Singapore property portal PropertyGuru is suing rival 99.co over copyright infringement in a matter which will next be heard in the High Court on Sept 20.
A writ of summons is a court document to start civil legal proceedings in Singapore.
PropertyGuru has filed three claims against 99.co.
Firstly it claims that 99.co breached a settlement that both parties entered into in September 2015.
99.co has denied all claims and filed a counterclaim against PropertyGuru, reported Channel NewsAsia.
Property agents have been using a third-party app called Xpressor, which allows cross-posting.
PropertyGuru claims that property agents posted their listings on 99.co using the app, but 99.co said in its counterclaim that property agents were merely “exercising their own copyright” in doing so.
PropertyGuru started in 2007 and boasts the largest number of listings in Singapore with some 15,000 agents using the platform.
