The Florida based company's Mac Manager provides desktop security and personal-data management capabilities to Macintosh users. On the market for six years, it restricts access to applications, documents and network resources.
However, since 1999 Mac Manager has also been the name of Apple's workstation-management technology that configures and controls Macs running on networks.
Apple stands accused of "wilfully infringing ELS trademark right" by using an identical name for similar software. ELS is alleging dilution, unfair competition and injury to business reputation.
According to MacCentral reports, ELS president, Mitchell Martin, has had to deal with complaints about Apple's product directed to him due to the confusion.
