A trend in recent years has been to raise product quality and provide added value. In line with this has come a rising awareness of the need to protect rights in these products. A design appeals directly, and in an easily understood way, to our sensibilities. Because of this, a design is an important way to raise quality and provide added value in a product.
Strategic use of designs is called for in most fields in which products compete and in technologically mature fields. An independent protection system is established by the Design Act. An article that satisfies the requirements can be registered to obtain a design right and receive protection in the form of an exclusive design right extending for a maximum of 20 years from the time of registration. The highly experienced patent attorneys at Asamura Patent Office look forward to supporting your company in its registering of design rights.

Talk to us

The registration of a design right involves not only the entire design of an article, but also extends to a part of the overall design or a certain set of multiple products—what is called a system design. Designs that change in shape based on the functions of the article are also accepted.
Let us show you how to utilize the design right protection system for your product design. So, if you have any designs currently under investigation, why not talk to us first?


Conducting a search is not simply about whether a new design can be registered. Prior to producing a new product for sale, it is wise to carry out a search of prior registered designs in order to find out whether the design of the new product might infringe existing design rights of another party. Asamura Patent Office is happy to support you by conducting a search of prior registered designs in various fields with existing design registrations.
