CoStar amended its copyright infringement lawsuit against Zillow, alleging the platform has used more than 53,000 watermarked rental property photos without permission. According to CoStar's amended complaint, the alleged infringement extends across Zillow and its syndication partners.
The lawsuit centers on rental property listings, a key battleground as both companies compete for market share in the residential rental sector. CoStar's complaint suggests the scope of alleged infringement has expanded significantly since the initial filing.
