Okay, let's sort the chaff
a Podference is : "Downloadable or non-downloadable podcasts [..]; Downloadable or non-downloadable video recordings [..]; Downloadable or non-downloadable written articles"
In other words, videos or documents that can or cannot be downloaded. That the subject is supposed to be technical is irrelevant.
So, my question is : how can you trademark something based on stuff that is not only not yours, but pre-existing since practically the beginning of the Web ?
I might as well push for a trademark on Monettference, where I blather on about any specific subject. Who cares ? It's a video, like the gazillion other videos that are out there. Each and every YouTube channel could push for <channel>ference and what would change ? Nothing.
This is marketing at its finest. Requalify something that already exists for your own benefit. It costs nothing and changes nothing but might increase "brand awareness".
Yes, I have an increased awareness of just how stupid Dell is now, mission accomplished.
