In French, the noun protégé has aigu accents over both e‘s. In English, some writers and publishers preserve the French accents, but English is not kind to these marks. They are often omitted in informal writing, and they are increasingly omitted in edited writing. Unlike résumé, which when unaccented can be confused with the verb resume, protégé does not have an unaccented homograph with which it may be confused, so dropping the accents does not create ambiguity.
