Patently stupid

I think you missed what bronson is referring to -- he means that a potential acquirer will find out about patents a large company holds and might use to attack them if they acquire you (or your own company if they don't.) khim had asserted that they would never find out, which unfortunately isn't true. In the event they do learn of such a patent, they are likely to pay substantially less for the company.

You're right that patents held by the company to be acquired are unlikely to reduce its purchase price, and can augment it.
