The High Court in the United Kingdom has approved the Premier League's application to block pirated streams of matches via Kodi set-top boxes.
The court order means the Premier League can now block the computer servers that power the illegal streams, rather than just individual streams.
A spokesperson said: "For the first time this will enable the Premier League to disrupt and prevent the illegal streaming of our matches via IPTV, so-called Kodi, boxes.
"This will enable us to target the suppliers of illegal streams to IPTV boxes, and the internet, in a proportionate and precise manner."
The Premier League TV rights for 2016-19 sold for £5.136 billion in 2015.
A Sky spokesperson said in the Daily Telegraph: "We are pleased the Premier League's application to crack down on illegal streaming has been granted. Content piracy is theft and the success of this application is an important step in tackling the issue.
"We'll continue to work with rights holders, government, online market places and content creators to tackle today's piracy and make people aware of the risks it presents and the damage it causes."
Kodi boxes, popular in Britain, can be used to access the pirated material and people have been arrested for selling boxes that are modified to allow users to do so.
However, a spokesperson for Derbyshire Trading standards told the Derby Telegraph this week that users are not likely to be guilty of breaking UK copyright law simply by watching streams.
The spokesperson said: "Kodi is a legitimate piece of software and the developers do not support its use for illegal purposes, but Derbyshire County Council trading standards officers believe it is illegal under copyright legislation to sell Kodi boxes installed with those add-ons that facilitate the illegal streaming of copyrighted material -- although there are court cases pending elsewhere in the UK that will provide further clarification.
"Accessing premium paid-for content without a subscription is considered by the industry as unlawful access, although streaming something online, rather than downloading a file, is likely to be exempt from copyright laws."
