PatentRain Concept

Features

Built for patent-worthy thinking

Ten core capabilities that help you turn product ideas into clear, reviewable invention narratives.

Projects & canvases
Feature image
Organize inventions by project, keep multiple canvases per initiative, and jump between them quickly as ideas evolve.
Node-based ideation
Feature image
Capture concepts as nodes and connect them to express dependencies, data flow, and alternative embodiments clearly.
AI drafting assistance
Feature image
Use AI to draft, rewrite, and expand technical descriptions so your invention narrative becomes clearer and more complete.
Novelty prompts
Feature image
Guided prompts help you add constraints, variants, edge cases, and differentiators that make ideas less generic and more defensible.
AI Analytics
Feature image
Assess clarity gaps, differentiation opportunities, and completeness across your work so you know what to improve next.
Version history
Feature image
Track iterations and compare changes over time, making it easier to refine descriptions and roll back if needed.
Collaboration
Feature image
Invite teammates to co-develop inventions, share context, and keep everyone aligned across product and legal workflows.
Patent discovery example
Feature image
Browse gold-standard example canvases, preview a complete 12-node structure, then clone one into your project as a ready-to-edit scaffold.
Exports
Feature image
Generate shareable snapshots and briefs (e.g., PDFs) so you can circulate ideas and summaries outside the app.
Learning library
Feature image
Practical guidance on patents and describing inventions helps you structure content and avoid common pitfalls.

Frequently asked

FAQs

Answers to common questions about projects, canvases, and AI features.

1. What’s the difference between a Project and a Canvas?
A Project is the container for a product/initiative. A Canvas is where you build and connect invention ideas inside that project.
2. How should I structure a canvas?
Start with nodes for the problem, core solution, key components, data flow, and benefits. Add variants/alternatives and connect nodes to show how it works end-to-end.
3. What are nodes, and what should go in a node?
Nodes are the building blocks of your invention narrative. Include what it is, how it works, inputs/outputs, edge cases, and alternatives—written clearly enough that someone else can follow.
4. Why connect nodes?
Connections document relationships and dependencies (e.g., data/control flow). This improves clarity and makes it easier to turn your canvas into a patent-ready description later.
5. Can AI help me write node content?
Yes. AI can draft, rewrite, and expand technical descriptions, suggest missing elements, and propose variants. Treat it as a starting point and always review for accuracy and novelty.
6. What should I do when AI suggestions feel generic?
Add more specifics: constraints, system boundaries, concrete steps, thresholds, failure modes, and implementation options. The more grounded details you provide, the better the output.
7. What is AI Analytics used for?
AI Analytics helps you assess your work from multiple angles (clarity gaps, differentiation opportunities, completeness). Use it to iterate before sharing with counsel.
8. How does the Learning section help?
Learning provides practical guidance on patents and how to describe inventions. Use it to strengthen descriptions, avoid common pitfalls, and improve the structure of your canvases.
9. How do subscriptions and limits work?
Plans can control feature access (e.g., collaboration/AI usage) and may include daily AI limits depending on tier. When you hit limits, you can still view/edit your work, but AI features may pause until reset or upgrade.
10. How do I send feedback or report a problem?
Use the Feedback option in the app. Include what you were doing, what you expected, what happened instead, and which project/canvas you were in—this speeds up troubleshooting.
