Porsche is currently appealing a decision by European trademark authorities regarding a sound designed to replace the near-silence of an electric vehicle accelerating. Porsche had submitted the sound as a trademark, aiming to address the need for electric vehicles to emit identifiable sounds for vision-impaired pedestrians.

However, the European Union Intellectual Property Office (EUIPO) rejected the trademark application, stating that the sound lacked distinctiveness and resembled a traditional internal combustion engine, making it unrecognisable as distinctly Porsche. Porsche appealed this decision, highlighting that the sound was artificially created and not derived from an engine.
