How can I access a Sequence Listing for a patent or patent application?

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.

According to MPEP 2419.02, there are two main ways to access a Sequence Listing for a patent or patent application:

1. Online Access: The Sequence Listing is available electronically from the USPTO website at https://seqdata.uspto.gov.
2. Request from USPTO: You can request an electronic copy of the Sequence Listing from the USPTO. However, this option requires payment of a fee as set forth in 37 CFR 1.19(b)(3).

The patent or patent application publication will include a SEQUENCE LISTING statement providing this information for easy reference.
