What is the size threshold for separate publication of sequence listings?

The size threshold for separate publication of sequence listings is 300 KB. MPEP 2435 specifies:

“For applications filed on or after September 16, 2012, having a sequence listing that is 300 KB or less in size, the sequence listing will be published as part of the patent document. If the sequence listing is greater than 300 KB in size, the patent document will include an incorporation-by-reference of the electronic version of the sequence listing, and the sequence listing itself will be published as a separate document.”

This threshold determines whether the sequence listing is included in the main patent document or published separately as an XML file on the USPTO website.
