Is it sufficient to change only one element to avoid infringement of a registered design?

PROTECTION OF THE OVERALL IMPRESSION

No. The registration of a design grants the right holder protection against any design that, for an informed user, produces an overall impression similar to the registered design, as provided for in Article 41 of the Italian Industrial Property Code.

The assessment of infringement requires a complex and detailed analysis to determine whether the infringing design gives the same impression as the registered design, and whether there is still infringement even if the registered design is partially different from the infringing design.
