Supreme Court rules personal bag reforming does not infringe trademarks

The Supreme Court ruled that reworking branded luxury bags for personal use does not constitute trademark infringement, provided the modified items do not enter the commercial market.

In a case brought by Louis Vuitton against a bag repair specialist, the high court determined that displaying a registered trademark on a reformed product is not considered "use of a trademark" under the Trademark Act if the item remains for private consumption. The court reasoned that trademark law aims to protect business credibility and consumer interests within the trading market, which are not implicated when goods stay in the private sphere.

The dispute centered on a craftsman who disassembled used Louis Vuitton bags provided by customers to create new wallets and handbags. Lower courts had previously ordered the artisan to stop the practice and pay 15 million won in damages. The Supreme Court overturned these rulings in its February 26 decision, stating that owners have the freedom to alter or dispose of their property as long as the results are not sold.

Justices noted that restricting such activities would undermine property rights and the environmental benefits of recycling and upcycling. They added that since reforming often requires specialized skills, allowing owners to hire third parties for these services is a necessary extension of their right to modify their own possessions.

However, the court outlined specific exceptions where liability could still arise. Infringement may be found if a reformer effectively dominates the process to produce and sell items as their own products, or if they knowingly assist an owner who intends to circulate the modified goods commercially. Factors such as who decides the final form of the product, the source of materials, and the nature of the payment will determine whether a specific case crosses into illegal territory.

The burden of proving these exceptional circumstances lies with the trademark holder.
