If you have invented a new mug and called it The Coffeeheater. It is installed with device to keep your coffee warm for longer. A Registered Design will protect?

A Registered Design will likely partially protect your Coffeeheater mug. Here's why:

What a Registered Design Protects:

* Visual Appearance: A Registered Design protects the overall appearance of your product, including its shape, configuration, pattern, and ornamentation.

* Not Function: It doesn't protect the underlying technology or functionality of the device that keeps the coffee warm.

How it Applies to The Coffeeheater:

* Protected:

* The unique shape of your mug (assuming it's distinct).

* Decorative elements like a specific pattern, logo, or color scheme.

* Not Protected:

* The internal mechanism that keeps the coffee warm. Someone else could create a mug with a different design but using the same heating technology without infringing on your design.

* The concept of a self-heating mug.

Additional Considerations:

* Patent Protection: For full protection of the heating technology, you would need to consider a patent.

* Trademarks: You'd need a trademark to protect your brand name "Coffeeheater."

In Conclusion:

A Registered Design will give you some protection for the Coffeeheater's appearance, but not for its functionality. To fully protect your invention, you may need to consider both design and patent protection. It's always best to consult with an intellectual property lawyer to understand the best approach for your specific invention.
