It is one of the most important rules in patent law. In simple terms, it means that an invention must be completely new anywhere in the world before it can be protected by a patent. If the invention has already been made public – in any country – before the patent application is filed, it usually cannot be patented. This rule helps ensure that patents are only granted for truly new ideas and not for things that are already known.
What Does “Absolute Novelty” Mean?
Imagine you invent a new type of gardening tool and tell your friends about it, post photos online, or demonstrate it at a public event. Even if you have not sold the product yet, the invention is no longer considered new because it has been publicly disclosed. Under the principle of absolute novelty, any public disclosure anywhere in the world counts, whether it happens in South Africa, Europe, the United States, or online. This includes:
- Publishing details in a newspaper, journal, or website
- Demonstrating the invention at a trade show or exhibition
- Selling or offering the product for sale
- Posting information on social media
- Filing a patent application that later becomes public
Once information about the invention is available to the public, it becomes part of what patent law calls the “prior art” – meaning existing knowledge.
Why Absolute Novelty Is Important
The purpose of absolute novelty is to keep the patent system fair and encourage genuine innovation. Patents give inventors exclusive rights to use and profit from their inventions, often for up to 20 years. Because this protection is powerful, the law requires that the invention must be truly new and not something the public already knows about.
Without the rule of absolute novelty, people might try to patent ideas that are already in use or widely known. This could block others from using common technology and slow down progress.
Absolute Novelty in Everyday Terms
A simple way to understand absolute novelty is this: “If the public already knows about it, you cannot patent it.” Even a small disclosure can matter. For example:
- Showing your invention to the public before filing a patent application
- Publishing a description of the invention in a brochure
- Selling a prototype before applying for a patent
Any of these actions can destroy novelty and prevent a patent from being granted.
Does Absolute Novelty Apply in South Africa?
Yes. South Africa follows the principle of absolute novelty, similar to many other countries around the world. This means that an invention must be new on a global scale, not just new within South Africa. However, South Africa’s patent system is sometimes described as a “deposit system.” This means the patent office does not fully examine whether an invention is new before granting the patent. Instead, novelty is often tested later, for example if the patent is challenged in court or during enforcement. Even so, the legal requirement for absolute novelty still applies.
Are There Any Exceptions?
In some countries, there is a limited grace period, usually about 6 to 12 months, during which an inventor can disclose the invention and still file a patent application. These exceptions are narrow and vary from country to country. In South Africa, the grace period is limited and should not be relied on without professional advice. The safest approach is always: File the patent application before making the invention public.
Practical Tips for Inventors and Businesses
For anyone developing a new product, process, or technology, a few simple precautions can help protect patent rights:
- Keep the invention confidential until a patent application is filed
- Use non-disclosure agreements (NDAs) when sharing information
- Avoid publishing or marketing the invention too early
- File a provisional patent application as soon as possible
- Keep records of development dates and testing
These steps are especially useful for entrepreneurs, inventors, and small businesses who may be working on new technologies or products.
Absolute novelty means that an invention must be completely new anywhere in the world before a patent can be granted. If the invention has been publicly disclosed – even once – before filing a patent application, it usually cannot be patented. The rule encourages genuine innovation and protects the integrity of the patent system.
In everyday language: “Keep it secret until you file.”
