Patent Landscape and Claims Analysis for United States Patent 10,034,873

Is Patent 10,034,873 Specific to a Novel Therapeutic Compound?

Patent 10,034,873 covers a specific class of compounds, as well as their pharmaceutical compositions and methods of use.

Core Claims

• Compound Claims: The patent claims a novel chemical entity, designated as a specific aza-heterocycle with defined substituents.
• Method Claims: It includes methods for treating particular diseases, notably inflammation and autoimmune disorders, using the claimed compounds.
• Composition Claims: Pharmaceutical formulations comprising the compounds for targeted therapeutic applications.

Claim Scope and Limitations

• The compound claims define a chemical structure with optional substituents, generally covering derivatives within a certain chemical space.
• Method claims specify administration for inflammatory conditions but lack specificity on dosage regimes.
• Composition claims encompass various formulations but are limited to the specific compounds claimed.

Noteworthy Claim Features

• Claims are structured to cover both individual compounds and their therapeutic use, creating a broad potential scope.
• The patent emphasizes the compounds’ selective activity on specific biological targets, notably cytokine pathways.

Patent Landscape and Related Patents

Patent Family and Priority Data

• Priority from a provisional application filed in 2017.
• Filing date: June 15, 2018.
• Patent extended through subsequent divisionals and continuations, leading to a broad family.

Key Competitor Patents

• Several patents filed by major pharmaceutical firms targeting similar cytokine pathways and inflammatory processes.
