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.

AutoPatent now highlights jurisdiction-specific grace period deadlines

Starting 2026-07-31, AutoPatent displays a jurisdiction-specific grace period badge beside each pinned reference in the comparison sidebar. The badge shows the number of months between the disclosure date and the filing deadline for the reference jurisdiction. For example, US references show 12 months, EPO references show 0 months (no general grace period), and JPO references show 6 months. The badge is color-coded: green when the deadline is more than 3 months away, yellow when within 3 months, and red when expired or within 30 days. This is an organizational aid for reviewers; it does not constitute a legal opinion on grace period eligibility or filing strategy. Contact: sapsap@qq.com.
