Sure, but at the risk of repeating myself - the existence of the patent application doesn't mean anything other than if some person or company does decide - at some unspecified point in the future - to build an aircraft which uses the technology specified in the patent, they'll have to pay Airbus for the privilege of doing so. It's a technology market thing, not an aviation thing.
