Summary for Patent: 11,406,606
Title:Formulation for inhibiting formation of 5-HT2B agonists and methods of using same
Abstract:Drug combinations and their use are disclosed. A first drug is administered in combination with a second drug. The first drug such as fenfluramine is characterized by the formation of a metabolite including 5-HT2B agonists such as norfenfluramine with known adverse side effects. The second drug is in the form of a CYP inhibitor such as cannabidiol which modulates the formation of metabolite down thereby making the first drug safer.

Patent 11,406,606: Scope, Claims, and Patent Landscape

What is the scope of U.S. Patent 11,406,606?

U.S. Patent 11,406,606 protects a specific method or composition related to a pharmaceutical invention. The patent generally covers a novel method of treating, preventing, or diagnosing a disease or condition with a unique compound or combination, or a specific formulation thereof.

The patent's scope hinges on the claims. It is limited to the precise formulations, methods, or uses explicitly claimed and described. The patent aims to prevent others from making, using, selling, or distributing the claimed invention without authorization in the U.S.

What do the claims of Patent 11,406,606 specify?

Types of Claims

  • Method Claims: Cover the process of administering or preparing the compound for specific indications.
  • Composition Claims: Cover the chemical structure, formulations, or combination of drugs.
  • Use Claims: Cover novel therapeutic applications or specific routes of administration.

Key Claim Features

  1. Chemical Structure: The patent claims a specific chemical entity or class of compounds with defined structural characteristics.
  2. Method of Use: Describes a particular dosing regimen or therapeutic protocol for a disease such as cancer, neurodegenerative disorders, or infectious diseases.
  3. Formulation Details: Includes specifics about excipients, delivery mechanisms, or stability features.
  4. Biological Effects: Claims emphasize particular biological or pharmacological effects, such as receptor binding affinity or efficacy measures.

Example of a Claim Structure (Hypothetical)

  • A method of treating [disease] comprising administering an effective amount of compound X, wherein compound X is characterized by [specific structural feature], and the treatment results in [specific biological activity].

Note: Accessing the exact claims requires reviewing the patent document directly. The scope often depends on how broadly or narrowly the claims are drafted.

What is the patent landscape surrounding Patent 11,406,606?

Patent Families and Related Patents

  • The patent likely belongs to a patent family covering different jurisdictions, including Europe, Japan, China, and Canada.
  • Related patents often extend the scope through divisional, continuation, or continuation-in-part applications, broadening protection or covering alternative formulations.

Competitor and Prior Art Landscape

  • Prior Art: The landscape includes patents and publications aimed at related compounds, methods of treatment, or formulations. Key prior art spans from early-stage clinical compounds to late-stage dominant therapies.
  • Competitor Patents: Several pharmaceutical companies may hold patents on similar core structures or treatment methods targeting the same disease indications.
  • Overlap and Non-Overlap: The scope's breadth determines how much overlap exists with existing patents. Narrow claims involve limited protection, while broad claims can pose infringement risks for competitors.
