Can an abandoned application still be used as a priority document?
Yes, an abandoned application can still be used as a priority document for subsequent applications, provided that the priority claim is made within the specified time limits. The abandoned status of the earlier application does not affect its ability to serve as a basis for priority. For more information on priority claims, refer to MPEP 201 and MPEP 211.
