72The comparison of the overall impressions produced by the designs at issue must be synthetic and may not be limited to an analytic comparison of a list of similarities and differences. That comparison must take as a basis the characteristics disclosed in the contested design and must relate solely to the protected characteristics, without taking account of the characteristics excluded from the protection. The comparison must relate to the designs, in principle, as registered, and the invalidity applicant cannot be required to produce a graphic representation of the design relied on, comparable to the representation in the application for registration of the contested design (see judgment of 13 June 2019, Door hanger for vehicles, T‑74/18, EU:T:2019:417, paragraph 84 and the case-law cited).
