If you are a practitioner (e.g., patent attorney or agent) with a registration number less than 25,000, you must respond to a survey letter that was mailed earlier this year to remain on the roll of active practitioners.
If the PTO fails to get a response tomorrow, you will be removed and required to pay a reinstatement fee.
