Re: Prior art??
As silly as it may be the Patent office is only there to record and to act as the most basic of filters. The courts decide on the validity of a patent if there is ever a challenge.
That might be how the USPTO sees it (although it shopulnd't!), but the courts take the opposite view: a patent that has been granted by the USPTO is presumed valid, and is not invalidated by the court without a significant amount of work.
This leads us the the disconnected situation we currently have in the US - both the courts and the USPTO believe it is the other's responsibility to decide on the validity of patents, so no-one actually performs the function.
IMO, if the USPTO isn't properly determining whether something is patentable or whether it is covered by prior art, it is nopt doing its job, and is in urgent need of reform. Yeah, like that's going to happen :-(
