As the saying goes, every time an iPhone is dropped, another wide sweeping patent lawsuit in the tech world sprouts up in the plaintiff-friendly US District courts of east Texas. Okay, so perhaps there's no factual basis for that, but who knows if the latest case filed by suit-happy Canadian wireless company WiLAN against Comcast, Time Warner, and Charter Communications is any more legitimate. The dispute is over US patent No. 5,661,602, which is one of the company's 970 issued or pending patents, and was awarded in 1998. It covers "hybrid multichannel data transmission systems utilizing a broadcast medium" -- a.k.a. the broadcasting of data to remote networks and computers. WiLAN has tapped their ole' favorite US law firm, McKool Smith for the case, and asserts that the big cable triumvirate is in violation of the patent, though a spokesperson for Comcast did note they had not been served with a complaint just yet. Sadly (or not-so-sadly, depending on perspective) we can't take part in the gavel swinging, but considering that WiLAN filed suit against Alcatel-Lucent, Sony Ericsson and LG last month, and sued Acer, Apple, Dell, HP, and Lenovo in April, there's plenty of evidence that this outfit's lawyers are the hardest working employees on the payroll.
