Personally I read Leahy-Smith America Invents Act in completely opposed way.<p>The old system was only used in U.S. and Canada. Which is pretty shitty thing for any patent system. Global coverage is beneficial on it&#x27;s own right, both for inventors and for economies.<p>Your old system was very susceptible for forgery, produced nasty arguments and rewarded inventors who didn&#x27;t disclose their inventions as soon as possible. All of these are detrimental for both, inventors and economy.
