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.
The use of a Trademark Symbol is entirely optional.
By simply having a logo, you have what's known as a common law trademark for your logo. That means that, without doing anything paperwork-wise, you have the sole legal right to use and amend that logo as you see fit. But without an officially registered trademark, that right isn't as secure as it could be.
Without permission, using a trademark can lead to infringement claims, which can have significant legal repercussions. To avoid such scenarios, it's crucial to seek proper authorization before using someone else's trademark.
A mark may qualify as a valid trademark only if it meets three separate requirements: it must be distinctive, nonfunctional, and used in commerce. Trademarks must be distinctive enough to serve their basic function of distinguishing one seller's goods from another's.
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.
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.
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.
