Key legal question
Whether the use of the company name 'AC. AG' constituted unfair competition by creating a likelihood of confusion with 'AB. GmbH'.
Extracted holding
Yes. The newer company name was not sufficiently distinguishable in the relevant market context and created a likelihood of confusion.
Extracted reasoning
The shared initial element and the parties' same location, branch, and customer base made confusion likely from the perspective of the average Swiss public.
