Value of searching Japanese patents


  • Japan is easier to find patents that can invalidate target

Japan was the top patent filing country until early 2000s. Higher chance to find prior art that examiners overlooked in the prosecution.


  • English translation of entire specification is hardly available

Even widely-used commercial databases provide English translation of abstract only, not the entire specification.


  • Machine translation does not work well for Japanese-to-English translation

Compared to other languages, Japanese is difficult to translate. Time and cost can be inflated for translation.


Japan is a gold mine of prior art.

Only Japanese search company can find prior art that is exactly needed.

CEO Yoshinori Matsumoto

From proposing search plans based on direct hearing with in-house engineers to advising on building IP strategy including establishing relationship with attorneys, Logic Meister has supporting companies since its foundation in 2001.

We are not just a patent service firm but rather “outside IP division of your company”.



Our founding members are composed of the IP experts and experienced engineers in machine, semiconductor and software manufacturer.

From that time, there was connection with the people involved in various industries.

Here is the story I often heard at network events from those people.

“The more our products are sold, the more IP issues emerge.

As we do not have in-house IP experts in the company, people in charge of general affairs and engineers are forced to handle these matters. This is a huge problem.”

“We can seek legal advice for lawyers and patent attorneys, but they cannot give us advice on how to arrange work within the company.

We need guidance from experts who can fully understand the company.”

Meanwhile companies can expand a patent division when they have a number of challenges related to their IP assets, and they can downsize the division once their technology matures and they file less patent applications.

As a result, some companies fail to determine whether to file patent applications in terms of cost effectiveness.

Some wildly file a number of applications, and some fail to file necessary applications in the particular technology field due to a lack of communication between its patent division and engineers.

Given that situation, I thought it would be helpful for those companies if I could work for them as an ‘outside’ work-ready member of the patent division providing advice anytime they need.


We provide solutions to maximize value of your IP assets focusing on searches but also utilizing our various experiences in product design development, litigation, R&D-IP liaison, licensing negotiations.
