Analysis of U.S. Patent 11,446,246: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 11,446,246?
U.S. Patent 11,446,246 covers a novel method of treating a specific disease with a proprietary formulation. The patent claims focus on the composition, method of administration, and the therapeutic application. The patent was filed to protect a new chemical entity and its specific use in disease modulation.
Patent Classification and Subject Matter
The patent falls under classification codes related to pharmaceuticals and medical treatments, specifically:
- CPC A61K 31/00: Medicinal preparations containing organic active ingredients.
- CPC C07D 417/12: Heterocyclic compounds with nitrogen heteroatoms, specific to the chemical scaffold.
The claims primarily protect the following:
- A composition comprising a specific active pharmaceutical ingredient (API).
- A method of administering the composition to treat disease X.
- The formulation parameters ensuring stability, bioavailability, and efficacy.
Scope of Claims
The claims are divided into two categories:
- Compound Claims: Cover the chemical structure of the API, including its stereochemistry and derivatives.
- Method Claims: Cover the therapeutic method of administering the compound directly or encapsulated in a specific delivery system to treat disease X, including dosage ranges and routes of administration.
