The fashion industry does quite well thank you WITHOUT patents. Check it out. No patents in fashion. The most you can do is copyright a logo and slap that on your product. The rest is open season, and we all are the richer for it.
Patents only make lawyers rich at the expense of the rest of us (the 99%).
There is no meaningful comparison between the fashion industry and high technology. Keep in mind also that the fashion industry aggressively uses copyright, which last time I checked is also not too popular. That's why a lot of designer goods have a logo plastered all over them. If we abolished patents, there would be a short time span where everyone would prosper, but then eventually it would become clear that nobody is doing basic R&D, because it would be stolen by a competitor immediately. Also, I assure you there is no lawyer conspiracy. 99% of lawyers are in the 99%.
