Exceptions to Lack of Novelty of Invention

Q1. We understand that Japan has a grace period for avoiding certain public disclosures from constituting prior art against a Japanese application.  How long is this grace period?

A1.  The grace period defined under Article 30 of the Japanese patent law (Exceptions to Lack of Novelty of Invention) is 6 months from the date of public disclosure.

Q2. What type of disclosures is capable of taking advantage of the Exceptions to Lack of Novelty of Invention in Japan?

A2.  According to current Article 30 of the Japanese patent law (effective as of April 1, 2012), virtually any disclosure, including “inventions made public at meetings and seminars, which are not academic conference designated by the Commissioner of the Patent Office, inventions made public on TV and radio, and inventions made public through sales”, are covered by the Exceptions to Lack of Novelty of Invention.  However, a patent publication is not a non-prejudicial disclosure.

Q3. Is the grace period applicable to scientific articles published on the web? 

A3.  The 6-month grace period is also applicable to electronic publications of scientific articles.  When a scientific article is published in the form of an electronic publication in advance to the publication in print, the 6-month grace period will start from the date of the electronic publication.  This rule applies not only to a free electronic publication, but also to an electronic publication which requires registered membership and/or purchase of the publication for accessing the electronic publication.

Q4. An invention has been published as a scientific article and a basic patent application has been filed in the US within 6 months from the publication of the scientific article.  Already 10 months have passed from the publication of the scientific article, but is it still possible to enjoy the benefit of the Japanese 6-month grace period by filing a Japanese patent application claiming the Paris convention priority from the basic US application filed within 6 months from the publication date? 

A4.  No.  Claiming of the Paris convention priority does not allow the filing date in Japan to date back for the purpose of grace period.  In other words, when a basic application is filed in other country within 6 months from the date of public disclosure, and a Japanese patent application claiming the convention priority from the basic application is filed after the expiration of the 6-months grace period, the Japanese patent application cannot enjoy the benefit of the grace period.

For receiving the benefit of the 6-month grace period in Japan, the Applicant must file within the 6-month grace period either one of the following applications:

   (1) Japanese national patent application*, or

   (2) PCT application designating Japan as one of the designated states. 

* Either a Japanese patent application or a PCT application claiming the convention priority from this Japanese patent application can be filed after the expiration of the grace period and still enjoy the benefit of the grace period.

Q5. What are the steps necessary for obtaining the benefit of the Japanese 6-month grace period?  

A5.  Necessary steps are explained separately for Japanese national patent application and PCT application.

Japanese national patent application:

A patent application is filed simultaneously with a Request for Grace Period within 6 months from the date of public disclosure.  Alternatively, the Request may be omitted by stating such effect in the patent application.

Next, a Document Verifying the Request, which is signed by all applicants, is filed within 30 days from the filing date of the patent application.  Filing of a specific evidence material (such as a copy of the scientific article disclosing the invention) is not required, but it is most advisable to file the evidence material with the Document.

PCT application designating Japan:

When a PCT application designating Japan as one of the designated states is filed within the 6 month grace period, such a PCT application will obtain the benefit of the grace period even when the PCT application enters the Japanese national phase after the expiration of the grace period (i.e., within non-extensible 30 month deadline).  In this case, both the Request for Grace Period and the Document Verifying the Request are filed within 30 days from the entry into the Japanese national phase. 

[Filing of the Request for Grace Period can be omitted when “Declaration as to Non-Prejudicial Disclosures or Exceptions to Lack of Novelty” (PCT Rule 4.17(v), 26ter.1) is made at the international stage.]

The Document Verifying the Request can be prepared at our end and forwarded for execution by the applicant(s).

Q1. 日本の商標登録出願に基づく優先権主張をして外国に商標登録出願する場合、特許の場合と同様に、日本出願から1年以内に外国出願すれば良いのか?

A2. パリ条約に基づく優先期間は、特許については1年ですが、商標については6ヶ月と定められています。従って、日本の商標登録出願の日から6ヶ月以内に外国出願手続きを完了させなければ優先権を享受することはできません。

Q2. 直接外国へ商標登録出願することに対する国際商標出願(マドリッドプロトコル出願)のメリットとデメリットは

A2. マドリッドプロトコル出願(所謂「マドプロ出願」)のメリットとデメリットは以下の通りです。









Q3. マドリッドプロトコルの加盟国は

A3. 現在のところ、日本、米国、EU、ロシア、中国、韓国などを含む86カ国が加盟しています。近年、注目を集めている新興国では、ベトナム、フィリピン、イラン、エジプトなどは加盟していますが、マレーシア、タイ、インド、インドネシア、メキシコ、バングラディシュなどの国は未加盟です(2012年9月現在)。詳しくは、こちらで確認できます。

Q4. 展示会に自社製品を出品するにあたり、新たな商標を使用しようと考えているが、特許出願の場合のように、展示の後に、新たな商標について新規性を喪失せずに出願することはできるのか?

A4. まず、商標に関しては、特許におけるような所謂「新規性」という概念は存在しません。特許、実用新案、意匠等は、新たな技術などを発明、考案又は創作し、その新しい技術などの保護を目的とするものですが、商標権は「選択物」であると言われます。これは、商標権に関しては、既存の言葉などを選択して特定の商品やサービスを特定するために用いる権利であるという考え方に基づきます。

Q1. If a trademark application is to be filed in Japan claiming Convention Priority based on a non-Japanese application, is the priority period one year as in patent applications? 

A1.  No. For filing a trademark application in Japan claiming Convention priority, the priority period is six (6) months, instead of one year, from the filing of the priority application. 

Q2. Are there any specific points to be noted for registering a trademark in Japan?

A2.  Some of the points to be noted for registering a trademark in Japan are as follows.

(1)  Goods and services acceptable in Japan:  In the case of trademark registration in Japan via Madrid protocol, the JPO may object to the indications of goods/services in the International Register as being too vague even if they should be acceptable under the NICE Agreement.  This is because the JPO relies on its own list of goods and services as prescribed in the examination standards.  For example, “Apparatus for locomotion by land, air or water” found in the NICE Classifications is not found acceptable by the JPO, and it should be amended to “Aircraft; automobiles; bicycles; motorcycles; rolling stock for railways; ships”.  The amendment of indications is possible as long as it is within the scope of the original Madrid protocol application. 

(2)  Requirement for use of trademark:  A registrable trademark in Japan is a trademark which is being used or which is intended to be used in the near future.  When the range of the goods and services listed in one class is too broad, the trademark will be rejected because the veracity of use or intention of use of the trademark becomes doubtful.

(3)  Registrable subject matter:  Currently, sounds, smells, colors, textures, tastes and movements are not registerable as trademarks in Japan.  (However, the JPO is planning to submit a bill to revise the trademark law to the Japanese Diet in 2013.  So, registration of the mentioned subjects as trademarks may become possible in the near future.)

Q3. Are there any means to accelerate examination of a trademark application in Japan?

A3. Yes.  A request for accelerated examination can be filed anytime after the filing of your trademark application, and the request should be granted as long as the following condition 1 or 2 is met .

Condition 1 : Actual use of trademark and need for quick registration 

You or your licensee is already using your trademark for the goods or services designated in your application, or are preparing to use the trademark, AND

The trademark rights need to be granted urgently due to any one or more of the following reasons:

   1) A third party is using a trademark which is the same or similar to your trademark without authorization from you or your licensee, in connection with designated goods or services that are the same or similar to the goods and services for which you or your licensee has been using the trademark, or for which you or your licensee has prepared to a considerable degree to use the trademark.

   2) A third party has given a warning with respect to the use of your trademark.

   3) A third party is demanding an agreement to their use of your trademark.

   4) You have also applied for the trademark registration at a Patent Office other than the Japan Patent Office (JPO), or to an intergovernmental organization.

Condition 2:  Use of trademark only for designated goods or services

Your application designates only the goods and services for which you or your licensee is already using the trademark or you or your licensee is preparing to use the trademark.

Q4. What are the documents necessary for filing a request for accelerated examination for a trademark application in Japan? 

A4.  A document entitled "Explanation of the Circumstances Concerning Accelerated Examination” should be filed together with evidence(s) showing that the above-mentioned Condition 1 or 2 is fulfilled by the trademark application. 

Q5. What are the specifics of the individual fee system for a trademark registration via Madrid Protocol designating Japan. 

A5.  The JPO has adopted an individual fee consisting of two parts in accordance with Rule 34(3)(a) of the Common Regulations under the Madrid Protocol.

First part of the individual fee:  This corresponds to an application fee, and is paid at the time of international registration or the subsequent designation. 

Second part of the individual fee:  This corresponds to a registration fee, and is paid within the prescribed period mentioned in the notification issued with the Notice of Grant.  Failure of payment results in cancellation of the designation of Japan in the international registration.

Both fees are to be paid directly to the International Bureau of the WIPO.
