Someone in the US patented "Basmati Rice"that has been grown and used for thousands of years in India. It took more than a decade before that patent was nullified. Most patents are nuisance and have no real inventive values.
One of the guys at my store swears that Canon invented light but God beat them to the patent office. E3 was a joint Nikon-Fuji product, no stabilization.
A food company in Japan has Indian "curry"flavor patent in its list of innovations. The highest courts in Japan have upheld their right to that patent as well. It appears that Nikon lost that battle The movie industry has a HUGE dollar burnrate. They tend to develop ways to "get it right" earlier that still photographers. Often the gap is several decades; when "still photographers discover it". The military has been aware of this probaly since WW1 and the biplane. For movies; Dynasciences Zcorp in has the Dynalens; with a fluid lens with a servo that quashed image motion.
The US patent number is 3,, See patent 3,,, and 3,, too. Alright, you got me. I confess: it was me. You are all wrong. It was Pres. George Bush for all of them.
