There was also once a suit by a company called USL...Hello Winfield,
But, if as Skybuck stipulated, the invention was secretly contained within
the product, not advertised or discussed by the manufacturer in brochures,
manuals, etc., and not apparent to a product user, or to one studying the
product, it's hard to see how it could be declared a publicly-disclosed
prior art, and used to overturn the new patent. This is one of the reasons
for open disclosure of inventions, or alternately for defensive patenting.
That often doesn't stick in a lawsuit. IIRC there was a company that
made golf balls from Surlyn or some kind of special plastics. They kept
the golf ball innards a secret but sold lots of these which constitutes
"noninforming public use". Then Dunlop engineered something similar,
filed a patent for the technology and subsequently sued. AFAIR Dunlop
lost and their patent was declared invalid because of prior noninforming
public use.
