Where Does Furniture Become "Art"? The Boundary of Design Protection Raised by the USM Haller Case

Steel panels, chrome round pipes, and spherical joints. USM Haller furniture, seen in offices, homes, galleries, and fashion brand stores, is instantly recognizable for its strong individuality. But is that individuality protected as "art" under copyright? Or is it merely an industrial product born from functional structure?

This question has been at the center of a long-standing dispute between Swiss furniture manufacturer USM and a competitor in Nuremberg, Germany. The issue is not simply about "similar furniture." It concerns whether a modular furniture system, designed to be reconfigurable and long-lasting, can be considered a "work" under copyright law, a matter that affects the entire design industry.

On July 2, 2026, the German Federal Court of Justice, known as BGH, made a significant ruling in this lawsuit. In conclusion, USM did not achieve a complete victory. BGH did not make a final decision that USM Haller is immediately protected by copyright but instead found issues with the Düsseldorf Higher Court's decision that denied copyright protection, remanding the case for further examination. In other words, whether USM Haller can truly be considered a "work of applied art" will be reconsidered by the higher court.

However, the implications of this ruling are substantial. BGH reaffirmed that even utilitarian items like furniture could be subject to copyright protection if they exhibit a certain level of originality and reflect the author's free and creative choices. Furthermore, it considered the European Court of Justice's stance that utilitarian items should not be held to a higher standard than paintings or sculptures. This judgment is likely to impact design furniture, lighting, everyday items, shoes, and interior products where function and beauty are integrated.

USM Haller is a modular furniture system created in the 1960s by architect Fritz Haller and Paul Schärer. It was originally conceived as furniture suitable for USM's new factory and office spaces. Like architecture, it combines components and can be expanded as needed. This rationality is its charm and was also a point of contention in the recent lawsuit.

The defendant's argument was straightforward. Elements like round pipes, spherical joints, and metal panels are derived from functions such as stability, ease of assembly, and expandability, not from free artistic choice. Even if they appear beautiful, it is merely the result of technical and practical constraints.

On the other hand, USM argued that it is not just an assembly of parts but that creativity resides in the overall form, proportions, colors, structure, and visual unity. USM Haller has long been regarded as a design classic, appreciated not only in homes and offices but also in museums and design contexts. In other words, it is a utilitarian item with cultural value.

This conflict is highly symbolic for modern design business. Much of product design is not purely decorative but arises from solving functional problems. Chairs are for sitting, shelves for placing items, and lighting for delivering light. However, if everything is deemed "functional and thus not protectable by copyright," superior designs become easier to imitate. Conversely, recognizing overly broad copyright protection could excessively restrict interchangeable parts, repair, reuse, secondary distribution, and independent manufacturers' creativity.

The cautiousness of the BGH's decision stems from this very reason. The court did not say "beautiful design is protected." Beauty and popularity alone are insufficient. What is necessary is to specifically determine which parts are not technically necessary and reflect the author's free and creative choices. When determining infringement, it is not enough to say "the overall impression is similar"; it must be examined whether the protected creative elements are reproduced in the competing product.

The critical point is whether the elements constituting USM Haller are viewed separately or as a whole system. If you isolate just the pipes, spherical joints, or panels, each may appear as functional components. However, when they are integrated through certain proportions, repetition, colors, joining methods, and visual rhythm, there is a potential for creativity that transcends a mere collection of industrial parts. The value of design often resides in the philosophy of combination rather than individual parts.

The reactions on social media and among expert communities reflected this nuanced issue. On LinkedIn, intellectual property lawyers and design law experts showed strong interest even before the ruling, with posts predicting that USM was unlikely to lose entirely and that the case might be remanded. In the comments, there was a shared view that the originality standard adopted by the Düsseldorf Higher Court might have been too strict, considering the European Court of Justice's judgment. Meanwhile, there were also calm voices suggesting that even if a favorable decision for USM was reached, the final resolution was still far off, as prior design and technical constraints could not be ignored.

On X, media posts reported after the ruling that "BGH remanded the case to Düsseldorf, giving USM a tailwind." Additionally, intellectual property accounts shared that USM Haller furniture could potentially be protected as applied art under copyright law, though the final decision would be left to the higher court's rehearing. The tone of the reactions was more of practical interest among lawyers, designers, and furniture industry stakeholders, rather than emotional uproar from the general public, with a focus on how this might affect future counterfeiting measures and the interchangeable parts business.

In the context of interior and design enthusiasts, USM Haller has been reappreciated in recent years as furniture that stands out on social media. The chrome structure and vivid panel colors look great in both minimal spaces and homes with bold colors. On Instagram and TikTok, it is often featured as vintage or used items, custom configurations, and home office storage. This rising popularity boosts brand value but also increases interest in similar products and interchangeable parts. This is why the trial is seen not just as legal news but connected to the consumption of "masterpiece furniture" in the social media age.

Interestingly, the appeal of USM Haller lies in both its "unchanging" and "modifiable" nature. The basic structure has remained largely unchanged over the years, with compatibility between old and new parts being discussed. At the same time, users can freely change the size, color, storage configuration, and use. This flexibility is why it is valued as sustainable and long-lasting furniture. However, its modularity also makes it easier for third parties to create interchangeable parts. What the brand wants to protect and the market's demand for repair and expansion freedom both originate from the same structure.

The recent ruling is not a magic weapon to eradicate counterfeit products. Rather, the court requires the brand to carefully explain "what is creative." For design companies, it is not enough to say "because it's famous," "because it's expensive," or "because it's been selling for a long time." They need to specifically demonstrate creativity by accumulating the development process, design choices, parts that were free from function, evaluations from experts and the market, and how it is treated in museums.

On the other hand, for the interchangeable parts and repair business, the importance of risk management increases. There can be a legal difference between simply selling replacement parts and assembling a furniture system that closely resembles the appearance of the original. Especially when providing services that allow customers to obtain finished furniture that looks similar to genuine products, careful consideration from the perspectives of copyright and unfair competition will be necessary.

For consumers, this ruling is not irrelevant. The price of masterpiece furniture includes not only material and manufacturing quality but also the design philosophy and brand trust that have been protected over the years. Choosing genuine products is an act of paying for that value. On the other hand, if repair, parts replacement, and secondary distribution are overly restricted, it may contradict the sustainable philosophy of long-term use. Balancing the protection of design and the freedom to continue using it will be a major theme going forward.

For Japanese companies and creators, this case is also instructive. In Japan, how to protect the design of furniture, miscellaneous goods, fashion, and industrial products is always a challenge. Design rights, trademark rights, unfair competition prevention laws, and copyrights each have different scopes of protection. Especially with copyrights, which do not require registration, it seems powerful, but for utilitarian items, distinguishing between "creativity" and "functionality" is difficult. The discussions in Europe provide valuable insights for considering Japan's design protection strategies.

The USM Haller case does not present a simple dichotomy of whether furniture can become art. The important thing is to specifically determine how much free creative judgment exists within utilitarian items. Even if the form follows function, how that function is beautifully and consistently shaped as a philosophy can reflect the creator's personality and choices.

USM Haller has not yet been definitively granted copyright protection. The next stage is the Düsseldorf Higher Court. However, the BGH's decision has at least diminished the view that "furniture is unlikely to be subject to copyright." What will be questioned next is where the creativity in the USM Haller system lies and how it was incorporated into competing products.

Masterpiece furniture is both a tool for living and a culture passed down through generations. Therefore, both excessive monopolization and easy imitation can harm a healthy market. The USM Haller case is prompting a reevaluation of what it means to protect design and how society should treat the value of "usable art."
