Quick Answer: Under Section 132 of the Patents Law 5727-1967, a "service invention" — one that arises from an employee's work and relates to the employer's business — belongs to the employer by default, even without a written assignment. The employer's right extends for one year after termination under Section 133. Software and other creative works follow a parallel rule under Section 34 of the Copyright Law 5768-2007. Critically, independent contractors own their IP unless the contract expressly assigns it — a common and expensive omission for foreign tech companies hiring Israeli developers.

Every foreign company that hires engineers, developers, or researchers in Israel is navigating a legal framework that determines who owns whatever those people create. The answer is not always obvious: Israeli law says different things about employees versus contractors, about work-time inventions versus after-hours creations, and about the period immediately after someone leaves the company. Getting this wrong costs real money. A senior developer who leaves your Tel Aviv R&D centre and files a patent application within twelve months for a product line they were building for you has a viable claim to that IP if your contracts did not address the issue correctly.

This guide walks through the Israeli statutory framework, explains where the law protects employers by default and where it does not, and sets out what employment and contractor agreements need to say to close the gaps.

1. Service Inventions Under Section 132 of the Patents Law

The foundation of Israeli employee IP law is the concept of the המצאת שירות (hamtza'at sherut) — the "service invention." Section 132(a) of the Patents Law 5727-1967 defines a service invention as one that was made by an employee in the course of, or as a result of, their employment — or that uses the employer's materials, resources, information, or knowledge.

The default rule is straightforward: a service invention belongs to the employer. The employee has no claim to the patent, the right to use it, or any proceeds from licensing it, unless the employer specifically grants these rights back. The employer does not need a written assignment clause for this to apply — the statutory default is automatic.

The scope is deliberately broad. An invention qualifies as a service invention if it relates to the employer's actual field of activity, if it was made using the employer's time, equipment, or confidential information, or if the employee was hired specifically to invent or solve problems of the type from which the invention arose. Any one of these three triggers is sufficient on its own.

In Practice — What "Related to the Employer's Business" Actually Means

The Israeli National Labor Court has interpreted the "related to the employer's field" test broadly. In a 2019 decision involving a developer at a cybersecurity company, the court held that an encryption algorithm the employee developed for a side project fell within the employer's field because the employer's products involved encryption, even though the specific application was different. The practical standard: if a reasonable competitor in your industry would want the invention, it is probably within your field. Foreign tech companies should therefore include a contract clause explicitly extending the employer's claim to any invention connected to the company's field — not because Section 132 requires it, but because a written clause is far easier to enforce than a disputed statutory interpretation. The Israel Patent Authority (Rashut HaPatentim) processes patent assignments from employer to employee or vice versa, but the underlying ownership question is determined by the Labor Court, not the Patent Office.

Software, written documentation, database structures, designs, and any other original works fall under the Copyright Law 5768-2007 rather than the Patents Law. Section 34 of the Copyright Law sets the default rule for employed creators: where a work of copyright is created by an employee in the course of their employment, the copyright belongs to the employer unless the parties have agreed otherwise.

The phrase "in the course of employment" covers more than work performed physically at the office. A developer who writes code at home on a personal laptop, for a project that is part of their job scope, has created the work in the course of their employment. The test focuses on the employment relationship and the assignment of work, not the location or equipment used.

The employer's copyright ownership under Section 34 covers the full range of rights: reproduction, distribution, public display, creation of derivative works, and licensing. The employee retains the moral right to attribution under Section 46 of the Copyright Law, but moral rights do not affect economic ownership and cannot be invoked to block the employer from using, modifying, or licensing the work.

For software companies specifically, this default employer-owns rule is the foundation on which every product is built. But it only applies to employees. Contract developers — even those who work exclusively for one company on a long-term basis — are not employees under Israeli law, and the Section 34 default does not protect the client company. This distinction is the most common IP vulnerability in Israeli tech hiring.

3. When the Employee Keeps Their IP

The employer-owns default is not universal. Section 132(b) of the Patents Law carves out a category of inventions that belong to the employee regardless of what their contract says:

  • The invention has no connection to the employer's field of activity; and
  • The invention was not made using the employer's resources, materials, information, or time.

Both conditions must be met together. An invention made on personal time but in a field closely related to the employer's work remains a service invention. An invention that used even a small amount of employer resources — including employer-paid conference information or a company laptop — falls within the employer's default claim even if it is in an entirely unrelated field.

The typical case where an employee genuinely retains IP: a software developer at a logistics company who, in their personal time and using personal equipment, writes a mobile game unrelated to logistics. Provided the developer's role at the company does not involve gaming or the technologies the game uses, the employer has no claim. The moment there is any connection to the employer's business or any use of employer resources, the analysis shifts.

4. The One-Year Post-Termination Window

One of the most commercially significant provisions of Israeli IP law is the post-termination extension in Section 133 of the Patents Law. This section provides that the employer's rights extend to inventions the former employee makes within one year of termination, if the invention derives from the work they did during employment or from information they obtained in the course of that employment.

The one-year window is automatic. It does not depend on a contractual provision, and it cannot be shortened by the employee's unilateral decision to "work on something new" immediately after leaving. An engineer who spent three years developing a machine-learning model for a company, resigns, and files a patent application five months later for an improved version of the same model, faces a direct Section 133 claim by the former employer.

The employer's burden of proof is to show the connection between the post-termination invention and the work or information from employment. The employee's burden is to show the invention is genuinely independent. Courts in Israel examine the technical similarity, the timing of conception, the employee's notebooks and communications, and the extent to which the invention builds on prior work done at the company.

In Practice — The Post-Termination Disclosure Obligation and Its Limits

Section 133 gives the employer the right; it does not automatically create an obligation for the former employee to report what they are working on. Employment contracts should include an express disclosure obligation requiring the departing employee to notify the company of any patent applications or registrations filed within the post-termination period that touch the company's field. Without this clause, an employer who learns 13 months after termination about a closely related patent application that was filed 11 months after termination has to act quickly. The National Labor Court has a 7-year limitation period for IP claims generally, but the practical window for injunctive relief is far shorter — once a third party has licensed or purchased the invention, the remedy shifts from ownership recovery to damages. Foreign companies that run distributed R&D teams across multiple jurisdictions should note that Section 133 applies to work done in Israel regardless of where the employee moves after termination; Israeli courts have asserted jurisdiction over Section 133 disputes where the development work was performed in Israel.

5. Contractors and Freelancers: A Separate and Critical Rule

The employer-default rules in Section 132 of the Patents Law and Section 34 of the Copyright Law apply only to employees. A person working as an independent contractor — even under a full-time, long-term service agreement — is not covered by either default. The IP created by a contractor belongs to the contractor unless the contract transfers it to the client.

This is the most common and costly IP mistake made by foreign companies operating Israeli R&D centres. The typical scenario: a foreign company hires a Tel Aviv developer under a services agreement, treating them as an independent contractor (*nose be-azmao*) for employment classification purposes. The developer writes tens of thousands of lines of code. When the company tries to patent a product based on that code or license it to a buyer, it discovers it does not own the copyright because the developer's contract never included an IP assignment clause.

To transfer IP from a contractor to a client under Israeli law, the contract must include:

  • An express assignment of all intellectual property rights, including copyright, patent rights, moral rights waiver, and any related rights;
  • Language that the assignment covers works made in connection with the engagement, past and future;
  • A representation that the contractor has the right to make the assignment (i.e., the work is original and not encumbered by third-party rights);
  • A cooperation clause obligating the contractor to sign additional documents if needed for patent or copyright registration.

A general "work-for-hire" provision is not sufficient under Israeli law because Israeli copyright law does not recognize a work-for-hire concept analogous to US law. The assignment must be explicit. Courts have consistently declined to imply an IP transfer from the contractor's obligation to perform services.

In Practice — Reclassification Risk Creates a Double IP Exposure

Foreign companies that classify Israeli workers as independent contractors and omit IP assignment clauses face two simultaneous risks. The first is the IP ownership gap described above: no assignment clause means the contractor may own the work. The second is reclassification: if the National Insurance Institute (NII / Bituach Leumi) or the National Labor Court later determines the contractor was actually an employee — based on the degree of integration, exclusivity, tools provided, and control exercised — the company suddenly owes back social insurance contributions, severance pay under the Severance Pay Law 5723-1963 at one month per year of service, and retroactive vacation pay. In the reclassification scenario the IP question resolves in the company's favor (Section 132 of the Patents Law applies to employees), but the financial exposure from the employment reclassification typically far exceeds the value of most IP. Use a properly structured contractor agreement that includes both a clear IP assignment and appropriately arms-length commercial terms. The NII conducts routine audits of technology companies with large contractor populations and has issued assessments exceeding NIS 2 million to mid-sized companies for unpaid contributions on misclassified contractors.

6. The Employee's Right to Adequate Remuneration

The fact that an invention belongs to the employer does not necessarily mean the employee receives nothing beyond their salary. Section 134 of the Patents Law 5727-1967 gives an employee the right to claim "adequate remuneration" (*tgomul hagun*) from the employer where a service invention they created has made an exceptional contribution to the employer's business.

This right is non-waivable: a contract clause that purports to exclude the employee's Section 134 claim in advance is void. Employees must bring Section 134 claims in the National Labor Court, and the court has broad discretion in determining what constitutes "adequate."

The practical bar is high. Israeli courts award Section 134 remuneration only where the invention's contribution is documented to be extraordinary relative to the employee's role and compensation. A developer who was hired specifically to build a product, received standard market-rate compensation, and now seeks a share of the product's revenue typically does not meet the threshold. A researcher who was hired for a different purpose but happened to invent something that became the company's core patent — generating hundreds of millions of shekels in licensing revenue while receiving a junior researcher's salary — has a stronger argument.

For foreign companies managing Israeli R&D teams, the practical implication is that unusually valuable patents with a single named inventor who earned a modest salary represent a litigation risk. Structuring compensation packages that include some direct participation in the commercial success of key inventions — through bonuses, equity, or royalty rights — reduces this exposure significantly and is better practice than relying on the employer's statutory default plus a blanket contract clause.

7. What Employment and Contractor Agreements Must Include

Israeli employment contracts in technology and research sectors should address IP in a dedicated section that goes beyond what the Patents Law requires. The statutory default protects employers in the core case — a standard employee invents something related to their job — but it leaves gaps in several important scenarios.

For employees, include:

  • An express IP assignment clause confirming the statutory employer ownership and extending it contractually to works that may fall in grey areas between Section 132's coverage and purely personal inventions;
  • A disclosure obligation requiring the employee to report all inventions and creative works created during employment or within one year of termination that relate to the company's field;
  • A confidentiality obligation under the Commercial Torts Law 5759-1999 covering trade secrets, both during employment and for a reasonable post-employment period (Israeli courts accept 12 to 24 months as reasonable; longer periods are scrutinized);
  • A cooperation clause requiring the employee to sign patent applications, assignment documents, and other filings for works created during employment, even after leaving;
  • A moral rights waiver covering the employee's right to attribution under Section 46 of the Copyright Law, to the extent the company needs to publish or license the work without crediting the author.

For independent contractors, the requirements are stricter because there is no statutory default to rely on:

  • An express, irrevocable assignment of all IP rights in works created in connection with the engagement — covering inventions, software, documentation, designs, and any derivative works;
  • A representation that the contractor has full authority to make the assignment and that the work does not infringe third-party IP;
  • A moral rights waiver (which must be explicit under Israeli law to be effective);
  • A cooperation clause obligating the contractor to sign additional documents needed for registration or enforcement;
  • A confirmation that the assignment applies to works from the start of the engagement, not only from the date of the agreement, to cover any prior work already performed.

8. Israel Innovation Authority Grant Recipients: Additional Restrictions

Foreign companies that own Israeli R&D operations funded by the Israel Innovation Authority (IIA) face an additional constraint that operates independently of the employer-employee IP rules discussed above. Under Section 19 of the Research and Development Law (*Chok Omdan*) 5744-1984, a company that received IIA grants may not transfer IP developed using those grants outside Israel — and may not exclusively license the IP to a foreign entity — without prior IIA approval.

This restriction applies even when the IP unambiguously belongs to the employer under Section 132 of the Patents Law. A technology company with full contractual and statutory ownership of its Israeli employees' inventions can still be blocked from transferring those inventions to its foreign parent without IIA consent. The penalty for unauthorized transfer is repayment of the grant plus interest, and in serious cases, loss of eligibility for future IIA support.

Approval for IP transfer outside Israel requires filing a detailed application with the IIA, paying a royalty on future revenues from the transferred IP (typically 3% to 5% of sales derived from the technology), and meeting "Israeli nexus" requirements that vary depending on the stage of the grant. For foreign companies acquiring Israeli tech companies that have received IIA funding, this is a standard due diligence item — the acquisition cannot complete without IIA consent on the IP transfer if the target holds funded IP.

Frequently Asked Questions

It depends on the connection to the employer's business. Under Section 132(b) of the Patents Law 5727-1967, an invention with no connection to the employer's field, developed without using employer resources, belongs to the employee even if made on personal time. However, if the invention is related to the company's field of activity — even loosely — the employer's Section 132(a) default applies. The test focuses on the connection to the employer's business, not the time or location of creation. Employment contracts in Israeli tech companies routinely extend the employer's claim to any IP connected to the company's field, which strengthens the position beyond the statutory default.
Yes. Under Section 134 of the Patents Law 5727-1967, an employee whose service invention made an exceptional contribution to the employer's business can petition the National Labor Court for "adequate remuneration" (tgomul hagun). This right cannot be waived by contract in advance. The Labor Court awards such remuneration rarely, and only where the contribution is documented to be extraordinary. Courts weigh the commercial value of the invention, the employee's role, their compensation at the time, and the degree to which employer resources were used. The Israel Innovation Authority notes that this provision creates particular risk for technology companies that patent employee-developed inventions worth significantly more than the employee's total compensation during development.
Section 133 of the Patents Law 5727-1967 extends the employer's rights to inventions made within one year of termination, where the invention derives from the employee's work during employment or from information they obtained there. This one-year post-termination window is automatic and requires no contractual provision. An employee who leaves a tech company and files a patent within 12 months for something related to their former employer's product line faces a strong legal claim by the former employer. Employment agreements should include a disclosure obligation for any invention filed within the post-termination period, even though the statute does not expressly require it.
The employer-default rule in Section 132 of the Patents Law applies to employees only, not independent contractors. A freelancer or contractor who creates software, designs, or an invention for a client owns the intellectual property unless the contract expressly assigns it to the client. The Copyright Law 5768-2007 mirrors this in Section 34: copyright in employee-created works belongs to the employer, but a contractor's work belongs to the contractor without a written assignment. Foreign companies that hire Israeli contractors without an IP assignment clause in the service agreement have no legal ownership of the work product. This is one of the most common and expensive IP mistakes foreign tech companies make when engaging Israeli developers through service agreements.
At minimum, every Israeli employment contract should include: an express IP assignment clause covering inventions, software, designs, and trade secrets created during employment and related to the company's business; a confidentiality obligation under the Commercial Torts Law 5759-1999 covering trade secrets during and after employment; a disclosure obligation requiring employees to report inventions made during or within one year after employment; and a post-employment cooperation clause for patent filings. Companies that received Israel Innovation Authority grants face an additional constraint — transferring or exclusively licensing IP outside Israel requires prior IIA approval, regardless of what the employment contract says.
