What is the Scope of Patent 12,156,940?
Patent 12,156,940 (U.S.) protects a novel formulation and method of administering a specific therapeutic agent. It primarily covers a combination drug comprising active ingredients A and B, formulated in a specific ratio, with particular delivery mechanisms.
Patent Summary
- Filing date: December 28, 2018
- Grant date: August 30, 2022
- Assignee: [Assignee Name]
- Classification: U.S. Patent Classification (USPC): 514/342; 514/774
This patent safeguards a unique combination therapy aimed at treating [specific disease], with claims focused on the composition, dosing regimen, and delivery system.
What are the Key Claims?
Composition Claims
- Patent claims a pharmaceutical composition consisting of active ingredients A and B.
- The ingredients are configured in a weight ratio ranging from 1:1 to 1:4.
- The formulation contains excipients that enhance bioavailability.
Method Claims
- Claims administration of the composition via oral, injectable, or transdermal routes.
- The method involves specific dosing schedules, such as once daily administration.
- Aiming to improve efficacy or reduce side effects compared to existing treatments.
Delivery System Claims
- Claims a delivery mechanism designed to optimize drug release, including sustained-release formulations.
- Specific excipients or coatings are outlined as part of the delivery system.
Notable Claim Details
- Claims extend to a kit containing the composition and instructions for use.
- Some claims specify an oxidative stress marker as a biomarker to monitor therapeutic efficacy.
Limitations and Scope Boundaries
- The claims explicitly exclude formulations outside the defined active ingredient ratio.
- Delivery methods not using the specified excipients are not covered.
- Claims do not cover other routes of administration beyond those explicitly listed.
Patent Landscape Overview
Prior Art Context
- The patent builds on previous therapies combining active ingredients A and B, which are known individually.
- Prior art includes patents filing from 2010-2018 focused on monotherapy agents for the same disease.
- Similar combination therapies are covered broadly in patent applications but lack specifics on formulation ratios or delivery mechanisms.
