We filed an application that included a 3K sequence listing (SQL) text file on August 5, 2020. The N417 electronic acknowledgement receipt lists the SQL file as a submitted document and provides a hash/message digest for it. On August 18, 2020, we received a Notice to Comply With Requirements For Patent Applications Containing Nucleotide and/or Amino Acid Sequence Disclosures that indicated that the USPTO had *not* received the sequence listing. When we called the customer assistance center on August 19, 2020, the agent that we spoke with acknowledged that a sequence listing had been submitted but "could not find it anywhere"--it had vanished. We separately checked Patent Center's Documents & Transactions and the Supplemental Content tab for the application in question and there was no trace of it (this was also on August 19, 2020). Today, we checked again, and there are two sequence listing files in the supplemental content tab for the application--one corresponds exactly with the uploaded version, and the other only differs in that the "unassigned" value for field <140> has been replaced with the actual application serial number.
For reasons that are not clear to me, downloading the sequence listings from the supplemental content tab results in files with a ".RAW" extension, which is an image format extension. The content is entirely text content, however. It should be a ".TXT" extension.
There is clearly a bug of some sort in Patent Center that caused this sequence listing to go walkabout for 2-3 weeks, with the USPTO unable to obtain any clear picture of its status. Materials that are submitted through Patent Center *need to be made available the same day that they are submitted* so that practitioners can download evidence of what was submitted in case there is a dispute later. A 3-week delay before a dinky little text file (414 words, < 3000 characters in length) makes it into the supplemental content or documents tab for a matter is incomprehensible. There's simply no reason for any delay for something like this.
In this case, the delay was so extreme that the USPTO actually reviewed the application file for formalities and erroneously sent out the Notice to Comply before the SQL submission finally bothered to show up in the file.
This needs to be fixed ASAP.
