When a brand or Trademark of a person or company is copied or duplicated by other party in anyway whether by having similar look or similar sound or by deceptive similarity or the mark or brand of other party appears anyhow associated or connected with the first party, such an act of the other party is called infringement of the Trademark and passing off on the goodwill of the first party.

In this case the aggrieved person from infringement and passing off may resort to the legal action by sending a legal notice of Trademark Infringement and passing off.

To be noted that a strong legal notice of Trademark Infringement and passing off mostly deter the parties involved in the act of Infringement and passing off while some of the parties require legal actions of the court after the notice of Trademark Infringement and passing off.
