Summary for Patent: 11,426,378

Title:	Method for long-term treatment of rosacea
Abstract:	A regimen for the long-term therapeutic treatment of rosacea. The regimen includes topically applying a pharmaceutical composition to the skin of a subject. The pharmaceutical composition includes about 1% w/w to about 10% w/w benzoyl peroxide as an active ingredient, and a pharmaceutically acceptable carrier or excipient. The benzoyl peroxide is the only active ingredient in the pharmaceutical composition, and the pharmaceutical composition is applied once daily for a period of about 52 weeks, to achieve, in a group of such subjects, a success rate of about 75%.

Detailed Analysis of U.S. Patent 11,426,378: Scope, Claims, and Patent Landscape

What does U.S. Patent 11,426,378 cover?

U.S. Patent 11,426,378, granted to [Assignee Name] on July 19, 2022, pertains to a novel composition and method related to [specific drug, class, or technology, e.g., a novel monoclonal antibody targeting PD-1]. It claims to improve [efficacy, stability, delivery, etc.] over previous formulations.

Scope of the Patent

The patent encompasses:

• A chemical composition or formulation with defined structural features,
• Methodologies for producing the composition,
• Specific therapeutic applications or methods of use,
• Variations and substitutions within predefined parameters.

The scope extends to:

• Use in treating [indications],
• Delivery via [specific routes, e.g., intravenous, subcutaneous],
• Compositions with [specific excipients, stabilizers, or carriers].

The claims are broad enough to cover [generic modifications] but specifically targeted at [targeted molecule or pathway].

What are the key claims?

Independent Claims

The independent claims focus on:

• A composition comprising [compound, e.g., a monoclonal antibody with specific modifications],
• A method of treatment involving administering the composition for [specific conditions],
• A method of production detailed through [specific steps or conditions].

Dependent Claims
