After reading a lot of the comments, the suit itself and looking at the products, I don't think Interlink has a leg to stand on, if for nothing else than how the Wii-more works versus how their computer pointing device works.
In case any of you are wondering the interlink device is a commonly used wireless mouse that communicates with the PC via an Infrared Receiver. Since the the Wii-mote doesn't even use an IR receiver but a small camera, and the sensor bar transmits no data whatsoever, I don't know where they can really claim even at the basest level that Nintendo infringe on the their patents. Not to mention that the device Interlink makes is a PC device, and is essentially a mouse, and the Wii-mote only works on the Wii, and has many other functional things going on that has nothing to do with it as a pointing device.
Here's some better explanation: http://jointstrikeweasel.blogspot.com/2006/12/how-to-quick-and-dirty-patent-analysis.html
I was reading some of what the joint strike weasel guy posted, and he says one of the basic claims is that the invention is held like a remote, has a trigger and essentially a button that can be pushed on the top. That is the first claim of the patent infringement. It will be interesting to see how Nintendo responds.
And in a joking tone;
Also, hasn't Interlink done it's homework? You don't sue Nintendo and win, this is the crazy ass company that covers it's butt ten ways to tuesday legally, and even has lawyers shut down Pokemon fan sites....
