@cstross 100% off-topic, but when I was working in a pharma company back in my home country, people told me how when in 1990, the socialist economic system was switched to capitalism and the government became democratic, there were multiple processes that had to be re-engineered because they were a 100% copy of western patents, and later they had to prove that they don't use that old process anymore in court to be allowed to sell in western countries.
