Wi-Lan really is the patent troll that just keeps on suing. You may recall that the company -- which once was an operating company that totally failed in the market, because it was unable to execute -- has since become one of the nastier patent trolls out there, suing everyone it possibly can. Years back, it claimed that it had patents that covered the basics behind WiFi
. After that, it claimed patents on mobile broadband offerings, like WiMax
. It's also sued over patents on mobile devices
and near-field Bluetooth technology
And it's not stopping there. Its latest move is to sue a bunch of cable firms for violating patents with their cable modems
. Basically, if you offer any kind of networking, expect to have to pay some sort of tax to this company that couldn't hack it in the marketplace. Is that how the patent system was supposed to work?
