Did Arista Networks trademark "Cloud Networking"?

While reading a fairly unexciting post about "what is cloud networking, I noticed something interesting. In Arista Networks CEO Jayshree Ullal I discovered a cloud networking trademark notice in the following sentence.

To provide an effective network fabric for these clouds requires a next generation of network infrastructure, which we call Cloud Networking™.

So did Arista trademark "Cloud Networking"? I'm not a trademarking expert, and just because you put a TM by a word doesn't make it a trademark.

I'll keep you posted.
