Everything you need to know.
Yes, in most jurisdictions. The ESIGN Act and UETA in the US, and eIDAS in the EU, recognise e-signatures on IP assignment agreements as legally binding. Some jurisdictions require specific formalities for patent assignments (e.g., USPTO requires written assignment), which an e-signed document satisfies.
Some IP assignments benefit from notarisation, particularly for international recordal. Zignature integrates with remote online notarisation (RON) providers for jurisdictions where notarisation is required or recommended.
The USPTO accepts electronically signed IP assignment documents. After signing with Zignature, you can download the signed PDF and submit it through the USPTO Assignment Center (https://assignment.uspto.gov) for recordal.
Yes. Zignature's cross-border e-signature support covers most jurisdictions, and you can apply country-specific signing standards (Advanced Electronic Signature for EU contractors) for maximum enforceability.
IP assignments generally require some form of consideration (payment) to be enforceable. Zignature's templates include recitals for monetary consideration, equity, or other forms of value. Your legal counsel should advise on the appropriate consideration for each transaction.
Use Zignature's bulk send feature to dispatch IP assignment agreements to all new hires simultaneously. The template auto-fills each employee's name and role, and the completion dashboard tracks who has signed before their start date.
