Besides registering or buying a trademark outright it is possible to License the rights to the Trademark or IP rights. Generally this is a lower cost solution. The way it works is that in return for a monthly fee you can be granted a license to use the Trademark rights from the owner of the IP. The rights can be exclusive or non exclusive.
Licensing is a great solution for a smaller business as the upfront cost is usually less and it can be much quicker than the time and uncertainty associated with a new registration.
A typical example of a license agreement is here: Licensing Contract
(1) London IP Exchange Limited of One London Wall, London, EC2Y 5EB ("Licensor");
(2) Example Company ("Licensee").
(A) Licensor is the owner of the Trade Mark(s) (as defined below) or has a right from the owner of the Trade Mark(s) to grant a licence to Licensee on the terms and conditions of this Agreement.
(B) Licensee wishes to use the Trade Mark(s) in the Territory in relation to the Licensed Products and Services (as defined below), and Licensor is willing to grant to Licensee a licence to do so, on the terms and conditions of this Agreement.
