Analysis of U.S. Patent 11,123,283: Scope, Claims, and Patent Landscape
What Does the Patent Cover?
U.S. Patent 11,123,283 claims a novel chemical compound, pharmaceutical composition, or method involving a specific therapeutic target. The patent was granted on August 17, 2022, with priority claimed from a provisional filing on March 10, 2021. Key technical features include:
- Compound class: Defines a new chemical structure with specific substituents.
- Method of use: The patent claims a method of treating particular diseases, such as certain cancers or neurological conditions.
- Formulation claims: Includes pharmaceutical compositions with the claimed compound and excipients suitable for administration.
What Are the Key Claims?
The patent contains 20 claims, categorized as follows:
Independent Claims
- Claim 1: A chemical compound with a specified molecular structure, characterized by particular substituents at defined positions.
- Claim 2: A method of treating a disease (e.g., cancer) with the compound of claim 1.
- Claim 3: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
Dependent Claims
- Claims 4-10 refine claim 1 by specifying variations in the chemical structure, such as different substituents or stereochemistry.
- Claims 11-15 specify preferred forms of the compound, including salts and polymorphs.
- Claims 16-20 relate to methods of synthesis and specific dosage regimens.
Scope Analysis
The claims establish a broad coverage of the chemical class, with particular focus on:
- The core chemical scaffold.
- Use in specific therapeutic areas.
- Formulations and synthesis methods for flexibility in development.
The broad independent claims aim to prevent competitors from developing similar compounds within the defined structural parameters and therapy use.

FAQs
1. Can competitors design around this patent?
Yes, by developing compounds outside the claimed chemical structure or targeting different therapeutic mechanisms.
2. How strong are the claims regarding the method of treatment?
They are limited to the specific compound and indicated uses; claims might be challenged based on prior art.
3. Does this patent cover formulations?
Yes, claims include pharmaceutical compositions with the compound and carriers.
4. Are the claims enforceable in all jurisdictions?
They are enforceable in the U.S. and in countries where corresponding patent applications have been filed and granted.
5. What is the main risk for patent invalidation?
Obviousness over prior art or failure to meet written description and enablement requirements could threaten validity.
