How many posts on this?  So I ask the obvious question:  How in the world would Judge Ward KNOW the meaning and intent of the terminology in the original patent filings if he were not of appropriate ability in the field at the time of original patent application AND had extraordinary recall?  He HAS to depend, to a large degree I would think, on the input of others regarding certain terminology.  Who to depend on?  Someone with credibility, regardless of their employer (recognizing that the person's credibility would be severly damaged if they "mis-spoke" in their testomony - i.e., no more such gigs).

I suspect that, regarding any terminology in question, Judge Ward is very dependent on others simply because there is no way he could be expected to KNOW.  So, value of expert testomony?  I'll add that he probably has access to his own "experts".

In considering the above, remember that the original patent applications were submitted nearly twenty (20) years ago, not recently.  And in a very dynamic (ever-changing) environment.

JMHO,
