What is an employee confidentiality and IP assignment?
Does an employer own its employees’ IP in South Africa?
“Where in a case not falling within either paragraph (b) or (c) a work is made in the course of the author’s employment by another person under a contract of service or apprenticeship, that other person shall be the owner of any copyright subsisting in the work by virtue of section 3 or 4.”
“The computer programs were written in the course of King’s employment under a contract of service, so the South African Weather Service — not the employee — owned the copyright. Whether work is made “in the course of” employment is a broad, factual enquiry into how the work relates to the employer’s business and the employee’s duties, not a narrow test of what the contract strictly required.”
“An employer may claim an employee’s invention made in the course and scope of the employee’s duties, but section 59(2) renders void any contractual term purporting to assign inventions made outside those duties, or to bind the employee for more than one year after the employment ends.”
When you need a Employee Confidentiality & IP Assignment
- When hiring developers, designers, engineers, writers, marketers or any staff who will create software, content, drawings, designs or inventions you need to own — especially where the work could be argued to fall outside their core job description.
- When commissioning photographs, videos, sound recordings or portraits, where section 21(1)(c) of the Copyright Act can hand ownership to the commissioner but written terms still avoid disputes — and where independent contractors (who are not employees) own their work unless it is assigned.
- When an employee may invent something patentable or create a registrable design, so the business can secure those rights up front while staying inside the section 59(2) limits on what can be claimed.
- When staff handle trade secrets, source code, client and pricing data, formulations or unpublished plans, and you need an enforceable confidentiality duty that survives the end of the employment relationship.
- When preparing a business for sale, investment or due diligence, where a buyer or investor will require a clean, written chain of title to all the IP the company depends on.
What a Employee Confidentiality & IP Assignment should contain
Present and future assignment of IP
An express assignment to the employer of all intellectual property the employee creates in connection with the business — copyright, inventions, designs and know-how — worded to cover both existing and future works. This closes the gap the Copyright Act leaves for commissioned works and any work that might be argued to fall outside “the course of employment” under section 21(1)(d).
Definition of confidential information and trade secrets
A precise definition of what the employee must keep secret — source code, customer and pricing data, formulations, business plans, and information marked or reasonably understood to be confidential — with the duty continuing after the employee leaves. Tight definitions anchor the secrecy obligation to genuinely protectable information rather than everything the employee ever saw.
Scope: “in the course of employment” and beyond
Language confirming that IP made using the employer’s time, resources, information or facilities belongs to the employer, mirroring the broad King v SA Weather Service test. This avoids the employee later arguing that a particular work — written after hours or outside their formal duties — was their own private project.
Patents and designs — within the statutory limits
A clause securing inventions and registrable designs made in the course and scope of the employee’s duties, drafted to respect section 59(2) of the Patents Act: it must not purport to claim inventions made outside those duties, nor bind the employee for more than one year after termination, or that part of the clause is void.
Waiver of moral rights and further assurance
Because section 20 of the Copyright Act preserves the author’s moral rights (paternity and integrity) even after copyright is assigned, the clause should address moral rights to the extent permitted and include a “further assurance” undertaking — the employee agrees to sign any document and do anything reasonably needed to perfect and register the employer’s ownership.
Third-party and open-source IP
A warranty that the employee will not embed third-party or open-source material that compromises the employer’s ownership or imposes unwanted licence conditions, and will disclose any pre-existing IP they bring in. This protects the clean chain of title a buyer or investor will demand on due diligence.
Return of materials and POPIA-aligned handling
An obligation to return or destroy confidential material, code and copies (including electronic copies) when employment ends, and to handle any personal information in line with the Protection of Personal Information Act 4 of 2013. Where the confidential information includes personal data, the employee’s secrecy duty should track the employer’s own POPIA obligations.
Remedies, interdict and survival
A statement that a breach of confidentiality or the IP undertakings causes harm not adequately met by damages, that the employer may seek an interdict, and that the confidentiality and assignment obligations survive termination. Confidentiality and IP breaches are typically restrained by urgent interdict in the High Court.
Confidentiality & IP assignment vs restraint of trade vs NDA
| Feature | Confidentiality & IP assignment | Restraint of trade | NDA / confidentiality |
|---|---|---|---|
| Main job | Secures ownership of IP the employee creates, plus secrecy | Stops the person competing, working for a rival or soliciting | Stops disclosure or misuse of defined confidential information |
| Who it binds | Employees (and is adapted for contractors via assignment) | Employees, sellers of a business, partners | Any party receiving confidential information |
| Key SA authority | Copyright Act s 21(1)(d); King v SA Weather Service; Patents Act s 59 | Magna Alloys v Ellis; Reddy v Siemens (reasonableness) | Common law of contract + confidential-information law |
| Time limit | Secrecy can be indefinite; patent claims capped at 1 year post-employment (s 59(2)) | Must be a reasonable, defined period | A set period, or while the information stays secret |
| Default without it | Employer owns most copyright by law, but gaps remain | No restraint applies unless agreed | Confidential info still protected, but harder to prove |
Common South African pitfalls
- Assuming the Copyright Act covers everything: section 21(1)(d) only gives the employer copyright in work made in the course of employment under a contract of service. It does not automatically cover commissioned works (s 21(1)(c)), work by independent contractors, or other IP — so relying on the default alone leaves ownership gaps a written assignment would close.
- Over-reaching on patents and designs: section 59(2) of the Patents Act makes void any term that tries to claim inventions made outside the employee’s normal duties, or to bind them for more than one year after employment ends. A greedy assignment clause does not just fail — the offending part is struck out, which can poison the whole provision if it is not carefully drafted.
- Treating contractors like employees: the “course of employment” default applies to employees under a contract of service, not to independent contractors. A freelancer or agency keeps the copyright in what they create unless there is an express assignment, so using an employee clause for a contractor leaves the business without ownership.
- Ignoring moral rights: section 20 of the Copyright Act preserves the author’s moral rights even after the economic copyright is assigned. A clause that assumes assignment wipes out all the author’s rights can mislead the employer about what it actually holds — moral rights must be addressed separately.
- No “further assurance” or registration cooperation: ownership by operation of law is not the same as a registered, perfected title. Without an obligation on the employee to sign assignments and assist with registration, the employer can struggle to record or enforce its rights once the employee has left — exactly when a dispute or a sale arises.
Frequently asked questions
Does an employer own copyright in work created by an employee in South Africa?
Yes, by default. Section 21(1)(d) of the Copyright Act 98 of 1978 gives the employer copyright in any work made by an employee in the course of employment under a contract of service. The Supreme Court of Appeal confirmed this in King v South African Weather Service, where the employer owned the software an employee wrote on the job.
If the law already gives the employer copyright, why sign an IP assignment?
Because the statutory default has gaps. It only covers copyright in work made “in the course of employment” under a contract of service — not commissioned works, work by independent contractors, patents, designs, or copyright the employer needs to assign on rather than own automatically. A written assignment closes those gaps and lets the employer register and enforce a clean title.
What did King v South African Weather Service decide?
The Supreme Court of Appeal held that computer programs written by an employee belonged to his employer because they were made in the course of his employment. The court took a broad, factual approach — looking at how the work related to the employer’s business and the employee’s duties — and held the work need only be made in the course of employment, not strictly required by the contract.
Can my employment contract claim every invention an employee makes?
No. Section 59(2) of the Patents Act 57 of 1978 lets an employer claim inventions made in the course and scope of the employee’s duties, but makes void any term that tries to take inventions made outside those duties, or to bind the employee for more than one year after employment ends. An over-reaching clause is cut down, so it must be drafted within those limits.
Do I need an IP assignment for independent contractors and freelancers?
Yes — it is essential. The “course of employment” default applies to employees, not contractors. A freelancer, agency or consultant keeps the copyright in what they create unless they expressly assign it to you in writing. Without that assignment, you may have paid for work you do not actually own.
How long does a confidentiality obligation last after employment ends?
A well-drafted confidentiality duty can continue indefinitely for genuine trade secrets and confidential information, and survives the end of the employment relationship. That is different from a restraint of trade (which must be for a reasonable period) and from the one-year cap that section 59(2) places on claiming an employee’s post-employment inventions.
What is the difference between this and a restraint of trade?
A confidentiality and IP assignment secures ownership of what the employee creates and keeps the employer’s secrets safe. A restraint of trade stops the person competing, joining a rival, or soliciting clients and staff after they leave. They do different jobs and are tested differently — restraints must be reasonable, while IP ownership turns on the Copyright and Patents Acts.
Does POPIA affect employee confidentiality clauses?
It can. Where the confidential information the employee handles includes personal information, the Protection of Personal Information Act 4 of 2013 imposes its own duties of security, purpose-limitation and proper disposal. A good confidentiality clause should track those duties — for example requiring return or destruction of data on exit — rather than contradict them.
