* Ciena of Linthicum was granted one injunction and denied another in a long-standing patent-infringement case against Corvis, its Columbia-based rival in making fiber-optic network equipment. A U.S. District Court judge in Delaware last week blocked Corvis from using a technology a jury previously determined Corvis did not have the right to use. Corvis said the injunction that was granted would not affect its business because it no longer sells products using the technology. Ciena, whose founder left to start Corvis, sued Corvis in 2000 for infringing four patents. A Ciena spokesman said it was considering further legal options. Litigation in the case may continue for a year or more, and damages would be awarded only after the case concludes.
