Narrative:

We were holding short of runway 22R on taxiway west, waiting for a B767 to take off. After the B767W was cleared to take off, we heard 'runway 22R at taxiway position and hold, caution wake turbulence behind departing B767.' I read back 'position and hold runway 22R at west.' I initiated the before takeoff checklist as the captain moved the aircraft into position on runway 22R at taxiway west. As we turned to the line-up position, the captain mentioned seeing some lights turning on over his left shoulder, but we had turned too far to be able to see anything behind us. I heard the control tower working aircraft for landing on runway 22L and one in the visual pattern for runway 22R, but there were not any more calls to the aircraft on the ground. We sat for about 1 min in position when the tower told us to clear the runway. The tower controller then stated that we had not been authority/authorized to be on it. As we were taxiing clear of the runway, the tower controller told a hawker jet to also clear the runway. The hawker jet had been holding in position on runway 22R but from the full length position. The aircraft from the visual pattern landed. After a few mins we were cleared back onto the runway and took off without incident.
