The Patent Trial and Appeal Board issued 50 Final Written Decisions in June. It was a relatively difficult month for patent owners, with the Board cancelling 555 (80.32%) of the instituted claims while declining to cancel 114 (16.50%) of the instituted claims. Patent owners conceded 22 (3.18%) 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%, and the rate of cancelled claims in May was about 48%.

On a per-case basis, no instituted or substitute claims survived in 37 (74%) of the decisions, all instituted claims survived in 10 (20%) of the decisions, and a mixed outcome occurred in 3 (6%) 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:
