Patentability in Malaysia: What Qualifies as a Patentable Invention?

A Malaysian patent agent's guide to the three patentability criteria under the Patents Act 1983, the Section 13 exclusions, and the practical steps inventors and businesses should take before filing.

Patent protection is one of the most powerful commercial assets a business can hold. A granted Malaysian patent confers a 20-year monopoly over an invention, allowing the patentee to exclude others from making, using, selling or importing the patented product or process within Malaysia. The economic value of that monopoly, particularly for technology businesses, manufacturers and pharmaceutical companies, is often substantial.

Yet a significant proportion of patent applications filed each year never reach grant. Some are refused outright. Many are abandoned mid-prosecution after the applicant realises the cost of fighting examiner objections outweighs the residual value of a narrowed claim set. The common cause is almost always the same: the invention, as filed, did not satisfy the statutory criteria for patentability under Malaysian law.

This article sets out, in practical terms, what those criteria are. It is written for inventors, founders, in-house counsel and foreign IP agents instructing Malaysian patent counsel for the first time. The framework below is drawn from the Patents Act 1983, the Patents Regulations 1986 and the published practice of the Intellectual Property Corporation of Malaysia (MyIPO).

The Three Patentability Criteria

Under Malaysian law, an invention must satisfy three cumulative requirements to be granted a patent. Failure on any one of them is fatal to the application. These are set out in Sections 14, 15 and 16 of the Patents Act 1983 and apply uniformly to national filings, PCT national phase entries and modified substantive examination requests.

1. Novelty (Section 14)

An invention is considered new if it does not form part of the "prior art" anywhere in the world before the filing date of the patent application (or its priority date, where priority is validly claimed under the Paris Convention). Prior art is defined broadly. It includes:

  • Anything that has been disclosed to the public, anywhere in the world, in any form, including patent applications, technical papers, conference presentations, trade shows, product launches, websites and social media posts
  • Public use of the invention, whether commercial or experimental
  • Information contained in earlier Malaysian or foreign patent applications having a filing or priority date before the application in question (so-called "secret prior art")

Malaysia operates an absolute novelty standard. This is stricter than the "local novelty" or "relative novelty" rules of some jurisdictions: a disclosure made anywhere in the world, in any language, before the priority date can destroy novelty.

There is a narrow exception. Section 14(3) provides a 12-month grace period for disclosures made by the inventor (or by a person who obtained the information directly or indirectly from the inventor) within 12 months before the filing date. The grace period does not extend to disclosures made by independent third parties. It should never be relied upon as a substitute for filing before going public.

2. Inventive Step (Section 15)

An invention involves an inventive step if it would not have been obvious to a "person having ordinary skill in the art" having regard to the prior art. The test is hypothetical: the examiner asks whether a skilled practitioner in the relevant field, equipped with knowledge of the prior art but lacking any inventive imagination, would have arrived at the invention as a routine matter.

This is where many applications fail. An invention may be technically novel (no single piece of prior art discloses it) and yet still be obvious in light of the combined teachings of two or more pieces of prior art. The classic patterns of obviousness include:

  • Combining two known elements that perform their ordinary functions, producing a predictable result
  • Substituting one known equivalent for another (a "mere workshop modification")
  • Optimising a known parameter (size, dosage, temperature) within an obvious range
  • Applying a known principle from one technical field to an adjacent field, where the application is foreseeable

Demonstrating inventive step often requires showing an unexpected technical effect: a result the skilled person would not have predicted from the prior art. Comparative experimental data, secondary indicia such as commercial success or long-felt need, and expert affidavits can all be deployed in response to inventive-step objections during examination.

3. Industrial Applicability (Section 16)

The invention must be capable of being made or used in any kind of industry, including agriculture. This is a low bar in practice. Almost any product or process other than a pure abstraction (a mathematical proof, a philosophical theory) will satisfy it. The provision exists primarily to exclude pure intellectual exercises and aesthetic creations that have no industrial application; those are addressed through other regimes such as copyright or designs.

What Is Not Patentable: The Section 13 Exclusions

Even where an invention satisfies the three core criteria, it must also fall within the categories of patentable subject matter. Section 13 of the Patents Act 1983 expressly excludes the following from patent protection:

Section 13 ExclusionWhat it covers in practice
Discoveries, scientific theories & mathematical methods Newton's laws, a newly identified naturally occurring chemical compound (in its natural state), a novel mathematical algorithm or proof. The discovery is not patentable; a practical industrial application of it sometimes is.
Plant & animal varieties; biological processes Excludes new plant varieties (protected separately under the Protection of New Plant Varieties Act 2004) and essentially biological processes for breeding plants or animals. Micro-organisms, micro-biological processes and the products of such processes remain patentable.
Schemes, rules & methods for doing business, performing mental acts or playing games Pure business methods (a novel pricing model, a marketing strategy), board game rules, methods of meditation. The closer a claim is to abstract human behaviour or commerce, the more likely it falls here.
Methods of medical treatment Methods for the surgical, therapeutic or diagnostic treatment of the human or animal body. Importantly, products used in such methods (a new drug, a surgical device) remain patentable.

What about software?

Computer programs are not expressly excluded from patentability under Malaysian law (unlike Article 52 of the European Patent Convention). However, software-related claims may still fail under Section 13(a) if they amount to no more than an abstract algorithm or mathematical method, or under Section 13(c) if they claim a method of doing business or performing mental acts dressed up in technical language.

The decisive question for software inventions is whether the claim defines a technical solution to a technical problem: improving processor efficiency, controlling a physical system, encoding data more reliably. Where it does, grant is achievable. Where the technical wrapper is thin and the substance is a business or mental method, the application will struggle. Careful claim drafting by a registered Malaysian patent agent is essential in this area.

Patent or Utility Innovation? Choosing the Right Right

Malaysia is one of a small number of jurisdictions that offers a second tier of protection alongside full patents. The utility innovation, governed by Part XVA of the Patents Act 1983, is Malaysia's equivalent of the petty patent or utility model found in many civil-law jurisdictions.

The key differences:

PatentUtility Innovation
RequirementsNovelty + inventive step + industrial applicabilityNovelty + industrial applicability only (no inventive step)
Term20 years from filing10 years from grant, renewable in two 5-year blocks to a maximum 20 years
Number of claimsMultiple independent and dependent claims permittedOne independent claim only
Filing & prosecution costHigher (official fees + agent fees + likely office actions)Lower (single claim, simpler examination)
Typical use casePharmaceuticals, chemistry, complex mechanical or electronic inventions, softwareIncremental improvements, simple mechanical innovations, low-inventiveness improvements that nonetheless satisfy novelty

The utility innovation is often overlooked. For inventors and SMEs whose innovation is genuinely new but might struggle to demonstrate non-obviousness against the prior art, it offers a faster, cheaper route to enforceable protection. A registered Malaysian patent agent can advise on which route is appropriate for a particular invention.

Common Pitfalls That Kill Patent Applications

The most common reasons applications fail are not legal subtleties. They are avoidable practical mistakes made before filing.

  • Public disclosure before filing. The single most expensive mistake. A trade show presentation, a press release, a patent-relevant LinkedIn post, a journal abstract: any of these can destroy worldwide novelty. The 12-month grace period under Section 14(3) provides limited relief, and only for the inventor's own disclosures.
  • Filing without a prior art search. A pre-filing search identifies the closest prior art, allows the claims to be drafted around it, and avoids spending years prosecuting an application that was always going to fail.
  • Claims drafted too broadly. Broad claims attract broad prior art and broad objections. Skilled drafting balances breadth (commercial value) against narrowness (chances of grant).
  • Confusing “improvement” with “invention”. Many businesses describe their product as an improvement over what exists. The patent question is whether the improvement is also non-obvious in light of the prior art.
  • No technical effect in software claims. Drafting software inventions without identifying the specific technical problem solved leaves the claim vulnerable to Section 13 objections.
  • Inadequate documentation. Inventor's notebooks, dated emails, internal technical reports. These become crucial if priority or inventorship is later challenged.

A Pre-Filing Checklist

For inventors and businesses considering a Malaysian patent application, the following steps materially strengthen the prospects of grant and enforceability:

  1. Document the invention in writing. A clear, dated technical description signed by all inventors, retained in the company's records.
  2. Maintain confidentiality. Non-disclosure agreements with anyone shown the invention; a clear "do not publicly disclose" policy until filing.
  3. Conduct a prior art search. Patent databases such as Espacenet, Google Patents, USPTO, and the MyIPO IP Online portal. A focused search by a patent agent typically takes a few hours and pays for itself many times over.
  4. Identify the technical problem and the technical effect. Especially critical for software, methods, and incremental inventions.
  5. Choose the right filing route. National Malaysian filing, PCT international application, or utility innovation, depending on commercial geography and budget.
  6. Consider priority strategy. Under the Paris Convention, a Malaysian filing can serve as the priority document for foreign filings within 12 months. Where global protection is contemplated, the order and timing of filings matter.
  7. Engage a registered Malaysian patent agent before any public disclosure. Most jurisdictions, Malaysia included, require non-resident applicants to act through a registered local patent agent under the Patents Act 1983.

From Filing to Grant

Once a Malaysian patent application is filed, it follows a structured path:

  1. Filing & formality examination: typically within 1-3 months of submission. MyIPO verifies that the application meets basic formal requirements.
  2. Publication: 18 months after the priority or filing date. The application is published in the official journal and becomes available to the public.
  3. Request for substantive examination: must be filed within 18 months of the filing date. The applicant may opt for full substantive examination or modified substantive examination (where a corresponding patent has already been granted in a recognised jurisdiction).
  4. Substantive examination & office actions: MyIPO examiners assess the application against the patentability criteria. Office actions are common; responses must be filed within the statutory deadline (typically 2-3 months, extendable).
  5. Grant or refusal: if the application meets all requirements, the patent is granted and published. If not, the applicant can appeal to the High Court under Section 88.

The total timeline from filing to grant typically runs 3-5 years for a national application. Modified substantive examination, where available, can shorten this considerably.

The Practical Takeaway

Patent protection rewards careful preparation. The criteria are not designed to be hard for the sake of it. They exist to ensure that the 20-year monopoly is granted only to inventions that genuinely advance the state of the art. Applicants who file early, file with a clear understanding of the prior art, and draft claims with both breadth and defensibility in mind, are the applicants who walk away with enforceable rights.

For Malaysian inventors and businesses, patent protection sits within a wider intellectual property toolkit that also includes trademark registration, industrial designs, copyright and trade secrets. A coherent IP strategy considers all of these together, allocating each form of protection to the asset it best fits.
