Understanding the Grace Period for US Patent Foreign Priority

Inventors have a one-year grace period to apply for US patents, starting from the effective priority date of their foreign patent application. This means that if the publication date of the foreign patent application is less than one year old, they can still file a US patent application. However, without a claim of priority to the foreign request, such an applicant could face more technical background that could be invoked against the US request. It's important to note that grace periods don't protect a patent application from independent disclosure by third parties. The Patent and Trademark Office (PTO) will be officially closed for a full day, and for adverse weather or other causes, the Office will consider each of those days as a “federal holiday” in the District of Columbia for those under 35 years of age.

The PTO is not open to the submission of applications within the meaning of Article 4C (of the Paris Convention). Some countries that grant inventor certificates also provide by law that their own nationals employed in state-owned enterprises can only receive inventor certificates and not patents on inventions made in connection with their employment. Patent law gives inventors a grace period of one year during which they can still be eligible for patent protection for a disclosed invention before filing a patent application. This rule, known as the absolute prohibition of novelty, requires that you avoid public disclosure of your invention before filing a patent application if you want to apply for foreign patents. According to § 102 (b) (A) of the AIA, inventors have one year from the time they disclose an invention to file a patent application.

These include the African Regional Intellectual Property Organization (ARIPO), the Eurasian Patent Office (EAPO), the European Patent Office (EPO), the Patent Office of the Gulf Cooperation Council (GCC) and the African Intellectual Property Organization (known by the acronym OAPI by its French name, Organisation Africaine de la Propriété Intellectuelle).These provisions are in no way a substitute for the time requirements contained elsewhere in 37 CFR 1.55 for filing a priority application and for the certified copy of the foreign application. The table indicates whether a priority basis is that the State is a party to the Patent Cooperation Treaty (PCT) or to the Paris Convention for the Protection of Industrial Property (Paris), or is a member of the World Trade Organization (WTO). In other words, you cannot invoke the one-year grace period to delete an article by a competitor as prior technique against an inventor's patent application. For example, if you first publicly disclosed your product or concept at a trade show, you can still file a patent application in the US within 12 months of your first public release. This would occur, for example, when an international application was filed in which the United States was appointed to a foreign receiving office and the applicant filed a continuation of an international application under 35 U.

S. C. § 371(c).The potential dangers of prior public disclosure force us to rethink our strategy when it comes to deliberate public disclosure of an invention before filing a patent application, in order to override any actions taken by third parties in between. If the priority application or certified copy of the foreign application is filed after paying the issuance fee, then unless corrected by a certificate of correction in accordance with 35 U.

§ 255, it won't be included in your patent. In conclusion, inventors should be aware that they have one year from their first public disclosure to file their US patent applications and take advantage of any grace periods available in other countries where they wish to obtain protection.
