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. If the above patent used the word "comprising" instead of "consisting of", then the third party's pencil-plus-eraser would be infringing.

Famous quotes containing the words open and/or transition:
“But when with moving accents thou
Shalt constant faith and service vow,
Thy Celia shall receive those charms
With open ears, and with unfolded arms.”
—Thomas Carew (1589–1639)
“There is not any present moment that is unconnected with some future one. The life of every man is a continued chain of incidents, each link of which hangs upon the former. The transition from cause to effect, from event to event, is often carried on by secret steps, which our foresight cannot divine, and our sagacity is unable to trace. Evil may at some future period bring forth good; and good may bring forth evil, both equally unexpected.”
—Joseph Addison (1672–1719)
