Sampling Cotton by mechanical unit

Objective:

To identify prior-art before the year 1996 that invalidates the subject patent. There were multiple claim limitations specifying to the design of sampling machine.

Problem:

There were about 100 citations and already known arts that we need to bypass to achieve the prior-art. We performed multiple strategies and were not been able to identify any patent prior-art.

Achievement:

We shifted our focus to non-patent literature to countries with maximum usage of cotton and sampling machines. From, there by applying all strategies using our vast experience we were able to identify one non-patent literature that proved the ultimate prior-art to invalidate the subject patent.
