Patent Analyzer

A free prompt system that turns your invention idea into a professional patent feasibility analysis

You have an invention. Before you spend $15,000–$30,000 on a patent attorney, you want to know: Can this actually be patented? Has someone already done it? What are the risks?

The Patent Analyzer is a set of AI prompts that walk you through a complete patent feasibility analysis — prior art search, statutory analysis, IP strategy, cost estimates, and a plain-English summary anyone can understand. No software to install. No API keys. Just copy, paste, and go.

Six Stages, One Copy-Paste Each

Each stage automatically produces everything the next stage needs. You just copy the handoff block and paste it into a new conversation.

Stage 1
Technical Intake
Restates your invention idea in precise, patent-ready technical language. Identifies components, inventive concepts, and classification. This is your starting point.
Stage 2
Prior Art Search
Executes live searches across Google Patents, USPTO, Google Scholar, ArXiv, GitHub, and commercial products. Finds what already exists and maps it against your invention.
Stage 3
Patentability Analysis
Full statutory analysis under §101 (eligibility), §102 (novelty), §103 (obviousness), and §112 (enablement). Identifies common examiner concerns in this technology area.
Stage 4
Deep Dive
Goes deeper into the specific technical domains that matter for your invention — AI, hardware, software, 3D printing, data pipelines, or whatever applies.
Stage 5
IP Strategy
Concrete filing recommendations: provisional vs. non-provisional, cost estimates, claim strategy, documentation checklist, and a filing landscape assessment.
Stage 6
Final Report
Assembles everything into a comprehensive 10-section report with risk scores, cost estimates, and a plain-English summary you can share with anyone.

Get Started in 3 Steps

  1. Open Stage 1 — Copy the prompt from Stage-1-Technical-Intake.md and paste it into a new Claude or Gemini conversation. Add your invention description after it.
  2. Copy the handoff — After the AI finishes, it produces a handoff block marked with a clear copy line. Copy it and paste into a new conversation.
  3. Repeat through Stage 6 — Each stage hands off to the next. After Stage 6, you have your complete patent analysis report.
No extra cost. With a Claude Pro ($20/mo), Claude Max, or Gemini Advanced ($20/mo) subscription, running these prompts is included. No API fees. No token charges. You're just using your chatbot.

Requirements

These prompts require an AI with live web search and a large context window.

Recommended: Claude Pro or Gemini Advanced Both offer 1 million+ token context windows and built-in web search. These prompts were developed and tested on Claude. Gemini Advanced is a strong alternative.
Not recommended: ChatGPT, Grok, Perplexity, or free-tier LLMs ChatGPT, Grok, and Perplexity have smaller context windows that will choke on the later stages. Free-tier LLMs lack web search — Stage 2 will now warn you if web search is unavailable and mark all references as unverified, but the analysis quality will be significantly reduced.

Who This Is For

Independent Inventors

You have an idea and want to know if it's worth pursuing a patent before spending thousands on an attorney.

Startup Founders

You need to understand your IP position before pitching investors or filing your first provisional.

Engineers & Researchers

You've built something novel and want a structured assessment of its patentability.

Small Businesses

You can't afford a $15K patent opinion on every idea. Screen them first, then invest in the winners.

Students & Academics

You want to learn how patent analysis works by running one on your own research or project.

Patent Attorneys

Use it as a first-pass screening tool for intake calls. Faster triage, better-prepared clients.

What the Report Covers

The final 10-section report includes everything you need to make an informed decision.

  1. Invention Summary — Your idea restated in precise technical language
  2. Inventive Concepts — The specific mechanisms that might be patentable
  3. Prior Art Landscape — What already exists, mapped against your invention
  4. Patentability Assessment — Full §101/§102/§103/§112 analysis with risk scores
  5. Deep Dive — Domain-specific analysis for your technology area
  6. IP Strategy — Recommended protection mix, filing strategy, claim directions
  7. Cost & Timeline — What to expect in dollars and years
  8. Risk Summary — Every risk scored 0–100 with mitigation strategies
  9. Overall Landscape Assessment — Landscape favors filing, significant obstacles identified, more documentation would strengthen position, or design patent avenue worth exploring
  10. Plain-English Summary — The whole thing explained like you're talking to a friend over coffee

What's New in v1.2.0

UPL compliance revisions — all prompts repositioned as research tools, not legal advice.

  1. Research assistant positioning — All 6 stages now position the AI as an “AI-powered research assistant” rather than a patent attorney or strategist.
  2. Mandatory disclaimers — Every stage output now begins with a disclaimer identifying the output as AI-generated research, not legal advice.
  3. Softened section titles — “File or Don’t File” is now “Filing Landscape Assessment.” “Bottom-Line Recommendation” is now “Overall Landscape Assessment.” Examiner rejection simulation is now “Common Examiner Concerns.”
  4. Updated assessment labels — “FILE NOW” is now “LANDSCAPE FAVORS FILING.” “DO NOT FILE” is now “SIGNIFICANT OBSTACLES IDENTIFIED.”
  5. Fact/judgment separation — Stage 3 now uses a Research Findings / Analysis Notes structure to separate factual observations from interpretive analysis.
  6. License change — License changed from MIT to CC BY-SA 4.0 with a UPL disclaimer retention clause requiring derivative works to preserve all legal disclaimers.

Prompt System vs. Desktop App

Two ways to run the same 6-stage analysis. Choose what fits your workflow.

Prompt System (this project)

  • Live web search for prior art
  • Works in any browser, any platform
  • No API key needed
  • Included with Claude Pro or Gemini Advanced
  • No software to install
  • Manual orchestration (6 copy-pastes)
  • Best prior art quality (web-grounded)

Desktop App (free)

  • One-click automated pipeline
  • Real-time streaming output
  • Auto-saves reports to disk
  • Encrypted API key storage
  • Requires Anthropic API key (~$1/run)
  • Prior art from training data (no web search)
  • Windows only
Which should I use? Use this prompt system if prior art accuracy matters most — live web search produces the best references. Use the desktop app if you want a one-click experience and don't mind that prior art comes from the model's training data rather than live search.
Legal Disclaimer
This prompt system provides strategic patent-analysis support, not legal advice. The analysis does not create an attorney-client relationship, does not constitute a formal patentability or freedom-to-operate opinion, and should not be relied upon as a substitute for engagement with a registered patent attorney. Always consult a registered patent attorney before filing.
