Dr. Houh’s new combinations of Chu ‘684 with Chu ‘366 or Chen, (1) do
not lend support to Petitioner’s manner of combining the art, (2) lack support in the
teachings of the asserted references themselves, and (3) render the proposed
system deficient for its intended purpose of accurate and reliable call routing.
These factors clearly belie the Petition’s assertion that its combinations
would be obvious to a skilled person. Indeed, the very need for Dr. Houh to devise
numerous ad hoc solutions to various conflicts between the use of private and
public numbers in Petitioner’s proposed combinations, strongly urges the
conclusion that Petitioner’s manner of combining the elements would not be
obvious.
Dr. Houh was asked about whether using a PSTN prefix digit (e.g., “9”)
would be a solution to allow a PBX extension (“private number”) to pass through
the reformatting step without being changed or misinterpreted. Dr. Houh agreed
that it would be easy to reformat a public number after it was identified by a prefix
stating, “If the user dialed nine, the rest of the digits could be easily passed through
the algorithm of the Chen”. Ex. 2044 at 155:8-156:4. While this manner of
combining the references (e.g., reformatting after step 608 in Chu ‘684) is clearly
superior to the contorted and artificial ordering of Petitioner’s combinations, it
does not practice the method of the challenged claims.
