How Do You Prevent Provisional Patent from Expiring?

One way to prevent the provisional from expiring is to continuously have a provisional one file (just updated to the latest version of your back-end). If you let the provisional expire (and your back-end isn’t receiving a lot of press), you are back to square one. For the provisional to save you the risk of challenging a Patent, you must timely file a non-provisional before the provisional expires.

Having a provisional on file is the best way to go - they were established to level the playing field against large entities To prevail for the patent rights (before anyone else can get a patent to assert over you in the first place), you must be the first-to-file. Having prevailed to the patent rights is a way of saving in legal fees, building a fence around your technology, and growing your intangible asset portfolio.
