Patent NZ736249: Scope, Claims, and Landscape Analysis

Last updated: March 22, 2026

What Is the Scope of Patent NZ736249?

Patent NZ736249 pertains to a pharmaceutical invention, focusing on a specific therapeutic agent or formulation. The scope encompasses the detailed description of the drug composition, manufacturing process, and intended use, including particular chemical entities or combinations.

The patent claims are centered on:

• The novel chemical compound or a specific pharmaceutically active formulation.
• Method of preparation or synthesis of the compound.
• Therapeutic use, particularly indicating the disease or condition targeted.
• Specific dosage forms, delivery methods, or formulations.

What Are the Key Claims of Patent NZ736249?

The patent includes multiple claims that define the maximum legal extent of the invention:

• Independent Claims:

  • Describe the core chemical molecule or composition.
  • Cover the method of preparing the active compound.
  • Encompass therapeutic applications, such as treating specific disease states.

• Dependent Claims:

  • Specify particular variants or derivatives of the compound.
  • Detail formulations like tablets, injectables, or topical applications.
  • Narrow down to specific dosages, delivery systems, or combinations.

The claims typically follow a hierarchical structure: broad independent claims followed by narrower dependent claims. A sample claim might stipulate a chemical compound with a particular structure, while dependent claims specify salt forms, crystalline forms, or specific dosing regimens.
