Patent Translation Services
We translate patent applications, granted patents, office actions, and prior art for US filings and PCT national phase entries, with claims handled at the level of rigor that claim construction demands. Every project pairs a subject-matter translator with an independent reviser who reads the claims the way an examiner will.
One source term, one English rendering, enforced across claims, specification, and drawings, because a synonym introduced in claim 9 can hand an infringer their argument.
We schedule around the 30-month PCT clock and USPTO office action dates, with certified translations of priority documents delivered before your paralegal asks twice.
Unfiled applications are trade secrets until the filing receipt exists. NDA first, encrypted transfer, restricted team, no machine translation engines that retain your text.
A Patent Is Won or Lost on Single Words
No other technical document concentrates so much value in so few words. The claims of a patent define the boundary of a legal monopoly, and litigation over that boundary routinely turns on the meaning of one term: whether "resilient member" covers a rigid spring, whether "about 100°C" reaches 95°C, whether "comprising" left the door open to added elements. Professional patent translation services exist because that same scrutiny lands, undiminished, on every translated word. When a US patent claims priority from a Japanese application, or a PCT application drafted in German enters examination, the translation is not a courtesy copy. It is the text the law will read.
The doctrine of equivalents gives translated wording a second edge. Courts may extend claim scope to insubstantial variations, but prosecution history and precise claim language set the limits of that extension. A translator who narrows a term without noticing has quietly narrowed what the doctrine can recover. Techniwords has translated patent documentation for 15 years, for filing companies, in-house counsel, and the law firms that represent them, and the discipline of this work shapes everything else on this page. It is also why patent projects run through a dedicated workflow, separate from the forty other technical document types we cover.
Claims: Controlled Literality, Not Elegant Prose
Good patent translation reads strangely to anyone trained on marketing copy. Claims are translated with controlled literality: the sentence structure tracks the source as closely as target grammar allows, terms repeat exactly as often as they repeat in the original, and no variation is introduced for style. If the Japanese application uses one word for "fastening portion" eleven times, the English claims use one term eleven times. Antecedent basis must survive: every "said flange" and "the second electrode" has to trace back to its first introduction, in the same words.
Transitional phrases get particular care because US practice assigns them fixed legal meanings. "Comprising" is open-ended, "consisting of" is closed, "consisting essentially of" sits deliberately between them, and source-language constructions must be mapped onto the correct one rather than the prettiest one. The same goes for claim-internal logic: "at least one", "a plurality of", "operatively connected". Our translators annotate genuinely ambiguous source constructions instead of resolving them silently, so your patent attorney decides how the ambiguity should fall. That division of labor is deliberate. We supply linguistic precision; counsel supplies claim strategy.
USPTO Requirements: English Text and Certified Translations
The USPTO requires application documents in English under 37 CFR 1.52, and when an application claims foreign priority, examiners or proceedings can require a certified English translation of the priority document, with certification requirements set out in the rules under 37 CFR 1.55. Interference and derivation proceedings, IPR petitions, and litigation all generate the same need: a translation plus a signed statement of its accuracy that will withstand challenge by an opposing party's own translator.
We produce these regularly. Each certified patent translation carries a statement identifying the translator, the documents, and the language pair, executed under our certified technical translation service. The underlying quality mechanism is our ISO 17100-compliant process, translation by a specialist and full independent revision, which matters here more than anywhere: a certification is only as strong as the translation behind it, and opposing counsel will hunt for the weak sentence.
An error in translation can shrink your patent permanently. In several major jurisdictions, third parties may rely on a narrower translated text even where the original was broader, and corrections cannot always restore what careless wording gave away. Under the European Patent Convention, Article 70 lets contracting states treat the translation as authentic where it confers narrower protection. The cheap translation is the most expensive document in the file.
PCT National Phase: Working Against the 30-Month Clock
Most patent application translation is scheduled by treaty. A PCT application must enter the national phase within 30 months of the priority date in the United States, China, and Japan, and 31 months at the European Patent Office, with the translation due at entry or within a short grace window. Miss it and the application dies in that jurisdiction. The practical consequence: translation orders arrive in clusters at months 28 and 29, and an agency serving patent clients has to deliver quality on that compressed rhythm.
| Route | Deadline from priority date | Translation requirement |
|---|---|---|
| US national phase (USPTO) | 30 months | English translation of the international application |
| European regional phase (EPO) | 31 months | English, French, or German text for examination |
| Japan (JPO) | 30 months | Japanese translation, short extension available |
| China (CNIPA) | 30 months | Chinese translation, grace period with fee |
We plan backward from the entry date, not forward from the order date. For a 12,000-word specification entering the US at month 29, that means locking terminology in the first 48 hours, translating claims and abstract first for counsel's early review, and delivering the full text with revision complete at least a week before filing so the attorney has genuine review time rather than a formality.
Foreign Prior Art: Reading the References That Threaten You
The second stream of patent work flows the other way: into English, from documents that were never yours. Examiners cite Japanese laid-open applications, German utility models, and Chinese publications against US applications, and freedom-to-operate studies surface the same material. A first-pass machine rendering may tell counsel which references matter. The references that matter then need human translation, because an invalidity argument built on a garbled paragraph collapses at deposition.
Japanese prior art leads this category by volume, and our Japanese technical translation team has handled kokai publications across electronics, materials, and mechanical arts for years. German references, especially older utility models with pre-war terminology, go to our German engineering translators, who read Fachsprache that modern dictionaries have forgotten. One recent engagement gives the flavor: a law firm defending an inter partes review needed 27 Japanese references translated in three weeks, with certifications for the exhibits actually filed. Two translators, one glossary keyed to the challenged claims, staggered delivery ordered by the firm's brief schedule. The petition survived, and the firm has sent every Japanese reference since.
Beyond the Claims: Specifications, Drawings, and Office Actions
A patent file is bigger than its claims. The specification teaches the invention and feeds claim construction; we translate it under the same terminology controls, since courts read claims in light of it. Drawings carry reference numerals and brief labels that must match the specification exactly, work that overlaps with translating engineering drawings, where our team already lives. Office actions and examiner citations need fast, accurate turnaround during prosecution, because response deadlines at the USPTO and foreign offices do not stretch for language.
Patent projects also border ordinary engineering documentation. The invention disclosure often quotes technical specifications and internal test data, and companies commercializing a patented product frequently need supporting materials in the same terminology, from regulatory files to publications. Clients preparing FDA or international submissions coordinate patent language with regulatory submission translation so the same device is described the same way in both files, and marketing teams borrow the settled vocabulary when we handle their technical white papers. Terminology continuity across that whole family of documents is a quiet asset: it means no competitor ever finds two conflicting descriptions of your own invention in your own paper trail.
Litigation and Licensing: Translating the Other Side's Patents
Not every patent we translate belongs to the client who sends it. Litigation teams need the asserted foreign patent, its file wrapper, and the amendments made during prosecution abroad, because arguments a patentee made to the Japanese or German examiner can constrain what their US counsel may argue now. Licensing negotiations need the counterpart's portfolio in English before anyone prices a cross-license. And competitive intelligence groups track rivals' foreign filings as an early signal of product direction, eighteen months before any launch.
This work has its own requirements. File wrappers are conversational documents, examiner objections and applicant responses trading arguments across years, and the translation must keep each party's voice and each argument's exact scope. Dates matter to the day, since priority chains and intervening art turn on them. And volume estimates are treacherous: a modest-looking German opposition file can run 400 pages once annexes are counted. We quote from the actual page inventory, never from the docket description, and we tell you which documents are boilerplate that can wait.
For portfolio-scale jobs, licensing reviews covering dozens of families, we offer a two-tier approach: summary translations of every family member for triage, then full rigorous translation of the members counsel shortlists. Clients consistently spend less this way, and the money lands on the patents that actually matter to the deal.
Who Translates Your Patents
Patent translation demands a double profile. The translator must command the technical field, because a claim about semiconductor gate structures cannot be translated by someone who has never read one, and must also know patent conventions, because technical fluency without claim discipline produces readable text with legal holes. Our patent team is built from certified translators with engineering and science backgrounds who work exclusively in their fields: electronics and semiconductors, mechanical systems, chemistry and materials, medical technology. Work for electronics and semiconductor companies makes up the largest single share, reflecting where cross-border filing volume actually is.
Every patent passes independent revision by a second qualified specialist, with the claims checked term by term against the terminology table before anything else is read. Techniwords is a member of the American Translators Association and GALA, and our project managers, based in Texas and covering every US time zone, are used to working directly with paralegals and docketing systems, confirming deadlines in writing and delivering in the file formats your firm's tools expect.
Confidentiality Before Filing
An unfiled patent application is a trade secret with a filing date riding on it. Premature disclosure can start clocks under 35 U.S.C. 102 and destroy foreign filing rights in absolute-novelty jurisdictions. Our handling assumes that stake on every pre-filing project: NDAs signed before transfer, files moved over encrypted channels, access limited to the named translator, reviser, and project manager, and no use of any machine translation service that stores or trains on submitted text. On request we confirm deletion of working files after delivery and provide the access list for your records.
The same discipline covers due diligence and litigation support, where the existence of the project is itself confidential. If your matter requires conflict screening, we run it before staffing, the same way your firm would.
Patent Translation: What Counsel and Inventors Ask Us
Do you provide certified translations accepted by the USPTO?
Yes. We supply English translations of priority documents, foreign applications, and prior art references with a signed certification statement identifying the translator, the documents, and the language pair, in the form US practice expects under the rules governing foreign-language documents. These certifications are used in prosecution, IPR proceedings, and litigation exhibits. The translation itself is produced by a subject-matter specialist and independently revised before certification, because the signature is only as defensible as the text behind it.
Can you meet a PCT national phase deadline that is only weeks away?
Usually, yes. Tell us the entry date and the specification length, and we will confirm feasibility within one business hour. Our standard approach delivers claims and abstract first for attorney review, locks terminology in the first two days, and completes the full revised specification at least a week before filing. A 10,000 to 15,000 word application is comfortable in three to four weeks; tighter windows are possible with a two-translator team under a shared terminology table.
We have a large batch of foreign prior art references. How do you handle volume?
Prior art batches are staffed as a coordinated project: a glossary keyed to your claims is built first, references are prioritized in the order your brief or search report needs them, and delivery is staggered so review starts immediately. Certification is applied selectively, typically only to references you will actually file as exhibits, which keeps costs proportionate. Recent projects have run from five references in a week to 27 Japanese publications in three weeks with filing-ready certifications.
How do you protect an application that has not been filed yet?
We treat unfiled applications as trade secrets. Confidentiality agreements are signed before any file transfer, documents move through encrypted channels, and the project team is limited to the named translator, reviser, and project manager. We never process pre-filing text through machine translation services that retain or train on submissions, and we confirm destruction of working files after delivery on request. Premature disclosure can compromise novelty in absolute-novelty jurisdictions, so our default posture is that nothing about the project is shareable.
Do you work directly with our IP law firm?
Yes, and most of our patent volume runs that way. Project managers coordinate with paralegals and docketing teams, confirm deadlines in writing, and deliver in the formats your tools expect, whether that is Word for further drafting or PDF for exhibits. Where counsel prefers to review terminology, we submit the claim term table for approval before full translation begins. In-house teams sometimes engage us directly and copy outside counsel; either arrangement works, as long as one reviewer owns final terminology decisions.
What does patent translation cost?
Pricing is per source word and varies with the language pair and technical field; Japanese and Chinese patents price differently from German or French, and a biotech specification differs from a mechanical one. Claims are included in the standard rate, not surcharged, because we consider claim rigor the baseline of the service. Certification adds a modest flat fee per document.
