The reproduction of famous porcelain sculpture designs is governed by a complex web of international copyright laws, which aim to balance artistic protection with cultural exchange. Under frameworks like the Berne Convention, original sculptural works are automatically granted copyright upon creation, typically lasting the creator's lifetime plus 50–70 years. This prevents unauthorized copying but allows limited reproductions for educational or preservation purposes.

However, restrictions vary by jurisdiction. In the EU, "industrial copyright" may protect mass-produced designs for 25 years, while the U.S. requires distinct originality for protection. China’s copyright law enforces strict penalties for replicating cultural heritage pieces, yet antique designs often fall into the public domain.

Key challenges include proving infringement across borders and addressing "derivative work" disputes. While copyright fosters innovation, some argue it stifles traditional craftsmanship. Museums and artists increasingly use licensing to legally share designs, ensuring both protection and accessibility. Understanding these laws is crucial for collectors, artists, and cultural institutions navigating global art markets.
