A trademark and a brand are related but separate concepts. A trademark is a legal protection for a mark (such as a word, logo, design, or phrase) that is used to identify and distinguish the goods or services of one company from those of another. Trademarks are registered with government agencies, such as the Intellectual Property Organization of Pakistan (IPO-Pakistan) in Pakistan, and the registration process generally involves a review of the mark to ensure that it is distinctive and not already in use by someone else. Once a trademark is registered, the owner of the mark has the exclusive right to use it in connection with the goods or services for which it is registered.
A brand, on the other hand, is a broader concept that encompasses a range of elements, such as the name of a product or company, logos and visual elements, advertising and marketing campaigns, and the overall reputation and image associated with the product or company. A brand is often developed over time through a combination of marketing, advertising, and other activities, and can include many different types of trademarks, such as wordmarks, design marks, and trade dress.
So in short, a trademark registration is a legal protection of a specific word, logo or design while brand registration is broader concept which include trademark as a part of it and it encompasses a range of elements such as name, logo and reputation associated with the product.
It is generally good practice for a company to protect its brand by registering trademarks for the key elements of its brand, such as its name and logos, to ensure that they have legal protection for those elements.
