Intellectual Ventures, a patent holding company established by former Microsoft chief technology officer Nathan Myrhvold, has filed 3 patent infringement lawsuits against nine security chip making and memory solutions firms.
The company, which invests in innovative technologies and licenses them to firms, has accused security software vendors McAfee, Trend Micro, Symantec and CheckPoint Securities for infringing on four patents related to anti-virus and security technology it owns in the first lawsuit.
The second suit has been filed against Altera, Lattice Semiconductor and Microsemi Corp, which make FPGA (Field-Programmable Gate Array) logic chips. The lawsuit accused them of infringing on up to 5 patents.
The final lawsuit has targeted Hynix Semiconductor and Elpida Memory, which make DRAM (Dynamic Random Access Memory) and Flash memory peripherals, accusing them off infringing on 5-7 patents.
The cases have been filed in a Federal Court in Delaware and claim that all defendants were earlier asked to purchase the licenses for the technologies they were unlawfully using.
