"the patents were granted in China, but are valid worldwide"

That situation, as (too-) summarily described, does not exist in Law:

* EITHER correspondings patents were granted in all jurisdictions the world over (so, for each Chinese patent, a corresponding US, European, Australian, etc. patent - you get the gist);

* OR patents were only granted in China, and therefore are not 'valid worldwide' (they are only valid in China).

Moreover, a "valid" patent supposes that its subject-matter is provably demonstrated as new and inventive. It's a big call to claim a patent to be "valid", without it being battle-tested (by a Court, rather than a Patent Examiner).

(that's not taking anything from the Chinese Patent Office, though: in my experience, Chinese Examiners are tough, much more so than US and GB Examiners).

I would welcome further clarification, or a suitable rectification by The Reg.
