There is no global patent! You or your representative must ensure that you file an application with each national patent office whose protection you wish to obtain and/or the European Patent Office. Make sure you do so in time!
If you have already filed a patent application or utility model application in a given country (e.g. Austria), as of the date of application (priority date) you have twelve months (priority year) to file an application for your invention in any other country. Your original filing date (priority date) can be taken with you.
1. Individual applications
If, for example, you only wish to cover the German-speaking countries or only wish to export to the USA or China, you can file individual applications with the given national patent offices. If, however, you wish to cover the European area or keep your options open, you have the possibility of filing a collective application.
2. European or Collective applications
To save the effort of filing individual national applications, there is the possibility of filing a European or an international application (PCT). The Patent Prosecution Highway (PPH) can help you to get international protection faster.

Tip: Internationalization is expensive. The search result of a prior national patent application or prior utility model application at the Austrian Patent Office can provide you with information on whether a collective application is worthwhile. It also provides you with an internationally valid priority date for a period of 12 months.
