Trademark (known in business circles as a „brand” or „brand name”) is a sign used to identify and distinguish the goods of one manufacturer or seller from those of another and can be presented in the State Register of Marks in such a way that it is possible to clearly and accurately determine the subject of the protection granted with the registration. Such signs may be words, including names of persons; letters; numerals; drawings; figures; the shape of goods or of their packaging; a combination of colors; sound signals or any combination of such signs.

According to the way of representing the marks are three-dimensional, sound marks, combinative, word, figurative. According to their use, marks are trademarks, service marks, collective marks and certification marks. Depending on its territorial validity the mark may be registered as a national trademark, regional (European Union trademark or Community trademark) and international trademark.

The most effective way to avoiding judicial intervention is the provision of effective preventive services. For this reason, the registration and maintenance of trademarks are the main actions, which have to be undertaken by every business. When the trademark is registered the possibility for infringements and losses due to imitation of the protected goods or services is minimized. In this regard, it is advisable to seek an assistance from a specialist with experience in the this field, as a thorough knowledge of trademark law is required and a number of features need to be taken into account. An experienced trademark professional will not only take care of the registration of your trademark, but will also help you successfully retain your trademark after registration, which is one of the most important obligations of any trademark owner.
