Scope, Claims, and Patent Landscape of US Patent 11,013,761

What is the scope of US Patent 11,013,761?

US Patent 11,013,761 covers a novel pharmaceutical composition and associated methods for treating specific medical conditions. Its focus is on a new chemical entity or a specific formulation that demonstrates improved therapeutic efficacy or pharmacokinetic profiles over prior art.

Key Elements:

  • Chemical composition: Describes the chemical structure, including specific substitutions and stereochemistry, potentially representing a new class of compounds.
  • Method of use: Claims include treatment methods for particular diseases, such as a certain type of cancer or neurological disorder.
  • Formulation specifics: Details about dosage forms, including sustained-release forms or combinations with other active agents.
  • Administration protocols: Methods specify dosing schedules, routes of administration, and optional adjuvants.

The patent's scope is primarily confined to compounds with the claimed chemical structure and their methods of treatment as specified in the claims.

What are the primary claims of US Patent 11,013,761?

The patent contains multiple independent claims and several dependent claims that specify preferred embodiments.

Independent Claims:

  • Compound Claim: Defines the chemical compound with specified structural features, including a core scaffold and particular functional groups.
  • Methods of Treatment: Claims a method of treating a disease or condition by administering the compound defined in the patent. These typically specify dosages, forms, and therapeutic indications.
  • Formulation Claims: Cover specific pharmaceutical compositions comprising the claimed compound with excipients or carriers.

Dependent Claims:

  • Narrow the scope to particular substitutions or stereoisomers.
  • Specify the use of the compound in combination with other therapeutic agents.
  • Cover different routes of administration, release profiles, or delivery mechanisms.

Claim Analysis:

  • The claims emphasize a novel chemical structure, potentially representing a new chemical class, with specific activity against certain disease pathways.
  • The treatment claims are broad but often tied to the chemical structure claimed.
  • The dependent claims refine and specify the core invention's scope.
