Choose protection by asking what the customer is buying
A patent and an industrial design protect different things. A patent is directed to a technical solution: how a product or process works. An industrial design is directed to the product’s outward visual appearance. A manufacturer may need both, but one registration cannot be stretched to do the other’s job. Start by separating the technical features from the visual features before discussing forms, fees or filing routes.
Consider a water filter with a new cartridge mechanism and a distinctive housing. The mechanism may justify a patent application if it meets the statutory tests. The housing’s shape, line pattern or ornament may support a design application if it is new. The name used on the filter belongs in a trade mark analysis, while manufacturing drawings, tolerances and test data may also require contractual and trade-secret controls. The commercial asset is therefore a bundle, not a single certificate.
The choice affects disclosure, cost, evidence and enforcement. Patent drafting must define the technical monopoly in claims and disclose the invention sufficiently. Design filing depends heavily on accurate visual representations and the product’s overall appearance. A rushed filing can preserve the wrong feature while public demonstrations, tenders, social-media launches or distributor samples destroy the novelty argument for the feature that really matters.
Stop uncontrolled disclosure before the novelty search
Before filing, make a disclosure map. List every pitch, exhibition, prototype trial, crowdfunding page, quotation, tender, university presentation, supplier drawing and sale. Record the date, audience, material shown and any confidentiality restriction. Kenya’s novelty rules look beyond the Kenyan market, so an earlier online video or foreign catalogue can matter even if the product has never been sold locally.
Use written confidentiality terms with engineers, fabricators, testing laboratories, investors and potential licensees. Limit documents to what each recipient needs, watermark sensitive versions and keep a release register. Confidentiality is not a substitute for filing, but it reduces accidental disclosure and helps prove how information was controlled. The trade-secret guide explains the separate protection strategy for know-how that should remain undisclosed.
If disclosure has already occurred, do not conceal it from the patent agent or advocate. Identify exactly what the public could learn and compare it with the intended claims or design representations. A confidential factory trial is not automatically equivalent to a public sale, and a photograph showing only the exterior may not reveal an internal mechanism. The correct response depends on the evidence, not on relabelling an inconvenient event.
Patentability requires a technical invention and three separate tests
Part III of the Industrial Property Act deals with patentability. Sections 21 and 22 frame an invention and patentable inventions. Sections 23, 24 and 25 address novelty, inventive step and industrial application. These are cumulative requirements. A product can be commercially attractive yet fail because the claimed subject matter is already known, is an obvious development for the relevant skilled person, or is not capable of industrial use.
Section 26 excludes specified subject matter from patent protection. The label placed on the project does not decide the issue. A business method described as a “system,” a discovery presented as a product, or a treatment method rewritten as a workflow still requires a proper statutory analysis. KIPI’s official patents guidance also distinguishes technical inventions from excluded subject matter and explains the main application components.
A prior-art search should be directed by the proposed technical features, not only by the product name. Search patent classifications, claim language, technical papers, catalogues and relevant market material. Record the search strings, databases, dates and the closest documents. The purpose is not to promise that nothing similar exists; it is to identify the strongest earlier disclosures, improve the claim strategy and prevent money being spent on an application that cannot support a useful commercial boundary.
The patent specification is a legal and engineering document
KIPI states that a complete patent application includes a request on Form IP 3, a detailed description, one or more claims, drawings where necessary and an abstract. The description should enable a person skilled in the field to evaluate and understand the invention. The claims define the matter for which protection is sought and must be clear, concise and supported by the description. A marketing brochure rarely meets those functions.
Prepare an invention record before drafting. It should identify the problem, essential components, how they interact, preferred and alternative versions, test results, materials, operating ranges, drawings and known weaknesses. Distinguish indispensable features from convenient ones. If the only example is drafted too narrowly, competitors may design around it. If the claims are broader than the disclosure or prior art permits, examination and later validity become harder.
KIPI’s guidance recognises provisional and complete applications. A provisional filing can establish an early filing position, but KIPI states that the complete application must follow within twelve months or the provisional application is treated as withdrawn. A thin provisional document may not support later claims merely because it carries an early date. The first filing should therefore describe the actual inventive concept with enough technical substance to justify the priority later claimed.
Industrial design protection begins with the images
Section 84 of the Industrial Property Act concerns the special appearance given to an industrial or handicraft product by visual features. Protection does not extend to a feature serving solely to obtain a technical result. KIPI’s industrial-design guidance describes the right as protection for outward appearance or “eye appeal,” not the method of construction or function of the article.
Section 86 requires novelty. Kenyan decisions applying the section explain that prior public disclosure anywhere in the world, through publication or use, can defeat novelty where the earlier appearance is identical or substantially similar in overall impression. Run image searches, catalogue checks and competitor-product reviews before settling the filing. Preserve the closest results so the designer can explain which visual choices create the distinct overall impression.
The representations should show the same product consistently. Decide whether colour is claimed, which views are needed, whether surface pattern matters and whether a background, shadow, label, connector or internal component creates ambiguity. Do not submit a mixture of prototype versions. Where several materially different appearances are planned, assess them separately rather than assuming one image set will cover an entire product family.
Ownership must be resolved before an application is signed
The person who generated the concept, the company that paid for development and the party entitled to file may not be the same. Record each contributor’s work, dates and employment or consultancy status. Review employment clauses, commissioned-design terms, university policies, grant conditions, joint-development agreements and earlier assignments. An invoice for engineering services does not necessarily transfer every intellectual-property right.
Sections 30 to 33 of the Industrial Property Act contain the framework for entitlement to inventions, including employee-made inventions and the naming of inventors. Section 85 applies relevant entitlement principles to industrial designs. The filing record should correctly identify inventors or creators while separately documenting ownership and any assignment. Removing a real contributor to simplify a corporate narrative can create a later challenge.
If two companies collaborated, settle ownership before commercial launch. The agreement should address filing control, prosecution costs, territories, improvements, access to technical information, licensing authority, enforcement decisions and what happens when the collaboration ends. Register or record changes in ownership where the applicable procedure requires it, and ensure that the applicant name is consistent across the application, supporting documents and corporate records.
Build the filing route around markets, not prestige
A Kenyan registration is territorial. KIPI expressly notes that a Kenyan industrial design does not itself give protection abroad, although a Kenyan application may support a priority claim in a later foreign application. Patent protection is also territorial. List the countries where the product will be manufactured, sold, licensed or exposed to copying, then compare filing routes, priority deadlines, translation needs and realistic budgets.
Do not confuse an international application with a worldwide right. Regional or international filing systems can coordinate parts of the process, but national or regional requirements, examination, fees and enforcement still matter. Obtain a route analysis before the first priority period starts to run. A late decision cannot recreate a missed priority claim or erase an intervening disclosure.
For a functional improvement that may not justify a full patent strategy, consider whether a Kenyan utility model fits. KIPI’s utility-model guidance states that qualifying subject matter must be new and industrially applicable, that the certificate runs for ten years from grant without renewal, and that conversion between a patent and utility-model application is possible before grant or refusal, subject to the statutory process and fees. Utility model treatment should be assessed on its own facts, not marketed as an automatic “small patent.”
Prosecution is a managed evidence process
After filing, keep the filing receipt, application number, exact submitted documents, payment proof and a frozen copy of every representation or drawing. Calendar the complete-application date for a provisional filing, priority dates, requests from KIPI, publication events, opposition windows, examination correspondence, grant steps and renewal or annual-fee dates. The applicable notice and current regulations determine the response required; a generic diary entry such as “renew IP yearly” is unsafe.
The Industrial Property Regulations prescribe forms and procedural details. For industrial designs, regulation 52 addresses renewal procedure under section 88, including Form IP 32. The Act provides an initial five-year design term from filing and permits two further consecutive five-year renewals on the prescribed process. A design can therefore reach fifteen years, but only if renewal is handled correctly.
Respond to an examiner’s objection by analysing the cited material and the commercial objective. A claim amendment may obtain grant but surrender the feature that gives the product its value. A change to design representations can create a mismatch with the marketed item. Keep a prosecution note explaining why each amendment was made, what coverage remains and whether product development or a fresh filing is needed.
Commercial agreements should match the registered boundary
Before licensing, compare the final claims or registered representations with the product actually supplied. Define the licensed rights, application or registration numbers, territory, field of use, exclusivity, sublicensing, royalties, improvements, quality control, marking, confidentiality and responsibility for prosecution and renewal. The IP licensing guide covers the wider agreement architecture.
A licence should not promise monopoly over unprotected ideas. Patent claims may cover one mechanism but not the complete machine. A design may cover one appearance while a licensee expects an entire brand family. Attach the correct schedules and state how future applications and variants are handled. If manufacture requires undisclosed tolerances or recipes, license the registered right and the controlled know-how as distinct assets.
Record revenue and product versions from launch. Keep batch photographs, packaging, invoices, distributor territories, technical change notices and licence reports. These records help prove use, identify which version embodies the right and calculate loss if copying occurs. They also prevent a later argument that the owner cannot connect a certificate to the product sold in the market.
Prepare infringement proof as a feature comparison
For a patent, obtain the granted claims and map each required claim element against the accused product or process. Avoid treating similarity of purpose as proof. Lawfully acquire and preserve a sample, manuals, advertisements, import records and technical evidence. Expert assistance may be necessary where an internal process cannot be inferred from the exterior.
For an industrial design, compare the registered representations with the accused product’s overall visual appearance. Keep multiple views, packaging and purchase evidence, but do not let logos or colour distract from the registered features. In Kenrub Limited v Metro-Poly Kenya Limited, the Industrial Property Tribunal examined the statutory separation between protected visual appearance and features serving solely to obtain a technical result, as well as novelty and registration.
Before sending a demand, test ownership, status, renewals, claim scope, validity risks, licences, exhaustion and the alleged acts in Kenya. A weak threat can provoke a revocation or invalidation challenge. Coordinate notices, interim relief and commercial remedies through the IP enforcement guide, and quantify damages from actual sales, margins, licence evidence and causation rather than assuming the value of the registration.
Bring a decision file, not only an idea
Request a Kenyan patent or industrial design review with a plain-language invention or design summary, dated drawings, prototype versions, contributor list, employment and consultancy agreements, disclosure history, closest prior art, intended markets, launch date and budget. The review should decide what deserves protection, who may file, what must remain confidential and which deadlines control the sequence.
The most useful outcome is not the largest number of applications. It is a filing plan tied to a defensible technical or visual boundary, reliable ownership evidence and the markets that justify the expense. That discipline also makes licensing clearer and enforcement less vulnerable to an avoidable novelty, entitlement or representation problem.
Frequently asked questions
Should I file a patent or an industrial design for a new product in Kenya?
Use the feature being protected as the starting point. A patent addresses a qualifying technical invention and must meet novelty, inventive-step and industrial-application requirements. An industrial design protects a new outward visual appearance, not a construction method or a feature serving solely to obtain a technical result. A product may justify both filings, supported by separate descriptions and evidence.
Can I show the invention to investors before filing at KIPI?
Public disclosure can damage novelty, so the safest sequence is to assess and file before an unrestricted pitch, sale, exhibition or online launch. If disclosure is necessary, use written confidentiality controls and keep a precise record of what was shown. Tell the patent agent or advocate about every earlier disclosure because its legal effect depends on the content, audience and circumstances.
How long can an industrial design remain protected in Kenya?
The Industrial Property Act provides an initial five-year period calculated from the filing date and permits two further consecutive five-year renewals through the prescribed procedure, giving a possible total of fifteen years. The owner must calendar the current renewal requirements and fees; a certificate does not maintain itself automatically.
