Artifacts have been periodically salvaged from the wreck between 1987-2000. RMS Titanic Corp now has title to those artifacts and has periodically talked about returning to the wreck to salvage more. The whole thing has been tied up in court cases since the 1987 expedition, which is par for the course with international maritime salvage.
