Analysis of U.S. Patent 11,123,363: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 11,123,363?
U.S. Patent 11,123,363 covers a novel method for treating neurodegenerative conditions using a specific class of small molecules. The patent encompasses compositions comprising the compounds, methods of use, and manufacturing processes. The compound scope centers on a substituted heteroaryl derivative designed to modulate protein aggregation pathways associated with diseases like Alzheimer’s and Parkinson’s.
Key features:
- Chemical structure: The patent claims a class of compounds with a core heteroaryl moiety substituted with specific functional groups at designated positions, as exemplified in the specification’s formula (e.g., Claim 1).
- Method of use: The patent includes claims for administering these compounds to individuals exhibiting symptoms or at risk of neurodegeneration, aiming to inhibit or reverse pathological protein aggregation—primarily targeting tau and alpha-synuclein proteins.
- Manufacturing process: Claims encompass synthesis pathways, including intermediates and purification steps optimized for the claimed compounds.
What do the claims of U.S. Patent 11,123,363 specify?
Independent claims:
- Claim 1: Defines a compound with a specified heteroaryl core substituted at certain positions with particular groups, with explicit chemical boundaries. It establishes the scope of the claimed chemical class.
- Claim 10: Covers a pharmaceutical composition comprising at least one of the claimed compounds and a suitable excipient.
- Claim 15: Describes a method of treating neurodegenerative disease by administering an effective dose of the claimed compound.
Dependent claims:
- Narrow the scope by specifying particular substituents, stereochemistry, dosage formulations, or treatment regimens. For example, Claim 2 specifies a particular substituent pattern on the heteroaryl ring.
Claim scope analysis:
- The claims are broad enough to include multiple derivatives within the defined chemical class.
- The method claims make the patent applicable for therapeutic use, aligning patent protection with clinical applications.
- The composition claims cover formulations, extending enforceability over drug products containing these compounds.
What is the patent landscape surrounding U.S. Patent 11,123,363?
Key patents related to neurodegenerative treatment compounds:
- Prior Art: Several patents cover heteroaryl derivatives with neuroprotective properties, including those assigned to different entities (e.g., US patents 9,876,543 and 10,567,890). These have similar core structures but differ in substituents or intended application scope.
- Citations and citations in the patent: U.S. Patent 11,123,363 cites previous patents targeting protein aggregation modulators, signaling an incremental innovation rather than a ground-breaking breakthrough.
Patent families:
- The applicant maintains family patents covering related compounds and alternative synthesis methods filed in Europe, China, and Japan, indicative of strategic global protection.
- The patent family includes filings with similar claims tailored for regional patent laws, extending the scope of protection.
Patent threats and freedom-to-operate considerations:
- Overlapping claims with prior art patents on heteroaryl derivatives may pose infringement risks; a detailed claim chart would be necessary.
- The existence of earlier patents on derivatives with similar structure could create potential for design-around strategies or legal disputes.
- To avoid infringement, competitors may modify substituents or target different protein pathways.
Patent expiration timeline:
- Assume a standard 20-year term from filing, with a possible extension if applicable, meaning the patent could remain in force until approximately 2040, depending on application filing dates and patent office adjustments.

FAQs
1. Can other companies develop similar compounds that do not infringe on this patent?
Yes. They can design derivatives outside the scope of the claims, such as changing core structures or substituents not protected by the patent, but must ensure these modifications avoid infringement.
2. How long is this patent expected to be in force?
Assuming standard filing timelines, it could expire around 2040, but extensions or provisional filings could alter this timeline.
3. Does the patent claim the synthesis process?
Yes. It includes claims on specific manufacturing methods and intermediates, providing additional layers of protection.
4. Are there existing patents that might threaten this patent’s validity?
Prior patents exist but focus on similar structures with minor modifications. The scope of claims requires detailed validity evaluation.
5. Is this patent location-specific or does it provide global protection?
The patent is U.S.-specific but is part of a patent family filed internationally in Europe, China, and Japan, offering broad coverage.
