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 supports batch prior-art comparison across multiple drafts

Starting 2026-07-29, AutoPatent includes a batch comparison mode that lets you load up to five draft claim sets against the same pinned reference collection. Each draft is scored independently for overlap with the reference set, and the results appear in a side-by-side comparison table. This is useful when you are evaluating multiple invention disclosures against a common prior-art portfolio and need to see which disclosure has the cleanest path. The batch mode preserves workspace context, so jurisdiction tags and notes travel with each comparison. This is an organizational improvement for parallel prior-art review; it does not constitute a legal opinion on novelty or freedom to operate. Contact: sapsap@qq.com.
