OAPI has a depository patent filing system. OAPI patent applications are not subjected to substantive examination. As a result, the cost of obtaining a granted patent in OAPI is relatively low and no examination or final grant fees are payable. OAPI is a member of the Paris Convention and the PCT. The deadline for filing PCT national phase applications is 30 months from the earliest priority date. The OAPI Registrar of Patents has not discretion to extend the national phase entry deadline as the South Africa registrar.

What is a patent ?

A patent is a limited monopoly granted by the OAPI to an inventor, or other person entitled to the invention, in exchange for a full disclosure of the invention to the public. This monopoly entitles the patent holder to prevent others from using the invention in any practical manner for the duration of the patent, so that only the patent holder enjoys any profit or advantage that the invention affords for the period. After expiry of the period members of the public are free to use the invention.

Is my invention patentable ?

To be patentable in OAPI an invention must be new, involve an inventive step and must be capable of being applied in industry.

means that the invention has not been made available to the public anywhere in the world – by word of mouth, by use, in any printed publication, or in any other way – before a first application is made for a patent. It is difficult to establish whether an invention is in fact new, but novelty may be assessed by carrying out searches through existing printed publications that include previously published patent specifications.
“The invention must involve an inventive step”
means that the invention must not be obvious to a person of ordinary skill in the art to which the invention relates. Put differently, the invention must not be so similar to what was available or used previously that it required little or no ingenuity to make the invention; that is to say, it must involve an inventive step. For example, it would be obvious to make an article that was previously made exclusively of metal in a plastic material, if there were no special and unforeseeable advantages to making it in plastic.

The invention must be capable of being applied in industry, in trade, or agriculture.

In addition to the above three requirements there are certain “inventions” which cannot be patented in OAPI. The most important of these are pure business methods and computer programs. This prohibition, however, does not extend to inventions that merely make use of business methods or computer programs, while not constituting business methods or computer programs as such. We urge you to contact us if you are uncertain as to whether an invention constitutes a pure business method or computer program. Lastly, a method of treatment of the human or animal body by surgery, therapy or diagnosis is not patentable in OAPI.

How long does a patent last ?

An OAPI patent lasts 20 years from the date of application, subject to the payment of annual renewal fees.

How easily can someone else get around my patent?

The scope of protection afforded by a patent is defined by the patent claims. A well-drafted set of patent claims will prevent others from being able to reverse-engineer the invention by including or excluding inessential features while still using the basic idea of the invention. This is why the use of patent attorneys who are experienced in the drafting of patent specifications is so important.  

What can I do with a patent?

A patent is property and may be sold (by way of assignment) or licensed for use by others. Alternatively, a patent can be used defensively to prevent others from exploiting the invention, provided the patent holder exercises the invention to an adequate extent.

How do I apply for a patent?

A patent application is made by filing a patent specification, together with the necessary forms and government fees, at the Patent Office. The patent specification, which includes a description of the invention as well as any drawings which may be necessary for a clear understanding of the description. If the invention is not yet in its final form it is preferable to file a provisional patent application first, and then a complete patent application within 12 months, because improvements made to the invention can be incorporated into the complete patent specification. A complete application may be in the first instance if sufficient information about the invention and its implementation is available. If given a description of the invention, we will prepare the patent specification and the necessary forms and file a patent application on your behalf. All the administrative functions will be carried out by our offices. 

How do I get patents in other countries?

A patent application must be filed in each country in which protection is sought. However, in respect of most countries in the world, corresponding foreign patent applications can be filed within 12 months from the first patent application in terms of the Paris Convention.

The Patent Cooperation Treaty (PCT) provides a mechanism to delay the filing of individual foreign applications by a further 18 months, and also provides a facility for tailoring a patent specification according to the results of an international search and examination. Should you require patent protection in more than 2 or 3 foreign countries, we usually recommend filing a PCT patent application, unless it is essential that granted patents be obtained in the foreign countries as soon as possible. A PCT application must be filed within 12 months from the date of first filing a patent application, regardless of whether the first patent application is an OAPI patent application.

What are the costs involved?

The cost involved in preparing and filing a provisional or complete patent application will vary from case to case and will depend on the length of the patent specification. Our charges are very competitive and we encourage you to contact us with details of your invention to enable us to provide you with an estimate of the costs involved.

Non- patentable objects in OAPI

  • Discoveries
  • Scientific theories
  • Mathematical methods
  • Aesthetic creations
  • Business methods, schemes or rules
  • Schemes, rules or methods for playing games or performing mental acts
  • Computer programs
  • The presentation of information
  • Animals or plants or biological (not microbiological) processes for the production of animals or plants
  • Methods of treatment of the human or animal body by surgery, therapy or diagnosis

In the case of business methods and computer programs, the restriction only applies to cases where the patent relates to such invention as such, not to cases where the invention merely includes such an invention. Unfortunately our courts have not yet had the opportunity of interpreting this section, but we expect that the interpretation applied to the patentability of computer programs and business methods will probably be similar to that followed in the European Patent Office and other jurisdictions having similar prohibitions. We would therefore suggest that a decision as to whether to apply for patent protection in OAPI should be based on the same considerations that apply to obtaining patent protection in the EPO. Although methods of treatment of the human or animal body are not patentable in OAPI, this restriction does not apply to an invention comprising a new substance for use in a method of treatment. It also does not apply to inventions comprising a known substance for use in a new method of treatment, provided the substance has not been used in any such method. First medical use claims are therefore allowable, but it is not yet clear whether second medical use claims will be enforceable.
