  • Sponsored by Patrinos & Kilimiris
    Although there are several and severe restrictions due to COVID-19 in Greece, which inevitably affect trademark practice in relation to both prosecution and litigation, there is some good news in the field. The new law on trademarks has come into force, implementing Directive (EU) 2015/2436.
  • Sponsored by Patrinos & Kilimiris
    The newly-born Greek law on trademarks implementing Directive (EU) 2015/2436 has an attention-worthy provision, relating to the renewal of trademarks within their grace period. More specifically, the new Greek law on trademarks provides that the payment of the renewal fee can be made within the last six months of the protection’s term. It can also be made within an additional term of six months following the expiry of the formal protection’s term, subject to the payment of the renewal fee increased by 50% and without negating third parties’ rights acquired in the meantime.
