Rockstar Consortium, a patent-holding company headed by Apple, has agreed to sell more than 4,000 mobile patents for about $900 million.
Apple and partners Microsoft, BlackBerry, Ericsson, and Sony paid $4.5 billion for more than 6,000 patents from Nortel four years ago in order to help protect against litigation.
The companies are selling two-thirds of the patents to RPX Corp., which is another patent-focused company that protects companies from lawsuits. RPX plans to license the patent portfolio to a syndicate of 30 technology companies, including Google and Cisco, according to the Wall Street Journal.
The syndicate members contributed the bulk of the $900 million in order to purchase the patents. In addition to the patent sale, Rockstar will settle patent-related lawsuits it has filed against Android device makers, including Samsung, Huawei, HTC, and LG. Terms of those settlements were not disclosed. Rockstar Consortium will hold onto about 2,000 of the old Nortel patents, which the Journal described as the “most valuable” of the bunch.
