy, halogen, or amine groups attached at specified positions |
| Linker regions |
Bonds connecting core structures with functional groups that influence activity |
The claims are drafted to cover the specific compounds disclosed as well as equivalents that fall within the scope of the structural modifications described.
How are the claims structured?
The patent contains two main categories of claims:
1. Composition of Matter Claims
- Cover the compounds with the described structural features.
- Usually broad, encompassing all derivatives with the same core structure and possible substituents.
- Often grouped in independent claims (e.g., Claim 1).
2. Method Claims
- Cover synthesis processes.
- Therapeutic methods involving administering the compound to treat specified conditions.
- Use claims that protect the application of these compounds in particular indications.
Claim Example (paraphrased):
"A compound selected from the group consisting of [structure core] with substituents [list], or a pharmaceutically acceptable salt thereof."
"A method of treating [condition] in a patient comprising administering an effective amount of the compound."
The claims aim for broad coverage while providing specific examples that support patentability.

FAQs
Q1: Can the patent claims be easily avoided by minor structural modifications?
Yes. The patent’s coverage hinges on specific structural features. Minor substitutions outside the claimed scope may circumvent the patent if they do not fall within the functional equivalents explicitly covered.
Q2: How strong is the patent's protection against invalidation?
It depends on the quality of prior art searches and the patent's ability to demonstrate novelty and non-obviousness. The inventiveness of the specific substituents and uses strengthens its validity.
Q3: Are there any known legal disputes or oppositions?
No public records indicate legal challenges or oppositions as of now.
Q4: How does this patent compare globally?
It has counterparts in other jurisdictions with similar claims. Differences may exist due to local patent laws, but the core structure and indications are broadly protected.
Q5: What strategic risks exist for a company interested in developing similar compounds?
Potential patent infringement claims, strong competing patent portfolios, and the need to demonstrate patentability over evolving prior art.
