  • Security Token Offerings in the Cayman Islands

    Security Token Offerings (‚ÄúSTOs‚ÄĚ) 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 ‚Äúunregulated‚ÄĚ.

    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.
