Not in the US; in NZ most houses will have a “wash tub” - essentially a sink in a metal cabinet specifically for doing “dirty” jobs like laundry. That will have water hookups for the washer, so that goes next to it where there is space, then the dryer will do next to that or on top of the washer.
The last few places I’ve lived in have all had the tub in a corner with space on its left, so it’s been dryer, washer, tub. Annoying, my dryer door opens to the right and the washer to the left, so it’s harder than it should be to move clothes between them
Unfortunately, the way patent suits work it could be enormously expensive to defend something like this, even when the patent is clearly bad.
You’d be arguing that the patent is invalid to start with, but the court would probably start from the position that you are actually infringing a valid patent (it was granted after all), and grant an injunction to prevent further harm (“stop giving people the software until we can work out if there is any merit to your claim that you aren’t infringing”). You then need to put together a case to show the prior art, and you can bet that they’d contest every single point. This whole process could take years, and cost hundreds of thousands of dollars that you won’t get back even if you win - there isn’t really a provision to recover costs in patent cases because there is the assumption that every claim is made in good faith
