of 39 as presented on Fig. 1). Having in mind that this is significant share, patents of contemporary Serbian inventors and scientists in this field are presented in Table 1, as they contribute to the life and safety of structures. In addition, this work complements the research on the continuity in the application of exceptional technical solutions of Serbian scientists in the field of civil engineering, namely previous research which covers achievements of Roger Boscovich at the end of the 18 th century, then Milutin Milanković at the turn of the 19 th and 20 th century, Branko Žeželj in the second half of the 20 th century, and contemporary inventors and scientists with significant achievements in the 21 st century (Jelić, 2017a; Jelic 2017b). In that respect, and having in mind that Branko Žeželj was one of the founders and long-time principal of the Institute for TestingMaterial of the Republic of Serbia (IMS Institute), this work gives overview of the application of patented inventions created in 21 st century of two Serbian scientists and civil engineers Zoran Petrašković PhD and Nenad Šušić PhD, who have gained p rofessional experience in the IMS Institute.

Fig. 1. The comparative overview of the number of patents in the period from 1998 to 2017 in the area of seismic reliability of structures and rebuilding landslide granted by the EPO for the inventions of inventors from Europe with the number of patents granted by the IPORS for inventions of Serbian inventors (Extracted from Espacenet) Furtermore, Zoran Petrašković is inventor of the half of the patented inventions granted by the Intellectal Property Office of the Republic of Serbia (IPORS) in the period from 1998 to 2017 (Table 1). Inventions of Nenad Šušić are protected with petty patent, and therefore are not visible in Table 1, which presents granted patents for inventions of Serbian inventors. Neverthel es, achievements of Nenad Šušić are significant, and application of his patented inventions which were created in 21 st century are presented in the third part of this work. Creation of invention is based on the date of filling of patent application, and da ta about patented inventions of Zoran Petrašković and Nenad Šušić are extracted from Serbian national patent data base MIMOSA RS.

Overview and application of patented inventions of Zoran Petrašković Zoran Petrasković gained part of his professional experience in the IMS Institute , from 1998 to 2005 (Petrašković, 2013), and his patented inventions in the field of seismic reliability of structures are in use worldwide (http://dc90.co.rs/). Furtermore, he is founder of SYSTEM DC90 Company for research, consulting, engineering and technology transfer, with main activity in the remediation, reconstruction and seismic protection of structures under construction and also of erected structures (http://dc90.co.rs/about-us.html). The DC 90 System is also a market name
