The essay stage of the Benrishi required subjects is a formatting problem as much as a knowledge problem: long legal recitation hides the reasoning a reader needs to find. This guide trains element-mapped, conclusion-first answering across the Patent, Utility Model, Design, and Trademark Acts. Start today by picking one hypothetical, writing the conclusion first, and forcing every following sentence to satisfy exactly one statutory element, anchored to the provision that defines it.
Building a Conclusion-First Structure a Reader Can Extract
Essay answers in the required subjects are read for extractable reasoning. Organize every answer as conclusion first, statutory basis second, then element-by-element application, so each sentence does one identifiable job.
Japanese legal essay convention separates 結論 (conclusion), 根拠 (grounds), and 適用 (application to the facts). A workable template opens with your conclusion and a one-line reason, then devotes one paragraph to each statutory element in the order the statute lists them. Each paragraph cites the provision that defines the element and applies the stem's facts to it. Writing the conclusion first, even provisionally, prevents the drift into lecture-style exposition that application questions punish.
Contrast this with the common alternative: reproduce the legal doctrine, then leap to a conclusion, leaving the reader to infer which facts mattered. To break that habit, take a textbook explanation of a requirement and rewrite it as an answer — same law, but reordered so application sentences dominate. Reuse the identical skeleton across all four required statutes; only the vocabulary and named procedures change. Structure should become automatic so your mental effort goes to substance.
Separating Novelty from Inventive Step in Fact-Based Questions
Novelty (新規性) asks whether one prior disclosure anticipates the claimed invention. Inventive step (進歩性) asks whether a person skilled in the art could easily reach it. Analyze novelty first, then inventive step separately.
These are different questions requiring different reasoning. Novelty compares the claimed invention against a single disclosure: if every element appears in one reference, novelty fails. Inventive step presumes novelty and asks whether combining prior art, or modifying one reference, would be easy for a person skilled in the art — which requires discussing that person's level of skill and motivation. Keep the two stages visibly separate; an answer that merges them usually loses the motivation analysis entirely.
Worked scenario 1: a claim covers a coating apparatus with a spray nozzle plus a temperature sensor; the cited reference describes a coating apparatus with a spray nozzle only. A plausible mistake is rejecting for lack of novelty by silently blending the reference with common knowledge about sensors. The better decision: state that the single reference lacks the sensor, so novelty is satisfied; then assess inventive step — is fitting a temperature sensor to such apparatus an easy design choice for the skilled person, and does a reference suggest it? The distinction matters because each stage demands different evidence and reasoning, and a complete answer shows both.
Responding to a Refusal Notice Without Amending Beyond the Original Disclosure
When a question presents a 拒絶理由通知, any 補正 you propose must stay within the original disclosure's support, and your argument must show where that support sits. An improper amendment defeats even correct substantive reasoning.
Keep the named concepts straight: the notice of reasons for refusal states the examiner's grounds; the applicant responds by amendment (補正) and/or argument. Support comes from what the specification as filed discloses. In an essay, whenever you propose an amendment, name the claim limitation you are changing and point to where the new wording is disclosed or derivable in the original specification. If you argue instead, explain why the claim as written already satisfies the challenged requirement, using the specification's own words.
Worked scenario 2: the refusal attacks 'heat-resistant resin' in claim 1 as insufficiently supported. A plausible mistake: amending to 'fluororesin with a melting point of at least 300°C' — a material and threshold appearing nowhere in the original description. The better decision: restrict to the resin specifically disclosed in the working examples, or defend the broader term by citing how the original description characterizes heat resistance. Why it matters: an amendment reaching beyond the original disclosure is typically disregarded, so examination reverts to the unamended claim — meaning all your careful argument about the new wording counts for nothing.
Routing Each Question to the Right Statute Before You Write
Each required statute has its own protected subject, vocabulary, and procedures. Identify the statute from the stem before writing, then use its terms — confusion, similarity, technical features — rather than a generic rights analysis.
Use the table below as a pre-answer routing step. Patent questions live in technical features, novelty, and inventive step. Utility model questions turn on registration without substantive examination and the technical evaluation consulted before enforcing the right. Design questions turn on the design itself and similarity, with partial designs as a distinct drafting topic. Trademark questions turn on signs, designated goods or services, and likelihood of confusion.
The recurring difficulty is cross-contamination: analyzing a design as if it were an invention, or arguing trademark similarity the way one argues design similarity, produces answers that are legally coherent about the wrong statute. After reading the stem, write the statute's name on your scratch paper and list its two or three signature procedures. That one minute of routing decides whether the whole answer speaks the right language.
| Statute | Central essay question | Procedures to name | Adjacent-concept confusion to avoid |
|---|---|---|---|
| 特許法 Patent Act | Are the technical features novel and inventive? | Refusal appeal, invalidation trial, correction | Merging novelty and inventive step analysis |
| 実用新案法 Utility Model Act | Is the device registered and enforceable? | Registration without substantive examination, technical evaluation request | Importing examination-based patent reasoning |
| 意匠法 Design Act | Is the design registrable and does it conflict? | Partial design applications, refusal appeal, invalidation | Judging a design by technical effect |
| 商標法 Trademark Act | Is the mark confusingly similar in use? | Opposition, non-use cancellation | Judging marks by visual design similarity alone |
Choosing the Right Post-Grant Procedure for the Facts Given
Refusal appeals (拒絶査定不服審判) occur before grant between the applicant and the examiner's decision; invalidation trials (無効審判) occur after grant between interested parties. Match the procedure to the timeline in the stem.
The facts in a procedure question usually contain a timeline, and the timeline determines the answer. Before grant, an applicant who receives a refusal may pursue an appeal against it, with the applicant as the moving party. After grant, the right is attacked through invalidation, where another party files and the patentee responds. Keep the party structure explicit in your answer: who moves, who responds, and what relief each side seeks. Naming the wrong forum misdirects the entire analysis.
Worked scenario 3: you sued on your granted patent and the defendant seeks to have it revoked. A plausible mistake: structuring the answer as a refusal-appeal analysis, which presupposes a pending, ungranted application. The better decision: frame it as an invalidation trial — the defendant as requester, your client defending the patent, and correction of the claim as a defensive possibility within the response. Why it matters: the forum decides who bears the argumentative burden, who participates, and which remedies exist; a correct substantive conclusion inside the wrong procedural frame reads as procedural confusion.
Treating PCT, Madrid, and Hague Questions as Routing Exercises
Foreign-related questions turn on routing, not foreign substantive law: PCT for patent filings, the Madrid system for trademarks, the Hague system for designs. Trace each step's location and Japan's treatment at the national phase.
A useful mental model: no single 'international patent' exists — a PCT international application preserves a filing date and channels applications toward designated offices, which then examine under their own law. The Madrid and Hague systems similarly route trademark and design registrations through international procedures to designated countries. An essay answer scores by naming the correct treaty for the subject, stating what the international step accomplishes and what it does not, and explaining how the procedure lands back in a national or regional phase.
Build this knowledge as diagrams rather than prose: for each treaty, draw one route — home filing, priority claim, international filing, designated offices, national phase — with a one-line label per box saying what that step changes for the applicant. Then test it with stem facts such as a Japanese applicant seeking protection in several countries, and trace each box. Learn what each procedural deadline protects rather than reciting every period; qualitative function is what an essay can actually assess.
A Weekly Practice Cycle with a Five-Point Self-Check Rubric
Run one timed, conclusion-first answer per statute each study week, then score it against the rubric below. Treat rubric scores as learning milestones for structure and application, not as predictions of examination results.
Exercise: take a hypothetical comparing two coating apparatuses for inventive step, or a refusal notice on a trademark application. Write a conclusion-first answer under the time you would realistically allocate to one question. Expected observations from first attempts: statute recitation occupies most of the page, element sentences are missing or merged, and the application section arrives in the final lines. Note which of the five rubric points failed; that failing point becomes the single focus of the next practice answer, one fix at a time.
An adaptable preparation sequence: first pass, build element lists for each of the four statutes and check them against the statutes and the JPO examination guidelines. Second, outline answers only — conclusion and element map, no prose — until routing between statutes and procedures is instant. Third, full timed answers alternating statutes, graded against the rubric, with an error log recording misapplied elements and wrong procedures rather than forgotten law. Finish by rewriting your weakest logged answers and re-testing them. For schedules and administrative requirements, consult the JPO's Benrishi examination pages rather than any summary.
- Conclusion appears in the opening sentences, hedged provisionally if the outcome is genuinely debatable.
- Every body paragraph opens with exactly one statutory element and names the provision defining it.
- Each element is tied to a specific fact in the stem; no analogy runs without a stated limiting assumption.
- Adjacent concepts are separated in order: novelty before inventive step; refusal appeal versus invalidation; design versus trademark similarity.
- Application and reasoning consume the majority of writing time; pure recitation stays minimal.
