Design similarity judged on overall appearance rather than functional necessity

Supreme Court, Sept. 3, 2020, 2016Hu1710 (judgment)

Case name: 등록무효(디)

Official text on the National Law Information Center

  1. Question

    When judging whether a registered design for a cargo vehicle tool box is similar to a prior design, must similarity be decided on the overall appearance rather than on individual components, and may a common part for which alternative selectable forms can secure the article's function be evaluated as less important?

  2. Holding

    It may not. Similarity is decided by comparing the whole appearance and asking whether it makes a viewer feel a different aesthetic impression, so that designs sharing the dominant features are similar even where details differ, and the aesthetic at the time of transaction counts alongside that at use. Where the common part is indispensable to securing the function of the article its importance is lowered, but where alternative selectable forms can secure that function the part is not indispensable and cannot be downgraded for being merely functional. Here the shared shapes of the tool box were not indispensable, and the differences in the embossed or debossed patterns did not displace the similarity of the dominant features, so the registered design was similar to the prior design and its registration had to be void.

    Summary of the holding, verbatim

    그러나 물품의 기능을 확보할 수 있는 선택 가능한 대체 형상이 존재하는 경우에는 물품의 기능을 확보하는 데에 불가결한 형상이 아니므로, 이 경우 단순히 기능과 관련된 형상이라는 이유만으로 디자인의 유사 여부 판단에 있어서 그 중요도를 낮게 평가하여서는 아니 된다.

    However, where there is an alternative selectable shape capable of securing the function of the article, since it is not a shape indispensable to securing the function of the article, in such a case the importance of that part must not be evaluated as low in determining the similarity of designs merely on the ground that it is a shape related to the function.

    Elements stated Stated in the decision

    디자인의 유사 여부는 이를 구성하는 각 요소를 분리하여 개별적으로 대비할 것이 아니라 그 외관을 전체적으로 대비 관찰하여 보는 사람으로 하여금 상이한 심미감을 느끼게 하는지 여부에 따라 판단하여야 하고, 그 지배적인 특징이 유사하다면 세부적인 점에 다소 차이가 있을지라도 유사하다고 보아야 한다.

    Unofficial English translation

    The similarity of designs must be determined not by separating and individually comparing each element constituting the design, but according to whether the appearance, when compared and observed as a whole, gives a person who sees it a different aesthetic sense, and if the dominant features are similar, it must be regarded as similar even though there are somewhat differing points in the details.
  5. Factors

    • 그 외관을 전체적으로 대비 관찰하여 보는 사람으로 하여금 상이한 심미감을 느끼게 하는지 여부에 따라 판단하여야 하고
    • 그 지배적인 특징이 유사하다면 세부적인 점에 다소 차이가 있을지라도 유사하다고 보아야 한다
    • 디자인이 표현된 물품의 사용 시뿐만 아니라 거래 시의 외관에 의한 심미감도 함께 고려해야 한다
    • 양 디자인의 공통되는 부분은 화물차량용 공구함의 기능을 확보하는 데에 불가결한 형상이라고 보기는 어렵고
    • 양 디자인은 몸체부 및 여닫이문 부분에 양각 또는 음각으로 형성된 무늬의 위치 및 모양 등 일부 차이점이 있기는 하나, 이러한 차이점이 양 디자인의 지배적 특징의 유사성을 상쇄하여 서로 상이한 심미감을 가지게 할 정도라고 보기는 어려우므로

  8. Open question and revisit condition

    What makes a form an alternative selectable form capable of securing the function of the article, so that a shared part counts as indispensable or not?

    A later Supreme Court decision on how alternative selectable forms are identified would require this entry to be read again, as would an amendment to Article 2(i) or Article 33(1) of the Design Protection Act. The registered number of the design in this case is omitted from the official text, so the drawings must be taken from the record.

Lower-court contrast & scope of application

Lower-court reading vs. Supreme Court holding

Lower-court context: The Patent Court, in its judgment of 15 July 2016 (2016Heo2010), held that the registered design for a cargo vehicle tool box was similar to the prior design and that its registration had to be void. The Supreme Court states only that the lower court's reasoning on the same lines was correct, so the Patent Court's own grounds are not set out in this text.

Supreme Court standard: The Supreme Court found no error in that reading. On the whole record it held that the shared parts were shapes rarely seen in earlier tool box designs, occupied a large share of the overall appearance and well showed the structural features of the article, so that they were likely to draw the demander's attention, and that being functional or hidden after installation was not by itself a reason to lower their importance. The Justices unanimously dismissed the appeal and placed the costs on the defendant.

Distinguishing conditions

  • A case in which the shared part of the two designs is indispensable to securing the function of the article, so that its importance is lowered and the similarity of that part alone cannot make the designs similar.
  • A case in which the differences between the designs reach the dominant features and give the viewer a different aesthetic impression.
  • A case in which the shared shapes are commonly found in earlier designs of the same article, so that they are not novel features drawing the demander's attention.

Record verification notes

Before relying on this decision, identify the article and the prior design exactly, then list every shared shape and ask for each whether it is indispensable to the function or whether alternative selectable forms exist. Compare the two designs at both the use-time and the transaction-time appearance, since the Court required both. Finally, set the differences, here the position and shape of the embossed or debossed patterns on the body and hinged door, against the dominant features rather than counting them one by one.

[1] Whether, in determining the similarity of designs, where there is an alternative selectable shape capable of securing the function of the article among the components of the design, the importance of that part may be evaluated as low in determining the similarity of designs (negative) [2] In a case where it was at issue whether a registered design with the subject article being "a tool box for a cargo vehicle" "" was similar to a prior design "", although the two designs have some differences in the positions and shapes of the patterns formed embossed or recessed on the body portion and the hinged door portion, such differences are difficult to regard as reaching the extent of offsetting the similarity of the dominant features of the two designs and giving them different aesthetic senses, and therefore the registered design and the prior design fall under similar designs

Summary of the holding

[1] 디자인의 유사 여부는 이를 구성하는 각 요소를 분리하여 개별적으로 대비할 것이 아니라 그 외관을 전체적으로 대비 관찰하여 보는 사람으로 하여금 상이한 심미감을 느끼게 하는지 여부에 따라 판단하여야 하고, 그 지배적인 특징이 유사하다면 세부적인 점에 다소 차이가 있을지라도 유사하다고 보아야 한다. 이 경우 디자인이 표현된 물품의 사용 시뿐만 아니라 거래 시의 외관에 의한 심미감도 함께 고려해야 한다. 한편 양 디자인의 공통되는 부분이 물품의 기능을 확보하는 데에 불가결한 형상인 경우에는 그 중요도를 낮게 평가하여야 하므로 이러한 부분들이 유사하다는 사정만으로 곧바로 양 디자인이 서로 유사하다고 할 수 없다. 그러나 물품의 기능을 확보할 수 있는 선택 가능한 대체 형상이 존재하는 경우에는 물품의 기능을 확보하는 데에 불가결한 형상이 아니므로, 이 경우 단순히 기능과 관련된 형상이라는 이유만으로 디자인의 유사 여부 판단에 있어서 그 중요도를 낮게 평가하여서는 아니 된다. [2]대상물품을 ‘화물차량용 공구함’으로 하는 등록디자인 ""이 선행디자인 ""와 유사한지 문제 된 사안에서, 양 디자인의 공통되는 부분은 화물차량용 공구함의 기능을 확보하는 데에 불가결한 형상이라고 보기는 어렵고 화물차량용 공구함의 거래 시 수요자는 위와 같은 공통된 부분의 특징들을 포함한 물품 전체의 외관에 의한 심미감을 고려하여 물품을 거래할 것으로 보이는데, 양 디자인은 몸체부 및 여닫이문 부분에 양각 또는 음각으로 형성된 무늬의 위치 및 모양 등 일부 차이점이 있기는 하나, 이러한 차이점이 양 디자인의 지배적 특징의 유사성을 상쇄하여 서로 상이한 심미감을 가지게 할 정도라고 보기는 어려우므로, 등록디자인과 선행디자인은 서로 유사한 디자인에 해당한다고 한 사례.
