Replicating famous bronze sculptures raises significant copyright concerns, as many iconic works remain protected under intellectual property laws. Even after the artist's death, copyright often persists for decades—typically 70 years in most jurisdictions—meaning unauthorized reproductions may infringe on the rights of estates or foundations.

Commercial replication without permission can lead to legal action, including fines or injunctions. However, some sculptures, like ancient Greek or Roman works, may fall into the public domain, allowing limited reproduction. Ethical considerations also arise, as mass-produced copies can dilute the original artist's legacy.

For modern sculptures, licensing agreements or commissions from the copyright holder are essential. Museums and foundries often hold exclusive reproduction rights, requiring formal approvals. Always consult legal experts before replicating any copyrighted artwork to avoid costly disputes.
