Feature Comparison

Eety AI - An AI Assistant for Patent Drafting

The Invention Brain

Before a single word of the patent is written, Eety AI constructs a detailed 15-point mental model of your invention. This "Brain" goes beyond keyword scanning to genuinely comprehend the inventive concept, novelty, and interactions between all components. Each dimension is confidence-scored, and incomplete fields actively block the drafting process. This ensures the foundational strategy is solid, preventing critical oversights that could jeopardize the patent's defensibility later.

Strategic, Attorney-Led Drafting Pipeline

Drafting is not a single step but a controlled, 10-phase pipeline. Eety AI does not proceed autonomously. It creates an attorney-approved plan for each phase before execution begins. You review and direct the strategy at every critical juncture—from claim scope to prosecution angles. This guarantees the final application reflects your expert judgment and intent, not an AI's best guess, making the process predictable and secure.

Your Voice, Captured and Applied

Your patents should sound like you wrote them. Eety AI's Style DNA technology analyzes your previous reference filings to reverse-engineer your unique writing voice, including your formality, hedging patterns, and phrasing. It then applies this learned style to all generated text, ensuring the output is indistinguishable from your own work. This maintains your professional signature and avoids the generic, unmistakably AI-generated prose of other tools.

Complete Pre-Filing Workflow System

Eety AI is a full workflow platform, not just a drafting widget. It supports team collaboration with controlled access and maintains a complete audit trail of all changes and decisions. The system includes style compliance checking, section-level review capabilities, and generates professional, editable SVG drawings with numerals tracked consistently across all figures and text. It also offers nine templates tailored to USPTO, EPO, PCT, and UKIPO conventions.

Pure Tax Investigations

Specialist Intermediary Role

Pure Tax Investigations positions itself as a dedicated buffer between the client and HMRC. This means the experienced team handles all direct communication, negotiation, and correspondence with the tax authority. This foundational feature ensures the client's interests are professionally represented, reducing personal stress and preventing missteps that could escalate the situation during sensitive investigations or disclosure processes.

Expertise in Serious Civil Investigations

The service has deep, specialised knowledge in handling the most severe HMRC civil enquiries, namely Code of Practice 9 (COP9) and Code of Practice 8 (COP8). COP9 cases involve suspected tax fraud, while COP8 tackles complex avoidance arrangements. The team's expertise includes understanding the procedural nuances, managing the Contractual Disclosure Facility (CDF), and formulating strategic responses to these in-depth and intrusive investigations to secure the best possible outcome.

Comprehensive Tax Disclosure Management

Pure Tax Investigations guides clients through various voluntary disclosure facilities to regularise their tax affairs before HMRC launches an investigation. This includes managing disclosures under the Worldwide Disclosure Facility (WDF) for offshore matters, the Let Property Campaign (LPC) for rental income, and specific disclosures for crypto assets or Indian investment income. This proactive feature helps clients correct past errors under favourable terms.

Bespoke, Client-Centric Advice

The approach is not generic. The team begins by listening to understand the unique complexities of each client's financial and business situation. Advice is then tailored pragmatically, focusing on clear, actionable steps. This foundational principle ensures solutions are commercially sensible and aligned with the client's personal and business aspirations, rather than offering a one-size-fits-all template.

Use Cases

Eety AI - An AI Assistant for Patent Drafting

Accelerating First Draft Creation for Solo Practitioners

For attorneys managing their own practice, time is the most limited resource. Eety AI acts as a force multiplier, handling the heavy lifting of transforming rough invention disclosures, technical specs, or even inventor notes into a structured, strategically sound first draft. This allows the practitioner to focus their valuable time on high-level strategy, client consultation, and refining the application rather than on initial drafting and formatting from scratch.

Ensuring Consistency and Quality in Large IP Departments

In-house legal teams and large law firms can use Eety AI to standardize drafting quality and strategic approach across multiple associates and cases. By using the Brain to establish a consistent foundation for every invention and applying learned style DNA from senior attorneys, the tool helps maintain a high, uniform standard. It reduces variability and ensures that even junior team members produce work that aligns with the firm's best practices and strategic goals.

Managing Complex Inventions with Interdependent Components

For highly technical inventions in fields like software, biotechnology, or advanced mechanics, mapping all component interactions is critical. Eety AI's 15-point Brain is specifically designed to parse and model these complex relationships. It asks targeted, engineer-perspective questions to fill comprehension gaps, ensuring the draft accurately captures how the system works as a whole, which is essential for crafting strong, defensible claims.

Streamlining International Patent Filings

Preparing applications for multiple jurisdictions is a tedious process of adapting to different format and convention rules. Eety AI simplifies this with its suite of nine templates built for major patent offices like the USPTO, EPO, PCT, and UKIPO. Attorneys can generate a core draft and then efficiently adapt it for international filing, saving significant time on reformatting and reducing the risk of procedural errors.

Pure Tax Investigations

A business owner receives a letter from HMRC opening an investigation under COP9, indicating suspicion of tax fraud. This is a critical situation with potential for serious penalties. Pure Tax Investigations steps in to manage the process, advise on the contractual disclosure facility, liaise with HMRC, and prepare a robust disclosure report to settle the matter civilly and avoid criminal prosecution.

Making a Voluntary Disclosure via the Worldwide Disclosure Facility (WDF)

An individual with previously undisclosed income from offshore investments or bank accounts wishes to become tax compliant. Pure Tax Investigations assists in preparing and submitting a full disclosure under the WDF, calculating the tax, interest, and penalties due, and managing the process with HMRC to secure a finalised agreement and achieve closure.

Responding to an HMRC Compliance Check

A company receives a notice that HMRC is conducting a compliance check into its recent Corporation Tax return. While perhaps routine, it can be burdensome. Pure Tax Investigations handles the enquiry, gathers and presents the required information professionally, and ensures the company's position is defended correctly to prevent the check from escalating into a wider investigation.

Defending Against an Inheritance Tax Enquiry

The executors of an estate face an HMRC enquiry into the valuation of assets or the application of reliefs for Inheritance Tax purposes. Pure Tax Investigations provides specialist support, analysing the technical aspects of domicile, trust structures, or property valuations to defend the estate's position and negotiate a fair settlement with HMRC.

Overview

About Eety AI - An AI Assistant for Patent Drafting

Eety AI is a fundamental rethinking of how artificial intelligence should assist in the complex, high-stakes field of patent law. It is not a generic text generator. Instead, it is a strategic drafting partner built from the ground up to think like a patent professional. The core philosophy is simple: patent drafting is a strategy problem before it is a writing problem. One wrong assumption or gap in the novelty argument can undermine an entire application. Eety AI addresses this by first building a deep, structured understanding of the invention itself. It creates a "Brain"—a comprehensive 15-point model of the invention that captures novelty, component interactions, and claim strategy. This model must be complete and confidence-scored before any drafting begins, ensuring strategic soundness from the start. Eety AI is designed for patent attorneys, agents, and in-house counsel who seek to amplify their expertise, not replace it. It acts as a brilliant, always-available junior associate that defers to your strategic direction, asks precise questions instead of making assumptions, and drafts in your unique professional voice. The tool manages the entire pre-filing workflow from document ingestion and iterative analysis through a 10-phase drafting pipeline, generating attorney-approved plans, editable drawings, and compliant drafts for major patent offices.

Frequently Asked Questions

Eety AI - An AI Assistant for Patent Drafting FAQ

How does Eety AI differ from other AI writing tools?

Eety AI is fundamentally different because it is built for strategy first, not just text generation. Other tools may fill templates based on keywords, but Eety starts by building a comprehensive "Brain" model of your invention to ensure strategic soundness. It defers to your expertise at every step, asks questions instead of making assumptions, and writes in your unique voice. It is designed as a collaborative associate, not an autonomous agent that operates outside your control.

What kind of input documents does Eety AI accept?

The system is built for flexibility. You can upload invention disclosures, technical specifications, research papers, and even rough inventor notes in common formats including PDF, DOCX, and plain text files. Eety AI parses each document individually, extracting structured knowledge from this unstructured input to begin building its deep understanding of the invention, typically in about 30 seconds per document.

Can I control the drafting process and make revisions?

Absolutely. Control is a core principle of Eety AI. The tool operates through a clear 10-phase pipeline and requires your approval at strategic checkpoints before proceeding. You can direct it to cast a wider or narrower claim net, rewrite sections entirely, or tighten specific language. Every revision starts with your explicit direction; the AI does not decide major changes on its own, ensuring the final product is exactly what you intend.

Is my confidential invention data secure?

Security is a foundational part of Eety AI's design, described as "Secure by DNA." The platform is built with enterprise-grade security protocols to protect sensitive client information and invention details. It includes features for controlled team access and maintains a complete audit trail. You retain full ownership and control over all the intellectual property and data you input into the system.

Pure Tax Investigations FAQ

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

A compliance check is typically a review by HMRC to confirm the information on a tax return is correct and complete. It is often routine. A tax investigation is more serious and invasive, usually triggered by suspicion of error, omission, or deliberate wrongdoing. Investigations like COP8 or COP9 are formal, in-depth processes examining records and transactions across multiple years.

When should I seek specialist help for a tax investigation?

You should seek specialist help immediately upon receiving any formal communication from HMRC that indicates an enquiry, check, or investigation. Early intervention is crucial. A specialist can ensure you respond appropriately from the start, protect your rights, and prevent the situation from worsening. Do not wait until the investigation becomes more complex.

What does the process involve under Code of Practice 9 (COP9)?

Under COP9, HMRC suspects tax fraud but offers a chance to settle civilly. The process involves accepting HMRC's terms to make a full disclosure under the Contractual Disclosure Facility (CDF). You must then prepare a detailed report admitting all irregularities, calculating what is owed. A specialist guides this entire process, negotiates with HMRC, and aims to avoid criminal proceedings.

Can you help if I have already started dealing with HMRC myself?

Yes. It is very common for individuals or businesses to contact Pure Tax Investigations after initially attempting to handle an HMRC enquiry themselves. The team can take over immediately, review what has been submitted, correct any missteps, and establish a proper defence strategy. It is never too late to get expert representation.
