It is very unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (such as China, Japan, Korea and many others worldwide). As this work was first published before 1925 or failed to meet notice or renewal requirements to secure statutory copyright with no "restoration" under the GATT amendments, it is very likely to be public domain in the USA as well.

two slightly different editions, 1917 and 1922, appeared during the composer's lifetime; see Medtner.org.uk.
From Prokofiev's diaries, apparently after hearing the composer perform this: "excessively Medtnerish with nothing particularly new in it, but good all the same and I would like to play it myself." ("Sergey Prokofiev diaries, 1915-1923: behind the mask", Page 96.)
First performed 20 February 1915 O.S.? (I believe Martyn uses old style for Russian dates before 1918 by his own notes, so have converted above.)
