Open Transition
An open transition usually uses the word "comprises" or "comprising". This is the broadest form of transition, as it does not limit the preamble to whatever elements are identified in the claim.

—Rheta Childe Dorr (1866–1948)
“Power ceases in the instant of repose; it resides in the moment of transition from a past to a new state, in the shooting of the gulf, in the darting to an aim.”
