This post could be of some intrest to this group of thinking nut cases. 4 years ago I submitted an idea for a smoke detector to my emloyer, (anything I think of belongs to them) and it only took 4 years to get a patent on it with some of the best patent lawyers in the world working on it. I honestly don't see how any individual could get or afford one now days. Just a little off topic, feel free to delete the post, but it is an observation about inventing things these days and just how tough it really is. patent number 7456961
