What is a patent and what you want to know

Martin asked me to put 2 cents in. First, the definition here is from Wikopedia. NOT. It should be from the WPO or USPTO. This highlights the problem of relying on Wikopedia as anything but a starting point.There are precise legal defintions and this aint one so it heads off in the wrong direction, for example by saying "or industrially useful." Huh? Never learned that one in law school. Very misleading. Something can be industrially useful and not patentable. Second, on Martin's search structure claims are missing and all that counts in a patent is the claims. The rest is boilerplate or a way to find it via a unique identifier, (e.g. number). After claims, I would include class as that is the bundle against which a patent is evaluated. Put in a different class and it may not seem as novel or more so. Martin has that in there. Finally, be clear are you doing US only or global.
