Someone needs to tell these guys that AT&T isn't the only company that sells the iPhone any more! Wow. At least they didn't name Cingular. From what others have stated, I get that they're not patent trolls—BUT pulling in AT&T seems very Trolley McTrollerson.
I had two Verizon touchscreen phones before I got the iPhone and they both had similar Taptic feedback. I wonder why they aren't suing them instead? I guess that's not where the money is.
Verizon and Samsung were the first to put out an entire phone ecosystem using Immersion technology back in 2005 or so.
So it's a pretty good guess that Verizon has a license for the phones they sell.
I have no idea if Immersion has a case or not, or if they are a patent troll or not. But I will say that the fact that other companies have licensed Immersion tech is irrelevant.
Legally, it's very relevant. It means other large corporations either acknowledged the patents, or fought them and lost.
One thing doesn't look good to me though. Immersion is located in San Joe and Apple is located in Cupertino. A logical and convenient location would be to file the lawsuit in California, such as when Apple filed a lawsuit against Samsung. However, Immersion filed the lawsuit in Delaware, a known patent troll haven second only to East Texas.
California juries are well known to favor Apple. And from what I can tell, Immersion is apparently incorporated in Delaware. Which state would you pick if you were Immersion?
Companies who are confident of their patents do like Delaware because the judges are technically experienced, and trials are fair and over fast. Also, IIRC, over 90% of cases are settled out of court beforehand. (Remember Nokia v. Apple?)
