It seems Semtech is not happy about free exposure of their LoRa™®€$£¢฿ technology. Just a quote from a Kickstarter project:
Because the name LoRa® is a trademark of Semtech Corporation; We have had to change the original name of “LoRaCatKitty” to “KittyIoTBoard”
According to http://www.semtech.com/mediacenter/forms/LoRa-Guidelines-for-Customer-Use.pdf prior approval needs to be requested.
