What is the recording date for a document at the USPTO?

The recording date for a document at the USPTO is the date when the document meeting all recording requirements is filed with the Office. As stated in 37 CFR 3.51, “The date of recording of a document is the date the document meeting the requirements for recording set forth in this part is filed in the Office.” This means that all necessary criteria, including proper identification and fees, must be met for the document to be officially recorded on that date.
