Esgenix is an AI-native agentic patent workflow platform built for patent attorneys, IP law firms, and in-house intellectual property teams. Developed by patent practitioners, AI architects, and technologists with a combined 65 years of patent drafting experience, Esgenix streamlines the patent drafting process while maintaining explainability, legal rigor, and attorney control. The platform uses a council of multiple LLM agents that collaboratively brainstorm, debate, and generate prosecution-ready patent drafts with transparent redline audit trails and source-backed claim provenance. Rather than functioning as a simple AI drafting tool, Esgenix supports the complete patent workflow, from invention disclosure to filing-ready patent applications.
