SparkFun Hooks a Patent Troll
These kinds of patents really prove that we need to boost the budget for the USPTO since they're always having things like this slip through despite the prior art out there. It's much like the FTC in this situation where Congress knows that if the FTC is well funded then nonsense that businesses do won't get by so easily so they starve the beast just enough to keep it ineffective. I swear it's the same kind of setup for the patent office.
