Article 47-3Reproduction by the Owner of a Copy of a Work of Computer Programming; Related Matters
第四十七条の三(プログラムの著作物の複製物の所有者による複製等)
The owner of a copy of a work of computer programming may reproduce that work to the extent that this is found to be necessary in order for the owner to execute the work on a computer by themselves; provided, however, that this does not apply where the provisions of Article 113, paragraph (5) apply to the use that is made of such copies in connection with its execution.
After the owner of a copy referred to in the preceding paragraph (including copies made pursuant to the provisions of that paragraph) ceases to own one of the copies of the work for reasons other than the destruction thereof, the owner may not preserve other copies of the work if the copyright owner has not specifically manifested the intention to permit this.
