Esgenix

Esgenix is an AI-powered patent drafting platform that supports the preparation of patent applications from invention disclosure analysis through to export-ready documentation, designed for patent attorneys, patent agents, IP law firms, and in-house IP teams. The platform uses multiple large language models operating in parallel through an adversarial process to generate, debate, and review claim variants before producing drafts, with explainable audit trails accompanying all output.

Key Features & Functions:

Multi-LLM Claim Generation
The platform generates multiple independent claim variants simultaneously using an ensemble of large language models, each approaching the invention from a distinct drafting perspective. Users can compare, select, and merge elements across variants to produce a final claim set, with source-backed reasoning provided for each recommendation.

Scope Slider
A visual control allows users to broaden or narrow claim breadth in real time. The system rewrites claim language at each position and generates multiple coverage variations, with inline diff review enabling acceptance or rejection of specific wording changes before they take effect.

Prior Art Radar
Prior art references are surfaced and ranked by similarity during drafting, enabling attorneys to identify and assess relevant prior art before finalising claims.

Examiner's Lens
Automated compliance checks run against USPTO and EPO rules, covering antecedent basis validation, claim syntax, enablement, unity, clarity, and inventive-step weaknesses, as well as infringement analysis, novelty and inventiveness checks, and redundancy detection.

Zero-Prompt Application Builder
An invention disclosure uploaded to the platform generates a complete patent application package, including specification, claims, abstract, figures list, and drawing descriptions, without requiring the user to write prompts.

Counsel Personas
Multiple counsel-style personas are available, spanning conservative, prosecution-efficient, litigation-forward, and other drafting approaches, allowing users to apply different strategic orientations to claim generation and review.

Patent Drawings Generation
Publication-ready patent figures, including flowcharts, block diagrams, and system architectures, are generated automatically from claims and specification and exported as patent office-formatted files.

Adversarial Review
Multi-persona review agents simulate examiner objections and challenge claim novelty against cited prior art, covering patentability, infringement, and claim strategy assessments prior to filing.

Legal Expert Agent
An agentic assistant proposes concrete actions within the drafting workspace, including scope adjustments, analysis runs, and claim type changes, operating as an interactive co-drafter rather than a passive query tool.

Collaborative Review Workflow
Review can be assigned to a colleague within the platform. Both parties can leave inline comments on claim text, with a resolution function that collates comment threads and rewrites claims to address them, subject to diff review before acceptance.

Export and Audit Trail
Completed applications are exported as USPTO/EPO-formatted Word documents. Patent figures are exported as PowerPoint files formatted to patent office margin standards. A full redline audit trail documents all actions and revisions made during the drafting session.
