< If the inventor of the patent says that you can not determine infringement without propietary documentation how do we know that they infringed in the first place, since they have never allowed us to view that documentation.>

You need to do some reading.

<As required by Patent Local Rule 3-1, the infringement contentions specifically set forth where each limitation of each asserted claim is found within each accused product, and are therefore sufficient. Barco is also wrong on the law that Defendants are limited to proving their case with evidence identified in their infringement contentions. It would be illogical to have such a limitation, since contentions must be served early in the case, long before discovery has been completed. All of the information identified in Defendants’ infringement contentions is relevant and admissible to prove infringement of the ‘336 patent claims. >
