A company called "Immersion" holds a patent that allows them to claim royalties for things that vibrate or provide force-feedback. They're the reason that Sony's Playstation 3 controllers had no rumble features at first — it took losing an $82 million lawsuit before Sony capitulated.
But you know what else vibrates? Things you put inside yourself for sexual pleasure. (Including my personal all-natural pleasure generator: a jar of bees. Just be sure to keep the lid on tight or it won't just be a colony that's collapsing.)
Immersion didn't want to enforce its patents on teledildonic gaming devices — the name is also the cleaning instructions! — so they licensed the rights to the blandly named "Internet Services, LLC", who is in turn suing some other people and then the lawyer left so they sued him and oh I appear to be falling asleep.
Point is, the very same company who makes money for people putting pager motors in videogame controllers also will get money every time you use a USB pocket pleasurer or a commercial interactive deep core drilling simulation. Or would in theory, provided anyone actually used teledildonics for anything more than fodder for tittering.
