Starting in November 2000, the USPTO started publishing patent applications 18 months after their earliest filing date. So the simple assumption is that you file a patent and 18 months later it get publicized, right? However, since the US has moved to a first-to-file System, the “earliest filing date” is really 18 months after the earliest priority date or an application can take advantage of the 12-month grace period could be published as early as 6 months after filing.
