Taiwanese handset camera lens maker Largan Precision Co (大立光) has sued Samsung Electronics Co in a US district court, accusing the world’s largest smartphone maker of infringing on six patents Largan registered in the US, according to a copy of court papers the Taipei Times received yesterday.
In the complaint filed on Thursday last week in the US District Court in the Southern District of California, Largan also sued Samsung Electronics America Inc and Samsung Telecommunications America LLC, two subsidiaries of Samsung that sell and offer a variety of consumer electronics, as well as personal and business communications devices in the US.
Largan claimed the patent infringements by Samsung have led to “foreseeable harm and injury” to the company and it was seeking unspecified compensation and an immediate end to such infringements.
“Largan has become aware that many of Samsung’s mobile phones, such as the Galaxy Note II, incorporate inventions covered by one or more of Largan’s patents,” the company said in the complaint.
The company said it had notified Samsung several times this year in January, February, August and September with letters, e-mails and claim charts that it was infringing Largan’s patents.
“Despite being aware of Largan’s patents and Largan’s infringement allegations, Samsung has continued selling the infringing devices” in the US, the complaint said.
The latest patent litigation came after the Greater Taichung-based company filed a lawsuit against domestic rival Ability Optoelectronic Technology Inc (先進光電) last month for stealing trade secrets.
In June, Largan also sued another domestic rival, Genius Electronic Optical Co (玉晶光), for patent infringement.
The lawsuit against Samsung would be a different battle than others as the South Korean firm held a market capitalization of 219.33 trillion won (US$207.71 billion) yesterday, 43 times bigger than Largan’s market value of NT$142.86 billion (US$4.85 billion).
Moreover, Samsung is also one of Largan’s clients. In July, Largan chief executive officer Adam Lin (林恩平) said the firm had begun shipping camera lenses to the South Korean firm.
Largan said it has developed a portfolio of patents to address the need for imaging lenses, which are used in cameras for a wide range of devices including mobile phones, tablets, notebook computers, webcams, cars and scanners.
The patents-in-suit are Patent No. 7262925 for an image lens array; Patent No. 7394602 for an optical system for capturing images; Patent No. 7898747 for a thin-type optical lens system for capturing images; Patent No. 8154807 for imaging lens assembly; Patent No. 8284291 for optical lens assembly; and Patent No. 8508860 for an optical lens system.
Largan’s shares rose 5.97 to NT$1,065 yesterday. They have risen 36.89 percent so far this year.
Shares of contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) came under pressure yesterday after a report that Apple Inc is looking to shift some orders from the Taiwanese company to Intel Corp. TSMC shares fell NT$55, or 2.4 percent, to close at NT$2,235 on the local main board, Taiwan Stock Exchange data showed. Despite the losses, TSMC is expected to continue to benefit from sound fundamentals, as it maintains a lead over its peers in high-end process development, analysts said. “The selling was a knee-jerk reaction to an Intel-Apple report over the weekend,” Mega International Investment Services Corp (兆豐國際投顧) analyst Alex Huang
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is expected to remain Apple Inc’s primary chip manufacturing partner despite reports that Apple could shift some orders to Intel Corp, industry experts said yesterday. The comments came after The Wall Street Journal reported on Friday that Apple and Intel had reached a preliminary agreement following more than a year of negotiations for Intel to manufacture some chips for Apple devices. Taiwan Institute of Economic Research (台灣經濟研究院) economist Arisa Liu (劉佩真) said TSMC’s advanced packaging technologies, including integrated fan-out and chip-on-wafer-on-substrate, remain critical to the performance of Apple’s A-series and M-series chips. She said Intel and Samsung
TRANSITION: With the closure, the company would reorganize its Taiwanese unit to a sales and service-focused model, Bridgestone said Bridgestone Corp yesterday announced it would cease manufacturing operations at its tire plant in Hsinchu County’s Hukou Township (湖口), affecting more than 500 workers. Bridgestone Taiwan Co (台灣普利司通) said in a statement that the decision was based on the Tokyo-based tire maker’s adjustments to its global operational strategy and long-term market development considerations. The Taiwanese unit would be reorganized as part of the closure, effective yesterday, and all related production activities would be concluded, the statement said. Under the plan, Bridgestone would continue to deepen its presence in the Taiwanese market, while transitioning to a sales and service-focused business model, it added. The Hsinchu
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has approved a capital budget of US$31.28 billion for production expansion to meet long-term development needs during the artificial intelligence (AI) boom. The company’s board meeting yesterday approved the capital appropriation plan for purposes such as the installation of advanced technology capacity and fab construction, the world’s largest contract chipmaker said in a statement. At an earnings conference last month, TSMC forecast that its capital expenditure for this year would be at the higher end of the US$52 billion to US$56 billion range it forecast in January in response to robust demand for 5G, AI and
