The Trade Mark Protection Act is based on a liberal concept of trademarks. Basically, all graphically representable signs can be used as trademarks in the legal sense as long as they distinguish a good or service from that of a competitor’s.
A Swiss trademark is protected for 10 years from the date of filing. In other words, protection already begins when you submit the application (application date). However, if you decide to make substantial changes in the application, or decide to expand the scope of protection, this can cause a postponement of the filing date and thus of the protection.
