When you register a design, you protect the external appearance of the article or non-physical product and have the right to control its use.
As an owner of the registered design, you can prevent others from using the design without your permission.
You can also use your registration to protect your market share by barring others from copying, license it to third parties for commercial returns or sell the design for monetary returns.
Once your design is registered, it will be protected for an initial 5 years from the date of filing. Thereafter, the registration is to be renewed every 5 years, up to 15 years.
