Understanding patents

An invention uses technology to solve a specific problem. The invention can be a product, such as goods, tools, and materials, or a process, such as manufacturing processes and control procedures. 

A patent is an intellectual property (IP) right to legally protect technical invention. A patent offers many benefits. It allows the patent holder to prevent others from using his/her invention for commercial purposes for up to 20 years. The patent holder can decide who is allowed to produce, sell or import the invention. The patent holder can also trade the patent, e.g. sell it or licence the use of the invention through a license agreement. In return for patent protection, the technical details of the invention must be disclosed to the public during patent application.

Patents may be granted for inventions of technical character, if the invention is new, involves an inventive step and has industrial applicability. There are some exceptions to patentability, however, mainly in the field of biotechnology and medical treatment. In many countries, software or procedures based on computer programs can be protected only if they contain further technical elements. This means that program-​​controlled equipment, procedures for production and control of procedures can be patented as a rule. In some countries, for example the US, the possibility of patent protection is broader. In any case, software is protected by copyright.

To patent, it is important that your invention is new. As a rule, you will know the scientific literature of your field very well, but what about the patent literature? You may consult various patent databases on the Internet in advance to find out whether patents already exist for inventions which resemble your own or concern a similar problem.
