Third, the total number of citations varies substantially. In line with its importance in patenting activity, Electronic & Electric has the most citations, followed by Industrial Equipment, Chemicals, and Instruments. This might result from the large number of patents this sector develops compared to others. Patents in Main Components and Cell System are, on average, more likely to be cited than those in Peripheral Components and Battery Integration. As the sectors mentioned obtain large numbers of patents in the first two technology architecture categories, this might even reinforce the effect that their high totals have on their citations.
