The Patent Trial and Appeal Board issued 41 Final Written Decisions in May. It was a relatively patentee-friendly month, with the Board cancelling 269 (48.04%) of the instituted claims while declining to cancel 287 (51.25%) of the instituted claims. Patent owners conceded 4 (0.71%) instituted claims through motions to amend or disclaimer in cases reaching a final decision. For comparison, the cumulative average rate of claims cancelled in final written decisions is about 75%.

On a per-case basis, no instituted or substitute claims survived in 20 (48.78%) of the decisions, all instituted claims survived in 14 (34.15%) of the decisions, and a mixed outcome occurred in 7 (17.07%) of the decisions. A mixed outcome occurs where at least one instituted or substitute claim remains patentable, and at least one is cancelled, in a Final Written Decision.

The overall cumulative instituted claim survival rate, broken down by technology center, is as follows:
