TOTAL TIME _ 5.25 hours
In addition, Power Integrations estimates that it will need approximately 2.5 hours to
cross-examine Fairchild’s witnesses, and requests a total of 1.25 hours to open and close.
Power Integrations thus presently estimates the total trial time for its validity case to be
9.0 hours. These time estimates presume Fairchild is limited to the prior art identified at
the first trial and the contentions regarding that art expressly disclosed in its expert
reports. Should Fairchild be allowed to present all the prior art and contentions identified
in its November 3, 2006 motion concerning additional prior art references, Power
Integrations believes the necessary trial time will be substantially greater.
Contact information and a further description of the testimony for Power Integrations’
live witnesses is below. These individuals can be reached through Power Integrations’
litigation counsel. .
