District Judge Sanders threw out the cases, which were prosecuted by the Federation Against Copyright Theft (FACT), after trials in Bury and St Helens Magistrates Courts on 22, 23 and 24 August.
After dismissing the prosecutions District Judge Sanders criticised FACT for bringing “sloppy prosecutions”.
Emmanuel Gabriel of the Spanking Roger in Miles Platting, Manchester and Paul West of Blessed Sports Bar in St Helens, Merseyside were all charged with six offences, while Michael Dwyer of the Peel Hotel in Bury, Lancashire was charged with seven offences.
FACT was unwilling to comment when contacted by the Publican’s Morning Advertiser.
However a Sky spokesman said: “Licensees should be aware that the only way to show Sky broadcasts to the public is via a commercial agreement with Sky and users of any other unauthorised system will be subject to legal action.
"Sky will continue to protect the interests of our legitimate subscribers by supporting FACT in prosecuting licensees who break the law.”
Speaking after the trials Paul Dixon of Molesworths Bright and Clegg, the solicitors representing the three licensees, said: “These prosecutions were flawed from the outset.
“I am delighted to have secured acquittals for my clients so that they can now concentrate on what they do best - looking after customers.”
