All of those things were taken well after any reasonable patent would have expired, so I don’t think they are comparable to the ip theft currently being discussed in this thread. I thought the upstream comment was talking about more recent examples.
Did China try to prevent gunpowder or porcelain from being made by outsiders?
- oytis 5y agoThey definitely did try to keep porcelain a secret. As of gunpowder it wasn't stolen by Europeans, rather it seems that it was Mongol invasion that let the knowledge spread.
- onionisafruit 5y agoThanks. I didn’t know anything about porcelain’s origin. I’m adding porcelain’s wikipedia page to my “to-read” list.

"IP" is broader than patents that tend to have an expiry date - but even the expiration periods of patents is determined by the host government and not the appropriator. The US has a lot of classified information that would have long since expired had it been a patent, e.g. 1970's nuclear tech, alloys used in submarines, stealth coating on jets. Porcelain and the other examples gp gave would have fallen under the blanket of "National Security" rather than patents.
