I recall Xerox was not happy with the use of their name in the generic 
for copiers.  They attempted an ad campaign, but there was nothing they 
could do.  That said, you can't put Styrofoam on your "extruded 
polystyrene" products unless you are Dow... lol

Wow!  I just read wikipedia on this (and some other references) and it 
seems there is a lot more to it.  First, Styrofoam is "extruded 
polystyrene" while styrofoam is not.  The stuff we generically refer to 
as styrofoam is actually "expanded polystyrene" which is slightly 
different.

I was in a styrofoam factory once working on the alarm system.  They 
used small pellets of polystyrene soaked in pentane which were placed in 
a rectangular mold.  On heating the polystyrene softens and the pentane 
turns to a gas expanding the beads.  If there are enough to more than 
fill the mold after expanding they stick together making the stuff we 
put food in.  Extruded polystyrene is not made from the beads, but is 
made of the same stuff that is in the beads.  Dow only sells it for 
thermal insulation and is dyed a light blue as a trademark.  Corning 
dyes their similar product pink and they've trademarked that color!  So 
the color indicates brand rather than material.
