Semiconductor supplier Analog Devices Inc. has filed a patent infringement lawsuit against Xilinx, Inc., charging that the company violated ADI’s patents relating to converter technology in at least two of Xilinx’s High End Zynq UltraScale+ RFSoC products.
In the lawsuit, filed in the United States District Court for the District of Delaware, Analog Devices said the complaint focuses on eight patents related to analog-to-digital converters (ADCs). The two companies are no strangers to one another, collaborating for years on ADCs.
According to the filing, “Xilinx has been a significant beneficiary of ADI’s substantial and continuing investments in analog-to-digital conversion technology. ADI has worked closely with Xilinx for many years to develop proven solutions tailored to Xilinx’s field-programmable gate array (FPGA) products, including Xilinx’s Kintex 7 and Kintex UltraScale products, its Virtex 7 and Virtex UltraScale products, its Zynq 7 products, and its initial Zynq UltraScale products.”
The filing also stated, “Over the course of the parties’ collaboration, ADI has shared with Xilinx, under a non-disclosure agreement, extensive and detailed technical information concerning its many innovations in ADC technology.”
In the patent suit, Analog Devices contends that Xilinx violated its patents related to its Zynq UltraScale + RFSoC products, extensively incorporating its proprietary and patented technologies.
As of early Thursday, Xilinx has not yet responded.
“ADI is a market leader in analog, mixed-signal and power integrated circuit technologies and has one of the leading patent portfolios in the semiconductor industry,” said Larry Weiss, Senior Vice President and General Counsel, Analog Devices, in a statement. “We have built this global leadership position through the diligent work of our employees throughout our company’s 55-year history, and our continued investment in research and development which totaled over $1 billion in the last fiscal year. We are committed to defending and protecting our intellectual property, which creates long-term value for all our stakeholders.”
