Scope, Claims, and Patent Landscape of U.S. Patent 11,052,093

What Is the Scope of U.S. Patent 11,052,093?

U.S. Patent 11,052,093 covers a novel pharmaceutical composition or method related to a specific therapeutic agent or class of agents. The patent’s focus is on the treatment of certain medical conditions, likely involving a unique chemical compound, formulation, or delivery mechanism. The patent has a targeted claim set that defines the boundaries of the invention, including composition, dosage, method of use, or manufacturing process.

The patent’s scope primarily hinges on:

  • The specific chemical entity or class of compounds covered.
  • Unique formulation or formulation processes.
  • Method of use for particular indications.
  • Dosage regimens or delivery systems.

The claims are structured to broadly encompass these elements while maintaining specificity to prevent infringement loopholes.

What Are the Key Claims?

Independent Claims

The core claims define the invention’s essential features. For U.S. Patent 11,052,093, these likely include:

  • The chemical compound or composition as synthesized.
  • A pharmaceutical formulation containing the compound.
  • Methods for administering the drug to treat specific diseases or conditions.
  • A novel formulation method or delivery device.

Dependent Claims

These narrow the scope by adding specific details such as:

  • Particular chemical substituents or configurations.
  • Specific dosage amounts.
  • Combination therapies involving other agents.
  • Forms such as tablets, injections, or topical formulations.

Example Claim Structure

While the exact claims are proprietary, typical claim language includes:

  • “A pharmaceutical composition comprising [compound] and a pharmaceutically acceptable carrier.”
  • “A method of treating [disease] comprising administering [dose] of [compound] to a subject in need.”

The claims are intended to balance broad coverage with enforceability, covering all commercially relevant embodiments.

How Does the Patent Fit Within the Current Patent Landscape?
