Continued Prosecution Application Receipt Date Determined by Office Facsimile Unit
Note:
The receipt date for a continued prosecution application sent via facsimile is determined by the date it is received at the Office, unless transmitted on a holiday or weekend.

The date of receipt accorded to any correspondence permitted to be sent by facsimile transmission, including a continued prosecution application (CPA) filed under 37 CFR 1.53(d), (available for design applications only) is the date the complete transmission is received by an Office facsimile unit, unless the transmission is completed on a Saturday, Sunday, or Federal holiday within the District of Columbia. Correspondence for which transmission was completed on a Saturday, Sunday, or Federal holiday within the District of Columbia, will be accorded a receipt date of the next succeeding day which is not a Saturday, Sunday, or Federal holiday within the District of Columbia. For example, a facsimile transmission to the Office from California starting on a Friday at 8:45 p.m. Pacific time and taking 20 minutes, would be completed at 9:05 p.m. Pacific time. The complete transmission would be received in the Office around 12:05 a.m. Eastern time on Saturday. The receipt date accorded to the correspondence is the date of the following business day, which in this case, would be Monday (assuming that Monday was not a Federal holiday within the District of Columbia). Note, however, that if the Certificate of Transmission is available (for documents not proscribed by 37 CFR 1.8(a)(2)), then the above facsimile may be considered timely filed on Friday if it contains a Certificate of Transmission and is in compliance with 37 CFR 1.8(a)(1)(i)(B) and (ii).

Certificate of Transmission for Timely Filing on Friday
Note:
If the Certificate of Transmission is available and the document complies with specific requirements, a facsimile transmission can be considered timely filed on Friday.

The date of receipt accorded to any correspondence permitted to be sent by facsimile transmission, including a continued prosecution application (CPA) filed under 37 CFR 1.53(d), (available for design applications only) is the date the complete transmission is received by an Office facsimile unit, unless the transmission is completed on a Saturday, Sunday, or Federal holiday within the District of Columbia. Correspondence for which transmission was completed on a Saturday, Sunday, or Federal holiday within the District of Columbia, will be accorded a receipt date of the next succeeding day which is not a Saturday, Sunday, or Federal holiday within the District of Columbia. For example, a facsimile transmission to the Office from California starting on a Friday at 8:45 p.m. Pacific time and taking 20 minutes, would be completed at 9:05 p.m. Pacific time. The complete transmission would be received in the Office around 12:05 a.m. Eastern time on Saturday. The receipt date accorded to the correspondence is the date of the following business day, which in this case, would be Monday (assuming that Monday was not a Federal holiday within the District of Columbia). Note, however, that if the Certificate of Transmission is available (for documents not proscribed by 37 CFR 1.8(a)(2)), then the above facsimile may be considered timely filed on Friday if it contains a Certificate of Transmission and is in compliance with 37 CFR 1.8(a)(1)(i)(B) and (ii).
