content: Pre-registration patent validity check. Currently, you just need to put a description of your patent to be registered. There are no a priori verifications on the existence or the innovative aspect of a patent registration request. The only time it's question is when it's subject to litigation ( a posteriori). But this would require a shift from bureaucratic offices to scientific labs, which implies more resources, more expenditure, and a slower (but safer, or more honest) registration procedure. At this point, most uspto (or other registration offices in other countries) are clueless about technical aspects of patents.
