The study proposes a new indicator, the Relative Technology Factor (TFR), to measure a journal's technological impact based on citations in patent applications. The TFR considers factors like the GDP of countries where patent protection is sought and the number of cited references in a patent family, but correlates weakly with existing scientific impact indicators.

The work was financed by the Spanish government and the European Regional Development Fund. This does not automatically imply a conflict of interest, but it is worth noting as a potential source of bias.

This paper presents a novel approach to measuring technological impact, but several methodological limitations and the observed instability of the indicator warrant a moderate rating. The limitations of the dataset, the citation window, and the skewed distribution of scores, along with the low correlation with established metrics, prevent a higher rating. While the funding source is noted, it does not appear to represent a direct conflict of interest with the research topic.
