The one year grace period provided in U.S. patent law for at least the past half century never coincided with foreign patent law. In short, there is, and remains, a lack of a clear foreign grace period. Some countries provide the same one year grace period (prior to the most recent change in September 2011), but for different activities, other than offer for sale or public use. Some countries offer a grace period for offers for sale or public use, but for a shorter time period. Some countries offer no grace period. Keeping up with all the different countries and their differing, or nonexistent, grace periods can be a momentous task---among other things, other countries pass and modify laws the same as our country--so to a certain extent, a moving target aspect exists.
This complexity was somewhat mitigated, but also exacerbated, by the international treaty that provided that filing a foreign patent application within one year of filing a domestic patent application (and claiming priority to the domestic patent application) allowed the foreign application to have the effective date of the domestic patent application, i.e., one year earlier.
The result of that treaty was the creation of two one year bars. The US public use/offer for sale one year bar, and the foreign patent filing claiming prior to the US patent application one year bar. but the foreign patent application may not have the same grace periods that the US patent application enjoyed, so even though the foreign patent application was filed within one year of the US patent application (and claimed priority to it), the foreign application may still be invalid if the inventor engaged in public use or offers for sale within the one year prior to filing the US patent application, even though the US patent application would not be invalid. Confused enough? It's like a bizarre Rube Goldberg machine.
As a general rule, with many exceptions that your patent attorney will have to research, do NOT rely on the existence of any foreign grace period.

This strict grace period was enforced after-the-fact. The inventor was required to swear in a declaration, under penalty of Federal criminal law, that the inventor would disclose all material information to the patent office--public use or offers for sale more than year before filing the application being clear material information.
If the inventor didn't tell the patent office, no one was the wiser--until litigation erupted and the inventor tried to enforce the patent in an infringement suit. Then a well funded defendant with a competent legal team would investigate every nook and cranny, interview friends and relatives, and quite possibly turn up the undisclosed public use or offer for sale. The patent would likely be held invalid, and the inventor might even have to pay the defendant's gargantuan legal fees. Thus were the strictures of the one year grace period enforced.
That was then. The Leahy-Smith America Invents Act signed into law on September 16, 2011 changes all that, as discussed in the following posts.
