sentence that changes the answer \u2696\ufe0f<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Council Regulation (EU) No 1260\/2012 separates different translation functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Recital 11 supports machine translation as a way to improve access to patent information. Recital 12 addresses the additional translation required during the transitional period and states:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cSuch translations should not be carried out by automated means.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">The location of that wording matters. It appears in a recital explaining the regulation, while Article 6 sets out the operative transitional translation requirements. An accurate explanation should preserve that distinction rather than invent an article that prohibits every use of AI in patent work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The EPO nevertheless expressly repeats the recital\u2019s instruction in its practical guidance. Businesses should therefore not interpret the absence of an accuracy examination as permission to submit raw machine output. <a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/EN\/TXT\/PDF\/?uri=CELEX%3A32012R1260&amp;utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener\">eur-lex.europa.eu<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The relevant question is not simply whether software touched the document. It is what translation is being supplied, for which purpose, and under which requirement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_must_accompany_the_request_in_2026\"><\/span>What must accompany the request in 2026?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The EPO\u2019s 2026 Unitary Patent Guidelines continue to require a full translation with the request for unitary effect. The language depends on the language of the European proceedings.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Language of proceedings<\/th><th>Required additional translation<\/th><\/tr><\/thead><tbody><tr><td>French<\/td><td>Full specification into English<\/td><\/tr><tr><td>German<\/td><td>Full specification into English<\/td><\/tr><tr><td>English<\/td><td>Full specification into another official EU language<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFull specification\u201d includes the description, claims, and text appearing in drawings. Translating only the claims or supplying a generated summary does not meet that description. The Guidelines also confirm that this additional translation is informational and has no legal effect. <a href=\"https:\/\/www.epo.org\/en\/legal\/guidelines-up\/2026\/section_2_2_7?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener\">epo.org<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An English-language patent therefore cannot use a Korean translation to satisfy this particular requirement. Korean is not an official EU language.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That does not make a Korean version commercially unnecessary. It means that a translation for Korean engineers, executives, or licensing teams serves a separate purpose and needs its own instructions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E2%80%9CNo_legal_effect%E2%80%9D_does_not_mean_%E2%80%9Cno_consequences%E2%80%9D_%F0%9F%94%8D\"><\/span>\u201cNo legal effect\u201d does not mean \u201cno consequences\u201d \ud83d\udd0d<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The informational translation does not become the authoritative patent text merely because it is filed. A mistranslation in that document should not be described as automatically rewriting the granted claims.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its practical influence can still be substantial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consider these illustrative situations\u2014not accounts of customer projects:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A licensing team misunderstands an exclusion.<\/strong><br>An automated version drops a negative expression from a process description. A potential licensee reads the document as covering a technique that the passage actually excludes. Negotiations proceed on a mistaken technical premise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A product team mistakes an option for a requirement.<\/strong><br>A phrase describing an optional component becomes mandatory in translation. Engineers spend time designing around a feature that was not presented as compulsory in that passage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A supplier confuses capability with operating conditions.<\/strong><br>A statement that a device is capable of operating within a range becomes an instruction that it must operate throughout that range. The translation changes the commercial reader\u2019s understanding of performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">None of these examples establishes infringement or claim scope. They show how an informational document can affect expensive decisions before a lawyer is asked to examine the authoritative text.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">A translation does not need to define the legal right to influence the people making decisions about it.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Does_human_editing_make_an_AI_draft_acceptable\"><\/span>Does human editing make an AI draft acceptable?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is where confident marketing claims often outrun the official guidance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cited EPO material does not establish a percentage of human edits, a minimum review time, or a named AI workflow that automatically makes an automated draft acceptable. \u201cReviewed by a person\u201d is therefore not a self-proving compliance statement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A quick fluency check may leave almost every technical error untouched. A reviewer who reads only the target text cannot reliably identify omitted qualifications, changed dependencies, or a missing sentence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the required transitional translation, the prudent commissioning approach is a professionally prepared human translation, with the responsible representative confirming any proposed use of automation. Translation memory, terminology databases, and automated consistency checks should also be distinguished from generating the translation itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The deliverable should make responsibility clear. Who compared it with the complete specification? Who resolved ambiguous terminology? Which source version was used? A vague assurance that the text was \u201cAI-assisted and checked\u201d answers none of those questions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_dispute_creates_a_different_translation_obligation_%F0%9F%9A%A8\"><\/span>A dispute creates a different translation obligation \ud83d\udea8<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Translation duties do not end with registration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Article 4 provides for a full translation at an alleged infringer\u2019s request into an eligible language connected with the location of the alleged infringement or the alleged infringer\u2019s domicile. A competent court can also request a full translation into its language of proceedings. The patent proprietor bears those translation costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The regulation additionally requires consideration, in damages disputes, of whether the alleged infringer lacked knowledge or reasonable grounds to know of infringement before receiving the relevant translation. That is a case-specific consideration, not automatic immunity. Recital 8 also addresses avoiding automated means for dispute translations. <a href=\"https:\/\/www.epo.org\/en\/legal\/up-upc\/2022\/eu20121260.html?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener\">epo.org<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A business should therefore distinguish three budgets: preliminary patent reading, the translation required for registration, and possible dispute-related translation. They have different purposes and should not be purchased under one generic instruction to \u201ctranslate the patent.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Where_automation_can_earn_its_place\"><\/span>Where automation can earn its place<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Machine translation can make an unfamiliar publication easier to screen. An engineer may use it to identify potentially relevant embodiments or decide which documents warrant closer review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The danger is allowing that preliminary output to acquire authority through repeated circulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A downloaded translation becomes an internal briefing. The briefing becomes a slide. The slide becomes the basis for a product decision. By that stage, the uncertainty attached to the original machine output may have disappeared.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A practical internal distinction helps:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Intended use<\/th><th>Appropriate control<\/th><\/tr><\/thead><tbody><tr><td>Initial relevance screening<\/td><td>Identify output as preliminary and retain the source<\/td><\/tr><tr><td>Technical assessment<\/td><td>Verify decisive passages against the original<\/td><\/tr><tr><td>Licensing or commercial review<\/td><td>Use reviewed wording and obtain legal interpretation where needed<\/td><\/tr><tr><td>Required procedural translation<\/td><td>Confirm the applicable translation rules with the representative<\/td><\/tr><tr><td>Korean stakeholder communication<\/td><td>Prepare terminology and detail for the actual readership<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This approach concentrates specialist review where misunderstanding could change a decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Korean_readers_need_the_correct_European_version_too_%F0%9F%8C%90\"><\/span>Korean readers need the correct European version, too \ud83c\udf10<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For overseas companies working with Korean manufacturers, research partners, or investors, the language issue often extends beyond the European filing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Korean patent translation may support a technical evaluation, a licensing discussion, or an internal portfolio review. Those assignments require different levels of detail. A management summary cannot substitute for a complete technical translation, and neither should be confused with a Korean patent application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Version control is particularly important. The EPO\u2019s Guidelines state that a further amended informational translation is not required when claims or the description are changed in subsequent opposition or limitation proceedings. An earlier translation can therefore remain available without reflecting later amendments. <a href=\"https:\/\/www.epo.org\/en\/legal\/guidelines-up\/2026\/section_2_2_7?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener\">epo.org<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before commissioning a Korean version, identify the publication and the specific claim set to be translated. Do not assume that the first translated document found in the file represents the current text.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our Korean-language translation support can be scoped around that practical need: complete specifications for technical review, selected passages for specialist assessment, or clearly identified summaries for business readers. European procedural compliance remains a matter for the responsible patent representative.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_instructions_that_prevent_the_wrong_deliverable\"><\/span>The instructions that prevent the wrong deliverable<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A useful translation brief identifies the document\u2019s role before discussing turnaround time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specify the source publication, relevant amendments, target audience, and whether the assignment is a complete translation or a defined extract. Include existing terminology where it has been approved, but allow the reviewer to flag terms that conflict with the present disclosure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a Korean technical team, ask that claim references, component numbers, formulas, and qualifications remain traceable to the source. For a business audience, request explanations separately so that commentary is not mistaken for translated patent text.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most valuable question at handover is concrete: <strong>Can the reader distinguish what the patent says, what the translator has clarified, and what still requires legal interpretation?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Legal references used: Council Regulation (EU) No 1260\/2012, Recitals 8, 11 and 12 and Articles 4 and 6; EPO Unitary Patent Guidelines 2026, section 2.2.7; and the EPO\u2019s translation FAQ.
