About 50search

50search helps inventors explore prior art with free-account search and public search memos. Search is available in beta.

Search connects to USPTO, Google Patents, EPO Espacenet and Lens.org. Availability varies by source. Results are research aids, not an exhaustive search or a patentability opinion.

Drafting, forms and portfolio management are coming soon, in beta. They are not available for purchase. Checkout is blocked pending legal and insurance review; Stripe remains in test mode. Automated email reminders and a filing-ready package are not available.

Not a law firm. Not legal advice. We do not file applications or represent inventors. Consult a registered patent practitioner before filing. Future forms would be guides, not legal approval.
