The patent encompasses methods aimed at improving yield, purity, or process efficiency for certain active pharmaceutical ingredients (APIs). It primarily emphasizes chemical synthesis pathways, process parameters, and intermediate compounds.
Scope of the Patent
The scope of EP2072051 encompasses:
-
Process claims relating to the synthesis of pharmacologically active compounds, specifically methods involving certain chemical transformations, solvents, temperature conditions, and reaction sequences.
-
Product-by-process claims that define the API produced via the described synthesis route, where the process parameters are critical for the compound’s quality and efficacy.
-
Intermediate compound claims which cover specific chemical intermediates involved in the synthesis pathway, emphasizing their structural features and method of preparation.
The patent’s claims extend across various aspects of the manufacturing process, including catalyst use, specific reaction conditions, purification steps, and intermediate compounds.
Claims Analysis
The claims form the core of patent scope, and their robustness influences enforceability and licensing potential.
Independent Claims
-
The independent claims broadly cover the method of producing the target active pharmaceutical compound, focusing on a multistep chemical synthesis process.
-
Key features include the use of particular reagents, solvents, temperature ranges, and reaction times designed to optimize yield and purity.
-
The claims also specify certain intermediates characterized by particular chemical structures, often with Markush group formats to capture multiple variations.
Dependent Claims
-
These claims narrow the scope, providing specific embodiments, such as particular solvents or catalysts, or specific temperature ranges.
-
They often address process variations, safety measures, or purity specifications, offering a layered approach to patent protection.
Strength of Claims
-
