PTAB hearings are held in person unless the Board finds good cause for a party to appear virtually; one party's approval does not establish good cause for another party.

Hearing Room Equipment
PTAB provides specified presentation equipment, but parties must bring their own laptops, store materials offline because hearing rooms lack internet access, and obtain prior authorization for animation or video demonstratives.

Remote Panel Demonstrative Visibility
Parties must make demonstratives available to every APJ, including judges participating remotely, and identify the demonstrative clearly during argument.
