Wi-LAN Inc. (WiLAN) and Acacia Research Corporation reported their Q1 2017 earnings on May 4, both revealing year-over-year declines in revenue of more than 60 percent. The quarter’s dismal results come amid efforts by WiLAN and Acacia—historically, the two publicly traded NPEs most active in patent litigation among those tracked by RPX—to diversify their activities beyond patent assertion.
