Foreign Document Investigation

About the survey method

At Wisel, when we investigate international documents (Patent Literature and Non-Patent Literature), we use the following methods in combination with technological analysis, investigation purpose, and target country.

(1) Surveys conducted by our investigators or registered investigators (outsourced)

We use commercial databases such as Derwent Innovation, Orbit Intelligence, JP-NET, SRPARTNER, STN, and CNIPR, as well as databases from national patent offices.

(2) Requesting an investigation from an overseas investigation company or agent

We will ask a reliable private law firm or patent office overseas to conduct a search. Local patent office databases are available.
