A patent on backup up files?! Oh frak this system is broken beyond repair...

For anyone wondering about the specifics:

"For example, there was a dispute about whether Whatsapp uses a technology that Blackberry holds a patent on when sending a chat history to a third party via email."

The actual legal claims are in this document: http://docs.dpaq.de/13322-031127684372.pdf

Chat history isn't stored server side, so gdpr doesn't apply here.

I always wondered about that. If a closed source app keeps my data in their silo, but I own the hardware their software runs on, I can't do anything with GDPR? Aren't they the controller if they run the software?

Exactly. We're not owners of that data, they are. Should be an extension of the regulations IMHO.

That's also my "HO" but I was more wondering how to interpret this from a legal perspective. I've read large parts of the GDPR law but don't (at least off the top of my head) remember anything that would say either way.
