What are the requirements for translating a sequence listing in a PCT application?
The requirements for translating a sequence listing in a PCT application depend on the international filing date:
- For applications filed on or after July 1, 2022: An English translation is required for any Sequence Listing XML containing non-English language values for language-dependent free text qualifiers, in accordance with 37 CFR 1.831 through 1.834.
- For applications filed before July 1, 2022: A sequence listing does not need to be translated if it complies with PCT Rule 12.1(d) and the description complies with PCT Rule 5.2(b).
As stated in the MPEP:
“For international applications having an international filing date on or after July 1, 2022, an English translation is required for any sequence listing in XML format (“Sequence Listing XML”) containing non-English language values for any language-dependent free text qualifiers in accordance with 37 CFR 1.831 through 1.834.”
This distinction is important for applicants to ensure compliance with translation requirements based on their application’s filing date.
