Iomega Corp has reached for its lawyers again and is suing its biggest rival Syquest Technology Inc, claiming Syquest’s removable storage products infringe its read/write protection patents and Jaz cartridge designs. Iomega, which has bounced back to prominence with its eponymous Jaz and Zip removable hard drives for disk-hungry PCs, also wants to stop Syquest using ‘syJet’ in its advertising material. JET is an Iomega trademark. In May, Iomega accused Nomai SA of Avranches, France, of copying its Zip drive formats (CI No 3,155). Syquest has already charged Nomai with patent, copyright and trademark infringement, breach of contract and unfair competition for copying its exchangeable disk drives (CI No 3,079).
