The Associative Laws say that it doesn't matter how we group the numbers (i.e. which we calculate first) ... ... when we add : (a + b) + c = a + (b + c). ... or when we multiply : (a Ã b) Ã c = a Ã (b Ã c).
To complete the PCT in two months (or less) you will need to average approximately 43.6 mi / 70.2 km per day (this was my longest day on trail).
(Note that if you filed a Provisional Application, your one-year period dates from the filing of the Provisional, not the regular utility patent application). You can then file your PCT application at any time within this one-year priority period, claiming priority from the first US application (provisional or non-provisional). Your PCT application covers all of the PCT member countries - 152 of them as of June 9, 2017. Filing through PCT, instead of directly in the member countries, allows you to delay National Phase filing in these countries up to 30 months from your US filing date (31 months in some). This can be helpful, by providing more information and time to make decisions about where to file patent applications.
