According to Article 12 of the Law on Patents and Utility Model Registration, the legal protection of a patentable invention is granted by means of a patent. A patent attests the exclusive right of the owner on the invention. The term of validity of a patent is 20 years from the date of filing of the application. The advantage of the protection of the invention is that the owner is entitled to prohibit the use, import, sale of the protected work or the application of the patented method in the country. The owner may also use the invention as well as authorize others to use the invention.
Patents are granted for inventions in any field of technology, which are new, involve an inventive step and are susceptible of industrial application.

Novelty – the invention shall be considered to be new if it does not form part of the state of the art. The state of the art shall be held to comprise everything made available to the public by means of a written or oral description, by use, or in any other way, anywhere in the world, before the filing date or the priority date, as appropriate, of the patent application. Inventive step – the invention shall be considered to involve an inventive step if, having regard to the state of the art at the filing date or the priority date, respectively, it is not obvious to a person skilled in the art. Industrial application – the invention shall be considered susceptible of industrial application if its subject matter can be made or used repeatedly in any branch of industry or agriculture.

Depending on its territorial validity the patent may be registered as a national patent, European patent and international patent.
