ResponsibilitiesJMProject managerCoordinates the language workNamedYour counselDirects the filingFiling
Our technical translation services cover engineering specifications, plans, datasheets, and manuals. For a patent assignment, the team reviews component names, measurement units, and drawing references against the supplied technical context.
Software and Interface Materials
Our technical language work also covers software interfaces and documentation. The project manager matches the language team to the subject and records the approved terms for the application and its supporting files.
Biotechnology and Research Documents
Our biotechnology translation service covers related scientific materials. Patent descriptions, research records, and technical references receive a defined language scope. Counsel retains approval of claim wording and the submission package.
Translation Risks That Affect Patent Projects
Legal, research, procurement
A patent assignment requires more than readable prose. Your legal team needs the translated claim to preserve the source wording. Researchers need the same technical term throughout the description. Procurement needs a defined document set, price, and delivery agreement.
The translation brief
Those needs meet in the translation brief. An application prepared for a patent office differs from a passage translated for an internal prior art assessment. Treating both as the same assignment creates uncertainty about completeness, review, and certification.
Version control
Source revisions require clear version control. A revised claim set and an earlier description must not become an accidental final package. Your project manager needs the approved source version and clear instructions about later amendments.
Separate responsibilities
Our patent translation services address the language work within that brief. They do not replace patent drafting, a freedom-to-operate opinion, or representation before a patent office. Keeping those responsibilities separate gives each reviewer a clear decision to make.
Align your legal, research, and procurement teams before translation begins.
The intended use determines which documents belong in the assignment. Our patent application translation service covers the language work on applications and related records. Identify each file’s purpose before combining it with the rest of the package.
Language coverage includes English, Chinese, Japanese, Korean, German, French, Spanish, and Arabic. The assignment confirms the source and target pair for each document. Your technical field and required delivery date also determine the staffing plan.

Applications, Claims, and Priority Documents
Application work includes the description, claims, abstract, and text in drawings. Priority documents need their own scope and receiving-office instructions. A translated abstract alone is a different deliverable from a complete application.
The project brief distinguishes original claims from amendments. It also identifies the version your counsel intends to file. Related applications might share technical passages while differing in claim wording. Each version therefore needs its own source reference.

Prior Art and Technical Research
Prior art translation gives your researchers and attorneys access to documents in another language. The assignment might cover a complete publication or selected passages. Its purpose is to communicate the source material for your team’s assessment.
Provide the relevant pages, publication references, and technical questions. Include enough context to make each excerpt clear. Counsel decides whether the legal analysis requires a broader translation.
Supporting records often extend beyond the patent itself. Our technical translation services cover research papers, engineering specifications, and technical reports. For biotechnology applications, our biotechnology translation service addresses the related scientific document set.

Prosecution and Litigation Materials
Office actions, responses, and prosecution correspondence document the exchange with a patent office. Litigation assignments include the patent documents and supporting legal materials your counsel selects.
Document identifiers matter here. Your team needs to distinguish the application under examination from related publications and earlier versions. The brief should identify the case or application reference, intended reader, and required output.

Patent translation needs both technical understanding and close attention to the source. Our assignment process matches the language team to the subject. A second linguist reviews the translation rather than leaving the translator to assess the work alone.
Independent review gives the assignment a separate linguistic check before delivery. Your counsel’s legal assessment serves a different purpose.

ISO 17100:2015 and the Review Scope
ISO 17100:2015 names translation-service requirements for resources, processes, and delivery. Our assignment includes a translator and a separate linguistic reviewer. The project proposal identifies that language review alongside counsel’s legal assessment. Credential documentation is available through our Trust Center.
Review Brief
Your review brief identifies the passages that need closer examination. Review points include:
Claim wording.
Measurement units.
Chemical names.
Drawing references.
Readable prose alone does not establish that these details match the source.

Translation memoryReference only

Consistent Terms Across a Patent Family
Your approved terminology gives the translator a reference for the invention. Existing translations, glossaries, and technical explanations provide useful context. Include the material your legal and research teams have accepted, with its version and status.
A patent family contains related applications for the same invention. Shared terminology matters, although the documents are not always identical. A changed claim must receive review on its own terms.
Translation memory stores previously translated segments for reuse. It is a reference asset, not evidence that an earlier passage suits a new application. Our technical translation work uses translation memory for consistency. Your patent brief should identify the approved material and any limits on reuse.
When several departments suggest different terms, nominate a decision owner. That person resolves the terminology question before it reaches the filing package. The translator needs one approved answer, together with the context behind it.

Checks for Numbers, References, and Revisions
The source supplies the technical facts. Translation should preserve them without silently correcting the invention or rewriting the claim. Your review instructions should cover numbers, units, claim references, and text associated with drawings.
For example, a component reference in a translated paragraph must still refer to the intended drawing element. An amended claim must not retain an obsolete reference simply because an earlier translation used it.
Agree on the required final format before work starts. Text translation and drawing preparation are different tasks. Editable files make the layout requirements easier to assess than a scan with text embedded in an image.
Patent Office Requirements and Certification
The receiving office determines its language and submission requirements. Our patent translation brief follows the instructions your counsel provides for that destination. There is no single certificate or language package that fits every filing route.
Patent Cooperation TreatyRule 49.5
National Phase Translation Under the PCT
The Patent Cooperation Treaty (PCT) provides an international application route. Under PCT Rule 49.2 and Rule 49.5, a required national phase translation must use an official language of the designated office. Rule 49.2 also addresses offices with several official languages.
Rule 49.5(a) says the translation shall contain the description, claims, any text matter of the drawings, and the abstract. Requirements for amended claims depend on the designated office. Rule 49.5(d) specifies how to furnish translated text in drawings.
The practical assignment therefore includes more than a list of languages. Counsel needs to identify the designated office, relevant claim version, and drawing-text requirements. Those instructions determine the files and layout work to price.
European Patent ConventionRule 71(3)
Claims Translations Before European Patent Grant
The European Patent Office (EPO) has a specific pre-grant translation step. Under European Patent Convention Rule 71(3), the Examining Division shall invite the applicant to complete specified actions within a four-month period. These include filing claims translations in the two official EPO languages other than the language of the proceedings.
Counsel supplies the communicated text and the relevant filing instructions. The translation assignment needs that claim set, rather than a working draft from an earlier examination stage. Your legal team owns the statutory deadline and confirms the submission requirements.
Certified translationSigned statement
Certification for the Intended Submission
Certified patent translation includes a signed statement about the translation’s accuracy and completeness. Day Translations provides certified translation. Certification does not establish patentability or guarantee acceptance by a particular office.
Supply the recipient’s written requirements when certification forms part of the assignment. Those instructions determine the required statement and signatory. A sworn translation or notarized document is a separate requirement and needs separate assessment.
CostSupplied filesDEENLanguage pairTechnical subjectDocument lengthRequested timingFormat and extentComplete applicationWith drawing textShort extractFor research
Patent translation cost depends on the language pair, technical subject, document length, and requested timing. The format and extent of the assignment also matter. A complete application with drawing text differs from a short extract for research.
We assess the supplied files to price the work. Your procurement team should compare estimates against the same document set and deliverables. A lower figure for fewer pages or a different review requirement is not a like-for-like comparison.
What the Project Price Includes
Define translation, review, required certification, and output format in the estimate. Specify any drawing-text preparation separately. This gives the budget owner a record of the work being purchased.
For recurring patent translation, identify the related applications and target languages together. Existing approved translations and terminology are relevant to planning. They do not establish an automatic discount or remove the need to review changed text.
Your requested date also needs context. Include the counsel review period and filing deadline alongside the translation delivery date. The language team needs time for review, rather than an assumption that translation ends at the filing deadline.

Source Changes and Additional Work
Changes after pricing need a fresh assessment of the affected work. A new claim set might also change the description, references, or drawing labels. Tell the project manager which files replace the earlier source.
Before authorizing additional work, settle the revised document set, price, and timing. Avoid mixing a translation of the old file with amendments supplied in a separate message. A single approved source version gives everyone the same starting point.

Our Patent Translation Process
Your project manager coordinates the assignment from the initial brief through delivery. Our technical translation process includes project analysis, translator selection, translation, review, final quality checks, and delivery. For a patent assignment, the following responsibilities belong in that plan.
Set the Document Set and Submission Instructions
Your team supplies the files, source and target languages, technical subject, and intended use. Counsel adds the receiving-office instructions and relevant claim version. Procurement identifies the budget owner and approval requirements.
The project manager assesses the assignment and establishes the price and delivery plan. Include the expected output format and any certification requirement at this stage. Missing instructions need resolution before they become assumptions in the translation.
Match the Language Team to the Technical Subject
The assignment identifies the field and the expertise the documents require. Our project manager selects the translation team for that subject and language pair.
Your research or legal contact supplies approved terms and reference material. Where the source leaves a technical point unclear, that contact provides the authoritative explanation. Translation must preserve the intended meaning without adding unsupported detail.
Translate, Review, and Resolve Queries
The translator prepares the agreed text. A second linguist reviews the translation, and the team performs final quality checks. Your designated contact resolves source questions and terminology decisions that need client input.
Keep legal amendments separate from linguistic corrections. If counsel changes the invention’s wording during review, identify the new source and its status. That distinction prevents an editorial preference from becoming an undocumented source revision.
Deliver for Your Team’s Final Review
Our team delivers the translated document in the agreed format. Your legal or research reviewer assesses it for the intended use. Counsel handles the filing decision and submission.
For related assignments, retain the final source and target versions together. Mark which translation your team approved and when the source changed. Those records provide useful context for the next application or prosecution response.
Discuss review responsibilities and delivery planning for recurring assignments.
Confidentiality requirements belong in the brief before unpublished documents change hands. A non-disclosure agreement (NDA) is available on request. Your procurement and legal teams should settle the applicable confidentiality terms before sharing sensitive technical records.
File Transfer, Access, and Retention
Our Trust Center provides a route for organizations to obtain security documentation. Available materials include a security overview and data processing agreement. Your vendor-risk team reviews the relevant documents against its requirements.
Specify any restrictions on access, transfer, storage, and retention in the project requirements. Use an agreed transfer method for unpublished applications. A confidentiality agreement and a file-transfer arrangement serve different purposes; both need attention.
AI and Machine Translation Permissions
Artificial intelligence (AI) and machine translation introduce questions about document handling as well as language quality. Our patent translation work requires professional post-editing when machine translation forms part of the assignment.
Set any restrictions on automated processing before work starts. Procurement needs to assess the proposed tools and contractual terms, including retention and use of submitted data. A fluent machine-generated draft does not replace review of the patent’s technical meaning.

Patent Translation Services FAQs
Compliance, credentials, turnaround, and cost — answered before you ask.
No. Copies are sufficient for the translation assessment. Legible scans or photographs provide a starting point; editable source files are preferable when the assignment includes formatting. Keep the source version identifiable, and use the agreed transfer route for confidential material.
A description explains the invention, while claims define the protection sought. They serve different purposes within the application. A translation assessment needs both when both belong in the assignment. Your counsel decides the legal wording and the relationship between the claims and disclosure.
Not always. PCT Rule 49.2 says no translation may be required when an application already uses one of the designated office’s several official languages. An exception applies when national law prescribes a particular official language for foreign applicants. Counsel checks which provision applies to your filing.
Not always. Under PCT Rule 49.5(a-bis), the office shall not require translation when the listing meets Rule 12.1(d) and its language-dependent free text uses an accepted language. An office that supplies published listings to database providers may require an English translation if that free text is not in English.
No. PCT Rule 49.5(f) states that the expression “Fig.” does not require translation into any language. This exception concerns that expression. Other words in a drawing still need assessment against the filing instructions.
Yes. EPC Rule 71(6) addresses requests for reasoned amendments or corrections within the Rule 71(3) period. The Examining Division shall issue a new communication if it consents. Otherwise, it shall resume examination proceedings. Counsel confirms the relevant text before commissioning replacement claims translations.
There is no language to translate in a drawing that contains no text. Preserve the drawing as part of the application package when the filing instructions require it. A drawing with words needs a separate assessment of its text and layout requirements.
No. Certification concerns the accuracy and completeness of the translation. Your attorney still decides whether the document is suitable for the intended legal submission. A certificate does not supply a legal opinion or establish the invention’s patentability.
We accept credit cards, debit cards, PayPal, checks, and bank transfers. Our standard payment arrangement requires payment in advance. Procurement should account for that requirement when planning purchase authorization and the assignment’s start.
