How to become one

No particular education or qualification is required for this job, but most people have at least a university degree. Those who handle patents usually come from science and engineering, and those who handle trademarks usually come from arts and social sciences. After joining, they build their skills through on-the-job training and outside courses on intellectual property searching as needed. To carry out searches at a registered search organisation that takes on search work from the Japan Patent Office, you must complete the statutory 'training for search staff' run by the National Center for Industrial Property Information and Training (INPIT), under the Act on Special Provisions for Procedures Concerning Industrial Property Rights. In companies, patent searchers often move across from other roles such as research and development, and few are hired as searchers straight from study or mid-career. At patent search firms most staff are hired mid-career, often people who did search work in a company's research and development or intellectual property department. The knowledge and skills needed fall into four broad groups: (1) search skills, (2) intellectual property skills, (3) technical and business skills and (4) communication skills. Search skills cover choosing and using intellectual property databases and search tools and writing search queries. Intellectual property skills cover knowledge of intellectual property law and using it to interpret and judge search results. Technical and business skills relate to the technology being searched and the businesses that use it. Communication skills mean talking with the researchers and engineers who request a search, understanding exactly what they need it for and making sure the right search is done. Based on this knowledge and these skills, a searcher must be able to choose an effective search method for each purpose and carry out the search themselves.
