Good points again on all, BP. For all we know, UPLD may be serving dozens of cease & desist letters, while building multiple cases against the many patent infringers. They YHOO case took awhile to build and was more public, but that's not to say it can't be revisited, nor many other companies are at risk of public suits.
Patents are for IP protection and proactive defense of business assets. That patent portfolio is platinum and would be massive for the right tech company to have that's heavy in Mobile, AR, VR, and ad tech.
Only two come to mind that matter most: Facebook and Google. + Both have a TON of cash reserves right now and could offer up stock too in a great deal. FB bought Occulus for over $1B and a $1B deal for UPLD assets + NOLs + Patents would not be too far-fetched here, nor expensive. It would bolster an FB or GOOG defenses for years and decades to come.
