What is the patent stamp fee reduction/exemption system

Patent applications require stamp fees such as examination request fees and patent fees (annuity fees). These costs can be particularly burdensome for startups and small businesses.

The "reduction and exemption system" has been established to reduce this burden. Due to the system reform on April 1, 2019, the procedures have been significantly simplified, making it easier for more companies to use it.

Please note:This article is based on system information as of April 2019 enforcement. The requirements and reduction rates for the reduction/exemption system are subject to change, so please check the Official website of the Japan Patent Office for the latest information.

Key points of the new reduction/exemption system: No need for a certificate

The biggest change in the system revision in April 2019 is that submission of exemption application forms and certificates is no longer required.

In the previous system, it was necessary to prepare and submit various certificates in order to receive exemptions, and the problem was that the procedures were complicated. Under the new system, exemptions can now be granted only through self-reporting, greatly reducing the effort required to apply.

Main improvements of the new system

  • No need to attach certificate (self-declaration system)
  • Easy to use for startups and small businesses
  • Expand reduction rate (reduced to 1/3 for venture companies)

Reduction details for venture businesses (corporations and sole proprietors)

Venture-based corporations and sole proprietorships can receive significant reductions by meeting the following requirements.

Target expenses Reduction rate
Examination request fee Reduced to 1/3
Patent fee (1st to 10th year) Reduced to 1/3

The requirements for receiving this reduction are different for sole traders and corporations.

Division Requirements
Sole Proprietor Being in business for less than 10 years
Corporate (1) The company has been established for less than 10 years, and the amount of capital or total investment is 300 million yen or less
(2) Not controlled by a large company (a corporation with a capital amount or total investment of more than 300 million yen)

Reduction details for small and medium-sized enterprises (corporations and sole proprietors)

Even if you are a corporation or sole proprietor who does not meet the requirements for a venture (e.g., established 10 years or more), you can receive a 1/2 reduction if you meet the conditions such as number of employees and capital.

Target expensesReduction rate
Examination request fee Reduced to 1/2
Patent fee (1st to 10th year) Reduced to 1/2

The requirements for each industry are as follows. Either the number of employees or the amount of capital must be met.

Division Industry Number of employees in constant use Capital amount or total investment amount
A Manufacturing, construction, transportation, and other industries Less than 300 people 300 million yen or less
BWholesale Less than 100 people Less than 100 million yen
C Service industry Less than 100 people Less than 50 million yen
D Retail 50 people or less Less than 50 million yen
E Rubber product manufacturing industry (excluding automobile/aircraft tires, etc.) 900 people or less 300 million yen or less
F Software industry or information processing service industry Less than 300 people 300 million yen or less
G Hotel industry Less than 200 people Less than 50 million yen

Notes when using the system

Notes on self-reporting system

The new system does not require the submission of certificates, but it is assumed that the requirements are met. Please note that if you make a false declaration, your exemption may be cancelled.

In order to effectively utilize the reduction/exemption system, please keep the following points in mind.

  • Before filing, check whether your company's industry, capital, and number of employees meet the requirements
  • Even if you do not meet the requirements for venture businesses, you may be eligible for reduction under the small and medium-sized business category
  • Check the details of the system and the latest requirements on the Japan Patent Office's "Reduction and Exemption System" page
