Feature Comparison

Eety AI - An AI Assistant for Patent Drafting

The 15-Point Invention Brain

Before drafting begins, Eety AI constructs a deep, structured model of your invention across 15 critical dimensions, from the core inventive concept to component interactions and novelty assessment. This isn't simple keyword matching; it's genuine technical comprehension. Each dimension is confidence-scored, and incomplete fields proactively block the drafting process, ensuring no strategic gap goes unnoticed. The system then asks highly targeted, technical questions to fill these gaps precisely, updating its understanding surgically without disturbing confirmed analysis.

Attorney-Led 10-Phase Drafting Pipeline

Eety executes drafting through a deliberate, 10-phase pipeline that requires attorney approval at each major step. An attorney-approved plan is established before any section is written, guaranteeing the final application aligns with your strategic intent from the outset. This controlled process ensures you maintain complete oversight, with the AI acting as a meticulous executor of your instructions rather than an autonomous agent making its own strategic decisions.

Style DNA & Multi-Jurisdictional Templates

Your patents should sound like your patents. Eety AI's Style Intelligence reverse-engineers your unique writing voice—including your hedging patterns, formality, and phrasing—from reference filings you provide. This ensures the generated prose is unmistakably yours, not generic AI text. Furthermore, it offers nine specialized templates that enforce the precise drafting conventions of major patent offices including the USPTO, EPO, PCT, and UKIPO.

Editable SVG Drawings & Integrated Workflow

The tool automatically generates professional, editable SVG drawings with numerals consistently tracked across all figures and the corresponding descriptive text. This integration eliminates manual cross-referencing errors. The platform completes the professional workflow with features for team access, a full audit trail, style compliance checking, and section-level review, providing a comprehensive, collaborative environment for preparing bulletproof applications.

Ensuring Consistency and Quality in Law Firm Workflows

Mid to large-sized law firms can integrate Eety AI to standardize drafting quality and style across multiple associates and teams.

Its methodical process of building an invention model and its practice of asking precise, technical questions to fill knowledge gaps provide a transparent masterclass in patent strategy and thorough disclosure analysis.

Corporate IP teams facing a high volume of internal invention disclosures can use Eety AI to efficiently triage and begin the drafting process.

Overview

About Eety AI - An AI Assistant for Patent Drafting

Eety AI is a sophisticated AI assistant designed specifically for patent professionals, acting as the brilliant junior associate you wish you'd hired years ago. It doesn't aim to replace the attorney but to amplify their expertise by handling the heavy lifting of patent drafting with precision and deference. The core philosophy is that patent drafting is a strategic problem first; one wrong assumption can undermine an entire application. To solve this, Eety builds a comprehensive 15-point invention model—called "The Brain"—before writing a single word. This model captures novelty, component interactions, and claim strategy, confidence-scoring each dimension and blocking progress until critical gaps are resolved through targeted, engineer-perspective questions. Drafting then proceeds through a meticulous 10-phase pipeline, generating attorney-approved plans, editable SVG drawings, and text that mirrors the attorney's unique writing style. Built for serious practice, it supports key patent office conventions and includes team collaboration tools, ensuring a robust, secure, and controlled pre-filing workflow.

Frequently Asked Questions

Eety AI - An AI Assistant for Patent Drafting FAQ

How does Eety AI differ from generic AI writing tools?

Eety AI is built from the ground up for the specific, high-stakes domain of patent law. Unlike generic tools that simply fill templates, Eety focuses on strategic comprehension first, building a detailed "Brain" model of the invention to identify novelty and gaps before writing. It defers to attorney strategy, asks questions instead of making assumptions, and clones your unique writing style, functioning as a specialized colleague rather than a generic text generator.

What kind of input documents does Eety accept?

The platform is designed for flexibility, accepting a wide range of input formats to build its invention model. You can upload invention disclosures, technical specifications, research papers, and even rough inventor notes in common formats including PDF, DOCX, TXT, and images. The system parses each document individually to extract structured knowledge.

Can I maintain control over the drafting strategy and final output?

Absolutely. Control and attorney oversight are core tenets of Eety's philosophy. The AI does not decide claim scope or prosecution angles. You set the strategy, and Eety executes. The 10-phase pipeline requires your approval before major steps, and you can direct revisions at any point. It is designed to amplify your expertise, not replace your judgment.

Does Eety support international patent applications?

Yes, Eety AI is built for a global practice. It includes nine specialized drafting templates that enforce the formal conventions and specific requirements of major patent jurisdictions, including the United States (USPTO), Europe (EPO), international applications under the Patent Cooperation Treaty (PCT), and the United Kingdom (UKIPO).

Pure Tax Investigations FAQ

What is the difference between a compliance check and a tax investigation?

A compliance check is a routine review by HMRC to check the accuracy of a tax return. It is often limited in scope. A tax investigation, such as under COP8 or COP9, is far more serious and intrusive, launched when HMRC suspects significant errors, avoidance, or deliberate fraud, and can delve deeply into personal and business affairs.

When should I seek specialist help for a tax investigation?

You should seek specialist help immediately upon receiving any formal communication from HMRC indicating an enquiry or investigation. Early intervention is crucial. Specialists like Pure Tax Investigations can manage all contact, ensure you respond correctly, and prevent missteps that could escalate the situation or increase potential penalties.

What is Code of Practice 9 (COP9) and how can you help?

COP9 is an HMRC procedure used when they suspect deliberate tax fraud but are offering a chance to make a full disclosure under the Contractual Disclosure Facility (CDF) to avoid criminal prosecution. Our help is vital to navigate this high-stakes process, prepare a technically robust disclosure, and negotiate the civil monetary settlement.

Can you help with disclosures for cryptocurrency gains?

Yes. Pure Tax Investigations has specific expertise in crypto tax disclosures and enquiries. They can calculate historic gains and income from cryptocurrency transactions, advise on the correct tax treatment, and manage the disclosure process to HMRC, whether as a voluntary disclosure or in response to an enquiry.
