What Does a Patent Lawyer Do in South Africa?

A patent lawyer in South Africa is a specialist intellectual property practitioner — typically registered with the Companies and Intellectual Property Commission (CIPC) — who drafts, files, and prosecutes patent applications, advises on patentability and freedom-to-operate, represents clients in oppositions and revocations, and litigates patent infringement in the High Court under the Patents Act 57 of 1978. The role sits at the intersection of science (most patent lawyers hold a science or engineering degree in addition to their legal qualification), patent law (the Patents Act together with the Patent Cooperation Treaty, to which South Africa is a contracting state), and procedural practice before the CIPC and the courts. In day-to-day terms, a South African patent lawyer’s work is roughly evenly split between prosecution work before the CIPC and contentious work — oppositions, revocation actions, infringement litigation, and licensing and assignment disputes.

What a Patent Lawyer Is (and How the Role Differs from Other IP Roles)

A patent lawyer — often interchangeably called a “patent attorney” in South Africa — is a legal practitioner who specialises in patent law, the branch of IP law that protects inventions. The role is distinct from a trademark attorney, who handles marks, designs, and the related registers at the CIPC. A patent lawyer is also distinct from a patent agent or patent examiner, who work inside the CIPC examining applications on behalf of the registry rather than acting for applicants. In South Africa, practitioners who file and prosecute patents before the CIPC must be registered patent attorneys in terms of the Patents Act and the CIPC’s own admission rules — it is not a role any general attorney can perform without the additional registration.

The Legal Framework the Role Operates In

The Patents Act 57 of 1978 is the governing statute, read together with its regulations and the CIPC’s practice notes. The CIPC, established under the Companies and Intellectual Property Commission Act 38 of 2011, is the single national registry that replaced the former South African Patent Office and now administers patents, trademarks, designs, and copyright records. South Africa is a contracting state to the Patent Cooperation Treaty (PCT), administered by WIPO, which gives local applicants an international filing route into a national-phase application at the CIPC. South Africa is also a member of the Paris Convention for the Protection of Industrial Property, which underpins priority claims when filing in multiple jurisdictions.

Core Duty 1: Patentability Advice and Freedom-to-Operate

The first big decision a patent lawyer helps a client make is whether an invention is worth protecting at all, and if so, in what form. That work falls into four parts:

• Advising inventors and businesses on whether an invention is patentable under sections 25 and 26 of the Patents Act — novelty, inventive step, industrially applicable, and not excluded from patentability.
• Conducting and commissioning patentability searches (novelty searches) before filing to assess the chances of obtaining a granted patent.
• Conducting freedom-to-operate (FTO) analyses, which are different from patentability searches — they map existing third-party patents against a planned product or process to assess infringement risk.
• Advising on the strategic timing of filing — provisional versus complete application, and the priority date implications.

Core Duty 2: Drafting and Prosecuting Patent Applications

Once a filing decision is made, the patent lawyer’s workload moves to the CIPC side of the practice:

• Drafting patent specifications, including the description, claims, drawings (where applicable), and abstract, in the technical language the Patents Act requires.
• Filing provisional applications to establish a priority date, then complete applications (or PCT national-phase applications) within the prescribed priority year.
• Prosecuting the application through examination: responding to CIPC examiner’s reports, overcoming objections on novelty or inventive step, and arguing for allowable claim scope.
• Handling amendments to the specification and claims during prosecution, including divisional applications where the original claim set proves too broad for the CIPC to allow.
• Maintaining the patent once granted — paying renewal and annuity fees to the CIPC over the 20-year patent term from the filing date to keep it in force.

Core Duty 3: Oppositions, Revocations, and CIPC Proceedings

Not all patent work happens in chambers. The CIPC also runs a contentious side, and patent lawyers appear there regularly:

• Filing or defending oppositions to the grant of a published patent application before the CIPC under section 61 of the Patents Act.
• Filing or defending revocation actions against granted patents under section 61 — the standard grounds include lack of novelty, lack of inventive step, non-patentable subject matter, and insufficiency of disclosure.
• Appearing at hearings before CIPC adjudicators on these contentious matters.
• Advising on settlement and consent orders where revocation or opposition proceedings are resolved by amendment of the patent in suit.

Core Duty 4: Patent Infringement Litigation

Patent infringement is a court matter, not a CIPC matter. Infringement proceedings are heard in the High Court, and the patent lawyer’s work looks more like commercial litigation than anything else in the IP file:

• Issuing or defending infringement claims in the High Court, since the CIPC does not have adjudicative jurisdiction over infringement — the Patents Act vests infringement matters in the High Court under section 65.
• Preparing pleadings (particulars of claim, plea, counterclaims), managing discovery on technical document production, and instructing expert witnesses on the underlying technology.
• Arguing claim construction, infringement, and validity together — invalidity is typically raised as a defence in infringement proceedings.
• Pursuing interim relief including interdicts to stop ongoing alleged infringement, and damages or delivery-up remedies after judgment.

Core Duty 5: Commercial Patent Work

Most patent rights eventually change hands, get licensed, or sit at the centre of a deal. The commercial side of the practice is where the patent lawyer’s role intersects with the broader commercial law work that a multi-specialist firm like Burger Huyser handles across its branches:

• Drafting and reviewing patent assignment, licensing, and co-ownership agreements.
• Advising on IP clauses in broader commercial transactions (share purchase agreements, joint ventures, collaboration agreements) where patent rights form part of the deal.
• Conducting IP due diligence for mergers, acquisitions, and investment rounds.
• Advising on technology transfer arrangements and royalty structures.

What Training and Registration Is Required

The qualification pathway is one of the more demanding in the legal profession. A patent lawyer typically holds both a legal qualification (LLB or equivalent) and a science or engineering degree, since patent drafting and prosecution require reading and writing in the underlying technology. Registration as a patent attorney with the CIPC requires passing the prescribed patent attorney admission examination and meeting the CIPC’s practical and professional fitness requirements. Where the practitioner is also a litigator, they must hold an admitted-attorney or advocate practising certificate, and the relevant High Court rights of audience for infringement matters.

When You Would Actually Need a Patent Lawyer

The duties above land in a small number of recurring situations. The table below maps the most common entry points to the kind of work the patent lawyer will do:

Situation	What a Patent Lawyer Does
You have invented a product or process and want to protect it	Patentability search, drafting and filing a provisional, then a complete or PCT national-phase application, prosecution through examination
You are about to launch a product and want to know if you are infringing someone else’s patent	Freedom-to-operate analysis, opinion on infringement risk, design-around advice
A competitor has copied your product or process	Cease-and-desist correspondence, infringement summons in the High Court, interim interdict applications
You have received a CIPC examiner’s report or a notice of opposition	Response to the examiner, amendment of the application, representation at the CIPC hearing
You are buying, selling, or investing in a business with patents in its portfolio	IP due diligence, drafting or reviewing the patent assignment, advising on warranties

Working Under the Patents Act and the CIPC

Patent protection in South Africa is administered through the Companies and Intellectual Property Commission, which sits at the national registry in Pretoria and replaced the former Patent Office. Patent filings and CIPC contentious proceedings (oppositions and revocations under section 61 of the Patents Act) are handled through the CIPC’s electronic filing system and its hearings process, while infringement matters vest in the High Court under section 65 and are ordinarily heard in the division with jurisdiction over the parties or the place of alleged infringement — Gauteng, the Western Cape, and KwaZulu-Natal being the most common venues for contested patent work. South Africa is a contracting state to the Patent Cooperation Treaty, so international applicants typically enter the national phase at the CIPC within the prescribed window from the priority date.

Burger Huyser Attorneys does not run a dedicated patent prosecution practice in-house. IP matters are coordinated through the firm’s specialist IP consultant — Stefaans Gerber, Patent and Trademark Attorney — and through instructing specialist patent counsel where the technical or contentious work warrants it, with general IP queries routed through the head office in Linden, Randburg (49 First Avenue, 011 888 0246). For commercial contracts, IP clauses, shareholders’ agreements, and IP due diligence that sit alongside other commercial work, the firm’s existing commercial law practice (led by consultant J’Retha van Rensburg) already covers the adjacent ground and works in with the IP consultant as the matter requires.

Frequently Asked Questions

What is the difference between a patent lawyer and a patent attorney in South Africa?

In South African usage, “patent lawyer” and “patent attorney” are used largely interchangeably — both refer to a legal practitioner who specialises in patent law and is registered with the CIPC to file and prosecute patents. The term “patent attorney” is more strictly tied to the CIPC registration framework, while “patent lawyer” is the broader colloquial term that often also covers the litigation work in the High Court.

Do I need a patent lawyer to file a patent in South Africa?

To file and prosecute a patent application before the CIPC, you must act through a registered patent attorney — it is not a step an unrepresented applicant can take alone. For infringement litigation in the High Court, you would instruct an admitted attorney or advocate with High Court rights of audience, working with the patent attorney for the technical side.

What is the difference between a patentability search and a freedom-to-operate analysis?

A patentability search asks whether your invention is new and inventive over what already exists — it informs the chances of getting a patent granted. A freedom-to-operate analysis asks whether making, using, or selling your product or process would infringe someone else’s existing patents — it informs the risk of being sued. The two searches are complementary but distinct.

How long does a patent last in South Africa?

A South African patent has a maximum term of 20 years from the filing date, provided the prescribed renewal fees are paid to the CIPC on time. Failure to pay renewal fees results in the patent lapsing.

Can a patent lawyer also act in trademark and design matters?

Some patent attorneys also hold CIPC registration for trademarks and designs, and the broader IP practitioner role can extend across the registers. In larger firms these are often handled by separate practitioners within the same IP team.
