Jim - just an FYI - my understanding is that there is no current disclosure requirements in either the EPO or China. I have about 20-30 cases in each country. EPO requires nothing if you come in out of the PCT - they have the ISR, and same for China.
If that's not true, my associates "have a lot of 'splainin to do!"
Actually, Article 36 of the Chinese patent law does impose a disclosure requirement at the time of requesting substantive examination. Bearing in mind that under Chinese patent practice, a literal interpretation of the law is typically applied, if prior art material to the invention arises after filing a request for substantive examination, it is arguable as to whether you need to then submit the prior art.
There is also a requirement to file known prior art upon specific direction from the Chinese Patent Office, however, this hardly ever happens.
