Sitting on a patent, not implementing it, while also not allowing others to implement it, is a form of patent trolling.
Hell I’d even go as far as to call what Qualcomm does with their 4G/5G patents, trolling (they basically offer to sell patent licensing but it’s generally much more expensive to get the license AND develop+manufacture your own modem with it than to buy modems from Qcom directly, which is essentially stifling any potential innovation on the modem market).
