It's a brand name for a USB device that provides an RS-232 interface. There is absolutely no way to confuse the two things. If you were searching for the RS-232 device and you happened to know the brand name for this particular one (not sure why you would, exactly), then you could search for "airconsole rs-232" and Google ranks it #1. If you are searching for "usb rs-232", at least for me it doesn't even end up on the first page. If we're talking about trademark infringement, then this is not even close (it's impossible to confuse the two products). If we're talking about being nice: if you had to avoid every single established name of every single minor product in every single country in the world... you would have no names left. All new products would have to make up gibberish names. I appreciate that for some reason this device is "mainstream" in your eyes and should have some extra special protection, but that's not the way international agreements on trademarks work -- for a reason.
