You are correct. Under Purpose column, it says Validity. Since the Validity is no longer an issue, our side may not be able to show it to juries.

"In the years since Sh-Boom’s invention, the speed of processors had by far surpassed that of motherboards, and so practically every maker of computers and consumer electronics wound up using a solution just like the one Fish and Moore had patented." After seeing this part again from the layman's point, I'm kind of lost.
