In some countries, it is enough to prepare only one or two drawings for filing a design patent application.
That’s why I sometimes receive a request for filing a new design patent application in Japan from my foreign client with only one or two drawings to show a design.
However, it’s not sufficient in most cases in Japan.
In principle, it is required to file a set of orthographic drawings which include the followings:
- Front view
- Rear view
- Left-side view
- Right-side view
Furthermore, all of the drawings must be shown by the same scale.
In the light of the above, you should make the above six drawings at least before filing a design patent application in Japan if you are interested in obtaining a design patent there as well as in your country.
