Trademark examining attorneys will not accept documents for filing (either with or without fees).
If the filer wants a receipt, he or she should provide a card, which will be date‑labeled and handed back to the person delivering the document. When a card is used for receipt, it should include the applicant’s name, the application serial number or registration number, the mark, and the title or a description of the document being filed. The card should also specify the items submitted (e.g., drawing, specimen, fee). See TMEP §303.02(c).
Customer Service Window. The USPTO strongly encourages parties who are hand-delivering trademark correspondence to bring it directly to the Trademark Assistance Center at the address listed above. Use of any patent box for trademark-related correspondence is strongly discouraged, and may result in delayed processing. However, the USPTO will accept trademark correspondence delivered to the Customer Service Window located in the Randolph Building, 401 Dulany Street, Alexandria, Virginia 22314. The USPTO will stamp postcard-type receipts to acknowledge the receipt of correspondence filed at the Customer Service Window. The Customer Service Window is open from 8:30 a.m. until 12:00 midnight, Monday through Friday, except Federal holidays within the District of Columbia.
See TMEP §309 regarding unscheduled closings of the USPTO.
