How do I - view Maintenance Fees?
Maintenance Fee data is available Monday - Friday from 5:30 AM to Midnight E.T. and Saturdays, Sundays, and Holidays from 7:30 AM to 8:00 PM E.T. Information about maintenance fees may also be obtained through PAIR. Patentees and members of the public viewing this data should double check the information with the Maintenance Fee Division, before, for example, assuming that 'no fees to pay' means that all of the fees have been paid. Such a message may also appear if the period for payment of maintenance fee has expired and the patent has now expired.
Maintenance Fees - Retrieve fees to pay provides information about unpaid maintenance fees and allows you to make your payment online by credit card, electronic funds transfer (EFT) or deposit account.
Maintenance Fees - View payment windows provides information regarding maintenance fee due dates.
Maintenance Statement - View ... year payment window provides information regarding maintenance fees previously paid for the payment year selected. When trying to view a statement, if the error message "no fees pending on finance" appears, the fee has not yet been paid. Use the Maintenance Fees - View payment windows search option to display the dates for the most recently due maintenance fee. If the most recent fee due has not been paid and the 'payment window closing date' has past, the patent is considered expired as of that 'closing date', with the exception of certain cases where a petition has been filed (recorded in the File History/Transaction History). If a petition has been filed and 'granted', the patent remains in tact but the maintenance fee statement will not be viewable because the fee was paid with the petition fee. Please refer to the Patent Maintenance Fees Storefront for further information.
How do changes to my Customer Number data affect my PCT applications?
The customer number associated with a PCT application will be used only for Private PAIR access and will not be used for the correspondence address. Therefore any changes to the customer number will not affect the PCT application.
How do I associate my applications with my customer number?
To associate existing patent applications to a Customer Number, you can complete and submit the Customer Number Upload Spreadsheet located at http://www.uspto.gov/patents/process/file/efs/guidance/register.jsp. Download the Customer Number Update Template and after filling out the MS Excel spreadsheet, save it on a USB Memory Stick or CD and mail it to the Patent EBC at
Mail Stop EBC
P.O. Box 1450
Alexandria VA 22313
Another method to associate an application to a customer number is to submit the Change of Correspondence Address form (SB/122) located at http://www.uspto.gov/web/forms/sb0122_fill.pdf. Unlike the Customer Number Upload Spreadsheet where multiple applications/patents can be listed, the Change of Correspondence Address form can be used to only associate a single application to a customer number. Only the customer number should be indicated on the SB/122 form with physical address left blank. Customer number associations using the SB/122 form are processed by the Applications Assistants Unit or a Technology Center. The EBC processes the automated Upload Spreadsheet.
Using the spreadsheet to change the correspondence address and/or maintenance fee address on applications is a legal record of change. This spreadsheet MUST be accompanied by a cover letter signed by someone who, for each application or patent listed on the attached spreadsheet, is either: (1) the Pro Se applicant [definition in new window] , or the Sole Inventor, where there is not registered Patent Attorney or Agent of Record, or (2) an Attorney or Agent of Record.
Note, however, a practitioner is not necessarily of record in an application when the practitioner is associated with a customer number and the customer number is associated with an application. A practitioner is only of record in an application when the power of attorney is given to the practitioner or to a list of practitioners associated with a customer number (and the practitioner is associated with the customer number).
How do I view or change the correspondence address and list of individuals associated with my customer number?
From the Private PAIR search screen, select your customer number from the drop-down list below View Customer Number Details and click the Search button.
To submit a paper change request, click the "Request for Customer Number Data Change" link below the Customer Number Details screen to display and print PTO/SB/124A in PDF format. Use this paper form to mail or fax changes in the correspondence address or list of individuals associated with a Customer Number. Submit the completed form via fax to (703) 308-2840 or mail to:
Mail Stop EBC
P.O. Box 1450
Alexandria, VA 22313
To submit an online change request, click the "Request Data Changes" button below the Customer Number Details screen. This returns the Request Data Changes for Customer Number online form for changes to Customer Number Address, addition of individuals, or deletion of individuals from the Customer Number.
What is the "Publication Review" option?
The "Publication Review" button appears in the Private PAIR and allows applicants to enter and submit Correction Requests to data shown on the Publication Review screen to match the data set forth in certain previously filed application papers. Correction Requests must be received earlier than fourteen (14) weeks prior to the projected publication date to be reflected in the patent application publication. This screen cannot be used to submit Correction Requests in applications filed under 35 U.S.C. 371 (i.e., national stage applications). This screen also cannot accept special characters, e.g., umlauts. Additional information can be found here: http://www.uspto.gov/patents/process/status/private_pair/pub_review_instructions.jsp

How do I - search to determine if there is/was a reexamination for a patent?
Retrieve the patent information from Public or Private PAIR by using the Patent Number search option. Then, select the "Continuity Data" tab or search option, and review the "Child Continuity Data." If a reexamination was requested for the patent or was ordered at the initiative of the USPTO, and is pending or concluded, then the reexamination proceeding(s) will be listed in the Child Continuity Data section and may be identified by the Control Number of the reexamination proceeding, which begins with "90" or "95", i.e., 95/000,000. Select the Control Number link to view information regarding the reexamination proceeding, such as the current status of the proceeding.
Reexamination proceedings may also be searched directly in PAIR by using the Control Number search option.

The International Registration Publication Date is the date WIPO published the international design application.

An international design application satisfying the requirements under the Hague Agreement for international registration will be assigned an international registration number by WIPO, which begins with the series code “DM/nnnnnn”. Thereafter, the international design application will be published by WIPO.
What is the Hague Agreement?
The Hague Agreement refers to the Geneva Act of the Hague Agreement Concerning the International Registration of Industrial Designs. The Hague Agreement is an international registration system which facilitates protection of industrial designs in member countries and intergovernmental organizations (also referred to as “Contracting Parties”) by means of a single international design application filed either directly with the International Bureau (IB) of the World Intellectual Property Organization (WIPO) or indirectly through the applicant’s Contracting Party.
Information concerning the Hague Agreement, including geographic coverage and a guide for users, is available at WIPO’s Web site http://www.wipo.int/hague/en/
Where can I find more information on the Hague Agreement?
More information can be found on the USPTO website - http://www.uspto.gov/patent/initiatives/hague-agreement-concerning-international-registration-industrial-designs
How do I search for an International Design application?
International design applications received by the USPTO are assigned a 35-series application number (“35/nnn,nnn”). PAIR users can search for a 35-series application by using the “Application Number” search found under the “Search for Application” section in PAIR. In addition, PAIR users can search for a 35-series application corresponding to a published international design application designating the United States by the international registration number using the “International Design Registration Number” search found under the “Search for Application” section in PAIR.
