The Cantilever Chair: A Legal History of Design Authorship
A detailed legal analysis traces the authorship disputes over the cantilever chair, focusing on Mart Stam's 1926 prototype and the subsequent 1932 Reichsgericht decision that recognized his artistic copyright. The chair, known as the S32 or Cesca in Knoll's lineage, is commonly attributed to Marcel Breuer, but German courts have consistently upheld Stam's formal matrix. The case became a landmark for design copyright, distinguishing between functional necessity and artistic expression. Anton Lorenz, an entrepreneur, acquired rights and sued Thonet, leading to the 1932 ruling. Later decisions in 1961, 1981, 2009, and 2017 by German courts reaffirmed Stam's protection, emphasizing that the specific cubic configuration of the tubular steel frame is protectable. The article discusses how this history informs Italian copyright law (Art. 2, n. 10) and the broader challenge of protecting industrial design. The cantilever chair remains a typology, but its original form is legally recognized as a work of applied art.
Key facts
- Mart Stam created the first cantilever chair prototype in 1926 using gas pipes and hydraulic fittings.
- The Reichsgericht in Leipzig ruled on June 1, 1932, recognizing Stam's artistic authorship of the cantilever chair's cubic configuration.
- Marcel Breuer designed the S32 model, later known as the Cesca chair, combining chrome steel, wood, and Vienna straw.
- Anton Lorenz acquired rights to Stam's design and sued Thonet, eventually transferring those rights to Thonet after winning.
- The Bundesgerichtshof in 1961 (Stahlrohrstuhl I) ruled that protectability must be assessed at the time of creation, not later market diffusion.
- In 1981 (Stahlrohrstuhl II), the court confirmed Stam's protection and defined the protected elements: continuous tubular line, cubic construction, and severity.
- In 2009, the Oberlandesgericht Düsseldorf banned an Italian company from distributing a replica of Stam's Freischwinger at IMM Cologne.
- In 2017, the Bundesgerichtshof ruled on a case involving prototypes at ORGATEC, excluding distribution rights violation but reaffirming Stam's work as protected applied art.
