Patent and IP Document Translation Services in India

Patent translation is among the most technical translation categories, claims drafting, technical drawings labels, the precise scope of independent / dependent claims, prior-art references, and inventor declaration statements all have to be translated with patent-drafting expertise rather than general translation. A mistranslated claim narrows or invalidates the protection scope. SiZA Global routes patent translation to translators with prior patent-drafting experience in the specific technical domain (mechanical, electronics, pharma, biotech, software).

Send the patent application or specification along with the target patent office and deadline; we share the per-word rate, which is typically higher than ordinary translation because of the technical specialisation, the working-day timeline after scope review, and a written quote before any translation begins.

Patent translation for Indian inventors and IP firms filing at the European Patent Office (EPO) uses German, French, or English as the procedural language depending on the EPO division and the filing strategy. EPO published patents (B publications) are typically translated to one of the other two procedural languages for validation in target European countries. The translation must preserve claim language word-for-word; ambiguity in claim translation collapses the priority claim and can void the patent in litigation.

Patent translation for Japan Patent Office (JPO), China National Intellectual Property Administration (CNIPA), and Korean Intellectual Property Office (KIPO) is a specialised category. Each office reads Japanese / Chinese / Korean with strict claim-language conventions; a generic translator who is not specifically experienced with patent prosecution language will produce a translation that is technically correct but legally weaker. We work with patent-specific translator networks for these language pairs.

Common Indian-side IP translation work at SiZA: PCT national-phase entry translations (English to Japanese / Chinese / Korean / German for direct filings); EP-validation translations for patent validation in Germany, France, Italy, Spain after EPO grant; trademark filing translations for WIPO Madrid Protocol member countries; IP licensing agreement translations for cross-border tech-transfer deals; opposition and cancellation proceeding translations for patent and trademark disputes; prior-art search report translations for due-diligence purposes during M&A. Each IP-translation lane has its own format expectation that the receiving IP office reads.

You can't mess with patent and IP documents. A single inconsistent translation of a claim word collapses the priority claim and exposes the inventor to invalidity arguments at the destination IP office. We work with patent-specific translator networks for EPO German / EPO French, JPO Japanese, CNIPA Chinese, KIPO Korean, Rospatent Russian, GCC Arabic, and Latin American Spanish. Inter-city legs use Blue Dart, DHL, FedEx, DTDC Premium, UPS. We do not use Porter, Wefast, Borzo or similar third-party parcel apps for patent files. WhatsApp the patent application or specification and the target IP office; we route through translators with prosecution-language experience for that office and we lock the claim-language glossary with the inventor or counsel before the operative-claim translation starts.
