Japan

Thomson Innovation offers both machine-assisted translations of Japanese patent documents, and the native language document collections themselves. This section will describe both collections.

English Machine-Assisted Translation Collections

Innovation contains two proprietary databases of full text machine-assisted translations for Japanese documents: one for published applications, and another for granted patents. Both collections are updated monthly. According to Thomson Reuters representatives, the phrase "machine-assisted translation" in this context means that the record is produced by a machine translation tool, and is then reviewed by a human indexer to correct untranslated terms.

Full text machine-assisted translations for Japanese published applications (JP-A) exist in the database from 2003-present. In addition, bibliographic data (including hand-translated English abstracts produced by JAPIO, where available) exists in the database from 1976-present. Front page drawings are present from 1980-date, if the coverage is equal to the former MicroPatent PatentWeb file.

Full text machine-assisted translations for Japanese granted patents are available from 2005-present, and limited coverage is available from 1998-2004. (Information about bibliographic data for these patents is not present, but the worldwide bibliographic INPADOC collection will include this data, and this file is also hosted by Innovation.) Information about drawings coverage is not included in the Innovation help file, but coverage probably corresponds to about 1980-date.

The Thomson Innovation Japanese translations are notable because the machine translation is only an assist to Thomson Reuters' Japanese-language editors. Whenever there are multiple English synonyms for the Japanese word originally used in the patent, the Thomson Reuters' machine-assisted translation will generate all of the possible English synonyms, to increase the chance that the document will be picked up by a keyword hit. These machine translations are then reviewed by Thomson Reuters editors, who choose the most appropriate synonyms from the list of choices generated by the machine translation (supposedly with reference to the intended meaning in the original text). In cases where multiple synonymous keyword terms are generated, the editors will leave all appropriate terms in the final translation, enabling keyword searches using either alternative to successfully find the record. Comparing the two examples below, this multiple-synonym feature is evident in the Thomson Reuters translation.

Example paragraph from JPO machine translation, JP3989943B2, Claim 1:

“The wing section which has the first transition section attached in the body, The actuator which twists said wing section to the circumference of said first transition section in a next predetermined period from before reversal of the movement direction in said flapping-of-wings reciprocating motion while making said wing section flutter and reciprocate to a cross direction, When the torque or energy required of said actuator for said flapping-of-wings reciprocating motion is smaller than a predetermined value, energy is accumulated from said actuator, and when the torque or energy required of said actuator for said flapping-of-wings reciprocating motion is larger than a specific value, it has energy are recording / supply device in which energy is given to said actuator, Said flapping-of-wings reciprocating motion consists of movement with a fixed angular velocity, and movement for reversal of said movement direction where it is carried out succeeding this movement and angular velocity changes, Said energy are recording / supply device is flapping-of-wings surfacing migration equipment which accumulates energy only in the first half of movement for reversal of said movement direction from said actuator, and gives energy to said actuator only in the second half of movement for reversal of said movement direction.”

Example paragraph from Innovation, JP3989943B2, Claim 1:

“The blade|wing|shuttlecock part which has the front-edge part attached to the main body, While making the front-back direction carry out the flapping reciprocating motion of the said blade|wing|shuttlecock part, it is the predetermined period of before inversion of the exercise|movement direction in the said flapping reciprocating motion to the back. WHEREIN: The actuator which twists the said blade|wing|shuttlecock part to the circumference of the said front-edge part, When the torque or energy request|required of the said actuator for the said flapping reciprocating motion is smaller than predetermined value, energy is accumulate|stored from the said actuator, When the torque or energy request|required of the said actuator for the said flapping reciprocating motion is larger than a specific value, the energy-storage * donation mechanism in which energy is given to the said actuator is provided, The said flapping reciprocating motion is an exercise|movement with a constant angular velocity, It consists of the exercise|movement for inversion of the said exercise|movement direction where it is carried out succeeding this exercise|movement and an angular velocity changes, And The said energy-storage * donation mechanism accumulate|stores energy only in the first half of the exercise|movement for inversion of the said exercise|movement direction from the said actuator, The flapping floating up movement apparatus which gives energy to the said actuator only in the second half of the exercise|movement for inversion of the said exercise|movement direction.”

Editor's Note:

Because of the long history of technical innovation in Japan, and the massive number of patent documents that have been filed there, the Japanese collections are essential to prior art searchers. The Thomson Innovation collections represent a substantial improvement in coverage not seen in other online databases. The collections are unique because they consist of full text machine-assisted translations produced by The Scientific Business of Thomson Reuters which are not available in any other patent search product. According to Thomson Reuters, a "machine-assisted translation" is produced by a machine translation tool, and then reviewed for accuracy by a human editor.

Because they are reviewed by human editors, these proprietary collections are said to be of superior quality to those available to the public via the Japanese Patent Office’s free IPDL (Industrial Property Digital Library) machine translation service.

In addition, this service is advantageous because these machine-assisted translations have already been produced, and the patent text exists in the database in English. Formerly, the Japanese application collection consisted only of hand-translated English abstracts. An English-language keyword search will query the full machine-translated text of these documents, increasing the chance of retrieval. On the other hand, it is also true that machine translations are often inaccurate, and if the Japanese text is inaccurately translated into English, this will increase the number of false drops. However, overall the achievement should be looked at in a positive light, as it generally makes relevant material more “findable.”

It is also notable that Innovation is the first search engine in its class to offer a collection of Japanese granted patents (JP-B) in addition to the published applications (JP-A). This will be an advantage to searchers investigating potential clearance or right-to-use issues in Japan. In addition, another advantage is that Innovation’s bibliographic coverage of Japanese published applications (JP-A) is superior to the old collection hosted by PatentWeb: Innovation covers bibliographic information back to 1976, while PatentWeb only has bibliographic records back to 1980.
