  • How much does it cost to use “proprietary” TM?

    For many international companies, it is a common practice to allow the use of their trademarks (TM) to all group companies on a free of charge basis. Some parent companies do not even have a right to charge the royalty payments from their subsidiaries, as this contradicts the company’s policy. In the case of subsidiaries located in the territory of Ukraine, such a situation suits everyone, at first glance, because royalties do not have to be paid at all.

  • Business in Ukraine: the ins and outs of top managers dismissal in Ukraine

    Top managers belong to the category of employees on whom the company efficiency depends, as top managers implement business and corporate policies – strategies, business plans, and projects – and make decisions that will determine the future of company business. Although it is indisputable that business is based on complete trust, effective control mechanisms could hardly be dispensed with. These truisms are well known to everyone. However, as practice shows, sometimes business owners overlook important issues that later lead to financial and reputational risks.
