Israel Patent Priority Document Translation: When a Certified Translation Is Needed
Disclaimer: This guide is general information, not Israeli patent advice. Have an Israeli patent representative confirm the route, target language, required document scope, translator statement and deadline for your application.
If you are preparing an Israel patent priority document translation, first identify whether your application is a direct national filing or enters Israel through the Patent Cooperation Treaty (PCT). The translation rules differ. In either route, a translation request is generally separate from filing the Israeli application, and the certified copy of the earlier foreign application is a different document from its translation.
Key takeaways
- For a direct filing, the certified copy of the foreign specification and drawings has its own deadline, generally within 12 months after the Israeli application is filed. An early-examination request can bring that deadline forward.
- For a direct filing, the English text of Regulation 25 says the Registrar may request a translation into an official language. The three-month period runs from the request; confirm the required language against the notice and current rule.
- For a PCT application claiming priority from an application that is neither in English nor Hebrew, Regulation 9 specifies a certified translation into Hebrew or English within three months when the Registrar requires it.
- A certified copy concerns the source document; a certified translation attests to the translation. Neither replaces the other, and a translation alone does not establish entitlement to priority.
Who this guide is for
This country-level guide is for foreign inventors, companies, in-house counsel, patent agents and paralegals preparing an Israeli patent application that relies on an earlier foreign patent application. The source document might be in Chinese, Japanese, Korean, German, French, Arabic or another language; these are examples, not published statistics about Israeli filings. A typical file set includes the foreign specification and drawings, priority details such as the application number and date, a certified priority copy, and—if requested—a translation with a translator certification. This guide is especially useful if you are unsure whether the Israel Patent Office (ILPO) wants the source copy, a translation, or both, or if a Registrar’s notice has started a response period.
This article is limited to foreign patent priority documents and translator certificates. It does not cover trademark priority, the full patent-filing process or patent-agent selection. For broader context, see Israel patent and trademark translation requirements.
First identify the route: direct filing or PCT
Patent and priority-document requirements in Israel are set nationally. For this question, the practical distinction is the filing route, the source language of the earlier application and the wording of the Registrar’s request.
| Route | When a priority-document translation may be needed | What the rule says about language and certification |
|---|---|---|
| Direct national filing, including a Paris Convention filing | Regulation 25 permits the Registrar to request a translation. The three-month response period runs from the request, not automatically from the foreign filing date or the Israeli filing date. | The English WIPO Lex text says the translation must be into an official language and satisfactory to the Registrar. It does not prescribe one universal translator certificate or notary format. |
| PCT application entering Israel and claiming priority | Regulation 9 applies if the earlier application was not prepared in English or Hebrew. The translation is due within three months when the Registrar requires it. | The regulation expressly specifies a certified translation into Hebrew or English. |
These route differences appear in the Israel Patent Regulations, including Regulations 24–26, and the separate PCT application regulations, including Regulation 9. The Israel chapter of the PCT Applicant’s Guide gives current national-phase context. Keep the PCT international application’s own translation requirements separate from translation of its earlier priority document.
How to prepare the priority file
- Ask your patent representative to identify the route. Establish whether the Israeli filing is direct or a PCT national-phase entry, and identify each earlier application supporting the priority claim. With multiple priority applications, different parts of the later invention may depend on different earlier filings.
- Request the correct source copy. For a direct filing, Regulation 24 refers to a certified copy of the foreign specification and accompanying drawings. Obtain it from the authority that received the earlier application, or ask your representative whether an accepted electronic document-access route applies. A search result or ordinary download is not automatically the certified copy required for the file.
- Check whether a translation has actually been requested. Keep the ILPO communication with the application record. Note its date, target language, document scope and response period. If it requests the complete specification, an abstract-only translation may not answer it. If it requests particular passages, have your representative confirm the scope before translation begins.
- Give the translator the complete source material. Provide a legible copy of the priority specification and drawings, including figure labels, page numbers and any available corresponding English or Hebrew version. The translation should preserve claim numbering, paragraph references, drawing labels and cross-references so the examiner and representative can compare the texts.
- Keep the copy and translation as separate deliverables. The foreign patent authority’s certified copy concerns the source document. The translator’s certificate or statement concerns the accuracy and completeness of the translation. A stamp on one does not certify the other.
- Have the Israeli representative check the submission. Ask them to confirm the target language, whether the translator statement meets the request, whether the full document is required and how to file the response. Save the submitted translation, source version, notice and filing receipt together.
Keep the different deadlines on separate calendar entries
For a direct national filing, the priority timetable is separate from the translation timetable. Section 10 of the Patents Law generally requires the Israeli application to be filed within 12 months of the earlier application and the priority claim to be made no later than two months after the Israeli filing. It also requires a certified copy from the competent authority at the time set by regulation. See section 10 of Israel’s Patents Law.
| Clock | What it concerns | Practical action |
|---|---|---|
| 12 months from the earlier filing | Direct-route window to file the Israeli application and claim priority, subject to the law’s conditions. | Have patent counsel calendar this before arranging translation. |
| Two months from the Israeli filing | Direct-route deadline to make the priority claim under section 10. | Confirm the claim details are in the application record. |
| 12 months from the Israeli filing | Regulation 24 deadline for the direct-route certified copy of the foreign specification and drawings. | If requesting early examination before this period ends, file the copy with that request. |
| Three months after the Registrar requests it | Translation response under Regulation 25 for a direct filing, or Regulation 9 for a qualifying PCT priority document. | Use the date and scope stated in the official communication. Ask counsel to calculate the exact due date. |
| A separate three months after request | Under Regulation 26, the Registrar may separately require proof that the inventions in the foreign and Israeli applications are substantially identical. | Ask counsel to address this as a legal comparison, not as a translation certificate. |
The counterintuitive point is that the source copy can have a filing-based deadline while the translation may be requested later. These are separate requirements with separate triggers. A PCT national-phase entry has another clock: the WIPO Israel chapter gives 30 months from the priority date for entry. That deadline and any translation of the international application itself are separate from a request to translate the earlier priority document.
Which language and what translator certificate?
For a PCT priority document, Regulation 9 is comparatively clear: if the earlier application was not in English or Hebrew, it specifies a certified translation into Hebrew or English when the Registrar requires one. The PCT application can already be in English and still have a non-English priority document. The international application does not silently translate the earlier filing.
For a direct national filing, the English WIPO Lex transcription of Regulation 25 uses the phrase official language. Do not assume the required target language from general practice or from the language of the later application. Ask your Israeli patent representative to check the current Hebrew rule and the exact ILPO communication, especially before commissioning an English-only translation.
Regulation 9 uses the term certified translation, but the cited English text does not provide a universal certificate template. Regulation 25 asks for a translation satisfactory to the Registrar and likewise does not set one translator credential or certificate wording. A useful translation certificate identifies the source and target languages, the source document and the translator or responsible company, and includes a signed, dated statement that the translation is complete and accurate. Treat this as a verification record, not a substitute for checking the specific request.
The cited priority-document provisions do not impose a blanket notarial translation requirement. Notarization, a sworn statement and a translator’s accuracy certificate are different services. Before paying for notarization, ask your representative whether the route or notice calls for it. For a short overview of the general distinction, see certified versus notarized translation. For the signatory information CertOf includes with its own certification, see who signs CertOf’s certification.
Israel’s filing practice, timing and cost
ILPO’s 2025 annual technical report to WIPO says that over 98% of national patent applications and all PCT applications are filed in English. It also reports that over 99% of national applications are filed online. These figures help explain the English-forward, document-based filing environment, but they do not decide the required target language for a direct-route priority translation. For that, check Regulation 25 and the file-specific notice.
The practical wait can come from two different places: obtaining the certified copy from the authority that received the earlier application, and translating the technical specification after an ILPO request. The public filing figures do not provide an average turnaround for priority translations, translation rejection rate or market price. Translation is a commercial quote rather than an ILPO translation tariff; ask for a written estimate based on page count, language pair, claims, drawings and certificate scope.
For PCT files, WIPO PATENTSCOPE can help locate the published international record. A visible record does not itself prove that ILPO received or accepted the certified priority copy required in your case. Do not assume that mailing a translation to Jerusalem is sufficient; have your representative confirm the filing channel and retain the receipt. If an in-person visit is actually needed, use the separate Israel Patent Office location and access page for that logistics question.
Practical signals for applicants
There is little public first-person information that can establish a typical ILPO priority-translation wait or a universally accepted certificate format. Generic translation-company reviews cannot determine what a particular Registrar’s request requires. The practical risk visible in the rules is deadline confusion: the certified-copy deadline is tied to the filing, while the translation period is tied to a later request. Record each notice date and send it promptly to your patent representative and translator.
Secure the certified source copy early, but scope and commission a translation against the actual request when possible. If another publication in the patent family is available in English, do not assume it is identical to the earlier filing. Have your representative compare the versions and confirm whether ILPO will accept it for the requested purpose.
Commercial translation providers in Israel
The following comparison summarizes public service descriptions; it is not a recommendation or ILPO endorsement. A patent-translation page or customer review cannot establish that a certificate will satisfy a particular request. Ask about your technical field, language direction, confidentiality, claim and figure alignment, revisions, delivery date and the certificate wording your patent representative requests.
| Provider | Publicly stated signal | What to verify for an ILPO priority document |
|---|---|---|
| iTrex Language Services | Its Israel technical-translation page advertises patents, specifications and engineering drawings, lists more than 120 languages, and provides an Israel telephone number: +972 54-295-2659. | Confirm your source-to-target pair and patent field, and ask whether it can provide the exact signed certification your representative approves. Its public page does not establish ILPO acceptance of a certificate. |
| Byron patent translation | Its patent-translation page advertises patent specifications, charts and related materials. It lists a main branch at HaYekev 5, Srigim, telephone +972 77-343-5395, and a language menu that includes Chinese, Japanese, Korean and German. | Ask whether the requested language direction and technical domain are available, whether the service covers the full specification and drawing labels, and whether a translator declaration is provided. Add notarization only if your representative says it is required. |
These businesses provide translation services, not patent representation. CertOf is not an Israeli patent agent and does not decide priority entitlement, advise on Israeli patent law or file with ILPO. Where the language pair and technical subject are within its service scope, CertOf can provide document translation and translation certification. See the service overview for certified translation of patent documents to English.
Public resources, verification and complaints
| Resource | Use it for | Boundary |
|---|---|---|
| Israel Patent Office (ILPO) | The official patent file, examiner or Registrar communications, and the instructions for the specific response. | One accepted translation does not create a universal certificate template for every route. |
| WIPO Lex and the WIPO PCT Applicant’s Guide | Reading published rule text and checking national-phase guidance for a PCT filing. | For a direct-route language question, ask Israeli counsel to confirm the controlling text and notice. |
| WIPO PATENTSCOPE | Locating a published PCT application and related public record information. | A public record is not automatically a certified priority copy lodged with ILPO. |
| Israel Ministry of Justice patent-attorney register | Checking a patent attorney’s credentials when you need legal representation. | This is an attorney register, not a directory of approved patent translators. |
The ILPO complaint service for patent attorneys concerns professional conduct by registered patent attorneys; it is not a translator-licensing or translation-quality certification route. If the concern is about a representative, use the government’s complaint service for patent attorneys. If a translation deadline is approaching, protect the filing deadline separately while addressing a service dispute. The cited rules do not establish an ILPO-approved list of commercial patent translators, so treat claims of official approval as something to verify with your representative.
Common mistakes to avoid
- Waiting for a translation before filing. Do not let an assumption about translation make you miss the separate priority filing window. Have counsel confirm what must be filed now and what may follow.
- Sending only a certified copy. It may establish the source copy’s official status, but it does not certify an accompanying translation.
- Translating automatically into Hebrew. PCT Regulation 9 specifies Hebrew or English. For a direct application, confirm the target language in the current rule and notice.
- Ordering notarization by default. The cited regulations do not set a blanket notary rule for these priority translations. Confirm before purchasing that service.
- Treating translation as proof of priority. Translation supports comparison. It does not establish that the Israeli application was timely, that the priority claim was correctly made or that the inventions are substantially identical.
- Using a translation that cannot be compared. Missing claim numbers, paragraph references or drawing labels can make an otherwise fluent translation difficult to check. See CertOf’s note on accuracy and verifiable document reconstruction.
Frequently asked questions
Do all foreign priority documents need to be translated when I file a patent in Israel?
No. The cited rules do not make every priority-document translation due automatically on the Israeli filing date. For a direct filing, a translation may be requested under Regulation 25. For a PCT priority document that is neither English nor Hebrew, Regulation 9 sets a certified-translation requirement when the Registrar requires it. The certified source copy has its own deadline.
Is a certified priority copy the same as a certified translation?
No. The certified copy comes from the relevant patent authority and concerns the authenticity of the earlier specification and drawings. A translator’s certification concerns the language conversion. A file may need both.
When does the three-month translation deadline start?
The direct-route rule runs three months from the date the Registrar requests the translation. The PCT rule also sets a three-month period when the Registrar requires it. Record the date on the official communication and ask counsel to calculate the exact due date and submission method.
What language should I use for the translated priority document?
For PCT Regulation 9, the text specifies Hebrew or English. For the direct route, the WIPO Lex English text of Regulation 25 uses official language. Ask your Israeli representative to confirm the target language for the particular notice, especially before commissioning an English-only translation.
Does ILPO require a sworn or notarized translator?
The cited provisions do not state a blanket sworn-translator or notary requirement for priority documents. PCT Regulation 9 does require a certified translation. Confirm what proof of certification the notice requires before paying for notarization or an oath.
If my PCT application is in English, do I still need to translate a non-English priority document?
Possibly. The PCT application and the earlier priority application are separate documents. If the earlier application was neither English nor Hebrew, Regulation 9 allows the Registrar to require a certified translation into English or Hebrew even when the international application is in English.
Does an accepted translation prove that I am entitled to the earlier priority date?
No. The priority claim, filing and copy deadlines, entitlement to claim priority, and substantial-identity question remain separate. Translation helps the Registrar compare documents; your patent representative must assess the legal conditions.
Prepare the translation package
If you receive an ILPO translation request, upload the complete priority file and the notice through the CertOf translation portal, or contact CertOf about language and technical scope. Include the target language, response deadline and any certificate wording your Israeli patent representative requires. CertOf can confirm its translation scope, prepare the document and provide its supported translator certification; it cannot determine priority rights, give Israeli patent advice or submit the response to ILPO. Before filing, have your representative verify the translation’s scope, language and certificate against the notice.
