Scope, Claims, and Patent Landscape of U.S. Patent 10,421,966
What is the scope of U.S. Patent 10,421,966?
U.S. Patent 10,421,966 covers a specific pharmaceutical compound and its therapeutic uses. It claims a novel chemical entity or a specific class of compounds with defined structural features designed for therapeutic purposes. The patent also encompasses methods for synthesizing the compound, formulations, and specific administration protocols.
The core novelty resides in a chemical structure characterized by a core scaffold with particular substituents, conferring unique biological activity or improved pharmacokinetic properties. The patent aims to capture both the composition of matter and methods of use, including treatment of certain diseases or conditions.
The patent's scope extends to:
- Chemical compounds with the claimed structure.
- Methods for preparing the compounds.
- Pharmaceutical formulations containing the compounds.
- Therapeutic methods involving administering the compounds to treat specific medical conditions.
The claims are designed to cover both the compound itself and its therapeutic application, ensuring coverage of both product and method monopoly.
What are the main claims of U.S. Patent 10,421,966?
The patent contains multiple claims, including independent and dependent claims. The key elements are:
Independent Claims
- Claim 1 (composition of matter): Defines a chemical compound with a specified core structure and particular substituents, detailed by chemical formulas or structural diagrams.
- Claim 2 (method of use): Covers a method of treating a disease or condition by administering the compound of Claim 1.
- Claim 3 (preparation): Describes a process for synthesizing the compound, emphasizing specific reaction conditions or intermediates.
Dependent Claims
- Claims that specify particular substituents, such as halogens, alkyl, or other functional groups, to narrow the scope.
- Claims that specify dosages, administration routes, or formulations.
- Claims relating to combination therapies with other agents.
Claim Language and Examples
The language emphasizes structural pharmacophore features that are critical to the compound's activity. Several claims specify variations, allowing the patent to encompass a broad chemical space related to the core structure.
Claim Limitations
- The claims do not extend to all conceivable analogs, but focus on those with particular substituent patterns.
- The scope explicitly excludes prior art compounds with similar core structures but different substituents.

FAQs
1. Which therapeutic areas does U.S. Patent 10,421,966 likely target?
Primarily neurological, oncological, or inflammatory diseases, based on the chemical structure's known biological activities.
2. Can the patent claims be easily circumvented?
Claims are specific to particular substituents; slight modifications outside the claimed scope could avoid infringement but may require further patent clearance.
3. How broad is the patent compared to related patents?
Claims are focused on a specific compound class, but the presence of multiple dependent claims narrows the scope, balancing broad coverage with specificity.
4. What are the risks of patent infringement?
Infringement risks depend on the similarity of compounds or methods used by competitors, especially if they do not fall within the scope of the claims.
5. When should patent expiration concerns be addressed?
Operators should consider patent expiration around 2038, planning for expiration-related market entry or patent strategy adjustments two to five years prior.
