IntelliPatent

IntelliPatent automates drafting of chemical patent claims by extracting structural scaffolds and Markush substituents from MDL SD files to define the scope of chemical composition inventions.

Key Features:

• Automated Claim Drafting: Processes input chemical analogs in MDL SD file format to identify general structural scaffolds and generate patent claim text focused on Markush structures with substituents.
• Claim Extension with Historical R-Groups: Augments claims by incorporating commonly observed R groups derived from historical data on the top 30 selling drugs in the United States to broaden coverage of chemical variations.
• Core and Variable Structure Identification: Distinguishes invariant core scaffolds from variable substructures, classifying them as initial scaffolds and R groups for accurate definition of claim scope.
• Export Format: Outputs generated claim text in Microsoft Word (.docx) format.

Scientific Applications:

• Pharmaceutical patent drafting: Converts datasets of chemical analogs into Markush-based claim language for small-molecule pharmaceutical inventions.
• Agrochemical and chemical composition IP: Supports preparation of patent claims for agrochemicals and other industries reliant on defined chemical compositions by enumerating scaffold and R-group variations.
• Claim coverage expansion: Enables broader coverage of potential chemical variants in patent claims by integrating historical R-group frequency data.

Methodology:

Processes MDL SD input to extract structural information, identifies general scaffolds and substituents to construct Markush structures, and applies a predefined set of rules together with historical R-group data (top 30 selling US drugs) to draft patent claims.
