"Standards are agreed ways of doing something, written down as a set of precise criteria so they can be used as rules, guidelines or definitions." (BSI)
"A patent is an exclusive right granted for an invention, which is a product or a process that provides, in general, a new way of doing something, or offers a new technical solution to a problem." (World Intellectual Property Organization)
If you're having problems finding the standard or patent you need, please email me. We can also sometimes access standards that are outside our subscription to British Standards Online, for example buying a paper copy for the library.
