Enova Technology Corp (伊諾瓦), a maker of encryption solutions used in hard disks, filed a lawsuit in the US on Wednesday claiming Initio Corp (晶量半導體) and Western Digital Corp had infringed on two of its patents on data encryption.
Hsinchu-based Enova alleged that Western Digital’s sales of its My Book and My Passport brands of external storage devices in the US had infringed on its patents, while Initio had illegally made use of its chip controller patent, especially in a model known as INIC-1607E.
The two patents involve technology for encrypting or decrypting storage media, including disk drives, in a real-time manner without compromising overall system performance, Enova said in a court filing document posted on its Web site.
Enova Technology was founded in April 2000 and has invested significantly in these patent technologies, the company said. Enova founder Wann Shuning “pioneered the development of ground-breaking products, including the first real-time full disk encryption ASIC technology,” it said.
Initio and Western Digital “have ridden on the coattails of Enova’s significant investments in research and development by infringing [on] the patents,” the document stated.
Taipei-based Initio develops semiconductor products such as integrated circuit controllers and software and sells them to companies such as Western Digital, while Western Digital makes storage products for original equipment manufacturers, resellers or retailers.
An official at the office of the president of Initio said by telephone yesterday the company was not aware of the issue and offered no comments.
Robert Blair, a Western Digital spokesman, told Bloomberg it was looking at the complaint and had no comments, either.
Lake Forest, California-based Western Digital, which reported US$7.45 billion in sales for the last fiscal year, plans to spend US$4 billion in the next five years to expand in Asia, Bloomberg said.
Enova’s lawsuit followed in the footsteps of Richtek Technology Corp (立錡), a leading analog IC designer in Taiwan, which filed a patent infringement lawsuit with the US International Trade Commission last week against five companies — including the world’s No. 2 microprocessor maker Advanced Micro Devices Inc, Sapphire Technology Ltd (藍寶科技) in Hong Kong, US-based Diamond Multimedia Inc and XFX Technology Inc, as well as Taiwan’s uPI Semiconductor Corp (力智電子).
Richtek alleged these companies used its business secrets “inappropriately” and had infringed three of its patents.
POOR INTERNAL CONTROLS: Insurance Bureau Director-General Shih Chiung-hwa said the company is expected to get back on track while its chairman is suspended The Financial Supervisory Commission (FSC) yesterday fined Shin Kong Life Insurance Co (新光人壽) NT$27.6 million (US$939,415) for a reckless investment that endangered its solvency, and suspended its chairman Eugene Wu (吳東進) for poor supervision. The penalty is the second-highest in a single case after Nan Shan Life Insurance Co (南山人壽) was fined NT$30 million in September last year and its chairman Du Ying-tzyong (杜英宗) suspended for two years, the commission said. In three rounds of special and regular examinations conducted since last year, the commission found that Shin Kong Life had given too much power to an asset and liability management committee
Tesla Inc is planning to ship vehicles made at its Shanghai Gigafactory to other markets in Asia and Europe, people familiar with the matter said, as the company looks to realize its plan to reduce shipping costs and manufacture vehicles closer to customers. China-built Tesla Model 3s intended for delivery outside China would likely start mass production in the fourth quarter of the year, the people said, asking not to be identified because the details are private. They said the markets targeted include Singapore, Australia and New Zealand, as well as Europe, where customers currently have to wait for a Tesla to
Continental AG, which makes control units for Daimler AG cars, cannot pursue antitrust claims against a group of patent owners, including Qualcomm Inc, which are seeking royalties on telecommunications technology, a federal judge in Texas ruled. Avanci LLC, a licensing pool formed by Qualcomm, Nokia Oyj, Sharp Corp and other owners of patents on technology standards, is not breaching antitrust laws when it negotiates license agreements with automakers rather than the component makers, Barbara Lynn, chief district judge for the Northern District of Texas, said in dismissing the suit in a decision posted on Friday. The licensing group charges US$15 per vehicle
Nano-X Imaging Ltd, a start-up founded by Israeli investor Ran Poliakine, is joining forces with South Korean chipmaker SK Hynix Inc to build a machine that could disrupt a century-old X-ray industry. Valued at about US$2 billion after listing on the NASDAQ last month, Nano-X is seeking to transform a multibillion-dollar industry that has essentially relied on the same technology since Nobel Prize in Physics winner Wilhelm Roentgen discovered X-rays in the late 19th century. Nano-X’s device uses semiconductors instead of metal filaments to generate X-rays. The backing of SK Hynix, the world’s second-largest maker of memory chips, is a boost for
