Susan M. Hutton - Stikeman Elliott LLP

Within: Competition and antitrust

Top-tier competition shop’, Stikeman Elliott LLP is ‘head and shoulders above the rest’, according to some. Highlighted as ‘extremely strong on the litigation side’, due in no small part to ‘first-class competition litigator’ Katherine L. Kay, the group also excels in major merger reviews, complex behavioural matters and foreign investment work. High-profile department head Paul Collins is a ‘sophisticated operator’ and acted with Ottawa’s Susan M. Hutton to advise Bayer on its headline $66bn acquisition of Monsanto. In another transactional file, Collins is advising Airbus on its partnership with Bombardier and Investissement Québec for the C Series aircraft program. On the investigations front, the ‘increasingly prominent’ Eliot Kolers is representing Sobeys in the Bureau’s investigation into alleged price-fixing in the bread market. In a headline contentious case, star litigator Kay is representing CIBC in a set of class actions brought against several banks and credit card companies alleging anti-competitive conduct in the setting of interchange fees. Michael Kilby, who advised Cheung Kong Property Holdings on its C$2.8bn acquisition of Canadian Reliance Home Comfort, is also recommended. Named partners are based in Toronto unless otherwise stated.

  • Security Token Offerings in the Cayman Islands

    Security Token Offerings (“STOs”) are an extremely popular means of fundraising for new projects and utilise blockchain technology to do so. Whilst no specific legislation has been passed by the Cayman Islands Government in connection with STOs and cryptocurrencies, it would be incorrect to say that STOs are “unregulated”.

    Black Friday is unquestionable one of the most profitable and busiest days of the year for retail, particularly online. Worldwide almost all online store do offer sales or special promotions on Black Friday or Cyber Monday. Already after this practice has established online, a trademark for " BLACK FRIDAY " was registered in Germany back in 2013. In 2016 a Chinese company acquired the trademark and then filed in 2017 for its extension to Austria. Based on the registered trademark, it granted exclusive rights to an Austrian company, which licensed usage rights to various partner stores against remuneration. Further, an exclusive " Black Friday-Cooperation Program " was established. Non-partners who used the event name or trademark were prosecuted and requested to either pay a license fee or refrain from running Black Friday promotions. Some followed the request and entered into license agreements. Some, however, did challenge the validity of the trademark. Finally, respective proceedings to check the actual protection of the trademark were initiated. Austrian courts now held that the trademark " BLACK FRIDAY " is not protected in Austria .

    The role of the news media as the "eyes and ears" of the public, and the corresponding right of such news media to be exempted from the Privacy Act 1993 ( Privacy Act ), is entrenched and well accepted. However, the extent to which the news media exemption applies to non-traditional forms of "news" published by "civilian journalists", such as online commentary and blogs, is a hotly debated subject.
