Are Asadollah cartouches/signatures found on Ottoman blades? Or only Persian blades?

Thanks for the clarification, I’ve seen it mentioned by collectors that Ottomans and Indians imitated asadullah cartouches on blades they forged themselves, should this be discounted as fiction? I know at least Afghans imitated these marking on Afghan blades, but I was wondering if this was also practiced among Ottomans and Indians.
