License & Technology
The principal commission of Licensing and Technology of Iran Itok Engineering Company is obtaining and transfer of know-how needed for applying systematic and new methods of optimization of the processes of the project, controlling, and increasing the added value.
The activities of the Office are done in following ways:
  • Solving the processing problems of the projects and improving the existing processes.
  • Identification and purchasing the needed patents
  • Obtaining know-how and licenses needed by the projects and the different units of the company.
  • Gathering the relevant scientific information through attending in national and or international congresses, seminars, and conferences that result in transfer of desired scientific information and experiences.
Among the sources used by the Office for gathering the information are the scientific sites existing in Internet, plants, essays of scientific journals, essays presented to the congresses and conferences, different researches and reports, and employing professional forces.
The indicators used for purpose of measuring the degree of achievements are:
  • Input/output ratio that is controlled by the multitude of the information fed into a project and the saved time to the expected amount.
  • The Projects Problems Removal is controlled by the ratio of the solved problems to total problems.
  • The ratio of the number of the essays presented to scientific gatherings to the number of the congresses, conferences, and seminars that relate to the projects of the company.
  • Ratio of the used technology to obtained technology
