I'll tell what I think would light a fire under the Js to settle:

IF our team filed a motion for summary judgment. 

I believe Ron had pointed out how that event spurs settlements BEFORE the Judge rules.  If they beat the ruling (assuming they think there is a chance the Judge would rule in our favor), it's their ONLY opportunity to save face.  They could still settle without announcing to the world (or having the Judge announce) that they were indeed infringing, and that they had wasted company (their shareholders') resources fighting an unwinable battle.  And there is also the spectre of an injunction (which would probably be reiterated with the motion on the merits).

JMHO,

SGE
