The copyright to a work whose authorship is attributed to a corporation or other organization subsists for a period of 70 years after the work is made public (or for a period of 70 years after the creation of the work, if the work is not made public within 70 years of its creation).
The provisions of the preceding paragraph do not apply if the individual who is the author of a work whose authorship is attributed to a corporation or other corporate body, makes the work public and uses that individual's true name or the pseudonym by which that individual is commonly known to indicate the name of the author, within the period referred to in the preceding paragraph.
With respect to the duration of copyright for a work whose authorship has been attributed to a corporation or other corporate body pursuant to the provisions of Article 15, paragraph (2), even if such a work does not fall under the category of works provided for in paragraph (1), it is deemed to be attributed to the relevant corporate body, and the provisions of paragraph (1) apply.
