You may conduct a free online search of the USPTO database at the Public Search Facility (Madison East, 1st Floor; 600 Dulany Street, Alexandria, Virginia) between 8:00 a.m. and 8:00 p.m. USPTO personnel may not conduct trademark searches for the public. Private trademark search firms will conduct searches for a fee. The USPTO cannot aid in the selection of a search firm or an attorney. Search firms are often listed in the yellow page section of telephone directories under the heading "Trademark Search Services" or "Patent and Trademark Search Services."
Adding an extra layer of two-facedness to life is a step backwards, not forwards, IMHO. Speaking from experience of what it is like to be watched constantly (in a given context, community etc, pre-internet) and the damage done to one's humanity is SEVERE. Or some derivation of 'severe'. This is the thing: depending on how conformist one is [born to be]. Hence why scared, overly-conformist people who think this makes them safe, think that no harm can be done by being watched all the time. They value conformity and don't realise that taking that too far makes humans into robots and creates fascism etc.
But fans did figure out relatively early on that they were all looking in one direction, before this challenge was ever issued. Despite being on opposite ends of the map, they were all staring toward a central point. There was a theory that this might be a new season 5 mystery to be uncovered, but in truth it seems it was only leading up to this challenge.
It is also amazing how this article was surfaced via my Google Now because Google knew I was interested in this kind of stuff. If Google was evil, they would never surface this type of article that has a opposite position to Google. Also that Ad shown at the bottom of this article was probably targeted based on Google data which ultimately helps you as the author monetize the traffic you are getting.
