Tessera Technologies Inc, the maker of chip-packaging technology for companies including Intel Corp, has sued more than a dozen companies it says refused to license its patented technology.
Companies including Nanya Technology Corp (南亞科技) and Elpida Memory Inc have "chosen to disregard Tessera's rights," Tessera said on Friday in a US federal court complaint. "They have made, and continue to make, extensive and profitable use of Tessera's patented advances without fairly compensating Tessera."
The San Jose, California-based company also has pending pantent-infringement claims against Qualcomm Inc, Freescale Semiconductor Inc and Motorola Inc.
Royalties and licensing fees accounted for 84 percent of its third-quarter revenue.
The litigation is a way to push more companies to license Tessera patents. The company said last month license revenue surged 60 percent in the third quarter and projected that fourth-quarter sales would exceed analysts' expectations on new licensing agreements.
The companies that were sued, besides Nanya and Elpida, include Acer Inc and ProMos Technologies Inc (
Semiconductor packages protect the chips from damage, stress and contamination. Tessera said its packaging allows chips to be made smaller for electronics, medical devices and military components.
