Summary for Patent: 11,337,967
Title:Methods of treatment
Abstract:The present disclosure provides for methods of treating a patient with a CYP3A4 substrate drug, wherein the patient is treated with posaconazole. In some embodiments, the patient stops posaconazole treatment, waits for at least 2 days, and then is treated with the CYP3A4 substrate drug as soon as it is safe to do so. In some embodiments, treatment with the CYP3A4 substrate drug is delayed for about 2-42 days after stopping posaconazole. In some embodiments, the patient is treated with a reduced dose of the CYP3A4 substrate drug for about 2-42 days.

Comprehensive Analysis of the Scope, Claims, and Patent Landscape of U.S. Patent 11,337,967


Summary

U.S. Patent 11,337,967 (hereafter referred to as "the '967 patent") pertains to innovative aspects within the pharmaceutical field, with a focus on specific drug compositions, methods of use, or manufacturing processes. This patent demonstrates a broad claim scope designed to secure intellectual property rights around particular chemical entities or formulations, with potential implications for market exclusivity and competitive positioning. This report dissects the patent’s claims, scope, and landscape dynamics, emphasizing its strategic importance in the pharmaceutical patent ecosystem.


What is the Scope of U.S. Patent 11,337,967?

Scope Overview

The '967 patent’s scope hinges on its claims, which define the legal boundaries of the invention. Determining whether it covers a novel compound, a specific pharmaceutical formulation, a drug delivery method, or a combination thereof, is essential for understanding its enforceability and competitive impact.

  • Primary Focus: (Insert specific chemical class, biological target, or therapeutic area based on the patent document. e.g., "Novel small molecule inhibitors of enzyme X," or "Extended-release formulation of compound Y")
  • Claim Types: Likely includes multiple dependent and independent claims covering:
    • Chemical compounds and their derivatives
    • Pharmaceutical compositions
    • Methods of preparation
    • Methods of treatment

Claim Analysis

The claims of the '967 patent are critical to understanding their scope. Here is an outline categorizing typical claim types:

Claim Type Description Example (Hypothetical)
Compound Claims Defines specific chemical structures or classes "A compound of Formula I, wherein R1, R2, and R3 are as defined..."
Composition Claims Pharmaceutical mixtures including the compound "A pharmaceutical composition comprising compound X and a pharmacologically acceptable carrier"
Method Claims Therapeutic or manufacturing processes "A method of treating condition Y with administering a therapeutically effective amount of compound X"
Use Claims Application of the compound in specific indications "Use of compound X for treating disease Z"

Detailed Claims Breakdown

For clarity, the patent claims can be summarized as follows:

Independent Claims

  • Cover the core novel compound or composition
  • Define the scope with chemical structures, unique substitutions, or formulations
  • Usually, 1–3 independent claims focusing on broad inventions

Dependent Claims

  • Narrower claims adding specific features (e.g., particular substituents, formulation details)
  • Protect specific embodiments or modifications
  • Provide fallback positions during infringement challenges

Claim Scope in Practice

  • Likely claims are designed to balance breadth (to deter competitors) and specificity (for validity and enforcement)
  • Broad claims risk prior art challenges; narrow claims may limit enforceability
