SMA Solar Technology AG v Sunny Energy Australia Pty Ltd

This matter concerned an opposition by SMA Solar Technology AG (the Opponent) to the registration of three trade mark applications by Sunny Energy Australia Pty Ltd (the Applicant): application numbers 2071681 (Class 37), 2071692 (Class 37), and 2073806 (Class 35). The Opponent sought to prevent the registration of the marks SUNNY ENERGY AUSTRALIA, SUNNY ENERGY, and SUNNY ENERGY AUSTRALIA on the grounds that they were likely to deceive or cause confusion due to the Opponent's established reputation in Australia under its "Family of SUNNY Marks" for a wide range of solar electricity generation products and services.

The primary legal issue before the Delegate of the Registrar of Trade Marks was whether the Opponent had established a reputation in Australia for its "Family of SUNNY Marks" at the relevant dates, and if so, whether the use of the Applicant's proposed marks would be likely to deceive or cause confusion, pursuant to section 60 of the *Trade Marks Act 1995* (Cth). This required the Delegate to assess both the quantitative and qualitative dimensions of the Opponent's reputation, considering factors such as sales volume, advertising expenditure, promotional activities, and the overall image projected by the marks. The Delegate also had to determine the degree of similarity between the respective trade marks and the connection between the goods and services offered by both parties.

The Delegate found that the Opponent had established a significant reputation in Australia for its "Family of SUNNY Marks" in relation to solar electricity generation, maintenance, monitoring, and regulation. This reputation was supported by substantial sales revenue, extensive promotional activities, and a global presence in the solar energy industry, including a significant market share in PV monitoring systems. The Delegate considered the Applicant's argument that the word "sunny" was non-distinctive but rejected it, finding that "sunny" and "solar" were not synonymous and that the Opponent was not seeking a monopoly over all marks containing "sunny" but rather those similar in format and context to its own family of marks. The Delegate concluded that the Applicant's marks were sufficiently similar to the Opponent's "Family of SUNNY Marks" and that the Applicant's services were the same or closely related to the Opponent's goods and services, leading to a real and tangible likelihood of consumers being caused to wonder whether there was a connection between the parties.

Consequently, the Delegate upheld the opposition under section 60 of the *Trade Marks Act 1995* and refused the registration of the three trade mark applications. The Applicant was ordered to pay the Opponent's costs.
