You might be a little bit confused when you receive this in the mail.
This Response is usually mailed along with a Confirmation Receipt. At first, you may be thinking to yourself, "I never requested for a corrected filing receipt so why did I receive this?" But you will receive this Response automatically when there is something wrong with your priority claim(s). This is usually because:
If your application number(s) and/or its filing date were incorrectly written, you can submit a corrected ADS. The easiest way to do this is to: 1) print out the old ADS; 2) cross out the incorrect information (if needed); 3) write in the corrected information and underline the newly written information (as you would do with claim amendments); and 4) scan the revised ADS and upload it to e-file it. Remember that you may have to pay a processing fee ($35 for micro entity, $70 for small entity).
If you've written the correct application number(s) and its filing date, you may still have made other mistakes on the Domestic Benefit/National Stage Information section of the ADS. A common mistake is not putting in the right application numbers in the right boxes. Remember that the first box under Application Number (in the first row) will always be blank when you initially submit your ADS. But you will need to fill out the Application Number boxes in the second rows and all of the subsequent rows thereafter.
If your application was technically expired (i.e., the prior provisional application was filed within 14 months), then you would have to file a petition to restore the benefit of the provisional application if the delay in filing the instant application was unintentional. This is probably the hardest mistake to fix and can be hefty in cost (the petition fee is $850 for small and micro entities). There is no fee for this, but your petition has to be in writing and should state all of the facts involved and any relevant evidence therefor.
Once all of the corrections are made, then you will receive a new filing receipt citing proper priority information.
