Westminster Magistrates' Court heard how three of the six complainants made claims against him having first been approached by detectives.
His barrister Jonathan Caplan QC asked for details of conversations between police and the women to be revealed.
Mr Fox denies the offences, alleged to have taken place between 1991 and 2014.
The 54-year-old DJ - known as Dr Fox - faces seven charges of indecent assault and two of sexual touching without consent.
He is accused of assaulting girls and women aged between 14 and 36, at locations including the offices of London commercial radio stations Capital FM and Magic FM, as well as at the Chessington World of Adventures theme park.
Westminster Magistrates' Court heard that during the trial witnesses would be called to give evidence via videolink from Australia, and that the complainants would be giving evidence from behind screens.
Mr Fox sat taking notes throughout the administrative hearing.
Details of the charges the Magic FM presenter is accused of have been reported after Mr Caplan asked for the reporting restrictions to be lifted at a previous hearing.
Mr Caplan said there had been a lot of false reports about what his client had allegedly done.
Among the charges, Mr Fox, from Fulham, in south-west London, is accused of repeatedly assaulting a woman at Capital Radio's studios in London's Leicester Square.
Two other women claim to have been sexually touched against their will at Magic FM's premises, in central London, while two girls were allegedly assaulted at a motor show in Bromley, south-east London, in 1991.
Mr Fox, who is is due to stand trial before magistrates on 5 November, was released on unconditional bail.
A further hearing will be held in October.

A late Clint Hill equaliser secured a 1-1 draw at Celtic Park and Murty said the team had proved a point.
"I'm pleased for the players," he said after his last game in charge. "They showed the kind of tenacity and grit that they've been questioned about.
"It's a difficult environment, but two outstanding saves from Craig Gordon or it could have been more."
A Celtic victory would have been their 23rd in succession in the league and their 18th in all competitions.
The Premiership leaders took a first-half lead thanks to Stuart Armstrong's well-taken goal.
Rangers, in front of their new manager, Pedro Caixinha, who was watching from the stands, continued to battle and were rewarded with Hill's 88th-minute goal.
"He saw the players deal with an unbelievable atmosphere," Murty said.
"It takes a real man's performance to play in that and stand up to it.
"I'd been challenging them all week, saying you're the only ones who believe in yourselves.
"They showed that right to the end and I'm proud of them.
"From the moment I saw them at breakfast, I knew they were right where I wanted them to be."
The two Glasgow rivals will meet again in the Scottish Cup semi-final at Hampden Park on 23 April.
Murty, who had gone into the league game with a record of three wins and two defeats in his previous matches in charge, hands over to Caixinha with the side sitting third in the table.
"This should give them lots of confidence," he said.
"They didn't get rattled or lose their discipline.
"We made it difficult for them and put a shift in."
Caixinha will hold a staff meeting at Rangers' Auchenhowie training ground on Monday as he begins his spell in charge of the first-team.
In a message on Rangers' Twitter account, he urged fans to back the team.
"We are doing our very best, in a club like this, to keep up a track of winning," said the Portuguese manager.
"We want a winning mentality. We want a winning team. And you [the Rangers supporters] need to be here to support us."
Murty is expected to return to his role as head coach of the development squad.
DJ Neil Fox has appeared in court accused of nine sex offences over a period spanning more than 20 years ahead of his trial later this year.
