Mr. Grumpy asked, "what about French Pathé discs? do they have some type of marking on them as well?"
"I knew.. I knew you were gonna ask me that question!"--Bonnie Bonnell in "The Big Idea," (1934).
Any disk that looks like this:

… is vertical cut in the Pathé style (i.e., a vertically cut disc designed to be played with a jewel point, like a sapphire. The Pathé style is a different style of vertical cut from Edison Diamond Discs and vertically cut discs designed to be played with a steel needle). Note that the above style of disc plays from the center out.
Likewise, the paper-labeled discs that succeeded the style above, but which retain the design element of a "banner" or "scroll" beginning at about 7 o'clock and wrapping around the circumference of the label to stop at around 5 o'clock (and showing a red rooster standing on a gold disc, usually) is also vertically cut, but plays from the outside to the center.
I am not a terribly familiar with the label styles of Pathé in France and its far-flung international operations. However, in France at least, the company produced vertically cut and laterally cut issues simultaneously from about 1920 to about 1932, at which point they ceased manufacturing vertically cut discs. I believe these are designated as follows on the labels:
Disque à Aiguille (translates as "needle disc" = laterally cut).
Disque à Safir (translates as "sapphire disc," e.g. to be played with a jewel point stylus = vertically cut in the Pathé style.)
I hope this helps… I wish I were an expert on Pathé's products in their home country and around the world, but I am not. Perhaps someone can chime in with more authority.
Best wishes, Mark
PS, Viva-Tonal beat me to it, but I will post anyway. Also, a correction: Pathé in the USA discontinued producing vertically cut discs in December, 1922, not "circa 1926." You will note that the Actuelle discs (lateral) and their sister Pathé discs (vertical) of 1920-1922 credit "Pathé Frères Phonograph Company" but the subsequent Pathé Actuelle discs (lateral) credit "Pathé Phonograph and Radio Corporation." So that is another way to tell: if your USA-origin disc says "Pathé Actuelle," (no matter how small the type used for the "Actuelle" part of the label name) it is laterally cut. If the disc is credited to the Pathé Phonograph and Radio Corporation, it is laterally cut.
