Key Finding: This chart presents the total number of claims for which amendment was granted (rather than the number of actual motions to amend). In most instance, the PTAB denied these motions for substantive reasons; however, in a few instances, a contingent motion to amend was not granted because the original claims were upheld. As with the statistics for the success rate for overall motions, the success rate on a claim-by-claim basis has increased overall from last year’s analysis (3.5% overall). Indeed, through 2017, only 42 claim had been successfully amended, as compare to 160 claims by the end of 2018. More critically, the 2018 statistics alone show a success rate on a claim-by-claim basis of over 18%, a significant jump from the pre-2018 statistics.
