DISCUSSION
To establish a prima facie case of obviousness, there must be more than
the demonstrated existence of all of the components of the claimed subject

substitutions required. That knowledge cannot come from the applicants'
disclosure of the invention itself. Diversitech Corp. v. Century Steps, Inc.,
