The company was a subsidiary of Marex International, an international marine salvage firm located in Memphis, Tennessee. In 1992 Marex made a bid to seize control of the artefacts and the wreck itself by suing Titanic Ventures, arguing that the latter had abandoned its claim by not returning to the wreck since the 1987 expedition. It claimed a superior right of salvage based on a "pill bottle" and hull fragment that were said to have been retrieved by Marex.[137] Marex simultaneously sent a vessel, the Sea Mussel, to carry out its own salvage operation.[138]
