The key idea is how long industrial design protection can last with renewals. Industrial designs are typically protected for an initial five-year term and can be extended by renewals in five-year blocks. The maximum duration comes from two renewals that are consecutive, giving a total of fifteen years of protection. Keeping the renewals consecutive ensures continuous protection without gaps, which is important because any lapse could affect enforceability and maintenance of the rights. The other options don’t provide the full, uninterrupted term: no renewal ends protection after five years; one renewal only extends to ten years; renewing twice without guaranteeing consecutiveness could imply gaps or different rules in practice. Thus, two consecutive renewals for five-year periods best fits how industrial design protection is commonly structured.
