Are you sure you are properly managing your trademarks?
The administrative management for a trademark portfolio is particularly delicate.
With increasingly complex regulations, Filing Offices are issuing more notifications of irregularities that need to be responded to with care, rigor and with your interests in mind, in order to avoid rejection or cancellation.
Laws, which differ from one country to another, impose complex administrative formalities as well as compliance with many deadlines, the payment of taxes and other obligations. Failure to comply can result in the loss of your rights, and generate substantial extra costs.
In ten years, the use of your trademark may have changes; your logo may have for example been modified or you have abandoned product or service classes. This needs to be taken into account when renewing.
The ownership of rights may also have changed. And not taking a transfer, merger or a name change into account at the time of renewal can result in serious legal consequences as to the validity or opposability of your tradename.
