A lawyer once told me a patent is only as good as you're willing to enforce it, which is true. I was peripherally involved in some court challenges and they get expensive, quick, even for a large company. There is a huge incentive to settle, or not even challenge. I'm a named inventor on quite a few patents, none of them are worth spit, in part because nobody else would want to infringe them.
Most patents I saw were written poorly, they were unclear or left out ways of getting around them. (The old patents are mostly not like this.) And I've read a lot of patents. I got pretty jaded on the whole idea. The patent attorneys were supposed to run their drafts by me, some did for a while, they didn't like my input with one exception. We worked together pretty well and then he got a different job. One thing several would do is to cut and paste "boilerplate" which usually had nothing at all to do with the invention in the middle of a patent. That was annoying because we had page charges, but I guess it made them look better, or so they thought.
The VP in charge was a very sharp guy, he knew the deal. He got moved up, I suspect they wanted him to take over as CLO at some point.
