Activity Title: Chocolate wars: Nestle loses bid to trademark KitKat shape

Topic: Auxiliary View

Objective: Creating the proper engineering views to describe an object.

Material: KitKat Candy Bar


KitKat believe that the shape deserves to be protected as a trade mark in the United Kingdom and are
disappointed that the court did not agree on this occasion. A bid to register the shape of a four-finger KitKat as a trademark was given the thumbs down by a High Court judge. The Swiss firm is attempting to protect the four-finger bar’s shape, but its competitor says that would give them an unfair advantage in the UK’s £3.5bn chocolate market. He said aspects of European trademark law were “unclear” and that he wanted clarification from the Court of Justice in the European Union before coming to a decision. This is the latest decision in something of a chocolate turf war between Nestle and Cadbury. Britain’s High Court on Wednesday upheld those decisions, ruling that the shape of a KitKat bar has not “acquired a distinctive character” enough to satisfy trademark requirements. It’s the world’s third-biggest chocolate brand. Its case was not helped by the existence of a similar Norwegian bar, called Kvikk Lunsj, which means “quick lunch” and has been around since 1937. A Mondelez spokesperson said the latest ruling “is in line with our contention that the shape of the Kit Kat bar is not distinctive enough to be protected as a trademark”. If a rival bar is up Cadbury’s sleeve, the candy-maker might consider calling it “Kit for Kat”, just to ensure the legal battle keeps going. Nestle, which makes KitKats, told CBS MoneyWatch that it plans to appeal the judgment. Kit Kats are four thin fingers of wafer covered in chocolate which were originally created in Britain in 1935.

Trapezoidal Prism: Prisms are geometric solids that come in many different shapes and an infinite number of sizes. Prism are often distinguished by the shape of their base polygon. A prism having trapezoid base faces is called a trapezoidal prism.trapizoid

Where, a, b be length of the top and bottom of the trapezoid and h be the height of the trapezoidal. And ‘l’ be the length or height of the trapezoidal prism.


STEP 1: Auxiliary Views

Given: Auxiliary views are often necessary to show the true shape and length of inclined surfaces, or other features that are not parallel to the principal planes of projection. Look directly at the front view of the figure below. Notice the inclined surface. Now look at the right side and top views. The inclined surface appears foreshortened, not its true shape or size. In this case, the draftsman will use an auxiliary view to show the true shape and size of the inclined face of the object. It is drawn by looking perpendicular to the inclined surface. The figure shows the principle of the auxiliary view.


Procedure: Use the provided “KitKat Bar” to sketch the CANDY AS YOU SEE IT RIGHT OUT OF THE Package front, top, right side, and isometric views in the space provided. Then at 90 degrees, draw the two auxiliary view.

1: Explain why auxiliary views are important?

2: What other objects would benefit from an auxiliary view.

3: If an object has a hole on an angled surface. How does the hole appear on the top, front and side views.
