SAFEGUARDING INNOVATION IN KENYA: A CASE STUDYOF A SOLAR-POWERED WATER PURIFICATION INVENTION

Abstract

This article draws on a scenario in which my friend Mary, a young entrepreneur in Nairobi, approached me regarding innovation protection in Kenya. Mary informed me that she had recently invented a device to purify water using solar energy. She was unsure whether her invention qualified as intellectual property and sought legal advice on how to protect it.

In light of this scenario, this article explains the scope and nature of intellectual property rights under Kenyan law, defines what qualifies as intellectual property under Kenyan law, and outlines the main types of intellectual property legally recognised in Kenya.

Having clarified the different types of intellectual property, the article proceeds to determine the type of intellectual property best suited to Mary’s situation and provides a structured legal analysis of the process of securing a patent in Kenya, including the procedural steps involved in the grant of a patent by the Kenya Industrial Property Institute (KIPI).

This article aims to enlighten innovators who find themselves in a position similar to Mary’s, thereby contributing to greater legal awareness on intellectual property in Kenya.

Nature of Intellectual Property Rights

Intellectual property encompasses various products of human creation, including literary works, symbols, designs, inventions, and trade secrets. These products are safeguarded through copyrights, patents, trademarks, and trade secret laws, which in turn promote innovation and support economic development. What unites all of the different rights that fall under the umbrella term “intellectual property” is that the subject matter of protection is intangible.¹

In 2012, the Supreme Court of the United Kingdom, in an attempt to define the scope of intellectual property, observed the following:

There is a general consensus as to its core content (patents for inventions, literary, dramatic, musical and artistic copyrights, copyright in recordings, films and broadcasts, registered and unregistered design rights and trademarks…) but no general consensus as to its limits.”²

Types of Intellectual Property Rights

A patent is a monopoly right granted by statute for the commercial use of an invention for a limited period.³ Patents may only be acquired through registration.

A trade mark indicates the origin of goods and services and may be protected from misuse by third parties, either through rights acquired by registration or through evidence of use.⁴ The protection of a trade mark lasts as long as it fulfils its role as an indicator of origin.

Copyright is a set of exclusive rights granted by statute in relation to literary and artistic creations. It generally lasts for 70 years after the death of the author.⁵ Copyright arises through the act of creation and does not need to be registered.

Trade secrets are confidential business information — such as proprietary methods, customer lists, or manufacturing processes — that provide a competitive advantage.⁶ Trade secrets have no specific duration and subsist for as long as the information remains secret.

Industrial designs protect the ornamental or aesthetic aspects of a product, influencing its visual appeal.⁷ Industrial design rights usually last between 5 and 15 years, depending on the period of extension.

Utility models are similar to patents but cover minor and incremental innovations.⁸ They provide exclusive rights for a shorter period — usually 10 years — and are sometimes referred to as “lesser patents.”

Plant Breeders’ Rights protect new plant varieties, giving breeders exclusive control over the sale and reproduction of those plants.⁹ The duration is usually 20 years.

Geographical indications identify products as originating from a specific geographical area, where the quality, reputation, or characteristics of the product are essentially attributable to that location.¹⁰ This protection ensures that consumers receive authentic, high-quality products associated with a particular region.

Having surveyed the main types of intellectual property rights, we now turn to the type best suited to Mary’s situation and the reasons why.

Why a Patent Is the Best Fit

Section 22 of the Industrial Property Act, Cap 509, Laws of Kenya sets out three requirements that must be satisfied for an invention to be considered patentable:

1. The invention must be new (novelty) — it must not have been disclosed to the public.¹¹
2. The invention must involve an inventive step — it must not be obvious to a person skilled in the relevant field.¹²
3. The invention must be industrially applicable — it must be useful in any form of industry, including, but not limited to, agriculture, medicine, and fisheries.¹³

Additionally, Section 58 of the Industrial Property Act, Cap 509 grants exclusive rights to the patent holder to exploit the invention, precluding unauthorised use and thereby providing both formal legal protection and commercial exclusivity.

The importance of these criteria was affirmed in Pfizer Inc. v Cosmos Limited, Case No. 49 of 2006.¹⁴ In that case, Pfizer filed infringement proceedings before the Industrial Property Tribunal under Section 106 of the Industrial Property Act, alleging that Cosmos was selling Azithromycin dihydrate under the trade mark “Zithrox” without authorisation. The Tribunal found Cosmos Limited in breach of Pfizer’s ARIPO patent number AP44 relating to Azithromycin Dihydrate. Accordingly, the Tribunal issued an injunction restraining the respondent from infringing the patent for the remainder of its term and ordered the destruction of the remaining stock of infringing products. The Tribunal thereby recognised the importance of novelty, inventive step, and industrial applicability in patent protection, and underscored the need to safeguard innovative products that meet the criteria for patentability.

This position was reinforced in Glaxo Group Limited v Syner-Med Pharmaceuticals Ltd (Miscellaneous Application 792 of 2009) [2010] KEHC 4104 (KLR) (4 February 2010). Glaxo Group Limited, as patent holder, filed a case against Syner-Med Pharmaceuticals Ltd alleging breach of its patent concerning a pharmaceutical formulation. Glaxo contended that Syner-Med had manufactured, sold, or distributed a product identical or substantially similar to its patented invention without authorisation. Syner-Med disputed the validity of the patent, arguing that it did not meet the criteria for patentability under the Industrial Property Act, 2001. The court upheld Glaxo’s patent, ruling that it met the statutory criteria under sections 23, 24, and 25 of the Industrial Property Act, 2001. The court further affirmed that a valid patent confers exclusive rights on the inventor under Section 58 of the Act, including the right to exploit the invention, the right to license, and the right to seek legal remedies in the event of infringement.

Mary, as inventor and entrepreneur, has provided a technological solution by originating a device that purifies water using solar energy. Her invention satisfies all three patentability requirements: she describes the device as her original creation; the combination of water purification and solar energy is not obvious to a person skilled in the relevant field; and she has demonstrated that the device can practically address the challenge of water purification. Accordingly, Mary’s invention is patentable, and a patent is the most appropriate form of intellectual property protection for her.

How to Secure Your Invention: Acquiring a Patent

In deciding whether to apply for a patent, a company or individual will consider various factors, including the relative advantages and disadvantages of patent protection compared to other forms of protection — such as the law of confidence and contract law — as well as the strategic commercial value of owning a patent.¹⁵

There are two key advantages to relying on patent law as opposed to the law of confidence or contract law to protect an invention.

• Patent law confers a property right. It confers a right enforceable in rem rather than in personam. A patent owner can therefore exercise her exclusive monopoly rights against third parties.¹⁶
• Patent law protects inventions that are difficult to secure by other means. An invention can easily be discovered by studying a product incorporating it once that product has been released into the market. Patent law provides exclusive rights to the inventor regardless of how the invention is discovered.¹⁷

It is therefore more beneficial for Mary to obtain a patent for her invention in order to secure it and acquire the exclusive rights that flow from it. The following sections explain how a patent may be acquired in Kenya, from application through to grant.

Application

The application process and requirements are set out in Section 34 of the Industrial Property Act, 2001. The application is filed with the Managing Director of the Kenya Industrial Property Institute and must contain the following elements:

• Request. The request shall state the name of, and prescribed data concerning, the applicant, the inventor, and the agent (if any), as well as the title of the invention. Where the applicant is not the inventor, the request must be accompanied by a statement justifying the applicant’s right to the patent.¹⁸
• Description. The description shall disclose the invention and the best mode for carrying it out, in full, clear, concise, and exact terms sufficient to enable a person skilled in the art to make, use, or evaluate the invention. The description must include any drawings and relevant deposits — for instance, in the case of microorganisms and self-replicable material — that are essential for the understanding of the invention.¹⁹
• One or more claims. The claims shall define the matter for which protection is sought and must be clear, concise, and fully supported by the description.²⁰
• An abstract. The abstract serves solely the purpose of technical information. In particular, it shall not be used to interpret the scope of the protection sought.²¹

Where the applicant is a foreign national, he or she must appoint a Kenyan representative, indicated by furnishing a power of attorney signed by the applicant.²²

The applicant may seek to amend the application, provided that the amendment does not go beyond the disclosure in the initial application.²³

The applicant may also claim a priority date under the Paris Convention, based on one or more earlier national, regional, or international applications filed by the applicant or a predecessor in title.²⁴

The applicant is further required to disclose information concerning corresponding foreign applications and grants.²⁵

Upon filing, the applicant must pay the prescribed fees; failure to do so may result in rejection of the application.²⁶

The applicant also has the right to withdraw the application at any time before the grant or notification of rejection.²⁷

Unity of Invention

It is a fundamental principle of patent law that one patent protects one invention, as provided for in Section 35 of the Industrial Property Act, 2001. This is known as the unity of invention. An application must relate to one invention, or to a group of inventions so closely linked as to form a single general inventive concept.

Where an application is found to relate to more than one invention, the application is not automatically invalidated. Instead, the applicant may be invited to rectify the position by deleting some of the claims, amending the claims, or persuading the Managing Director that unity of invention is in fact satisfied.²⁸

Filing Date

The Managing Director shall accord, as the filing date, the date of receipt of the application, provided that at the time of receipt the documents filed contain:

• The name and address of the applicant.
• A part which on its face appears to be a description.
• A part which on its face appears to be a claim or claims.²⁹

If the applicant is invited to make corrections to the application, the date on which the corrected documents are returned becomes the filing date. This also applies in cases involving missing drawings or where corrections are made within a 30-day window.³⁰

The filing date is significant for several reasons: it marks the starting point of the maximum 20-year validity period, establishes when the invention was first disclosed, and assists in determining priority between competing applicants.³¹

Preliminary Examination

Section 41(1)(c) of the Industrial Property Act, 2001 mandates the Managing Director to cause an examination to be carried out to determine whether any of the following defects are present in the application:

1. The request does not comply with the requirements of section 34(3) and the rules pertaining thereto.
2. The description, the claims, and where applicable the drawings, do not comply with the physical requirements prescribed by the regulations.
3. The application does not contain an abstract.
4. The fees referred to in Section 39 have not been paid as provided for in the regulations, or the payment of such fees has not been waived under that section.

Any defect identified at this stage may be remedied without affecting the filing date.

International-Type Search

The Managing Director may instruct that any application be subjected to an international-type search, as provided for in Section 43 of the Industrial Property Act, 2001. The applicant will be invited to pay a fee for this purpose. Upon receipt of the search report, the Managing Director may request the applicant to furnish a copy of any document cited in the report. If the application is found not to relate to a patentable invention, it may be rejected or treated as withdrawn.

Publication of the Patent Application

After 18 months from the filing date or priority date — or earlier, at the applicant’s request — the Managing Director shall cause the patent application to be published in the Kenya Gazette or the Industrial Property Journal, thereby making the invention available to the public.³²

Examination as to Substance

Where an application for a patent satisfies the formal requirements, the Managing Director shall notify the applicant, who must, within five years, submit a request in the prescribed form for substantive examination of the application. This is governed by Section 44 of the Industrial Property Act, 2001 and involves an assessment of:

1. Whether the invention is patentable within the meaning of the Act.
2. Whether the application complies with the requirements of subsections (5) and (6) of Section 34 of the Act.
3. Whether the application complies with the requirement of unity of invention under Section 35.

Any defect identified at this stage may be rectified by amending the application. If not amended, the application may be rejected.

Grant of Patent

Unless an application has been rejected or a patent refused under Sections 41 or 44, a patent shall be granted and issued to the applicant in the prescribed form.³³ Every patent granted shall be registered and shall, as soon as reasonably practicable, be published by the Managing Director in the manner prescribed by the regulations.³⁴

Conclusion

This article has demonstrated that, for an inventor in Mary’s position — having originated a novel, non-obvious, and industrially applicable device for solar-powered water purification — a patent represents the most appropriate and effective form of intellectual property protection under Kenyan law. The Industrial Property Act, Cap 509 provides a clear and structured pathway from initial application to grant, administered by the Kenya Industrial Property Institute. By securing a patent, Mary would obtain an exclusive statutory right enforceable against the world, enabling her to exploit her invention commercially, license its use, and seek legal remedies against any infringement. Understanding this process is vital not only for Mary but for the many innovators across Kenya whose creations deserve formal legal protection.
