Assumptions: a) You believe in the value of patents and b) you have something that can be patented.
For example, I saw a group of seed investors try to identify potential patents in their portfolio companies as a way to increase the scrap value of the firms in the worst-case scenario. But they weren't making go/no-go decisions on the basis of the patents, it was just a slight value-add after a go.
Patents only seem to be of primary importance in a few niches.
Yeah. We aren't doing that these days.
