Sure, go for the patent.

The problem is litigating the twenty or so patents any large company can pull out of the bag, which, if you squint at the blurry lines, might overlap with what you are working on.

Basically, yes, having a patent yourself would be a great help, but it doesn't solve the problem when people are getting patents on what amounts to standard practice.

Yea, in this case I am suggesting that he shouldn't go file for a patent himself. It is expensive, a distraction, and offers no meaningful protection against deep-pockets.
