I still don't understand how a company with no actual operations and don't sell anything can be found to be damaged... what a mad world.
I'll caveat this with: I'm not defending patent trolls. I despise them, think they are leeches harming the technology industry and society as a whole, and also think the entire patent system is rather broken and in all likelihood this particular patent shouldn't exist in the first place for any or all of a variety of reasons.
But, you can think of it this way (leaving non-practicing entities out of it): I have a brilliant idea for a widget. I develop the idea to the point that I know how to build the widget and patent it. The widget, however, requires a bunch of manufacturing, marketing, and distribution infrastructure to actually make money off of, which I don't have, so I offer the widget idea up for licensing if anybody else wants to use it to make money.
Company A says "Sure! Here's $100 million for a non-exclusive license to manufacture the widget you developed."
Company B says "Screw you, we're just going to build the widget anyway and not pay you."
In that scenario, it's pretty clear how you were being "damaged" by Company B, although you don't actually make anything yourself. In that scenario, Company A is also getting damaged, since their version of the same widget is going to cost more since they paid the license for it and Company B is flouting the patent and using it for free.
By extension, then, if Company A doesn't exist and Company B does and does the same thing, you have a situation where a company decided to "steal" your idea instead of paying, even though you weren't making anything with it, so there's a pretty clear argument to be made that you've been damaged.
By extension, if Company C says "Well, we don't have any manufacturing ability ourselves, but we're good at licensing to manufacturers, so we'll pay you $150 million for the patent because we think we can get other companies to pay more than that later," then it's totally legit for you to sell your widget plan to them for $50 million, and totally legit for them to expect to be able to license it to Company A and B for $100 million each. If Company A pays and Company B doesn't, you're out $50 million on your speculative venture despite both companies selling the widget that you paid a boatload of money for the rights to.
Since this is (I think?) a
FRAND patent, it's part of a standard so companies are expected to be offered a fair and non-discriminatory licensing fee to use it, but if they don't pay when everybody else did, then they're getting an unfair advantage. In this case something to do with the implementation of LTE, which
in theory other companies using the same technology are paying. Being patent trolls, who knows--it's totally possible that they only sue the big targets in Payday District, Texas, and completely ignore everybody else.
You could also use the analogy for copyright. If I write a book and nobody wants to publish it, I have no actual operations and $0 in sales, I just have a manuscript. But if one of the publishers turns around and publishes it without paying me, then I've been plenty harmed. This one actually does happen.
