This study established a technological impact factor (TIF) derived from journal impact factor (JIF), which is proposed to evaluate journals from the aspect of practical innovation. This impact factor mainly examines the influence of journal articles on patents by calculating the number of patents cited to a journal divided by the number of articles published in that particular journal. The values of TIF for five-year (TIF₅) and ten-year (TIF₁₀) periods at the journal level and aggregated TIF values (TIF_{AGG_5} and TIF_{AGG_10}) at the category level were provided and compared to the JIF. The results reveal that journals with higher TIF values showed varied performances in the JCR, while the top ten journals on JIF₅ showed consistent good performance in TIFs. Journals in three selected categories - Electrical & Electronic Engineering, Research & Experimental Medicine, and Organic Chemistry - showed that TIF₅ and TIF₁₀ values are not strongly correlated with JIF₅. Thus, TIFs can provide a new indicator for evaluating journals from the aspect of practical innovation.
