I don't claim this failed to occur because Sony is more decent than average, but because the idea is self-evidently very stupid. The thing is, when you get to have a "Patents" section in your CV, no one cares very much that they are stupid patents as long as you were working for a serious company when you got them. There is a point past which that's just a perquisite, like how the company subsidizes your au pair.
I've never needed an au pair! And I hold no patents of which I'm aware. But it is not 2009, or even 2013, any more.
