I am asking for this patent. It should be 2023, right ? Or am I missing something ?
As RishiM_IPR states, if the patent prosecution takes over three years, there can be patent term adjustments. To verify this, go to the US Public Pair site, select "Patent Number" and enter "7792728" (without quotes). Once it loads you'll see a tab labeled "Patent Term Adjustments". For this patent, there were "Non-Overlapping USPTO Delays" of 1890 days of which 36 days were considered "Applicant Delays" which don't get adjusted for. The result is 1854 "Total PTA Adjustments".
