ExploreAbout this exam
The 弁理士試験 (Benrishi Exam) is Japan's national examination for becoming a 弁理士 - a patent attorney qualified to represent clients before the Japan Patent Office in patent, utility model, design and trademark matters. It is administered under the jurisdiction of the Japan Patent Office (特許庁), the agency whose website hosts the examination information pages. Candidates are typically law and science graduates, engineers, and IP department staff who need formal standing to draft and prosecute applications, handle trials and appeals, and advise on IP strategy. The exam is notorious for its breadth and depth: it tests the four IP statutes together with related procedural law, treaty and foreign-law knowledge (Paris Convention, PCT, Madrid Protocol, TRIPS and major national systems), attorney ethics and practice regulations, and the ability to write reasoned legal analysis under time pressure. Because the 短答 (short-answer) stage is heavily weighted toward recall and the 論文 (essay) stage toward structured legal argument, preparation normally takes one to three years: build statute-by-statute familiarity, work through past official questions, then practise timed essays and oral explanations. This page is an independent study resource and is not affiliated with, endorsed by, or operated by the Japan Patent Office or any official examining body. Verify all procedural details - schedule, fees, eligibility and pass criteria - against official announcements before relying on them.
What you'll study
About Benrishi Exam preparation
Is this page an official source for the exam?
No. This is an independent study resource and makes no claim of affiliation with the Japan Patent Office or the examining bodies. Use it to organise your study, but confirm every procedural point - dates, fees, eligibility, pass standards - against official announcements before you rely on it.
What does the exam actually test?
Four broad areas: the substantive and procedural law of patents, utility models, designs and trademarks; treaties and foreign law, including the Paris Convention, PCT, Madrid Protocol and major national systems; the 弁理士法 and practice-related regulations; and essay and oral work testing structured legal reasoning rather than recall.
How long does preparation usually take?
Most successful candidates report one to three years of sustained study. A workable sequence is statute-by-statute reading first, then past official questions to expose gaps, then timed essay practice, and finally oral explanation drills where you must defend a conclusion aloud without notes.
What is the hardest part for most candidates?
The essay stage. Short-answer questions reward memorisation, but essays require you to spot the issue, state the applicable provision, apply it to the facts and reach a defensible conclusion within a strict time limit. Candidates who only memorise provisions typically run out of time or write conclusions without reasoning.
Can I retake the exam if I fail?
Retake rules and any limits on the number of attempts are set by official examination regulations, which are outside what this page can confirm. Check the current official examination guidelines for the applicable policy rather than relying on second-hand accounts, since rules have been revised over time.
Should I study the four IP statutes together or one at a time?
Study one statute deeply first to learn the structure of IP reasoning - application, examination, rights, infringement, remedies - then transfer that framework to the others. Treaties are easier once the domestic statutes are solid, because much treaty content is about priority, international filing routes and procedural coordination.
How should I use past exam questions?
Do not read them passively. Answer under time pressure, then mark every question where your reasoning was wrong even if your answer was right. Group errors by statute and topic; recurring clusters reveal which provisions you have not truly understood. Revisit those provisions in the statute text before attempting more questions.
What are the most common failure modes?
Three recurrences: memorising provisions without being able to apply them to new facts; neglecting treaties and the 弁理士法 until late, when they carry substantial weight; and failing to practise writing or speaking under time pressure. Candidates who never simulate exam conditions often know enough but cannot deliver it.
Where can I find official information?
The Japan Patent Office website publishes examination information under its 資格・試験 section, including pages on 弁理士について and 弁理士試験. Treat those pages, and any official announcements they link to, as authoritative; this study page is not a substitute for them.
