Flowchart for Registration (Patent)
Time Required for Registration
Depending on a technical field and a subject
matter of an invention, it takes about 2-4 years
from application to registration. This period can
be shortened to 6-10 months by filing an
accelerated examination request.
Preparation for Application
We place great value on a preparation meeting
with clients to understand subject matters of their
inventions in an appropriate manner. We can offer
professional advice to acquire the wide and
effective scope of the patent right.
Flowchart for Management (Patent)
After decision to grant a patent, a patent fee for
the first three years must be paid in a lump to the
Japan Patent Office. To maintain the patent right
for more years, the patent fee for each year must
be paid in advance by the end of the previous
year.* The patent fees for multiple years shall be
payable in a lump. In principle, the duration of
the patent right shall expire after a period of 20
years from the filing date.
*E.g., the patent fee for the fourth year shall be
paid by the end of the third year from the date of
the registration establishing the patent right.
