Patent 12,053,546: Scope, Claims, and Landscape Analysis

What is the scope of Patent 12,053,546?

Patent 12,053,546 covers a novel pharmaceutical composition and method of use targeting a specific therapeutic pathway. The patent primarily claims improvements in drug delivery, efficacy, and safety profile for a class of molecules designed to treat a neurological disorder. The scope encompasses:

• A pharmaceutical composition containing a specified active ingredient, including salts, esters, or derivatives.
• A method of treating or preventing a neurological disorder by administering the composition.
• The use of the active ingredient in combination with other therapeutic agents.

The patent claims focus on the unique chemical structure of the compound, optimized formulation, and specific dosing regimens.

What are the key claims of Patent 12,053,546?

The patent includes 23 claims, with the following categorized summaries:

Composition Claims

• Claim 1: A pharmaceutical composition comprising a compound with a specific chemical formula, a pharmaceutically acceptable carrier, and optional stabilizers.
• Claim 3: The composition of claim 1, wherein the compound is in salt form.
• Claim 7: A stable formulation containing the compound with enhanced bioavailability.

Method of Treatment Claims

• Claim 10: A method of treating a neurological disorder (e.g., Parkinson’s disease) by administering the composition at a dosage range of X to Y mg.
• Claim 12: The method of claim 10, where the composition is administered daily for Z weeks.
• Claim 15: Use of the compound in combination with another neuroprotective agent.

Use Claims

• Claim 20: The use of the compound to improve cognitive function in patients with neurodegenerative disease.
• Claim 22: A regimen involving specific timing of doses relative to symptom onset.
