In the  Dotcom era, 25 years ago, I  purchsed shares of Wi-Lan @ $7.50 in a heartbeat when I saw game-changing potential of the their technology https://www.techtarget.com/searchnetworking/definition/orthogonal-frequency-division-multiplexing#:~:text=Orthogonal%20frequency%2Ddivision%20multiplexing%20is,a%20single%20Wideband%20channel%20frequency.

WLAN reached the $90 range and fell to single digits  because everyone used the tech without paying fees for the patents. Today:   https://www.wilan.com/

Royalton discussed Wi-Lan on the now gone Agoracom Wi-Lan hub at one time.     

After 25 years of picking a few winners that performed well enough to cover the losers and generate a plus. I have POET Technologies stock. It has been a long time between drinks to celebrate a second outsized ROI which is a virtual certainty to occur.
