“Claim Drafter extracted the invention very well and drafted solid claims.“
Anna Klepacki, Patent Attorney
Experience the Difference
Don’t take my word for it. See the “Tool for Thought” in action before you commit.
1. Watch the Full Workflow
In this live demo video, I screen-share the entire process from the “blank page” moment to a finalized, pressure-tested claim set. See exactly how the AI acts as a critical thinking partner, not just a text generator.
2. Try the Free Preview
Now that you’ve seen the full picture, experience the first step yourself. I have released Step 1: Understanding the Invention as a public Custom GPT.
Paste a sample invention disclosure (or use this example) and see how it leads you from chaotic notes to a solid, structured understanding of the invention.
The Hidden Cost of “One-Click” Patent Drafting Robots
The adoption of AI in patent drafting has introduced a hidden professional risk: When patent attorneys rely on one-click draft generators, we risk becoming “intellectual tourists” in our own work; visiting ideas rather than inhabiting them, which eventually leads to shallow results.
Current research indicates that over-reliance on AI automation can lead to:
- Cognitive Laziness: A measurable reduction in critical thinking and logical discernment.
- The “Filled Page” Problem: Moving from the challenge of a blank page to the dangerous passivity of merely rubber-stamping robot-generated drafts as “good enough”.
- Skill Atrophy: Routine reliance on automated tools can degrade core analytical skills.
Powerclaim reverses this trend.
I didn’t build a “Writer”. I built a “Tool for Thought”: designed to provoke your critical thinking, protecting your professional agency while delivering significant gains in drafting speed.
Meet Your New Drafting Team
The Patent Drafting Toolbox consists of three specialized assistants that encode the wisdom of an expert European patent attorney into a high-performance workflow:
1. The Claim Drafter (The Architect)
Stop staring at a blank page. The Claim Drafter scaffolds critical thinking and analysis. It does not simply write claims; it prompts you to think through a structured framework that turns chaotic inventor notes into a solid, claimable structure before a single line is written.
2. The Claim Checker (The Adversary) COMING SOON
Most AI chatbots try to please you. This one tries to break you. Acting as a cynical patent examiner and a tireless workaround searcher, the Claim Checker aggressively pressure-tests your draft claims, identifying scope gaps, clarity issues, and enforcement risks before you file.
3. The Description Drafter (The Scribe) COMING SOON
Once your strategy is set, the Description Drafter handles the heavy lifting. It expands your claims into a full patent description, ensuring every feature is supported and every fallback position is fleshed out, grounded strictly in the source material you provided.
Your Practice, Your Rules: Deployment Models
Professional software should adapt to you, not the other way around. Choose the deployment model that fits your practice.
Option A: Cloud-Hosted
Best for: Attorneys who want immediate access.
How it works: Use the official assistants directly inside your existing ChatGPT or Google Gemini account.
Security: Zero setup. Your firm’s existing enterprise data agreements apply.
Option B: Self-Hosted
Best for: Privacy absolutists and “Builders”.
How it works: You get the source code (the raw prompts) and deploy it in your own environment.
Security: Absolute data sovereignty. Your client data never touches a third-party server you don’t control.

“I built this because I needed it for my own practice. Now, I’m sharing the logic with you.”
— Bastian Best, European Patent Attorney
AI software is only as good as the logic behind it. Powerclaim isn’t built by a generic dev team; it is my codified expertise. As a European Patent Attorney and an EPO-acclaimed “AI Patent Expert”, I spent years refining these prompts to meet the rigorous standards of our profession.
