The patent will prevent Airbus from following Boeing and develop a twin isle 2+3+2 seat 737/A320 category aircraft
One of the requirements under US Patent law is that the inventive step is not obvious. Now, unless there are some weasel words in the depths of the patent (I only read the abstract and summary, and skimmed the rest), the idea of making the cabin a bit wider to allow 2+3+2 rather than 3+3 seems hard to defend as a non-obvious solution to a problem.
