    Good things come to those who wait? Finally, the main implementing regulation for the Austrian Law on Network and Information System Security ( Netz- und Informationssystemsicherheitsgesetz , " NISG ") was published last week. It serves primarily to define which companies are actually affected by the NISG. Now it is getting serious for the operators of " essential services ". What does that mean?

    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 .

  • Consent or pay – a valid scheme under the GDPR?

    Media companies throughout Europe struggle with a difficult economic environment: Shrinking sales figures for print products, the digitalisation and consumer demand force publishers to offer their content also on the internet. However, generating money for online publications is not quite easy as – at least in Austria – online subscription against renumeration has not been well accepted by customers. This partially has its root in the lack of suitable micropayment means in the past and users thus getting acquainted to online information being offered for free. Thus, publishers have instead focused on financing their platforms by online marketing activities such as placement of banners. Nowadays such digital advertisement is usually targeted to the specific user. For this purpose, cookies are stored on the user's computer upon his first visit of the website, which then collect data about his location, technical equipment used and online behaviour. This finally allows to display specific, user targeted advertisements. However, such cookies may cause issues with applicable consent requirements under the telecommunication and data protection regulations:
