The registration of a trademark is one of the most important steps in the development of a brand. A registered trademark gives its owner the right to be the exclusive user of a given sign in relation to the goods and services for which it has been registered. The trademark owner's monopoly over the brand, provides an advantage over the competition, as well as a powerful tool to counteract imitators and infringers.

If a business needs trademark protection in Bulgaria, this can generally be achieved via registering a Bulgarian trademark, or via registering an European Union trademark (as EU trademarks are also valid in Bulgaria.

Below, we will explore what types of signs can be registered as a trademark in Bulgaria and the EU.

1. Word marks

Word marks are the most widespread type of trademark and are well-known to the general public. They are trademarks, which only consist of text elements. The word mark's owner has the exclusive right over the registered text, regardless of the way it's represented graphically. An example of a word mark would be "SONY".

2. Figurative and combined marks

Figurative marks are also very popular. They are marks which include a graphic element. They can be exclusively figurative, for example the adidas "stripes" 1133232a.jpg, but can also be combined, where the graphic element is used in combination with text, and/or where the text is stylised in a particular way 1133232b.jpg

3. Three-dimensional shapes

These marks can consist of shapes, packaging, or the product itself and its exterior. An example of such a mark would be 1133232c.jpg, registered for perfumes. It has to be noted, that there are some additional legal requirements for shape marks and that the Patent Office may refuse registration in some cases. For example, shapes which are necessary to achieve a technical result cannot be registered.

4. Position marks

Position trademarks protect not just a sign, but also the particular position of the sign on a given product. The use of such marks is well-established in the sports shoe industry. For example, in the mark 1133232d.jpg, the protected element are the "stripes", shown in black, and the shoe is depicted with interrupted lines only as a way to indicate how the trademark is positioned on this type of goods.

5. Pattern marks

Pattern trademarks consist of a set of elements which are repeated regularly. Their use is popular in the fashion industry. For example, this is a pattern mark registered by Burberry 1133232e.jpg. Not all patterns are capable of being protected as trademarks. Patterns which are too simple will likely not be distinctive enough. Similarly, patterns which are too complex and cannot easily be perceived and remembered by consumers, might also not have the required distinctiveness that a sign needs in order to be a trademark.

6. Colour or combination of colour marks

It is possible to protect a colour or combination of colours as a trademark. "Owning" a whole colour is a very powerful level of protection and it is not easily accomplished. Ordinarily, there should be prior use of the colour in relation to the goods and services for which registration is sought, before the Patent Office would grant the registration. An example for a colour mark is 1133232f.jpg - the colour of T-Mobile/Deutsche Telekom.

7. Sound marks

Sound marks can be melodies, depicted in the trademark register with musical notation – for example 1133232g.jpg - the Nokia Ringtone. From relatively recently, digital sound files can also be registered, which allows a greater variety of sounds to be protected – for example sound effects, animal sounds and others.

8. Motion marks

Motion trademarks contain movement or a change in the position of the elements of the trademark. They can be registered as a video file, which should show the exact motion being protected, or as a sequence of images demonstrating the motion – for example 1133232h.jpg.

9. Multimedia marks.

These are marks which include a combination of image (still or in motion) and sound. In order to be registered, an audiovisual file must be submitted to the Patent Office.

10. Hologram marks

Holograms are surfaces which show different images depending on the angle of viewing. They can be registered as a video file, or as a sequence of images which shows the holographic effect. For example, Google has registered the following mark as a hologram: 1133232i.jpg.
