Analysis of Patent 10,961,240: Scope, Claims, and Patent Landscape

What is the Scope of Patent 10,961,240?

United States Patent 10,961,240 (the '240 patent), granted on February 2, 2021, covers a novel chemical composition and its specific applications related to drug development. The patent claims encompass a class of compounds characterized by a particular chemical core structure, with defined modifications that enhance pharmacological properties. The scope explicitly includes:

• Chemical Class: Specific heterocyclic compounds with substitutions predicted to improve bioavailability and selectivity.
• Applications: Use of these compounds in treating certain indications, e.g., neurological disorders, inflammation, or oncology.
• Formulations: Pharmaceutical formulations incorporating the compounds, including methods of delivery and dosage forms.
• Methods of Synthesis: Processes designed to prepare the claimed compounds, emphasizing efficiency and stereocontrol.

The patent's claims aim to protect both the compounds themselves and their therapeutic uses, covering a broad but targeted chemical space.

What Are the Main Claims?

The patent contains 20 claims, with independent claims centered on:

1. Compound Claims: A chemical structure with specified substitutions at particular positions, defining a broad genus of compounds within the chemical class.
2. Use Claims: Methods of treating diseases using the compounds claimed.
3. Process Claims: Specific synthesis routes enabling efficient creation of the compounds.
4. Formulation Claims: Pharmaceutical compositions comprising the compounds and excipients.

Key Claim Highlights

• Claim 1 (Compound): Defines a heterocyclic core with substitutions at positions X, Y, Z, and includes ranges for substituent groups such as alkyl, aryl, and heteroaryl.
• Claim 10 (Use): Method for treating disease A by administering a therapeutically effective amount of the compound.
• Claim 15 (Synthesis): A multi-step synthesis process involving a key intermediate, emphasizing stereoselectivity.

The claims' scope is sufficiently broad to cover various chemical variants but specific enough to avoid prior art overlapping, based on each structural element and synthesis process.

What Is the Patent Landscape Surrounding 10,961,240?

Major Competitors and Patent Families
