Software patentability is limited in a lot of places, can this actually be an argument in favour of doing things using SDR?

"Software patentability is limited in a lot of places"

In Europe, the new Unified Patent Court (UPC) will probably rubberstamp them, using the "as such" and the "technical effect" loopholes. Without any appeal possible to the European Court of Justice.

Sorry, replied to one of the child posts. It's not a software patent, it's a radio modulation patent: https://patents.google.com/patent/US20160094269A1/en and I'm not really that confident that it would be struck down if challenged; from what I'm remembering from digging into it, it is actually a pretty novel form of modulation that has some nice properties for the specific application they're using it for.

It's not about software, it's the underlying technology.

For example, LoRa uses spread spectrum and there are many patents on spread sprectrum in general (don't know about LoRa in particular).

But in SDR, the "underlying technology" of radio modulation, spread spectrum, etc is your software, no?

[tonyarkles]

It's a very specific form of spread spectrum that they've called Chirp Spread Spectrum and as far as I recall it is actually a pretty novel form of modulation.

Could be a few GNURadio templates they are patenting?
