According to TIPO’s 2021 Statistical Rankings for Patent Applications and Grants, TSMC was the top domestic applicant for invention, utility model, and design patents, with 1,950 applications filed. The company has held on to its lead for the sixth consecutive year now. As for foreign applicants, Qualcomm claimed the top spot for the second year in a row, having filed a total of 845 applications. With respect to the number of patents granted for all three patent types, TSMC led the pack for domestic applications (1,053 patents granted), and Applied Materials was the most successful foreign applicant (492 patents granted). Invention patent applications by domestic corporations and research institutions of the top 100 went up by 17% and 11% respectively.

TSMC is top domestic applicant for the sixth year in a row

As regards domestic applicants, TSMC has consistently filed the most applications since 2016. In 2021, that number surged by 78% to 1,950 cases, followed by AU Optronics (471 cases). Realtek Semiconductor (442 cases) and Nanya Tech (290 cases) each filed their highest number of applications ever, coming in fourth and sixth, respectively. Delta Electronics moved back into top 10 with 205 applications (+18%) (Table 1).

The top 100 domestic patent applicants filed 12,234 cases in 2021, a year-on-year increase of 8%. This is mainly driven by a 13% rise in the number of invention patent applications (share of 75%), which came from corporations (+17%) and research institutions (+11%). The filings in design patent applications also grew by 1%. However, the filings in utility model patent applications fell by 7%, mainly due to a decrease of 20% in school applicants (Figure 1, Figure 2).
