It may appear simple enough. You make an application for trademark registration using form TM3, which you can download or complete on-line. You are required to provide an illustration of the mark and indicate whether it is a series of marks. If it is a series of marks, then you are limited to six marks in the series. The goods and services you may apply for are divided into 45 classes. This is all set out under the Nice Classification. You just say what goods or services you want the mark to cover. In-fact only a very small percentage of trademark registration applications are challenged. It can cost you as little as £170 for the whole process without a lawyer. It makes sense to do it yourself, and then get a lawyer if the trademark is ever challenged. That simple, right? Well, not always.
