BlueBrixx

BlueBrixx is a German building-block toy brand associated with BB Services GmbH, a company registered in Flörsheim am Main. Founded in 2018 by German entrepreneur Klaus Kiunke, the brand developed in the market for construction toys that use bricks compatible with the dimensions and connection system commonly associated with Lego products. Its range combines BlueBrixx-designed sets with products supplied by other construction-brick manufacturers, including CaDa, Cobi, and Xingbao. The brand’s principal distinction is its emphasis on large, detailed, and realistic display models. Rather than concentrating exclusively on simple play patterns or mainstream licensed characters, BlueBrixx has built much of its range around architecture, transport, machinery, railways, historical subjects, and other technically or visually intricate themes. Many products are intended to be assembled and displayed by older children, teenagers, and adult hobbyists. The company has also offered children’s sets, so its customer base is broader than the adult model-building segment alone. BlueBrixx generally presents itself as a lower-priced competitor in the construction-brick market and has often used original designs or collaborations with manufacturers in China. The company has also sold third-party brands, making its retail and distribution activity broader than a single proprietary product line. Its BlueBrixx Specials range is notable for providing building instructions digitally rather than as printed manuals. Some products have been reissued with design or production improvements, allowing established themes to remain in the assortment while being revised over time. Although BlueBrixx has generally avoided licensed entertainment properties, its portfolio has included selected licensed subjects, among them Star Trek, Stargate, and RoboCop, as well as products connected with German vehicle and equipment brands such as Schlingmann and Ziegler. These licenses coexist with the brand’s larger portfolio of original or non-franchise models. Retail expansion became an important part of the brand’s development. The first BlueBrixx store opened in Hagen in mid-2020, followed by outlets in cities including Wildau, Munich, and Nuremberg. Reference material states that the company operated 39 stores in Germany by January 2025. Alongside physical retail, BlueBrixx has maintained a distribution-oriented business that brings together its own sets and products from partner brands. The brand has faced repeated legal disputes with Lego. In 2021, a German court granted Lego an injunction concerning the sale of certain BlueBrixx minifigures. The dispute distinguished between the expired patent protection for the basic brick connection system and Lego’s continuing trademark rights relating to minifigure designs. BlueBrixx appealed, but subsequent court decisions favored Lego on the relevant claims. BlueBrixx later brought proceedings against the European Union Intellectual Property Office, and the General Court of the European Union upheld the earlier position in 2023 while recognizing that Lego-compatible minifigures were not automatically protected in every form. In 2024, Lego filed a further lawsuit alleging infringement of industrial-design and copyright rights. These disputes have made intellectual-property boundaries a significant part of BlueBrixx’s public profile.

BlueBrixx emerged in Germany in 2018, founded by entrepreneur Klaus Kiunke. The brand was developed around construction-brick sets using bricks compatible with the dominant connection format in the building-block market. Its corporate registration has been associated with BB Services GmbH in Flörsheim am Main since 2019. From the beginning, the business combined proprietary BlueBrixx products with distribution of construction sets made by other manufacturers, including CaDa, Cobi, and Xingbao. The company’s assortment developed around detailed models intended largely for display. Architecture, vehicles, railway subjects, machinery, and other technically elaborate themes became central to the range. This approach gave BlueBrixx a recognizable position among hobbyists seeking larger or more realistic models, while the company also maintained children’s products. BlueBrixx has generally favored original designs and has often worked with Chinese manufacturing partners. The brand has also used a lower-price positioning in comparison with Lego, although its range includes products from multiple brands and is not limited to one proprietary system. A notable operational feature is the BlueBrixx Specials line, for which building instructions are supplied digitally. The company has periodically re-released sets with improvements, allowing models to remain available while designs or production details are refined. Although the brand usually avoids licensed products, it has introduced selected licensed ranges connected with Star Trek, Stargate, and RoboCop. It has also offered products associated with German vehicle and equipment manufacturers such as Schlingmann and Ziegler. BlueBrixx expanded from online and distribution activity into physical retail during 2020. Its first store opened in Hagen in mid-2020. Additional stores followed in locations including Wildau, Munich, and Nuremberg. By January 2025, reference material reported 39 BlueBrixx stores in Germany, making the retail network an important part of the brand’s market presence. Legal disputes with Lego have been a recurring feature of BlueBrixx’s history. In 2021, Lego secured an injunction involving certain BlueBrixx minifigures. The legal issues separated the underlying brick-connection technology, whose patent protection had expired, from trademark rights claimed in relation to minifigure forms. BlueBrixx appealed, but courts ruled in Lego’s favor on the relevant matters. BlueBrixx subsequently challenged the position involving the European Union Intellectual Property Office, but the General Court of the European Union upheld the earlier outcome in 2023. The court also indicated that compatible minifigures were not protected universally or without regard to their specific form. In 2024, Lego initiated another lawsuit alleging industrial-design and copyright infringement. These proceedings illustrate the legal constraints faced by construction-brick brands that operate in a market built around compatibility while also producing distinctive figures and models.
