Why Choose Our Patent Translation Services?
DocTranslator translates patent documents with AI and keeps their numbered claims, figures and page layout in place. Because a patent's scope depends on the exact wording of its claims, have a qualified translator or patent attorney review any translation you plan to file.
Below you will find detailed advantages of our service:
File Size Up to 1 GB
Patent files with claims, drawings and prior-art annexes can be uploaded as one document: up to 1 GB or 5,000 pages per file on Pro and Business, and 100 MB or 300 pages on Basic. Within those limits you do not need to split the application, and one with hundreds of pages can be handled in a single process while keeping the translation workflow fast and efficient.
Formatting Preserved
Whether your patents are in PDF, DOCX, TXT, or image formats, the translated result will maintain the exact formatting and layout. Tables, diagrams, and page structures remain consistent across the translated file. This ensures your patent documents are ready for official submission or review without any additional manual adjustments.
108 Languages
With coverage of 108 global languages, you can translate your patent documents for international jurisdictions without barriers. DocTranslator supports widely used languages like English, German, Russian, and Spanish, as well as more specific markets such as Japanese, Korean, and Chinese, ensuring smooth cross-border patent protection.
Translation Accuracy
Patent documents often contain complex terminology and legal phrasing. DocTranslator uses advanced AI technology to translate every section with high precision while preserving the original meaning. Our solution reduces human error and ensures that the translated patents meet legal and technical standards required by international offices.

Frequently Asked Questions
Can a full patent file go through as one PDF?
Yes, as long as it fits your plan. Free stops at 20 pages, enough for a short specification. Basic takes 300 pages and 100 MB, while Pro and Business accept 1 GB and 5,000 pages, room for a prosecution history with every drawing sheet. See how to translate a large patent PDF as one file.
What file formats does DocTranslator support?
DocTranslator supports DOCX (Word), PDF, XLSX (Excel), PPTX (PowerPoint), IDML (InDesign), TXT, JPG, JPEG, PNG, CSV, and JSON files. You can drag and drop files or browse your device to upload them.
How much does it cost to translate documents with AI?
Signing up is free, and on the Free plan every AI translation is paid per document: $0.005 per word, or $1 per page for PDFs and scans, with a $0.99 minimum. A subscription includes AI translation every 30 days: up to 1,000 pages on Basic (from $1.99 a week) and up to 5,000 on Pro ($19.99 a month) and Business ($49.99 a month). All plans include 108 languages and full file format support.
How many languages does DocTranslator support?
DocTranslator supports 108 languages including Spanish, French, German, Chinese (Mandarin and Cantonese), Japanese, Korean, Arabic, Portuguese, Italian, Russian, and many more.
How fast is the AI document translation?
It depends mostly on the document. A short PDF with a text layer comes back sooner than a long scan, because each scanned page has to be recognised (OCR) before it can be translated. There is no setup step before that: you upload the file, choose the two languages, click "Translate" and download the result in its original format and layout.
Does DocTranslator preserve the original document formatting?
Yes, DocTranslator maintains the original language style, formatting, fonts, and layout of your document. The AI ensures accuracy and context while preserving the natural flow of your original document across all supported formats.
Is my document secure when using DocTranslator?
Yes, all communications with DocTranslator are encrypted. Your private documents are handled with discretion, and only authorized personnel can view your files. DocTranslator has robust privacy policies in place.
Can I preview my translation before paying?
Yes, where a preview is available for your language pair. After you upload a file, DocTranslator shows its first page already translated, free of charge, before you pay; for EPUB and HTML files it is the opening section. For a fuller check, the monthly Basic plan starts with a 7-day free trial for up to 30,000 words, or you can pay for a short document on its own, from $0.99.
What's the difference between AI translation and human translation?
AI translation is instant and affordable ($0.005/word on Free, less on Pro, paid per document) and ideal for quick understanding of content. For official purposes like USCIS submissions that require certified and notarized translations, you must use human translation services.
How do I get started with DocTranslator?
Create a free DocTranslator account by signing up with your name, email, and password. Then upload your file (Word, PDF, PowerPoint, etc.), select source and target languages, click "Translate," and download your translated document.
