What is a patent?

A patent is an exclusive right granted for an invention, a product or a process that provides a new way of doing something or a new technical solution to a problem. A patent owner has the right to decide who may – or may not – use the patented invention for the period in which the invention is protected. In other words, patent protection means that the invention cannot be commercially made, used, distributed, imported, or sold by others without the patent owner's consent. The exclusivity rights are territorial rights, limited to the country were the patent has been validated, and limited to 20 years upon filing the patent application and upon payment of yearly maintenance fees. To get a patent, technical information about the invention must be disclosed to the public in a patent application.

What can be patented?

New products, processes and technologies, used for a new purpose with new unique properties, chemical substances or mixtures, pharmaceuticals, industrial micro-organisms and combinations thereof. In addition to novelty (i.e. not previously published), the products, processes and technologies have to inventive (if the invention is obvious or trivial, you cannot get a patent) and industrially applicable.

What cannot be patented?

Discoveries or scientific theories, computer programs (in CZ), board games, mathematical methodologies, new plant varieties, animal breeds, ways of treating or healing people and animals, diagnostic methods, aesthetic creations, plans, rules and methods of performing mental activities, performance of commercial activities, supplying information, and anything else in conflict with public policy and accepted ethical principles.

Who grants patents?

The Industrial Property Office of the Czech Republic (IPO CZ) grants patents valid in the territory of the Czech Republic. The European Patent Office grants European patents (covering a territory larger than the EC countries), but once granted this patent has to be validated in each European country of choice, resulting in a bundle of national patents. The IPO CZ will for example validate the European patent in the Czech Republic.

National application submission

  • A request for grant of a patent carries out by patent application. You can use an electronic form or collect a printed form at the Industrial Property Office of the Czech Republic. Czech is the official language of the IPO CZ, therefore the forms are available in Czech only. Please, note that persons not having the domicile or headquarters on the territory of the Czech Republic, must be represented in the proceedings before the Office by a representative.
  • Electronic forms (without on-line filling option) - Forms in pdf format, that can be filled out electronically and then printed.

International submission

You can apply for a patent with international permission in three ways:

  • National submission - The applicant creator may subscribe any invention directly in state he wants to have the invention protected.
  • European patent application - Applies in the states that are members of the European Patent Organization (EPO). Applications in these members can be filed in any language. However, the official languages of the EPO are English, French and German. If the application is not filed in one of these languages, a translation has to be submitted. You can submit an application at the Czech IPO as well.
  • International application PCT - Gets the protection in the 146 states and includes four regional patents (within European patent). Applications can be filed at the Czech IPO in English, German or French language and application form must be in the same language.


  • Patent search - Before applying for a patent, it is advisable to carry out a patent search, if our invent is patentable.
  • Patent application submission
  • Filing and formalities examination - Involves checking whether all the necessary information and documentation has been provided.
  • Preliminary research - Patent office retrieves all the documents available that may be relevant to assessing novelty and inventive step and does the search report.
  • Publication of an application - At the least 18 months after the date of filing is an application published in IPO Bulletin.
  • Substantive examination - Patent office examines whether the patent application and the invention meet the requirements and a patent can be granted. Proprietor or applicant creator has 36 months after an application submission to submit a request for a survey of patentability.
  • Grant of a patent - Patent granted in the Czech Republic is valid for 20 years from the filing of the application.
  • Publication of a patent - A patent effectivity comes on publication of granting a patent in the Bulletin of the Industrial property office.
  • Opposition - In the case of an appeal or review of the decision of the Office.

Administrative Fees

Fees depends on the territorial (Czech patent, European patent or International patent), and other factors. In the Czech Republic, the price of a patent is around 10 000 Czech crowns.

Geographical denominations and appellations of origin

  • Appellation of origin is the name of a region, a specific place or a country. Product quality or other characteristics are essentially or exclusively given by a particular geographical environment with its inherent natural and human factors and the production and preparation takes place in a delimited geographical region.
  • Protected geographical indication is the name of a region used for products originating in that region and also with characteristics exclusively given by that region.

Industrial designs

  • Industrial design is understood to mean appearance of a product or its part, consisting particularly of signs of lines, contours, colors, shape, material structure of the product per se or ornamentation. Industrial design can be protected if it is new and has individual character. This protection guarantees for proprietor the exclusive right to use, protect before its usage by third parties without proprietor agreement, provide agreement to usage by other persons (licences) or proprietor has the rights to assign it (e.g. sell). Max. term of protection for an industrial design shall be 25 years.

Supplementary protection certificates (SPC)

  • Provides for active substances, medicaments or preparations the extended term of protection after the expiration date of the patent, because they have longer approval process. Maximum validity of a patent is extended for about 5 years to 25 years.

Topographies of Semiconductor products

  • The manufacture of the integrated circuit is the basic solution in the semiconductor industry, which has the features of the creative work and must be protected against pirating. For registration of topography of a semiconductor product into the State register may occur only by applications filed in the IPO CZ. However, the protection rights for topography may be applied only by citizens of the Czech Republic or people with residence. Others only under the condition of reciprocity.


  • The trademark means a signification of a graphic visualization, in particular by words, letters, numbers, shapes of the colours, drawings or forms of the product or its packages, designed to the products or services resolution. The trademark proprietor gets the exclusive rights to its use with registration. The validity of a trademark is about 10 years from the date of filing of the application. The validity can be extended by another 10 years due to the request for renewal of a trademark filed within the statutory time limit.
  • Trademarks registered in the Czech Republic can also be registered through the IPO CZ as so-called international trademarks in some other states.

Utility models

  • Utility models are the new, industrially usable technical solutions. However, all of the methods of production or work activity and biological reproductive materials are excluded from the protection. The registration process takes usually from three to four months after the filing of the application. The Office examines only the compliance of the basic conditions for protection and writes the utility model to the index. Max. validity is about 10 years.
  • The application for a utility models, applies a similar principles, as in the case of a patent application. This application is an ideal solution for inventions with a shorter life span, because the effects of the registration of a utility model are the same as the effects of a patent. The conditions for registration are the novelty of the product and its industrial utility.

Reference resources

Patent databases and other intellectual property documents are provided by national and international patent offices. In most cases, they provide the full-text documents. Be aware that databases contain all published patent applications, granted, rejected or terminated (due to the end of the 20-year protection or non-payment of yearly maintenance fees). A granted patent may have a different patent number (for example US patents have a publication number such as US20157654321 and a patent number such as US12345678. The EPO distinguishes pending/non-granted patent by the letter “A” at the end of the patent number, and granted patents by the letter “B” at the end of the patent number.
