Sample PEB Practical Patent Problems Practice Questions

Try these sample questions to test your PEB Practical Patent Problems exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under South African patent law, how should patent claims be interpreted according to the locus classicus Gentiruco AG v Marks & Spencer Ltd?

A.Claims must be interpreted in light of the specification, but words must be given their plain, ordinary meaning unless the specification defines them differently.

B.Claims should be interpreted exclusively by reference to extrinsic evidence and expert witness testimony regarding technical intent.

C.Claims must always be construed broadly to give the patentee the widest possible monopoly regardless of clear limiting language.

D.Claims are interpreted by referring to the prosecution history file wrapper maintained at the Patent Office.

Explanation: In Gentiruco AG v Marks & Spencer Ltd 1974 (4) SA 563 (A), the Appellate Division established that a patent claim must be construed in the context of the specification as a whole. Words are given their plain, natural, and ordinary meaning unless the specification explicitly acts as its own dictionary. Extrinsic evidence such as prosecution history is generally inadmissible to alter clear claim language.

2In applying the doctrine of purposive construction (Catnic / Aktiebolaget Hässle v Mylan) under South African law, when will a minor variant escape infringement?

A.When the variant falls outside an integer that a person skilled in the art would understand was intended by the patentee to be an essential integer.

B.Whenever the alleged infringer proves that their commercial embodiment is superior to the patented invention.

C.Whenever the variant achieves a slightly different color or aesthetic appearance regardless of technical function.

D.Only when the variant was patented by the defendant prior to the plaintiff's priority date.

Explanation: Under the purposive construction approach approved in Aktiebolaget Hässle v Mylan (Pty) Ltd 2015 (4) SA 415 (SCA) and Catnic, if a skilled person would understand that strict compliance with a particular claim word/integer was intended to be an essential requirement of the invention, any variant outside that essential integer avoids infringement. If the integer is non-essential, a variant that operates in substantially the same way to achieve the same result will still infringe.

3Which of the following acts constitutes direct patent infringement under Section 45(1) of the Patents Act 57 of 1978 in respect of a product patent?

A.Making, using, exercising, offering for sale, disposing of, or importing the patented product in South Africa without authorization.

B.Publishing a academic critique evaluating the scientific principles behind the patented product.

C.Filing a patent application in a foreign jurisdiction for a related invention.

D.Purchasing an authorized patented product from the patentee's exclusive licensee in South Africa.

Explanation: Section 45(1) of the Patents Act 57 of 1978 grants the patentee the exclusive right to make, use, exercise, offer for sale, dispose of, or import the patented invention in the Republic. Unauthorized performance of any of these acts within South Africa during the patent term constitutes direct infringement.

4What is the legal position regarding indirect or contributory infringement under South African patent law?

A.There is no statutory provision for contributory infringement, but liability can arise under common law delict for aiding or procuring direct infringement.

B.Contributory infringement is automatically strict liability under Section 45(3) whenever unpatented spare parts are sold.

C.Selling standard off-the-shelf staples of commerce is per se criminal patent infringement under Section 70.

D.Indirect infringement is governed exclusively by the Competition Act 89 of 1998 rather than the Patents Act or common law.

Explanation: The South African Patents Act 57 of 1978 does not contain a specific statutory provision creating liability for contributory or indirect infringement. However, under South African common law of delict, a party who intentionally aids, abets, procures, or induces another to commit direct patent infringement can be held jointly liable as a joint wrongdoer.

5Under Section 69A of the Patents Act 57 of 1978 (the 'Bolar' provision), which action is protected from being an infringement?

A.Making, using, or testing a patented invention solely for obtaining regulatory approval for a pharmaceutical product.

B.Stockpiling patented medicines for commercial sale three years prior to patent expiry.

C.Selling patented medical devices to commercial private hospitals for profit during the patent term.

D.Exporting patented active ingredients to foreign markets for immediate commercial distribution.

Explanation: Section 69A provides a statutory exception permitting acts performed solely on a non-commercial scale for development and submission of information required under South African or foreign law regulating the manufacture or sale of products (such as health regulatory submissions to SAHPRA). Commercial stockpiling, sales, or commercial exports are not protected by Section 69A.

6A South African company purchases patented mining equipment in Germany directly from the global patent owner and imports it into South Africa. Does this importation constitute infringement?

A.No, because authorized sale by the patentee anywhere in the world exhausts the patent owner's rights unless express territorial restrictions were attached at sale.

B.Yes, because South African patents strictly enforce regional national exhaustion with no exceptions.

C.Yes, because importing any patented item requires a statutory license from the CIPC Registrar.

D.No, but only if the importer pays a compulsory 15% tariff to the South African Revenue Service.

Explanation: Under South African patent law principles, an unrestricted sale of a patented article by the patentee (or licensee acting within scope) anywhere in the world carries an implied license to use, import, and dispose of that article, exhausting patent rights unless clear express restrictions were imposed and communicated at the time of sale.

7What is the relationship between the 'pith and marrow' doctrine and modern purposive construction in South Africa?

A.Purposive construction subsumes the pith and marrow principle by determining whether integers are essential or non-essential based on the patentee's practical purpose.

B.Pith and marrow has been formally abolished by statute in the 1978 Patents Act and replaced by strict literalism.

C.Pith and marrow applies exclusively to chemical patents, while purposive construction applies to mechanical patents.

D.Purposive construction allows courts to re-write claims to include unstated features.

Explanation: As clarified in Aktiebolaget Hässle v Mylan, modern purposive construction builds upon the traditional 'pith and marrow' doctrine. Instead of applying rigid literalism or unrestricted equivalence, purposive construction asks whether a person skilled in the art would understand from the claim language and specification that strict compliance with an integer was an essential requirement of the invention.

8What is the territorial scope of protection granted by a South African patent issued under Act 57 of 1978?

A.It extends throughout the Republic of South Africa, including its territorial waters and airspace, but not to foreign countries.

B.It automatically grants protection across all SADC (Southern African Development Community) member states.

C.It protects acts performed anywhere in Africa provided the patent owner is registered in Pretoria.

D.It covers global manufacturing provided the final product is marketed in Johannesburg.

Explanation: A South African patent is strictly territorial. Under Section 45(1), the rights granted apply only within the boundaries of the Republic of South Africa (including territorial waters). Separate patent applications or regional/international filings (e.g. PCT or ARIPO/OAPI where applicable) are required to secure rights in other jurisdictions.

9A manufacturer in Durban manufactures all individual component parts of a patented combination lock in South Africa, but exports them in unassembled kit form to Namibia for final assembly. Does the manufacturing in Durban infringe a South African combination claim?

A.Yes, if manufacturing the components in South Africa amounts to making the essential parts of the patented combination, or if the product claim covers the combination assembly as made.

B.No, because patent infringement can only occur if the final assembly takes place inside South Africa.

C.No, because exporting goods out of South Africa is totally exempt from patent law under international trade treaties.

D.Yes, but only if the Namibian assembler pays royalties to the South African Patent Office.

Explanation: Manufacturing all components of a patented combination within South Africa constitutes 'making' or exercising the invention or taking essential steps in making the patented product in South Africa under s45(1), even if assembly is completed across the border. Making the parts in SA to fulfill the combination claim constitutes direct infringing manufacture.

10If a patent claim specifies a support frame inclined at 'vertical, that is 90 degrees', and an alleged infringing frame is inclined at 86 degrees, what inquiry must the Commissioner of Patents undertake?

A.Determine whether '90 degrees' was intended as an essential integer requiring strict adherence, or whether a 4-degree variance falls within a non-essential range under purposive construction.

B.Automatically rule that 86 degrees cannot infringe because 86 is numerically unequal to 90.

C.Invalidate the patent immediately for claiming impossible mathematical precision.

D.Order the defendant to adjust their frame to 90 degrees before hearing arguments.

Explanation: Following the classic Catnic reasoning (Catnic Components v Hill & Smith), the court must decide whether a person skilled in the art would understand that strict verticality (exactly 90 degrees) was an essential requirement of the invention, or whether minor practical variations (86 degrees) perform the exact same function in the same way without affecting performance.
