We trademark names and symbols in the US, Israel and worldwide. The trademark is generally a recognizable sign, design or expression used to identify products or services. Most countries including Israel require formal registration of a trademark before pursuing legal action against infringement (when another entity uses an identical or nearly identical design for related or identical goods or services).
The ™ symbol denotes an unregistered trademark. ℠ is used for 'service marks' (where a service is being marked instead of a good), and ® is for a registered trademark or service mark.
