Japanese Patent Translation


Our strength lies in our ability to provide high-quality Japanese-to-English translation of patent specifications, both for filing outside Japan and for other uses, and we have an established track record in a broad range of fields of art that demonstrates our capabilities.

Documents We Handle

We handle not just patent specifications, but virtually any document related to the patent prosecution process and patent litigation, a partial list being as follows.

  • Patent specifications (for filing and other purposes)
    Specific instances of filing overseas (outside of Japan) have their specific requirements. We can provide English-language patent specification for filing overseas, in either US or PCT style. We can also provide translations for other purposes (e.g., submission as prior art), in which case a translation closely following the content and form of the original is usually required.
  • Procedural amendments
  • Written opposition
  • Appeals
  • Appeal against trial decision
  • Notification of reasons for rejection
  • Request for trial for invalidation
  • Arguments (written opinions)
  • Allowances
  • Complaints
  • Non-patent documents submitted as prior art
  • Final rejections
  • Licensing agreements
  • Powers of attorney
  • Non-disclosure agreements
  • Priority certification
  • Patent opinions
  • R&D literature
  • Court documents

Our Approach

Every Japanese patent translation assignment we accept is subjected to a process we have developed over the years for providing high-quality patent translation.

Initial Readthrough.  Our initial readthrough of Japanese patent documents we are asked to translate is basically to identify problems at an early stage that could arise during the actual translation process.

Verification of Bibliographic Information and Acquisition of Reference Materials.  Bibliographic information allows us to research and identify relevant reference materials. Naturally, receiving such reference material from our clients is very helpful, but given the bibliographical information, we can usually find the following type of information on our own.

Establishment of Terminology to Be Used.   Terminology we used needs to be both consistent within the Japanese patent document being translated and consistent with terminology conventionally used in the field of the art of the patent document being translated. To that end, we create job-specific glossaries for every assignment we accept, these glossaries including the following elements.

When necessary, the glossaries created also include notes on terminology to aid the patent translator. These glossaries are maintained by us indefinitely, and serve as a basis for future assignments.

Translation.  Once the above preparatory steps have been completed, the translation process itself begins. Unlike some of the mass-production translation providers, we never need to look for a heretofore unknown translator in a Third World venue to do your translations. Translations are only entrusted to known staff members who both understand the subject matter of the patent document and have years of experience in the patent translation field.

Questions.  During the translation process, questions might arise. Depending upon whether the translation is for filing or for other purposes, these will best be handled by the inventor or drafter of the patent (in the former case) or the entity originally commissioning the translation (in the case of US law firm clients commissioning translations). The fact that questions are asked should be understood as an indication that the translator realizes the importance of not speculating when correct information is close at hand.

Certified Translations

We can provide certified translations for prosecution or litigation. With regard to translations we have executed, we can provide a written certification of a translation, signed by the responsible translator, something that some other translation providers avoid by having someone else—often not a translator—sign such a letter.

As an additional service, given the original Japanese, we can bring translations done by other translation providers up to a level at which we could certify them. You should be aware however that, depending upon the quality of the original translation, the cost involved could be close to or the same as the cost of having a proper translation done from the start.

Things That We Both Do and Do Not Do Set Us Apart

Naturally, as Japanese patent translation boutique, we are committed to providing you with the highest possible quality. But there are a number of things that we promise we will not be doing when you issue an order for translation. These things distinguish us from the mass-production translation brokers that seem committed to volume over quality.

Additional Services

When requested as part of an investigation of prior art (e.g., at the behest of a US law firm), we can often easily obtain documents that are referenced in US prosecution but that are difficult to obtain from the US. One example is the case in which a subsequent application in Japan calling on a previous filing as priority is filed before the previous application is laid open. In such cases, although the data from the original filing (which is treated as having been withdrawn) is not available on the JPO website, we can usually obtain the original application by simply visiting the JPO directly, taking advantage of our location in Japan. If you are faced with such problems or other problems in obtaining Japanese documents, feel free to contact us for assistance.
