[W&B] How Come no Rochester Optical Patents

[David Silver]

Anthony and Blair were people, so any of their patents are pretty obvious.
For Kodak, well, George Eastman WAS Kodak and he kept an iron grip on any
ideas his engineers contrived, so those many patents are also obvious.
Scovill and American are more difficult, but there are common patents
under the company names.  Rochester patents, and there aren't a heck of a
lot of them, are under indiviudal names, Walker, Carlton, whatever, so you
might not see the company connection.  They're there, but yoy have to
connect some dots.  I'm sure some of the folks here who are so good at
patent research can dig out some examples.  Ehrmann, McElroy, any
comments?

Best wishes,
