Ran across this one. Seems to have been granted, but it's ridiculous that the patent office would allow such a thing to be patented as there is nothing new in it.
It's basically a 767-200 with a smaller lower hold. How this is different than what was already built and/or marketed by other people is hard to understand, and considering the patent claims that "variations" are protected, why isn't this just considered a variation of the 767-200?
Maybe I'm missing what is so unique about this concept that it should be granted a patent in the 21st century. It's interesting it comes out of Seattle. I wonder if the patent holder works/worked for Boeing?
Anyone else know of less than innovative patents granted in aviation?
