Larry,
As I heard it, R-12 was banned because DOW Chemical's patent had run out
and
they would have had competition. New product R-134a, new patent, no
competition!
Dirty enough to be true.

You been watching to much Fox News. ;-) CFC-12 was invented in 1928 and
the patent is long expired. At least 14 companies around the world have
been producing CFC12 since 1949. DuPont just owns the trade name "Freon".
