You mentioned EOLAS as a patent that I guess you think covers something with no utility. Clearly most people think browser plugins have utility. The problem with the EOLAS patent wasn't that plugins aren't useful. The problem was that they sat on their "rights" for years, then launched a sneak attack. In the landlord-tenant analogy several types of estoppel would have prevented that. You're probably familiar with "squatters rights". In that case, Microsoft was the squatter on EOLAS claimed property. Perhaps they should have had squatters' rights.
You also mention bad patents - companies patenting methods or inventions they didn't invent. That would compare to a false "landowner" demanding rent for land they don't rightfully own.
None of that in any way supports the assertion that patented inventions hold no utility for the user. I'm utilizing patented technology to write this, so clearly Google's R&D had some utility to me, the user.
You could probably make several reasonable arguments about patents - that the patent office should be far more strict about patents they grant, about patent trolls vs. inventors, etc. The problem is, all these arguments are all mixed up in your head, so you don't seem to know which argument you're making at any given time. Your zealotry even seems to have you so confused that you'll believe, and argue, anything that seems vaguely anti-patent. I bet you'd argue that patents are unconstitutional, simply because you'd like them to be. There are plenty of good arguments about patent trolls. Slow down, read them carefully, and THINK about them.
