Foreign patent laws in this regard may be much more restrictive than US laws. The Disclosure Document will be preserved by the PTO for two years after its receipt. After that time, it will be destroyed unless it is referred to in a separate letter in a related patent application filed within the two-year period. Acknowledgment of such letters will be made in the next official communication or in a separate letter from the Patent and Trademark Office. Documents without the full fee will be returned.
Fees are subject to change annually.
The IAS is under contract with and is funded with State appropriations.
