Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, filed the most patent applications among all local and foreign applicants in the first quarter of this year, the Intellectual Property Office said on Friday.
Among foreign applicants, US-based smartphone IC designer Qualcomm Inc was the largest patent applicant in Taiwan from January to March, the office said.
Data compiled by the office showed that in the first quarter, TSMC filed 723 invention patents, a quarterly high for the chipmaker since the office began tallying patent applications in 2012.

TSMC’s first-quarter patent applications for inventions rose by about 7 percent from a year earlier, reflecting the chipmaker’s efforts to upgrade its technologies and maintain its lead over peers.
Taiwanese law has three categories for patents — invention, utility model and design.
Invention patents are considered the most important in the technology sector.
Communication network IC designer Realtek Semiconductor Corp (瑞昱半導體) was second among Taiwanese companies after filing 107 invention applications in the first quarter, down by 4 percent from a year earlier, ahead of flat-panel maker Innolux Corp (群創光電) with 98, memorychip supplier Nanya Technology Corp (南亞科技) with 98, and flat-panel maker AU Optronics Corp (友達光電) with 88.
Smartphone IC designer MediaTek Inc (聯發科) was sixth with 66 invention patent applications in the first quarter, followed by PC brand Acer Inc (宏碁) with 63, contract electronics maker Wistron Corp (緯創) with 58, contract notebook computer maker Inventec Corp (英業達) with 47 and memorychip maker Macronix International Co (旺宏電子) with 46, the data showed.
Qualcomm filed 242 invention patent applications in the first quarter as the top foreign applicant, up 13 percent from a year earlier, the office said.
US semiconductor equipment supplier Applied Materials Inc was second among foreign invention patent applicants with 206 applications, up by 61 percent from a year earlier, followed by Japanese electrical product maker Nitto Denko Corp with 149, Japan-based semiconductor supplier Tokyo Electron Ltd with 142, and Japanese memorychip supplier Kioxia Holdings Corp with 134, the office said.
US-based semiconductor giant Intel Corp filed 71 invention applications in the first quarter. While Intel is in ninth place among foreign applicants, its applications increased year-on-year by 914 percent, the office said.
In the first quarter, 12,534 invention patent applications were filed, up 5 percent from a year earlier, while the number of applications from foreign entities rose by 10 percent to 7,837, the office said, adding that local applications fell to 4,697 from 4,742, the office said.
The number of invention, utility model and design patents filed in Taiwan reached 17,498 in the first quarter, up 2 percent from a year earlier, it said.
Singapore-based ride-hailing and delivery giant Grab Holdings Ltd has applied for regulatory approval to acquire the Taiwan operations of Germany-based Delivery Hero SE's Foodpanda in a deal valued at about US$600 million. Grab submitted the filing to the Fair Trade Commission on Friday last week, with the transaction subject to regulatory review and approval, the company said in a statement yesterday. Its independent governance structure would help foster a healthy and competitive market in Taiwan if the deal is approved, Grab said. Grab, which is listed on the NASDAQ, said in the filing that US-based Uber Technologies Inc holds about 13 percent of
The domestic unit of the Chinese-owned, Dutch-headquartered chipmaker Nexperia BV will soon be able to produce semiconductors locally within China, according to two company sources. Nexperia is at the center of a global tug-of-war over critical semiconductor technology, with a Dutch court in February ordering a probe into alleged mismanagement at the company. The geopolitical tussle has disrupted supply chains, with some carmakers reportedly forced to cut production due to chip shortages. Local production would allow Nexperia’s domestic arm, Nexperia Semiconductors (China) Ltd (安世半導體中國), to bypass restrictions in place since October on the supply of silicon wafers — etched with tiny components to
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday received government approval to deploy its advanced 3-nanometer (3nm) process at its second fab currently under construction in Japan, the Ministry of Economic Affairs said in a news release. The ministry green-lit the plan for the facility in Kumamoto, which is scheduled to start installing equipment and come online in 2028 with a monthly production capacity of 15,000 12-inch wafers, the ministry said. The Department of Investment Review in June 2024 authorized a US$5.26 billion investment for the facility, slated to manufacture 6- to 12nm chips, significantly less advanced than 3nm process. At a meeting with
Taiwan’s food delivery market could undergo a major shift if Singapore-based Grab Holdings Ltd completes its planned acquisition of Delivery Hero SE’s Foodpanda business in Taiwan, industry experts said. Grab on Monday last week announced it would acquire Foodpanda’s Taiwan operations for US$600 million. The deal is expected to be finalized in the second half of this year, with Grab aiming to complete user migration to its platform by the first half of next year. A duopoly between Uber Eats and Foodpanda dominates Taiwan’s delivery market, a structure that has remained intact since the Fair Trade Commission (FTC) blocked Uber Technologies Inc’s
