Is AutoPatent free to use?

Yes. AutoPatent offers free patent search and optimization trials. A Pro plan is available for advanced features.

Which patent databases does AutoPatent search?

AutoPatent searches global patent databases including CNIPA (China), USPTO (USA), EPO (Europe), JPO (Japan), KIPO (Korea), WIPO, and more.

How does AI patent optimization work?

AutoPatent compares your invention description against existing patents in CNIPA, USPTO, EPO, and other databases. It then rewrites your description to emphasize novel technical features and differentiate from similar existing patents, with itemized explanations for each change.

Can AutoPatent guarantee my patent will be approved?

No tool can guarantee patent approval. AutoPatent helps you strengthen your application by identifying potential conflicts and suggesting improvements, but final approval depends on the patent office.

Is my patent idea kept confidential?

Yes. AutoPatent does not store your patent ideas permanently. All searches are processed in-memory and not shared with third parties.

How to Optimize Your Patent Description

The Optimize feature works in two modes: Pre-search polish — click Optimize before searching to have the AI refine your description for clarity, precision, and novelty. This is great for improving your initial draft. Post-search differentiation — after searching, click Optimize to have the AI rewrite your description to differentiate from the matched patents. This mode references specific patent numbers in its explanations. The dual-panel view shows your original text (top) and the optimized version (bottom). Changes are highlighted in yellow. Below the panels, you'll find a detailed breakdown explaining why each change was made. Both panels are editable — you can manually adjust the text further.
