It takes 20 years for patents to expire, and you can’t commercially use the patented invention until then. If I “invent” and patent 50 different methods to track viewer attention during video advertisements, that’s 50 fewer ways that some company would be able to achieve it.
It would be impossible to cover every possible method to achieve the same thing, but the risk of violating a patent held by a highly litigious patent troll might be a good enough deterrent to stop the whole idea from making it to market for a couple decades.
Yes, but after 20 years you’re not at square one, others have free reign to use and abuse your expired patent. Sure, you can tacticize patents in a way where you make a starting patent, then before it’s about to expire “expand” it with a new one in a way which invalidates use of the previous, but I don’t know if that “loophole” is patched and if not, how it looks in real life.
