Patent Troll Wi-LAN Sues RIM Over Bluetooth & SYM Key Patents


You have to love patent trolls. Wi-LAN is a well known one that specifically buys up patents to sue companies with until they agree to licensing it. According to Wi-LAN RIM infringes on one of their patents for Bluetooth data transmission and another for the “SYM” key (Symbol key) on newer BlackBerry keyboard devices. Seriously Wi-LAN has a patent on hitting a key and selecting symbols from a list of available symbols.

Check out the two patents for yourself at the USPO:

  • Patent 5,515,369 Method for frequency sharing and frequency punchout in frequency hopping communications network
  • Patent 6,232,969 Device for composing or editing a string of characters

As you probably know I am not a big fan of software patents but only time will tell how this one will go. Oh and the best part is that the reason Wi-LAN, a Canadian company, is suing RIM in Florida is because RIM has their BlackBerry World conference there for the last six years. Better yet Wi-LAN just opened up their Florida office last week… via FinancialPost

Here is Wi-LAN’s press release about the lawsuit:

  1. A device for composing a string of characters? Are you kidding me?

  2. The problem with wiLan was they could compete and went out of business selling wireless hardware and then started licensing their crappy patents and suing everyone.
