Trademark application

Trademarks and logos for products and services are registered by means of an application for example at the German Patent and Trademark Office (DPMA). A trademark application consists of a sign (verbal sign, figurative sign or combination) and a list of goods/services, which shall be advertised and distributed with the trademark. After successful examination of the trademark application by a trademark examiner of the office, the trademark is registered and published.

If there are any objections against registration by the examiner they are forwarded to the applicant (or his patent attorney). To these objections one may respond appropriately. After publication of the trademark, third parties may file an opposition, if there are any reasons against the registration of this trademark.
