How to File a Patent in Israel (2026): PCT National Phase, Deadlines, Fees & Practical Checklist

Understanding how to file a patent in Israel 2026 has become more urgent than ever, as updated ILPO fee schedules took effect on 1 March 2026 and ongoing wartime office-closure measures continue to affect critical deadline calculations. Israel remains one of the world’s most innovation-dense economies, home to thousands of deep-tech startups, a thriving medtech corridor and a mature patent enforcement regime, making national-phase entry a high-priority decision for foreign filers and domestic inventors alike. This guide consolidates every procedural step, deadline, fee and contingency plan into a single actionable resource, designed for startup founders, in-house IP managers and foreign patent counsel preparing PCT national-phase entry or direct filing in Israel during 2026.

Quick TL;DR, Three Facts Every Filer Must Know

• 30-month national-phase deadline. Israel is a strict 30-month PCT country. The deadline runs from the earliest priority date, and missing it can permanently forfeit patent rights in Israel. Early indications suggest that restoration requests are granted only in narrow circumstances.
• ILPO fees updated 1 March 2026. The Israel Patent Office published revised official fees valid as from 1 March 2026, affecting filing fees, additional-claim surcharges and renewal annuities. Filers should budget against the new schedule.
• Wartime office closures may extend deadlines. Under PCT Rule 80.5, where the ILPO is closed on the day a time limit expires, the deadline is automatically extended to the next business day the office is open. Separate ILPO wartime notices may grant further extensions, applicants should check the ILPO PCT department page for the latest guidance and seek local counsel immediately if a deadline is imminent.

1. Overview, Why the Patent Filing Process Israel Demands Attention in 2026

Israel punches well above its weight in global innovation. The country consistently ranks among the top nations for R&D spending as a share of GDP, and its patent system provides strong enforcement tools, including injunctive relief, damages and border measures, that make Israeli patents commercially valuable. For international companies in medtech, cybersecurity, agritech, water technology, software and energy, securing patent protection in Israel is a strategic necessity rather than a formality.

The patent filing process in Israel is administered by the Israel Patent Office (ILPO), a division of the Ministry of Justice. Applications may be filed directly with the ILPO or, more commonly for foreign applicants, by entering the national phase of an existing PCT (Patent Cooperation Treaty) international application. Both routes lead to the same substantive examination, but timing, cost and procedural requirements differ significantly. For a broader perspective on cross-border IP strategy, see our international intellectual property guide.

Patentability Requirements in Israel

Under the Israel Patents Law, 5727-1967, an invention is patentable if it satisfies three core criteria:

• Novelty. The invention must not have been published or publicly known anywhere in the world before the filing or priority date.
• Inventive step (non-obviousness). The invention must not be obvious to a person skilled in the relevant art, given the state of the art at the priority date.
• Industrial applicability. The invention must be capable of being made or used in industry, including agriculture.

Methods of medical treatment are generally excluded from patentability, although pharmaceutical compositions and medical devices are patentable. Software-related inventions may be patentable where they produce a technical effect beyond ordinary computer operation, a nuance that experienced Israel patent counsel can navigate. Understanding why IPR protection matters is essential before committing prosecution resources.

2. PCT National Phase Israel, The Primary Compliance Decision

For the vast majority of foreign applicants, the PCT route is the gateway to Israeli patent protection. The single most important compliance decision is whether, and when, to enter the PCT national phase in Israel. Get this wrong and the application is irretrievably lost.

Israel imposes a strict 30-month deadline from the earliest priority date for national-phase entry. Unlike some jurisdictions that allow 31 months, Israel adheres to the 30-month limit set out in PCT Article 22. The WIPO PCT Applicant’s Guide for Israel, valid as from 1 March 2026, confirms this deadline. There is no automatic grace period beyond the 30th month, and late entry is permitted only through a formal restoration-of-rights request, a remedy that is discretionary and narrowly applied.

The decision tree is straightforward. If the invention has commercial relevance in Israel, whether for market entry, licensing, defensive positioning or investor due diligence, national-phase entry should be calendared early and filed well ahead of the 30-month mark. If the commercial case is uncertain, industry observers expect many filers to use the full 30 months of PCT deferral to reduce cost before committing, but the deadline itself is non-negotiable.

Key Dates Explained, Three Worked Examples

The 30-month clock starts from the earliest priority date, not the PCT international filing date. Three examples illustrate the arithmetic:

• Example 1. Priority date: 15 January 2024. National-phase deadline: 15 July 2026 (30 months later). File at the ILPO on or before 15 July 2026.
• Example 2. Priority date: 1 June 2024. National-phase deadline: 1 December 2026. This applicant has several months of runway remaining in 2026.
• Example 3. Priority date: 1 March 2023. National-phase deadline: 1 September 2025. This deadline has already passed, if national-phase entry was not completed, restoration must be sought immediately (see Section 5 below).

What Must Be Submitted at National-Phase Entry

To validly enter the national phase in Israel, the following documents and actions are required by the 30-month deadline:

• National-phase request form. Filed through the ILPO portal or in hard copy at the ILPO offices in Jerusalem.
• Translation of the international application. A Hebrew translation of the description and claims is required. The ILPO also accepts English-language filings in many procedural contexts, but the specification must ultimately be available in Hebrew for examination purposes. Practitioners typically file an English-language version initially and furnish the Hebrew translation within the time limit set by the ILPO.
• Certified copy of the priority document. If not already transmitted via the PCT system’s Digital Access Service (DAS), a certified copy of the priority application must be submitted.
• Power of attorney. Appointing a registered Israel patent attorney to act before the ILPO. Foreign applicants must be represented by a local attorney.
• Payment of official fees. The ILPO filing fee and any additional-claim surcharges must be paid at entry (see Section 4 below for the 2026 fee schedule).

3. How to File a Patent in Israel 2026, Step-by-Step National Phase Checklist

This chronological checklist covers the patent filing process in Israel from initial date verification through to receipt of the ILPO file number. Treat it as a project timeline and assign responsible owners for each step.

Step 0, Confirm the Earliest Priority Date and Calculate the 30-Month Deadline

Pull the priority date directly from the PCT international application (Form PCT/IB/301 or the published international application front page). Count exactly 30 months forward. If the resulting date falls on a Saturday, Friday (Shabbat), Israeli public holiday or a day the ILPO is closed due to wartime measures, the deadline extends to the next business day the office is open under PCT Rule 80.5. Calendar the deadline with at least a 60-day advance warning to allow time for translations and local counsel engagement.

Step 1, Appoint a Registered Israel Patent Attorney

Foreign applicants must appoint a patent attorney registered with the ILPO. The attorney will file on the applicant’s behalf, manage correspondence with the examiner and handle all procedural requirements. Engage counsel early, ideally at least three months before the 30-month deadline, to avoid last-minute translation bottlenecks. To explore options, visit our IP lawyer directory.

Step 2, Prepare and File the National-Phase Request Package

Assemble the complete filing package:

• Completed national-phase entry request form.
• Full specification (description, claims, abstract and drawings) in English, with Hebrew translation of the description and claims either filed simultaneously or within the ILPO’s permitted grace window.
• Signed power of attorney (original or certified copy).
• Priority document (certified copy or DAS access code).
• Assignment deed, if the applicant differs from the PCT applicant of record.

Filing may be completed through the ILPO’s online patent portal or in person at the ILPO offices. Electronic filing is strongly recommended for speed and confirmation tracking.

Step 3, Pay ILPO Official Fees

Pay the national-phase filing fee and any additional-claim surcharges at the time of entry. The ILPO accepts payment by bank transfer and, for online filings, by credit card. Retain the payment receipt, the ILPO will not assign a file number until fees are cleared. Refer to the 2026 Israel patent office fees table in Section 4 for exact amounts.

Step 4, Receive Filing Confirmation and Prepare for Examination

Once the ILPO processes the entry, the applicant receives a national application number and filing receipt. From this point the application enters the ILPO examination queue. The first substantive office action typically issues within 12 to 24 months of national-phase entry, depending on the technology field and examiner workload.

Emergency Guidance, Within 60 Days of the Deadline

If the 30-month deadline is fewer than 60 days away and no local counsel has been engaged, take these steps immediately:

• Instruct a registered Israel patent attorney on an expedited basis.
• File the national-phase request form with the minimum required documents (request form + specification + fee payment) to secure the filing date.
• Furnish remaining documents (translation, power of attorney, priority document) within the ILPO’s permitted supplementary period.
• Confirm payment clears before the deadline closes, monitor bank-transfer processing times carefully.

4. Israel Patent Office 2026 Fees, Official Costs and Example Budgets

The ILPO revised its official fee schedule effective 1 March 2026. The table below summarises the key fees relevant to PCT national-phase entry and early prosecution. All amounts are in Israeli New Shekels (ILS) as published in the ILPO’s 2026 fee schedule.

Fees as of 1 March 2026. ILS-to-USD approximate conversion: 1 ILS ≈ 0.28 USD as of April 2026. Exchange rates fluctuate, verify at time of payment.

Example Budget Scenarios

• Solo inventor (low budget). Filing fee (ILS 1,538) + examination request (ILS 1,538) + local attorney fee (estimated ILS 5,000–8,000) = approximately ILS 8,000–11,000 (≈ USD 2,250–3,100). Assumes 20 claims or fewer, English-only filing with deferred Hebrew translation.
• Pre-seed startup (medium budget). Filing + examination + Hebrew translation (estimated ILS 3,000–5,000) + local attorney fee (estimated ILS 8,000–12,000) = approximately ILS 14,000–20,000 (≈ USD 3,900–5,600). Assumes modest claim set and one round of prosecution.
• Foreign corporate filer (higher budget). Filing + examination + full Hebrew translation + grant fee + attorney fees for multiple rounds of prosecution = approximately ILS 25,000–40,000+ (≈ USD 7,000–11,200+). Complex applications in pharmaceuticals or electronics may exceed this range.

These estimates are indicative. Actual costs depend on claim complexity, translation length, the number of office actions and whether opposition proceedings arise. For cross-border budgeting strategies, see our guide on how to protect your intellectual property across borders.

5. Wartime Measures, Office Closures & ILPO Deadline Extensions

Israel’s ongoing security situation has led to intermittent ILPO office closures that directly affect the patent filing process in Israel. Applicants approaching a national-phase entry deadline or any prosecution deadline must monitor ILPO wartime notices closely.

The primary safeguard is PCT Rule 80.5: where a time limit for performing an act before the ILPO expires on a day the office is not open to the public, the time limit is automatically extended to the next day on which the office is open. This rule applies to the 30-month national-phase deadline as well as to subsequent prosecution deadlines. The ILPO PCT department publishes closure notices on its official pages, and practitioners should verify these before assuming a deadline has shifted.

In addition to Rule 80.5, the ILPO has issued special wartime notices granting blanket deadline extensions during periods of prolonged closure. The scope and duration of these extensions vary by notice, some have applied only to deadlines falling within specific date windows, while others have extended all pending deadlines by a fixed number of days. The likely practical effect is that applicants with deadlines during closure periods receive automatic relief, but the burden of confirming the applicable extension lies with the applicant and their counsel.

Restoration of Rights, How to File a Request

If the 30-month national-phase deadline has been missed, applicants may file a request for restoration of rights under the Israel Patents Law. The request must demonstrate that the failure to meet the deadline occurred despite all due care or was unintentional, depending on the applicable standard. The request is accompanied by the restoration fee (ILS 1,538 under the 2026 schedule), the full national-phase entry package and a supporting declaration explaining the circumstances of the delay. Industry observers expect the ILPO to apply a relatively strict standard; restoration is not guaranteed.

Emergency Filing Checklist During Closures

• Check the ILPO website and PCT department page daily for closure notices.
• If the online portal remains accessible during a physical closure, file electronically and retain the system-generated timestamp.
• Contact the ILPO by telephone or email to confirm receipt if no electronic confirmation is received within 24 hours.
• Instruct local counsel to monitor local news and IPAA (Israel Patent Attorneys Association) circulars for emergency extensions.
• If filing is physically impossible, document every attempt, this evidence supports a restoration request if the deadline passes.

6. Prosecution Lifecycle, Office Actions, Patent Opposition Israel & Renewals

After national-phase entry, the application enters the ILPO examination queue. Understanding the prosecution lifecycle helps applicants budget time and resources for the months and years ahead.

The first substantive office action typically issues 12 to 24 months after national-phase entry. Responses must be filed within the time limit specified in the office action, usually three to four months, with extensions available upon request and payment of additional fees. Office actions commonly address claim clarity, novelty objections (based on prior art identified during international search or supplementary Israeli search) and inventive-step arguments.

Once all objections are resolved, the ILPO issues a notice of acceptance. The applicant pays the grant fee, and the patent is published in the Patents Gazette. From the date of publication, any third party may file a patent opposition in Israel within three months. Oppositions are heard by the ILPO Registrar and may challenge the patent on any ground of invalidity, including lack of novelty, obviousness or insufficient disclosure.

Patent Term & Patent Term Extension Israel

A standard Israeli patent has a term of 20 years from the filing date (or, for PCT applications, from the international filing date). For pharmaceutical and medical-device patents, a patent term extension of up to five years may be available to compensate for regulatory delays in obtaining marketing approval. The extension must be applied for within 90 days of receiving the first marketing authorisation in Israel, and the combined patent term plus extension cannot exceed a total effective protection period set by law.

Patent renewal fees in Israel are payable annually starting from the year of grant. No renewal fees are due while the application is still pending, a significant cash-flow advantage for applicants facing lengthy prosecution.

7. Practical Tactics & Tips for Startups and Foreign Filers

Cost control and timing are the two levers that matter most when navigating how to file a patent in Israel 2026. The following tactics can materially reduce spend and risk:

• Trim claims before entry. Reducing the claim set to 20 or fewer eliminates per-claim surcharges entirely. Add dependent claims later during prosecution if needed, the ILPO is generally amenable to voluntary amendments that narrow scope.
• Use the full 30-month PCT deferral. If the commercial case for Israel is still developing, use the PCT international phase to defer national-phase costs. But calendar the deadline with an aggressive buffer, aim to file at least 30 days early.
• File in English first. The ILPO permits filing the specification in English at national-phase entry, with Hebrew translation to follow. This buys time and avoids translation bottlenecks at the deadline.
• Engage local counsel early. A registered Israel patent attorney familiar with the relevant technology can advise on claim strategy, translation quality and ILPO examiner tendencies. Early engagement prevents costly last-minute scrambles. Use our lawyer directory to identify experienced Israel IP counsel.
• Monitor ILPO wartime notices. Subscribe to ILPO announcements and IPAA circulars. A missed extension notice can mean the difference between a valid filing and a lost application.
• Budget for prosecution, not just filing. The filing fee is only the beginning. Budget for at least two rounds of office actions, a Hebrew translation of the full specification and the grant fee. Life-sciences filers should also budget for patent term extension applications.

Conclusion, Secure Your Israel Patent Filing in 2026

Knowing how to file a patent in Israel 2026 means mastering one critical deadline, 30 months from the earliest priority date, and assembling the right documents, fees and local counsel well in advance. The updated ILPO fee schedule effective 1 March 2026 and ongoing wartime deadline measures add layers of complexity that reward early preparation. Whether entering the national phase of a PCT application or filing directly, the steps outlined in this guide provide a clear, actionable roadmap.
