Have to leave to pick up folks at the airport but as a brief note off just the title - my go-to examples/running list for the US possibly quashing innovation has historically been airless tires, but there was another example I'll try and dig up when I get back (maybe someone else can in the meantime) was one circulating about innovative needles for hospitals to prevent accidental injections among healthcare professionals - I believe it was brought up on HN, might sound familiar. If the title-based judgement is unrelated, apologies. If it is not, I'd love to hear more examples of this, been wanting to get a list going for further study.
