Abstract-Intellectual property rights (IPR) of computer software is the right to assign the software to its creator, not limited to time and space, and non-transferable. Proving IPR of the creators of computer software requires a rigorous review of the ways in which these rights may be violated. The present study was conducted by comparing two populations in Iran with the aim of identifying the level of familiarity and observance of software IPR: 1) 96 software engineers member of IEEE Association and 2) 386 students randomly. Results are analyzed by SPSS software and the validity of the results is verified using T-test. By comparing the results, it was concluded that the first population significantly observed these cases more. Then a model was presented for protecting software IPR so that the challenges are reduced. This research is the completion of our previous work that was discussed as a future work.
