#391 Patents

[Howard Lovatt]

I think the change in US Patent law is to bring it into line with the rest of the world. Previously a US, note US only, company could produce lab notes or similar to give an earlier priority date than the filling date. The change isn't saying you can't use prior art outside of patents to invalidate a patent, it is just saying you can't back date your priority date. At least that is what my works in-house lawyer said the change was.
