Interesting that the defendants state this in such certainty BEFORE the discovery starts:

From Defendants Doc 309:

Permitting unrestrained discovery in this complex case before a Markman ruling is issued, will be extraordinarily burdensome and oppressive on the Defendants, ...

IF I was a major shareholder (institutional or otherwise) of any of these companies (defendants) maybe I would be 'concerned' about the admitted concern of cost of discovery, and 'suggest' that the BOD 'settle' quickly.

Otherwise, is spending time and money in an "extraordinarily burdensome and oppresive" venture a best use of company rescources?

I would be concerned if they went ahead on such an "extraordinarily burdensome and oppresive" venture, possibly affecting share price, wouldn't you? Especially since these defendants are already aware of the "extraordinarily burdensome and oppresive" nature of complying with the COURT ORDER.....
