PCT Patent Applications for Israeli Companies: International Filing and National Phase Strategy

An Israeli company planning to protect an invention in several countries does not necessarily need to start separate patent examination procedures in every market immediately. The Patent Cooperation Treaty (PCT) offers an international application procedure that can simplify early filing, provide an international search and allow more time for decisions about overseas patent costs.

A PCT application does not grant a single international patent. It initiates an international phase followed, where the applicant chooses to proceed, by national or regional phases before the relevant patent offices. A company seeking protection in the United States, Europe, China and other markets must ultimately comply with the requirements of those jurisdictions.

How the PCT System Works for Israeli Applicants

Israel implemented the PCT in its patents legislation in the 1990s. The Israel Patent Office may act as a receiving Office for eligible applicants and also performs international search and preliminary examination functions within the treaty framework.

An eligible Israeli applicant may file an international application as an initial filing or, commonly, within 12 months after an earlier Israeli, US or other qualifying priority application. The receiving Office checks the relevant formal requirements, and the international application then proceeds through the treaty’s search and publication framework.

Foreign patent protection remains territorial. The international application is a shared procedural starting point, not a guarantee that patents will be granted in participating countries.

Filing First in Israel, the United States or Directly Under the PCT

A typical Israeli startup might first file an Israeli patent application or a US provisional application. If the company intends to preserve priority for the invention disclosed, it will normally consider a PCT application within 12 months of that first filing.

Another option is to file a PCT application as the first application, if procedural and eligibility requirements are satisfied. Choosing the receiving Office, search authority, application language and initial filing strategy should account for technical readiness, planned patent markets, costs and special rules relevant to inventions developed in Israel.

The benefit of the earlier filing date does not extend automatically to new technical matter added in a later PCT application. Claims relying on material not supported by the initial disclosure may receive a later effective date.

The International Search Report and Written Opinion

After filing, the International Searching Authority (ISA) conducts a search and prepares an International Search Report (ISR). It also provides a Written Opinion addressing, among other matters, novelty, inventive step and industrial applicability. This analysis is useful for evaluating the prospects of a foreign filing program and for deciding which claim amendments or additional development might be needed.

The international opinion is not binding on national patent offices. Even a favorable report does not ensure grant in the US, Europe, China or Israel. Conversely, an unfavorable opinion may be answered or addressed through permissible amendments and arguments as the application proceeds.

International publication normally takes place around 18 months from the earliest priority date. The applicant can use the international phase to discuss licensing, potential investors, commercial validation and patent budgets while preparing a national-phase strategy.

Optional International Preliminary Examination

The applicant may request international preliminary examination under Chapter II of the PCT, subject to treaty conditions and applicable fees. This procedure allows further interaction with an International Preliminary Examining Authority (IPEA) and may assist in assessing amended claims or responding to concerns in the initial opinion.

The procedure does not substitute for national examination, and the resulting report does not compel a national authority to grant a patent. Its value depends on the claim set, identified prior art, expected national filings and budget.

National Phase Entry: 30 Months Is Not Universal

For many PCT contracting states, the normal national-phase deadline is 30 months from the earliest priority date. Some offices provide longer periods. The European Patent Office generally allows 31 months for entry into the European phase. China generally requires national-phase entry within 30 months, subject to specific procedures and potential late-entry relief under local rules.

Dates must be calculated for each selected jurisdiction, taking account of the actual priority claim and local procedural requirements. The company must not assume that a deadline applicable in Europe also applies in China or the United States.

At national or regional phase entry, the applicant may need to appoint local counsel, file a translation, submit prescribed documents and pay official fees. Patent prosecution then proceeds under the relevant national or regional patent law. See WIPO’s PCT Applicant FAQ for the official international system overview and WIPO’s PCT Applicant’s Guide for procedural detail.

Example: An Israeli Company Planning Global Protection

Suppose an Israeli company files its first patent application for a new industrial sensor in January 2027. It may consider filing a PCT application no later than the applicable 12-month priority deadline in January 2028. It can then assess whether to enter selected national and regional phases roughly 30 to 31 months from the first application, depending on the destination.

During that period, the company can evaluate pilot customers in Germany, US distribution prospects and manufacturing arrangements in China before committing to local prosecution costs. The PCT route gives more time for commercial decisions; it does not remove the need to make them or create patent rights automatically in those territories.

How Much Does an International PCT Filing Cost?

The international stage may include a transmittal fee, international filing fee, search fee, and professional fees for drafting and filing, with additional costs if preliminary examination or other special procedures are requested. Fee reductions and exact rates depend on the applicant and receiving or search authorities under the current rules.

The larger and often more consequential expense arises when entering multiple national or regional phases. Each destination may require patent counsel, translations, official filing fees and subsequent examination and maintenance payments. Choosing a PCT filing is therefore usually a budgeting and timing strategy rather than a way to eliminate foreign filing expenses.

Choosing Overseas Markets and Managing the Patent Portfolio

Israeli applicants should prioritize jurisdictions according to manufacturing sites, expected sales, licensing partners, competitors and enforcement conditions. Filing everywhere is rarely economically sensible. Patent rights in one market do not automatically provide a remedy for conduct occurring exclusively in another.

The PCT strategy should be coordinated with the company’s other intellectual property, confidentiality arrangements and investor disclosure timetable.
