Can a restriction requirement be repeated after being withdrawn?

Yes, a restriction requirement can be repeated after being withdrawn. According to MPEP 811.03, “Where a requirement to restrict is made and thereafter withdrawn as improper, if restriction becomes proper at a later stage in the prosecution, restriction may again be required.” This means that even if a restriction requirement was initially made and then withdrawn due to being improper, it can be reinstated if it becomes appropriate later in the patent examination process.
