PTAB Decisions on Institution

Institution is the gatekeeping step of every AIA trial. The Board asks whether the petition meets the statutory threshold, whether any statutory bar applies, and whether discretion counsels against review. Discretionary-denial practice has changed repeatedly, so these notes describe each decision in its own time and point to current guidance.

Designations and rules change. Before relying on any decision, confirm its current status on the USPTO PTAB pages.
