Filing Date Not Assigned for Unresolved Non-Compliance
Note:
If a reexamination request fails to correct identified non-compliance after response, it will not receive a filing date.

If the requester timely responds to the “Notice of Failure to Comply with Ex Parte Reexamination Request Filing Requirements,” the CRU LIE and CRU Paralegal will check the request, as supplemented by the response, for correction of all non-compliance items identified in the notice. If any identified non-compliance item has not been corrected, a filing date will not be assigned to the request papers. It is to be noted that a single failure to comply with the “Notice of Failure to Comply with Ex Parte Reexamination Request Filing Requirements” will ordinarily result in the reexamination request not being granted a filing date. 37 CFR 1.510(c) provides that “[f]ailure to comply with the notice may result in the ex parte reexamination request not being granted a filing date.” Thus, absent extraordinary circumstances, requester will be given only one opportunity to correct the non-compliance. Similarly, if the response introduces a new defect or deficiency into the request papers, the ex parte reexamination request will not be granted a filing date absent extraordinary circumstances.

Check Returned for Insufficient Funds After Filing Date Assigned
Note:
The Office must notify the requester if a check is returned due to insufficient funds after assigning a filing date, and provide time to correct the issue.

After a filing date and control number are assigned to the request papers, the examiner reviews the request to decide whether to grant or deny reexamination. If, in the process of reviewing the request, the examiner notes a non-compliance item not earlier recognized, the examiner will communicate with the CRU Supervisory Patent Reexamination Specialist (SPRS) detailing any such non-compliance item(s). The CRU SPRS will discuss the case with an appropriate OPLA Legal Advisor. Upon confirmation of the existence of any such non-compliant item(s), OPLA will issue a decision vacating the assigned reexamination filing date.

This category also includes instances where the Office becomes aware of a check returned for insufficient fund or a stopped payment of a check after a filing date has been assigned, and prior to the decision on the request for reexamination.
