Scope, Claims, and Patent Landscape for U.S. Patent 10,583,130

What is the scope of U.S. Patent 10,583,130?

U.S. Patent 10,583,130 (issued February 4, 2020) broadly claims a class of compounds, formulations, and methods for treating diseases associated with the N-acetyltransferase enzyme. The patent covers a novel selective inhibitor of N-acetyltransferase enzymes, specifically targeting therapeutic applications such as neurodegenerative diseases, cancers, and inflammatory conditions.

Key features:

• Chemical Composition: The patent discloses specific chemical structures characterized by a core structure with variable R-groups. These compounds inhibit N-acetyltransferase enzymes, which play roles in drug metabolism and disease pathways.
• Therapeutic Methods: It claims methods of administering the compounds to treat conditions like Alzheimer's disease, Parkinson's disease, certain cancers, and inflammatory diseases.
• Formulation Types: The patent includes formulations such as oral, injectable, and topical preparations.
• Novelty Elements: Emphasizes compounds with improved selectivity and reduced off-target effects compared to prior art.

Scope boundaries:

• Limited to compounds with specific structural formulas as indicated in the claims.
• Covers both the compounds and their man-made variants, including salts, esters, and prodrugs.
• Applies to methods of treatment that incorporate these compounds, with no claims extending to use in diagnostics or non-therapeutic applications.

What are the primary claims of Patent 10,583,130?

The patent has 20 claims, with the core claims focusing on compound structures and their use:

Core Claims:

• Claim 1: A chemical compound characterized by a specific core structure with defined substituents, capable of inhibiting N-acetyltransferase activity.
• Claim 2: Variants of Claim 1 that include salts, esters, or prodrugs.
• Claim 10: A method of treating a disease associated with N-acetyltransferase activity by administering an effective amount of a compound as claimed.
• Claim 15: A pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.

Dependent Claims:

• Specify particular substituents (e.g., halogens, methyl groups).
• Define dosage forms and routes of administration.
• Cover methods of synthesizing the compound.

Notable exclusions:

Claims do not extend to compounds outside the disclosed chemical scope or to methods unrelated to N-acetyltransferase inhibition.

Patent families and overlaps:

• The patent family includes applications in Europe, Japan, and China, with counterparts claiming similar compound classes.
• The scope overlaps with patents claiming enzyme inhibitors for other enzyme classes, but specific to N-acetyltransferase is a narrower subset.
• Competitors have filed for related compounds but differ in substituent patterns, target diseases, or method claims.

Litigation and licensing:

• No publicly documented litigation linked specifically to this patent.
• Licensing agreements are not publicly disclosed, but the patent's scope suggests strategic importance in neurodegenerative and oncology markets.

Trends and implications:

• The patent enters an active field with several filings from competitors focusing on enzyme inhibition.
• The focus on selectivity and reduced side effects aligns with current R&D priorities in precision medicine.
• The patent likely provides a competitive move to secure rights before clinical development progresses.

Key Takeaways

• U.S. Patent 10,583,130 covers specific chemical compounds designed to inhibit N-acetyltransferase enzymes, with therapeutic applications across neurodegeneration, cancer, and inflammation.
• The claims are primarily directed to compound structures, their salts/prodrugs, and methods of treatment.
• The patent landscape includes similar inhibitors claimed in filings worldwide; the scope is narrower in chemical structure but broad in therapeutic utility.
• Competitive activity in this area remains intense, emphasizing the importance of patent protection for novel, selective enzyme inhibitors.
• The patent's strategic value lies in controlling a niche but critical therapeutic target with ongoing clinical importance.
