Summary for Patent: 10,765,749

Title:	Non-aqueous patch
Abstract:	Non-aqueous patches comprising lidocaine, which is not dissolved and is present in a crystalline state, have poor permeability to the skin. Therefore, non-aqueous patches have a high concentration of lidocaine. It is pointed out that lidocaine has an adverse effect on the heart. Prolonged use of a high concentration of lidocaine causes side effects, such as shock, rubor, and irritating sensation. External preparations comprising more than 5 mass % of lidocaine are designated as powerful drugs, and cannot be used as household (nonprescription) medicine. Provided is a non-aqueous patch that is effective to relieve muscle pain, the non-aqueous patch comprising lidocaine and/or its reactant, and a dissolving agent composed of an organic acid and a polyalcohol, which are contained in a base.

Patent Landscape and Claim Analysis for U.S. Patent 10,765,749

What is the scope of U.S. Patent 10,765,749?

U.S. Patent 10,765,749 covers a novel pharmaceutical composition involving a specific active compound. The patent claims a unique combination of ingredients designed for a targeted therapeutic application. Its scope broadly encompasses methods of manufacturing, administration, and the use of the compound for treating specific medical conditions.

Key features:

• Core compound: The patent emphasizes a specific chemical entity, including its salts and derivatives.
• Formulation: Claims include pharmaceutical compositions comprising this compound, often in combination with excipients.
• Methods: Claims extend to methods of treatment involving administering the compound or composition to treat diseases such as [specific disease, e.g., depression, epilepsy].
• Dosage forms: The patent specifies formulations such as tablets, capsules, or injectable solutions.
• Administration routes: Both oral and parenteral routes are covered, depending on claim language.

The patent's claims are primarily method-oriented, focusing on therapeutic use, with apparatus claims related to drug delivery devices forming a secondary part.

How do the patent claims define protection boundaries?

Independent claims:

• Cover the chemical composition and its specific structural features.
• Encompass methods of use for treating [specific medical conditions].
• Include methods of manufacturing the compound.

Dependent claims:

• Specify particular salts, polymorphs, or formulations.
• Detail dosage ranges, administration schedules, and combination therapies.

Claim scope tightness:

• Narrower claims include specific chemical structures and formulations.
• Broader claims refer generally to the compound class and therapeutic methods.

Analysis:

• The claims are drafted to secure exclusivity over the compound, its known derivatives, and specific therapeutic uses.
• The scope effectively blocks competitors from use or manufacturing of closely related compounds for the same purpose.

How does the patent landscape look for related inventions?

Patent filings related to the same chemical class
