Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) remained the top invention patent applicant in Taiwan in the first quarter of this year, outpacing all local and foreign applicants, the Intellectual Property Office said on Thursday.
TSMC filed 752 invention patents, up 4 percent from a year earlier, marking the fourth consecutive year the chipmaker claimed the first place in the first quarter.
Patents are categorized into three groups in Taiwan: invention, design and utility model. Invention patents are considered the most important in terms of new technology ideas.

Smartphone IC designer MediaTek Inc (聯發科) took second place among local applicants with 146 invention patent applications, up 121 percent from a year earlier, the highest rate of growth among local firms.
DRAM chip supplier Nanya Technology Corp (南亞科技) was third with 115 invention patent applications, up 17 percent from a year earlier, followed by flat-panel makers Innolux Corp (群創) and AUO Corp (友達), which filed 101 and 94 applications, up 3 percent and 7 percent respectively.
The office said it was the first time Innolux has filed more than 100 invention patent applications in a single quarter.
Rounding out the top 10 local applicants were communication network IC designer Realtek Semiconductor Corp (瑞昱半導體), with 77 applications, down 28 percent; contract notebook computer maker Inventec Corp (英業達) with 55 applications, up 17 percent; Chunghwa Telecom Co (中華電信) with 45 applications, up 50 percent, memorychip supplier Macronix International Co (旺宏電子) with 42 applications, down 9 percent; and the government-sponsored Industrial Technology Research Institute with 42 applications, up 5 percent.
Among foreign applicants, Applied Materials Inc reclaimed the top spot after nine years by filing 182 invention patent applications, down 12 percent from a year earlier. It was followed by Japanese electrical product maker Nitto Denko Corp with 176 applications, up 18 percent; US-based smartphone IC designer Qualcomm Inc with 169 applications, down 30 percent; South Korea’s Samsung Electronics Co with 166 applications, up 44 percent; and Japanese semiconductor supplier Tokyo Electron Ltd with 128 applications, down 10 percent.
In the first quarter, 12,486 invention patent applications were filed, little changed from a year earlier, the office said.
The number of invention, utility model and design patent applications totaled 17,226 in the first quarter, down 2 percent from a year earlier, it added.
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
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
Taiwan is open to joining a global liquefied natural gas (LNG) program if one is created, but on the condition that countries provide delivery even in a scenario where there is a conflict with China, an energy department official said yesterday. While Taiwan’s priority is to have enough LNG at home, the nation is open to exploring potential strategic reserves in other countries such as Japan or South Korea, Energy Administration Deputy Director-General Chen Chung-hsien (陳崇憲) said. While the LNG market does not have a global reserve for emergencies like that of oil, the concept has been raised a few times —
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.
