Problems Using the Patent Full-Text and Full-Page Image Databases

Please send email concerning the operation or content of these Web patent databases to the Database Help Desk at  www@uspto.gov.

If you can access the main PTO Web site, but cannot access any of the Patent Grant Database Quick Search, Advanced Quick Searching, or Patent Number Searching pages, your workstation or organization may have been denied access to the Web Patent Databases pursuant to the policy stated on the "Important Notices" Web page. To determine if you have been denied access, you can check the Denied List for your computer's IP address.

(Your IP address is the only means by which you are known to the PTO servers -- server logs do not contain your email address or any other personal identifying information. If you do not know your computer's IP address because you are behind a firewall, do not have a fixed IP address, or for any other reason, you can find your current IP address by using an "IP reflector," such as http://www2.simflex.com/ip.shtml or http://www.dslreports.com/ip.)

If you are an individual whose individual IP address has been denied access: to seek to have your access restored, please send email including your workstation and firewall or gateway IP addresses (consult with your network administrators if necessary), and describing the steps you have taken or will take to insure that future violations of the USPTO access policy will not occur, to the Database Help Desk at www@uspto.gov.

If you are a member or employee of an organization which has been denied access: please do not send individual email to PTO. Instead, please have your network administrator or a person holding authority over your organization's network operations send email including your firewall, gateway, or workstation IP addresses, and describing the steps you have taken or will take to insure that future violations of the USPTO access policy will not occur, to the Database Help Desk at www@uspto.gov.
