In Reply to: Public use of a non-disclosed invention as prior art. posted by Kyle Radek on January 05, 2000 at 07:44:36:

: It is my understanding that selling a product made by an invention is deemed to be a "public use" of the invention and therefore would be considered prior art against a patent application for the same invention (regardless of who applies)if the product was sold at least one year prior to the patent application (under Title 35, Section 102 b, USC).

: Questions:
: 1. Is this an accurate interpretation of the code?
: 2. Must the inventor be the one making / selling product using the invention to be considered a "public use" of the invention?
: 3. What if the inventor assigns patent rights to the company he/she works for and the company sells product using the invention? Is this still considered "public use"?
: 4. Can an invention developed and used by a company as a trade secret to make product which is sold for more than 1 year be patented by someone else, preventing the company from using their own trade secret?
There was a shrimp stripping machine, that was secret. Shrimp were stripped and sold. More than one year after the sale of the shrimp a patent application was filed. The patent was found invalid for public use.
