How is it contributing to society by harassing people that make stuff while you make nothing?
I get the distinct feeling that the posters yapping about "having to make something with the patent" have never invented or patented anything.
LISTEN UP, ALL OF YOU WHO THINK YOU SHOULD NEED A PRODUCT TO OWN A PATENT:
Let's say that YOU invent a new way of saving battery power in a smartphone. You patent it. But you cannot afford the millions of dollars it would take for you to build and sell a smartphone yourself.
So what do you do? Well, duh, you sell or license your invention to anyone who wants to use it in their product. Or if you're really not into spending your life tracking down clients and selling to them, you sell or license your invention to a patent holding company which has the resources to do the marketing for you. (This is pretty much what universities do internally.)
Licensing your invention to anyone who wants it, is contributing to society. NOT LICENSING IT would NOT be contributing. And of course companies are free to NOT use your patent if they don't want to.
So there's nothing wrong with not making a product yourself. This is AMERICA AT ITS BEST, letting even the small guy make a living from his inventive labors.
WHAT APPLE DID WITH VIRNETX:
Later you discover that a major company is using your method without paying for a license from you. So you offer them a license. But they instead call in their lawyers who do the usual claims that it's not a valid patent, and even if it is, it's not worth what you want for it.
Problem 1: Apple itself had tried to patent at least one of the methods, but found that they could not because Virnetx already had a patent. One of their engineers even admitted it, before Apple's lawyers tried to withhold his testimony. Ooops! Proof of willful infringement of a method that even Apple had thought was patentable.
Problem 2: Apple then claimed that it would cost them too much to switch to a different method. Ooops again. Proof that the patent really was worth money after all.
UPSHOT:
Folks, someone who licenses a patent freely to anyone for a fee is not evil. They're making a legitimate living and offering their invention to those who want to enhance their products. It might even be you, if you're creative.
Unfortunately big companies can use legions of lawyers to try to get around paying you. Sometimes that works, sometimes it doesn't.
