Israel Patent Application Number 227201 was timely filed. The problem was that the PCT application PCT/CA2012/000007 from which it was derived was filed late. The PCT should have been filed on 30 December 2011 but was actually filed on 4th January 2012.
The applicant of the PCT successfully persuaded the Canada Patent Office, acting as the PCT receiving office, to recognize the application as timely filed and to recognize priority of the PCT from various US provisionals: USSN 61/428,435, USSN 61/428,676 and USSN 61/428,445. This occurs under Regulation 26bis.3: Restoration of Right of Priority by Receiving Office.
Nevertheless, on entering national phase into Israel, the applicant should have petitioned to have the priorities recognized within one month. Applicant failed to do so and requested priority to be recognized in the second month from filing the national stage application.
The PCT Division of the Israel Patent Office refused to recognize priority. Applicant appealed to the Commissioner who granted leeway and referred the case back to the PCT receiving office to check that there were no other problems.
There are various reasons by which the Paris Convention deadline for filing a PCT application may be extended. Postal strikes and patent office closures are good examples. Sometimes inclement weather is allowed, but it has to be really bad.
