After filing a lawsuit against Zillow alleging widespread copyright infringement back in July, CoStar is now claiming that the listing giant has continued to display thousands of copyrighted photographs, despite attestations from Zillow that it was taking the images down. The lawsuit, filed on July 30, alleged that Zillow infringed on at least 47,000 images owned by CoStar. Since that original filing, CoStar claims Zillow has displayed at least 4,618 additional allegedly copyrighted images—most of which feature CoStar’s watermark. “Zillow used our watermarked images, it profited, and—stunningly—it has kept doing it,” said CoStar Group’s General Counsel, Gene Boxer in a statement. Zillow calls itself a tech company, yet supposedly it can’t spot images plainly marked with CoStar Group’s logo.
