Abstract
The study establishes three synthetic indicators derived from academic traces—assignee traces T1, T2 and ST—and investigates their application in evaluating technological performance of assignees. Patent data for the top 100 assignees in three fields, “Computer Hardware & Software”, “Motors, Engines & Parts”, and “Drugs & Medical”, were retrieved from USPTO for further analysis. The results reveal that traces are indeed valid and useful indicators for measuring technological performance and providing detailed technical information about assignees and the industry. In addition, we investigate the relationship between traces and three other indicators: patent citation counts, Current Impact Index and patent h-index. In comparison with the three other indicators, traces demonstrate unique advantages and can be a good complement to patent citation analysis.
