Why register your Trademark?
In short, if you do not register your trademark then somebody else can which immediately puts your business at risk and any products or services you are currently in the midst of. By registering a trademark you can protect your brand and therefore protect your business. After registration you can prevent someone from using similar logo's/trademarks and stop them from gaining momentum off the current/future success of your business.
Once you have created a trademark for your business, if left unregistered, you may find that you have to cease providing the goods or service you have spent time building up and the reputation you have gained a long the journey will all be put to waste. Changing the name of a company can be a difficult and costly undertaking. By protecting your trademark and therefore protecting your investment, you will add increased security.
