"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.
