*5.2.3. Corporation*

Corporation's prominent performance in both PPCI and HFPPCIs could be seen in **Figures 11**–**13** in which most disciplines were located on the first quadrant. It was also interesting that all three figures showed a correlation between the two indicators, except for two disciplines (engineering and physics) in **Figure 11**. Therefore, three indicators functioned robustly, regardless of the limited number of papers cited in high-feature-valued patents and corporation's relatively small share of publications in Japan.

Engineering and physics showed opposite impacts in LPFPCI (**Figure 11**) compared to HFCPCI (**Figure 12**) and HGPCI (**Figure 13**). They showed very low values of LPFPCI and limited number of papers cited in large-sized patent families. However, they showed high values of both HFCPCI and HGPCI and relatively large numbers of papers which were cited in patents with the top 1% patent-patent forward citations and with high patent generality index. Although further analysis was needed to show the correct factors of the phenomenon, this might be caused by characteristics of the industries which cited these disciplines.
