The amount of time during which the inventor may still file a patent after disclosing the invention. This is 1 year in the US, and 0 in Europe.

Generally patent may not be granted for an invention that has been disclosed before the filing of the patent. In some countries, there is a grace period during which the inventor may still file a patent after disclosing the invention. In particular, in the United States, the inventor may file a patent up to one year after (this is sometimes known as the “one year rule”). The AIA changes the details of the grace period for applications filed on or after March 16, 2013. Most jurisdictions, for example the EU, do not have a grace period at all.
