How are lengthy “Sequence Listings” published in patents and patent application publications?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Lengthy “Sequence Listings” (i.e., at least 600 Kb or about 300 typed pages) are no longer printed with paper and composed electronic image versions of patents and patent application publications. Instead, they are published only in electronic form and made available on the USPTO sequence homepage.

As stated in the MPEP: The “Sequence Listing” will only be published in electronic form and will be available on the USPTO sequence homepage ( https://seqdata.uspto.gov ) as an ASCII plain text file.
