To file an EU design patent application we do not need a signed Power of Attorney or authorization. However, we need the full name, address, postal code of the applicant. We also need the general name / type of the product and photos or drawings or rendered images of the product. The best way to present an EU design patent is to have a picture or drawing from all sides plus one from perspective. This means, generally we use seven pictures or drawings. Additional images may be filed.
