What are the character encoding requirements for sequence listings in ASCII text files?
When preparing a sequence listing as an ASCII text file for patent applications, it’s crucial to use the correct character encoding. According to MPEP 2425:
“The ASCII text file must be in compliance with WIPO Standard ST.25 (1998) and must have a character set limited to ASCII characters 33-126 and 10, 11, 12, and 13 in accordance with 37 CFR 1.824(a)(2).”
Here’s a breakdown of the character encoding requirements:
- Use only ASCII characters 33-126 for text content
- ASCII characters 10 (line feed), 11 (vertical tab), 12 (form feed), and 13 (carriage return) are allowed for formatting
- No other characters or encodings are permitted
It’s important to note that using any characters outside this specified range may result in processing errors or rejection of the sequence listing. Ensure your text editor is set to use ASCII encoding when preparing and saving the file.
