=== Partial priority for patent claims ===
The extent to which a partial priority can be acknowledged for a single claim in a patent application or patent -i.e., only for a part of the claim, for which the subject-matter is disclosed in the priority document- is a delicate question.<ref>For a discussion of the question, see for example [http://www.epo.org/law-practice/case-law-appeals/pdf/t100571eu1.pdf Decision T 0571/10 of 3 June 2014 of Board of Appeal 3.3.07 of the European Patent Office.]</ref> Decision [[G 1/15]] of the Enlarged Board of Appeal of the EPO deals specifically with this question.

=== Extension of the priority period in case of official holidays and other "closed" days ===
The Paris Convention for the Protection of Industrial Property of 1883 provides for that, if the last day of the 12-month priority period "is an official holiday, or a day when the Office is not open for the filing of applications in the country where protection is claimed", the priority period is extended "until the first following working day".<ref>[https://wipolex.wipo.int/en/text/288514 Article 4.C.(3) Paris Convention].</ref>
