D.L. Auld Co. v. Chroma Graphics Corp., 714 F.2d 1144 (1983) Notes
1969-producing samples under new method
1969-1973: Auld's sales staff attempts to market samples
June 12, 1973: critical date
didnt actually sell before date but intended to sell. was "on sale."
auld said those were made by a different laboratory method
this doesnt matter, no major differences between methods anyways
plus this patent is on a method,not a product so cant say it was experimentation on the method.
