Possibly Andrea Koch influenced some people at POET?
Attention, "Powered by Android" is no registered trademark.
In the TESS database of the Unites States Patent and Trademark Office there are 809 trademarks registered with "Powered by...", and even 10 "Intel inside".
Clearly registering a trademark is one - important - side, but just a start. The effort and costs to make it public, to "sell" and to defend it is the key.
I am sure this registration is showing us the committment of POET (and their licensees ) to market it. This is highly interesting, as - compared to most other brands this is not about physical "things" (like Coke) or part of a final physical thing (like Goretex). Here they are promoting an IP ecosystem, a technology, a philosophy! I guess this is a highly interesting playground for marketing people, and I hope POET will find the best PR-company to develope this brand.
OT: Funny, where are Harry or TG these days? :-)
