alt Hacker NewsFor aerospace it's more like asking if Google, Meta, and Apple are encumbered by patents, because they're all big players. The smaller players tend to do one hyper-specific thing for a big player.
Also for aerospace the patents are more legitimate. Software is encumbered by stupid patents <obvious idea> but on a computer! whereas aerospace patents are more legitimately about hardware that indeed took years and millions to develop and optimize.

Something that leaps out at me reading through semiconductor and aerospace patents is a noticeable fraction of them are basically saying, "hey, <non-obvious process understanding that pushes our limits of comprehension of physics required> to achieve some desired effect was found to be useful, but it consumed <years and millions to develop and optimize> because it was such a convoluted journey filled with zillions of dead ends, so we want a patent on that because the end result only looks obvious in hindsight". I don't see as much of this in software at this time, though I suspect it may change in the future.
