I would like to use the term "non pliable" in the claim preamble which does not appear in the specification. However the term "pliable" does appear in the specification but is not specifically defined.
1. A method for converting a non pliable widget into a pliable widget, the method comprising: compressing the widget; heating the widget; applying a force to the widget.
How a term not present in the specification is interpreted when used in a preamble.
Do the claim's steps define the meaning of the terms "non pliable" and "pliable" in the preamble?
Can a claim be deemed indefinite because of use of a term in a preamble which is not present in specification?
Howe likely it is that such claim will be invalidated in court during a potential patent challenge?
