EStar Online Trading Limited v Estar Ltd

EStar Online Trading Limited (the applicant) sought to restrain Estar Ltd (the respondent) from using the name "Estar" in relation to its business. The applicant, which operated an online trading platform under the name "Estar," alleged that the respondent's use of the same name for its similar business constituted a breach of trademark law and passing off. The matter came before the Federal Court of Australia.

The central legal issues before the Court were whether the respondent's use of the name "Estar" infringed the applicant's registered trademarks, and whether such use amounted to passing off at common law. Specifically, the Court had to determine if there was a likelihood of deception or confusion among consumers given the similarity of the names and the nature of the businesses.

The Court considered the principles of trademark infringement and passing off, focusing on the likelihood of confusion. It analysed the scope of the applicant's registered trademarks and the extent of the respondent's activities. The Court found that the businesses operated in a similar field and that the names were identical, leading to a significant risk of consumers mistakenly believing that the respondent's services were associated with, or originated from, the applicant. This confusion was deemed sufficient to establish both trademark infringement and passing off.
