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.
