Resolution: In order to resolve this issue, the best thing to do is to delete the project and start again after ensuring the ST.25 file you are importing is valid. WIPO Sequence was not designed to perform validation checks for ST.25 sequence listings and assumes that only valid ST.25 files will be imported into a project. The USPTO created a tool to create check sequence listings for compliance with ST.25 called Checker: https://www.uspto.gov/patents/basics/types-patent-applications/utility-patent/checker-version-446 |
