A dismissal is not a denial. It means the petition was incomplete or not quite right, and it can be renewed. But every renewal is more time, and the extra delay can be what pushes a case past the next threshold.
The new reason: explaining the delay
Since 13 August 2026, a petition filed more than a year after the deadline has to explain the entire period of delay, not just state that it was unintentional. Many of the most recent dismissals are the USPTO asking for exactly that. That one is about timing. The rest of the list is paperwork.
The paperwork reasons
The corrected ADS does not mark its changes. A corrected ADS has to show what changed against the most recent filing receipt: additions underlined, deletions struck through (37 CFR 1.76(c)(2)). A claim added without underlining, or strikethrough of something that was never in the Office's records, is enough for a dismissal. This was the most common paperwork reason in the decisions we read.
The continuing application fee was not paid. A claim to an earlier nonprovisional application can trigger the fee under 37 CFR 1.17(w) when the application is filed more than six years after the earliest benefit date. A petition without it is incomplete.
The chain has a gap. Every application in between has to claim the one before it. If an intermediate application never referred back, the chain is broken, and the claim cannot reach past it.
The claims are out of order, or the signature is wrong. Small things, but each one sends the petition back.
No petition was needed. Some petitions are dismissed because the claim was still inside the four-month or sixteen-month window, or because the change, such as a corrected relationship type, only needed a corrected ADS. That is a fee and weeks of waiting spent on a step that was not required.
It needed a different petition. If the later application was filed more than twelve months after the earlier one, a late claim cannot fix it. The priority right itself has to be restored under 37 CFR 1.55(c) or 1.78(b), which is only available within a two-month grace period.
Avoiding the petition altogether
IPPrep Pro does not draft petitions. Its job is to make sure you don't need one. It builds the ADS priority section from USPTO data, checks each claim and each link in the chain against the Office's records before you file, and tells you whether the continuing application fee applies, so the claim goes in right, and on time. More on what a late priority claim costs.
