Takeaways
When determining the similarity of designs, how is a court's judgment affected when a design element has commonality with a functional element? A recent Supreme Court decision provides some insight into this question.
The determination of whether designs are similar should be judged not by separating and contrasting the individual elements, but instead in accordance with the aesthetic sensibilities of a viewer observing and contrasting the designs as a whole. However, where the common parts of the designs are an intrinsic part of the product, or a basic or functional form of the design, such parts should be given low importance and the compared designs should not immediately be deemed identical or similar based only on the identity or similarity of such parts.(1)
Per existing precedent, in Decision 2016 Hu1710 (3 September 2020), relating to cargo vehicle toolbox designs, the Supreme Court ruled that where the common parts of compared designs are an intrinsic part of the product, or a basic or functional form of the design, such parts should be given low importance. However, the court additionally ruled that if it is possible to select an alternative form which can secure the function of the product (Figure 3), such form is not essential in securing the function of the product and instead simply relates to the function. As such, it should not be given low importance when determining the similarity of the designs just because it is related to the product's function.
In this case specifically, the court stated that the registered design in question and the preceding design had the following in common:
The court stated that the parts in common were not seen as being essential in securing the function of the cargo vehicle toolbox and that, in commerce, consumers were expected to consider the aesthetic of the designs as a whole, including the common features of the above parts. Accordingly, such parts should not be given low importance when determining the similarity of the designs just because they related to the product's function, or were invisible after installation, and the similarity of the designs should be judged in accordance with the aesthetic sensibility felt when observing the designs as a whole, including such common parts.
The court went on to rule that while the registered design in question and the preceding design differed in respect of the following, when observed as a whole, the designs were aesthetically similar and should thus be regarded as similar designs:
Looking at this precedent, it appears that the registered design in question was not strictly necessary to secure the function. Rather, as a selectable alternative form existed (eg, the known design shown in Figure 3), the registered design in question was not seen as essential in securing the function of the cargo vehicle toolbox and so should not be given low importance when determining the similarity between the designs.
In principle, if the common part of designs being compared is a basic or functional form of the product that has been widely used before the filing date of either design in the field to which the designs belong, the court should give low importance to such part when determining similarity. However, if the common part is not essential in securing the function of the product, when determining similarity between designs, the designs should be considered as a whole, including such common part.
Therefore, if there is commonality between a to-be-applied-for design and an existing design, where such common part is a basic or functional form of the product that has been widely used in the field to which the designs belong, it is necessary to consider whether:
