Engineer.AI Global Limited v Appy Pie Ltd & Anor

19 June 2024
[2024] EWHC 1430 (IPEC)
High Court
Two app-building companies fought over the word "Builder." The judge decided the word was too common and descriptive to be a protected trademark for one company, so the lawsuit was dismissed.

Key Facts

  • Engineer.ai Global Limited (Claimant) sued Appy Pie Ltd and Appy Pie LLP (Defendants) for trade mark infringement.
  • The dispute centered on the Defendants' use of "Builder" in their no-code app development products and services.
  • The Claimant owned seven UK-registered trade marks containing "Builder."
  • The Claimant alleged infringement under sections 10(2)(b), 10(3), and 10(1) of the Trade Marks Act 1994.
  • The Defendants counterclaimed that the Claimant's marks were invalid.
  • The trial was split into liability and quantum phases.

Legal Principles

To establish a family of marks, earlier marks must reproduce the same distinctive element with additions, or repeat a prefix/suffix from an original mark.
