Keyboard Shortcut: On a Windows computer, you can use the keyboard shortcut “Alt + 0153” (numeric keypad) to insert the trademark symbol (™). Make sure the Num Lock is enabled. On a Mac, you can use the keyboard shortcut “Option + 2” to insert the trademark symbol.
It depends. Higher value tends to lie in name recognition rather than familiarity of a logo. Since logos change more often than names, it usually makes more sense to register a standard character mark to protect the business moniker itself.
The short answer is no, you do not. But you do need to use it in traditional places where a company name would be found in order to enjoy the limited liability.
Once your trademark is registered, the best practice is to place the R symbol next to it at its first or most prominent use in each piece of material. Place the trademark symbol at the top or bottom right of your brand name, logo, or tagline.
