Obi loses "Orange" trademark battle against Hornbach and Globus
On September 17, 2026, the German Federal Court of Justice (BGH) ruled that hardware chain Obi cannot protect its specific shade of orange as a trademark. The court determined that the color lacks "distinctive character" and serves only as a general reference to hardware stores, ending a years-long legal dispute. This decision allows competitors like Hornbach and Globus to continue using similar tones without legal repercussions, reshaping brand identity strategies in the European DIY retail sector.
Construction material costs surge 10% year-over-year
According to data released on September 15, 2026, by Anirban Basu, chief economist at Associated Builders and Contractors, prices for key construction materials including copper, lumber, switchgear, and derivative metal products have increased by more than 10% since August 2025. This inflationary pressure is directly impacting renovation cost indices and squeezing contractor margins, forcing homeowners to re-evaluate project scopes and budgets.
Hornbach acquires six Hellweg locations post-insolvency
In a move consolidating the German DIY market, Hornbach has secured the rights to six former Hellweg hardware store locations following Hellweg's insolvency proceedings. The acquisition, announced around September 18, 2026, is part of a broader redistribution where Hornbach, Obi, and Bauhaus collectively took over 35 of Hellweg’s stores. Hornbach plans to open these new branches in spring 2027, aiming to capture market share lost by the insolvent competitor.

Cainz launches Fall/Winter 2026 product line and urban expansion
Japanese home center chain Cainz unveiled its Fall/Winter 2026 collection on September 16, 2026, focusing on "relaxing interiors" and cost-reduction strategies to combat persistent inflation. The company introduced 84 new products, including system kitchens and gardening soil, developed in cooperation with suppliers to lower costs. Concurrently, Cainz is accelerating its strategy of opening smaller, urban-focused renovation specialty stores, with a new location recently opened in Machida Station, signaling a shift toward accessible, high-frequency DIY and repair services.
Local view
In Germany, the BGH ruling on Obi's orange trademark is being covered extensively by major outlets like Der Spiegel and t-online, which highlight the end of a multi-year legal saga between the country's largest hardware chains. Chip.de reports that Hornbach’s acquisition of Hellweg sites is seen as a strategic opportunity to expand its footprint quickly despite economic headwinds. In Japan, Sankei Shimbun and Diamond Retail highlight Cainz’s pivot toward "compact urban stores" as a response to changing consumer habits, emphasizing convenience and specialized renovation services over big-box bulk buying.
