I implemented OF over 15 years ago, and even back then the OF trademark had laps...

And? (TM) is used to denote unregistered trademarks, as opposed to (R) for registered trademarks.

Which is in any case irrelevant. Open Firmware != open firmware.

The Open Firmware Working Group's website at https://www.devicetree.org/open-firmware/home.html mentions the OpenBoot(tm) trademark, but uses Open Firmware without any signifier. (and they should know)

Given that there's apparently no protection at all, I see no reason why I'd have to adhere to your wish to use 1275's way of writing O and F in upper case. So yes, I _can_ call it open firmware.

I don't think you understand how this works. My calling it "Open Firmware" has nothing to do with its trademarked status. It is a proper noun.

Open Firmware != open firmware.
