Securing patent or trademark apostilles can take six to nine months due to the role of various government offices.
If you wait until you absolutely must have an apostilled patent or trademark, it is already too late.
An apostille is a certificate issued by a competent authority in the country where a public document originates; it confirms the authenticity of the signature, seal, and capacity of the official who executed the document.
Apostilles are specifically designed to replace traditional consular/legalization chains among Hague member states. For U.S. federal documents such as patents and trademarks, apostilles are issued by the U.S. Department of State, which render those documents valid for use in other Hague-member countries.
In the patent context, this means that documents such as patent application oaths, assignments, or certified copies of patents can be authenticated once via apostille rather than requiring separate consular legalization for each destination country that is a party to the Hague Convention.
Common intellectual property documents requiring apostilles:
Without proper authentication, foreign authorities can reject documents as invalid or insufficiently proven, causing delay and potentially jeopardizing your rights. Presenting apostilled patents and trademarks reduces the risk that a foreign patent office, court, or licensing counterpart or assignee will question the authenticity of signatures or seals.

David Wanetick has been valuing intellectual property for nearly 20 years. He has been involved at the intersection of patent valuation and transactions such as capital raises, licensing agreements, assignments, patent disputes, spin-offs, and acquisitions.
He has seen deals jeopardized and derailed because unapostillized patent and trademark documents are not accepted by foreign patent offices, courts, or business partners. He decided to help patentees avoid these tragedies by preemptively filing for patent and trademark apostilles.
