What is the exact nature of Lodsys's relationship to IV? I have done a lot of research on trolls and IV and I am not aware of any connection at all. Basic assignments aren't enough to claim IV's involvement.
As an aside, the FTC is considering a special investigation "piercing the corporate veil" to ferret out the real entities behind trolling operations. If they do, I look forward to seeing their findings. My hunch is that they won't find the usual suspects behind them, if they find any at all.
Sorry for the late response, very infrequent logger-in:
1. No, we really don't know IV was behind Oasis. I am guessing you assume this because NPR reported IV gets 90% of profits. But note how they did not prove or even outright state there was any controlling interest; they just throw the 90% number out there and imply it, Glen Beck-style. The original inventor also made millions off Oasis, but can you say he was "behind" Oasis too? Unless there's a clear indication of control (which shell companies make very hard to prove) it is just as likely a "share-cropping" operation as a shell company. Something like the FTC probe is needed to prove anything either way.
2. IV has publicly stated at an FTC panel that (paraphrasing) they do not sue under any name than their own. Now, that's not under oath, mind you, but making such statements in front of a government panel holds some weight. However, I do find it a bit odd that Lodsys put that denial on their website and then removed it.
