Crittall reinforces trademark protection following legal ruling

Latest News Thu, Sep 17, 2026 8:56 AM

Crittall Windows is reinforcing the importance of protecting its iconic steel window and door brand following a UK Intellectual Property Office ruling that declared a similar trademark invalid.

The UKIPO decision reflects Crittall's long-standing commitment to safeguarding a name that has become synonymous with authentic steel windows and doors. Built over more than 175 years, the Crittall brand is recognised for British manufacturing, quality and enduring design.

Following a challenge by the Essex-based firm, the tribunal concluded that a Crittall Style Doors trademark was likely to create confusion with the existing Crittall trademark and had been registered in bad faith. The trademark has been declared invalid and Crittall was awarded costs.

Russell Ager, Managing Director of Crittall Windows, said: "The Crittall name represents more than 175 years of British manufacturing and innovation. Protecting our trademark helps ensure architects, specifiers, homeowners and trade customers can continue to identify genuine Crittall products with confidence."

The Crittall trademark was registered in 1928 to protect the company’s name and reputation. Today, it ensures that the Crittall name is reserved exclusively for windows manufactured by the firm, giving customers confidence in the quality and authenticity of every product.

By protecting its trademark, Crittall is helping to distinguish genuine products from those marketed using similar branding, preserving the integrity of one of Britain's best-known names in steel windows and doors.
