Fresh EEStor Controversy

Black & Decker. Boeing. Snap-On Tools. Vextrex Corporation. Lockheed Martin. According to new documents released by the USPTO, EEStor's use of the EESU trademark began with "budgetary quotes" submitted to these prospective customers going back to 2002/2003 time frame.  But are price quotes sufficient activity to constitute actual use of the EESU trademark in commerce?  Read this.  Or did EEStor actually ship test units once upon a time?

What's intriguing about the quotes is some of the listed battery specs.  The charge times listed aren't the 5 minute charge we've grown accustomed to hearing. Instead the various battery sizes include charge times measured in hours....up to 12.
