An article from 2005 outlining APBs plans re the 777,

As APB nears the 767 winglet launch, it is looking at wingtip treatments for the 777-200ER. The wingtip shape could either be a winglet or a "spiroid", which is a closed loop winglet. APB has a patent on this design.
"We hope to have a firm configuration by the fourth quarter and would like to be in a position to offer this modification to the market at that time," says Marino, with a launch customer signed up within a year.
If this goes to plan, APB could see the first 777 with winglets or spiroids entering service in mid-to-late 2007. If the spiroid design is chosen the company may have to develop a proof-of-concept flying demonstrator, which would most likely be on a 737 testbed.
