The Global Leader of Innovation: How Japan Aims to Lead Again

Japan has for long been the global leader of innovation and creations. Over the past deacde, however, other jurisdictions, such as China, have slowly grown and produced tighter competition; Japan’s dominance leading patent applications has slowly faded, and so we speak with Tomoyuki Serizawa, a leading patent attorney, who discusses the changes in place that will enable growth in Japan.

 

What changes have you witnessed in the past few years regarding patents in Japan?

In Japan, opposition system was resumed in April 2015. Currently, Japan has two options to invalidate a patent: one is opposition and the other is trial for invalidation. From April 2015 to March 2017, the Japan Patent Office (JPO) received about 1900 oppositions. According to the statistics, among 990 decisions of the oppositions, the number of decisions to maintain a patent is 884 (about 89%); to revoke a patent was around 90 (about 9%); and dismissal decisions 16 (about 2%). Among 884 decisions to maintain a patent, 370 cases (about 37%) are maintained without any correction to patented claim(s), while 514 cases (about 52%) are maintained with correction to patented claim(s). In other words, it is considerably difficult to revoke a patent using an opposition system in Japan.

Furthermore, the employee invention system was revised in 2015, which came into effect from April 2016. In the new system, a company has an original right to obtain a patent for employee invention, based on agreement between the company and the employee (inventor), employment regulation, etc. An employee has a right to receive reasonable remuneration or other economic profits (reasonable profits). A company can give the employee profits (e.g., opportunity to study abroad, to grant stock options) instead of remuneration.

 

In what ways do you think Japan led the world of patents, after being a global leader in innovation?

Japan plays an important role in effective utilisation of patent examination in respective countries. In 2006, the JPO proposed a Patent Prosecution Highway (PPH) programme for utilising the examination result conducted by one patent office in the examination of another patent office. The JPO still continues to encourage respective foreign patent offices to participate in this PPH program. The PPH program is a kind of accelerated examination program such as PACE programme in European patent system. The PPH programme requires all claims to be examined and must sufficiently correspond to allowable or patentable claims in the other foreign patent office. As of December 2015, 36 patent offices participated in the PPH programme and the total number of the requests for the PPH programme reaches about 88,000.

 

Nevertheless, are there any changes you are looking forward to that are occurring in the next year?

The Government seems to be considering a system for procedures that enable appropriate evidence collection in patent infringement litigation. Since Japan does not employ a discovery system, it is difficult for a plaintiff to obtain evidence to establish the fact of infringement in patent infringement litigations. Under the current Patent Act, it is possible that the court issues a “document submission order”, which requires parties to submit documents for establishing the infringement acts or for calculating the amount of damages. However, due to strict requirements imposed on the document submission order, it is rarely issued in patent infringement litigation. Meanwhile, the above documents owned by a defendant generally include trade secrets important to their business.

Thus, the government is now considering a system in which a third party technical expert having the duty of confidentiality can involve in evidence collection procedures.

Will any of the above changes which are proposed / rumoured to occur, help tackle competition Japan has seen increase over the years from China?
Yes. By introducing appropriate evidence collection in the patent infringement litigation system, a patent owner will be able to enforce his/her patent right more easily. This will improve the motivation to acquire a patent in Japan, and will push up investment activity for innovation, thereby giving a positive impact to a global technology competition with China.

 

The Supreme Court in the US rules that patent law cannot stop the resale of products; as Thought Leader, what is your stance on this ruling?

In Japan, the sale of patented products exhausts a patent right domestically, but does not exhaust it internationally (BBS Supreme Court Case, July 1, 1997). If there is a restriction for prohibiting patented products sold abroad from being imported to Japan, the resale of the patented products sold abroad will infringe a Japanese patent right. Unless there is the above restriction, the resale of the patented products sold abroad will not infringe the Japanese patent right under the doctrine of implicit licensing by the patent owner.

In my opinion, the international exhaustion should not be admitted, because the scopes of patented claims for a particular invention are not necessarily the same in different countries. Taking an example of software related inventions, it is possible that applicant can obtain a patent right with a broader scope in Japan than in the United States.
