(9) Changes in How Papers May be Filed in the Patent and Trademark Office Beginning April 21, 1992, an improved service will be offered to people who wish to file papers directly with the Patent and Trademark Office (PTO) by extending the hours of operation for the Attorneys' Window located in Room 1B03 of Crystal Plaza Building 2, Arlington, Virginia. The current hours of operation are from 8:30 a.m. to 5:00 p.m., Monday through Friday, except Federal holidays within the District of Columbia. The change will extend the hours of operation until 12:00 midnight on Monday through Friday, except holidays, on a trial basis. If, after six months, usage does not warrant retaining operations until midnight, the hours of operation will be reduced. This change will provide walk-up, personalized service to firms and individuals who are filing documents with the PTO. The PTO will continue to stamp postcard-type receipts to acknowledge the receipt of papers filed at the Attorneys' Window. Also, effective on April 21, 1992, the PTO is discontinuing the use of drop boxes in the lobby of Crystal Plaza Building 3, Arlington, Virginia, and at the main entrance of the Department of Commerce Building, Washington, D.C. (37 CFR 1.6(c)) as means for receiving papers. These changes will provide improved services with respect to receipt and processing of documents while, at the same time, overcoming problems with the present arrangement. Problems encountered with the present arrangement for the drop boxes have occasionally made it difficult to determine the dates of actual deposit of papers. For example, there have been many incidents of papers being found outside of the drop boxes (e.g., on the floor of the main lobby of the Department of Commerce Building, on the guard's desk, on a nearby table, etc.). On occasion, the PTO and/or filers have been denied access to the drop box at the Department of Commerce by building security guards due to a special event taking place in the lobby. Provisions are also available for filing papers through the use of the certificate of mailing (37 CFR 1.8) and the Express Mail (37 CFR 1.10) procedures. March 17, 1992 HARRY F.
