Oracle, IBM, SAP and Adobe Systems are the latest targets of patent lawsuits filed by Implicit Networks.
Implicit claims the companies "are violating two patents for computer-server software that performs faster security functions". Implicit filed its lawsuit July 15.
According to news agency Bloomberg, Implicit is seeking royalties from such products as IBM's Websphere Application Server, Oracle's Application Server and BEA WebLogic Server, SAP's NetWeaver and Adobe's JRun and ColdFusion. The suit centres around two patents issued to Implicit after applications filed by the company in 1998 and 2001.
