You will find MRF (Motorola) or 2SC (Toshiba or other Japanese mfg)
transistors.

I'm not sure that wording is fair.

By definition, application notes are done by a semiconductor manufacturer
to sell the devices. They aren't selling design, they are selling the
transistors or ICs. If an application note sells more devices, then
it's a success. Note that in many cases for ICs, there is a fairly fixed
means of using the IC, which was seen by the manufacturer from the start.
If they didn't show you how the IC was intended to be used, then the IC
isn't of much use.

If semiconductor manufacturers were expecting credit and/or royalties,
they'd either not be giving out the application notes.
