The patent holding firm which was created by Apple, BlackBerry, Ericsson, Microsoft and Sony to purchase thousands of foundation telecom patents from Nortel dubbed the Rockstar Consortium, is set to wind down operations after the partners agreed to sell much of Rockstar’s patent portfolio to IP risk mitigation company, RPX. According to The Wall Street Journal, the sale will see RPX pay roughly $900 million for more than 4,000 patents.

Furthermore the deal is said to include “the bulk” of Rockstar’s portfolio though it remains unclear which patents will be held back and how they will be disposed of. Part of the agreement stats that Rockstar will end all of its ongoing litigation including suits against companies such as LG, HTC and Huawei.

For those of you who didn’t know, RPX is a publicly-traded patent consortium that purchases and licenses patents on behalf of its members. Among the members in the consortium are tech giants Google and Cisco. The members of the consortium can leverage the portfolio to defend themselves against any allegations of infringement. Unlike other patent troll companies, RPX has pledged not to use the patents in their portfolio for any offensive action. RPX CEO, John Amster, said the following in a recent statement regarding the matter:

This is the biggest syndicate of its kind and its formation proves that companies can actually collaborate in... cooperative licensing at scale.
