Bear in mind that it is the local law, and not always the government that trademarks things. For instance, in the United States, the local court of law decides whether or not a commodity is worthy of being trademarked. For example, if you wish to find out how to trademark photography, then understand that all you have to do is use your brand name in commerce and you earn the right to put “TM” next to your work. In many cases, as social media is booming, all you have to do is watermark your work. Did you find this useful?
