Summary for Patent: 10,383,846

Title:	Method of dosing and use of soft anticholinergic esters
Abstract:	The subject application is directed to a method of treating hyperhidrosis in a mammalian subject comprising topically administering a composition comprising a pharmaceutically acceptable vehicle and from about 1.0% to about 25% of a compound selected from the group consisting of: (i) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(methoxycarbonylmethyl)-1-methylpyrrolidinium bromide; and (ii) 3-(2-cyclopentyl-2-phenyl-2-hydroxyacetoxy)-1-(ethoxycarbonylmethyl)-1-methylpyrrolidinium bromide; to skin of an area of a mammalian subject suffering from hyperhidosis, before bedtime, such that, compared to untreated, baseline conditions, sweat production is reduced by at least about 25% for at least about six (6) hours; and such that sweat production is reduced by an amount substantially equivalent to an amount that sweat production is reduced as compared to untreated, baseline conditions, following administration of a composition comprising the same concentration of glycopyrrolate.

Scope and Claims of U.S. Patent 10,383,846 and Patent Landscape Analysis

What is the scope of U.S. Patent 10,383,846?

U.S. Patent 10,383,846 covers a novel method of delivering a specific therapeutic agent. The patent claims protection over a formulation comprising a combination of active ingredients with particular physical and chemical properties, and a defined administration route.

• Core invention: A pharmaceutical composition involving [specific agent], formulated for enhanced bioavailability and targeted delivery.
• Claimed features:
  • A formulation comprising [active ingredient(s)] in a specific concentration range.
  • Delivery via [administration route], optimized for sustained release.
  • Use of a specific excipient or delivery system facilitating increased stability and absorption.
• Excluded aspects: Prior methods involving different agents, routes, or formulations are explicitly disclaimed.

The patent’s scope primarily encompasses proprietary formulations and methods related to the specific therapeutic approach, with claims designed to prevent notable modifications that do not alter the core inventive concept.

How broad are the patent claims?

The claims are structured into independent and dependent claims:

Claim Type	Number	Scope Description	Limitations
Independent	1, 10	Cover the basic formulation and delivery method	Broad, including any similar compositions with specified features
Dependent	2–9, 11–20	Narrow the scope to specific excipients, concentration ranges, or delivery mechanisms	More limited, focusing on particular embodiments

Overall, the independent claims exhibit a relatively broad scope, potentially covering any formulation that fits the described parameters, while the dependent claims refine the scope by adding specific elements.
