Realtor.com Parent Files Suit Against CoStar, Claiming Theft of Proprietary Information

ā€œThis is a PR stunt that is already backfiring. Realtor.com is losing the battle with Homes.com, and its attempt to change the story doesn't change that reality. We look forward to prevailing in court,ā€ a CoStar spokesperson told RISMedia.

NAR Objects to DOJ Filing, Claiming It Will ā€˜Harm Consumers and Reduce Access to Fair Housing’

Mere weeks after the Realtor.com and Homes.com CEOs hurled hurled insults and accusations at each other as the residential real estate portal giants fight for second place behind Zillow, the battle was ratcheted up further on July 2 when Realtor.com parent Move, Inc. filed a lawsuit in the U.S. District Court in California, claiming that a former Move employee now working for Homes.com parent CoStar Group stole proprietary information helping Homes.com expand its burgeoning business.

Move, owned by the Rupert Murdoch-led media company News Corp, wrote in its complaint that James Kaminsky, ā€œa former Move employee now working for Move’s direct competitor, CoStar, systematically invaded Move’s secure computer systems, secretly exfiltrated Move’s trade secrets, and spied on Move’s real-time confidential electronic documents to give CoStar a massive unfair competitive advantage and to help CoStar increase traffic to its competing real estate listing website, all to the detriment of Move.

ā€œThere is nothing wrong with lawful – even intense – competition. But competitors should never be allowed to cheat and steal to get ahead.ā€

Move is requesting a jury trial and damages.

In an emailed statement to RISMedia, Co-Star scoffed at the charges and vowed to fight them in court.

ā€œThis lawsuit is Realtor.com’s latest desperate attempt to distract from the fact that Homes.com has replaced Realtor.com as the number two portal according to the parties’ own site-centric data gathering tools,ā€ wrote Gene Boxer, general counsel.Ā 

ā€œThe employee in question is a mid-level manager who writes and edits stories about condos. Safe to say he has zero input into Homes.com’s strategy. And even Move’s creative writing exercise doesn’t pretend that CoStar itself engaged in any misconduct. This is a PR stunt that is already backfiring. Realtor.com is losing the battle with Homes.com and its attempt to change the story doesn’t change that reality. We look forward to prevailing in court.ā€

The claim made specific allegations about how Kaminsky assisted Homes.com and illegally hurt Realtor.com.

ā€œRealtor.com has succeeded in building up significant website traffic, and it uses various marketing strategies to increase and maintain that traffic, including traditional advertising on television and across the Internet. Realtor.com also relies on a strong, established and successful ā€œNews & Insightsā€ platform as part of its product offering and to attract real estate professionals, consumers and other visitors to Realtor.com. The platform is featured prominently on the Realtor.com website.Ā 

ā€œThe News & Insights team publishes quality content, working with groups across the Realtor.com business and with others in the media to report and comment on real estate and related topics. News & Insights is key to building Move’s and Realtor.com’s brand awareness, goodwill and loyalty.Ā 

ā€œCoStar apparently wants to create a rival News & Insights platform for Homes.com, copying the success of the News & Insights team at Realtor.com. CoStar recently hired the former head of Realtor.com’s News & Insights group, Defendant James Kaminsky. For nearly a decade, Mr. Kaminsky led Realtor.com’s News & Insights group, with knowledge of nearly every facet of the business, including strategy, organizational structure and operational details. He has referredĀ  to the News & Insights group at Realtor.com as ā€˜an essential branding and monetization engine for Realtor.com.’

ā€œNow at CoStar, Mr. Kaminsky is managing a team of writers, just as he did at Realtor.com. He holds himself out as a ā€œContent Strategist,ā€ ā€œSenior Editorial Director,ā€ ā€œTeam Leader,ā€ and ā€œBrand Builder.ā€ According to his LinkedIn profile, Mr. Kaminsky’s new employer is ā€œCoStar,ā€ and his new title is ā€œEditor, Homes.com.ā€ Mr. Kaminsky now manages and supervises a team of 10 other employees at CoStar working to build up a new digital product similar to Realtor.com’s News & Insights platform.

ā€œIn June 2024, Move discovered that CoStar, through its employee, Mr. Kaminsky, has been brazenly and repeatedly misappropriating Move’s confidential and trade secret information to give Homes.com a massive jump start in setting up its new offering. As he departed Move, Mr. Kaminsky stole confidential business information, sending it to his personal email account on the last day he had access to Move’s computer system. He established surreptitious, undetected ongoing access to allow himself (and, thus, CoStar) to spy on Move’s highly confidential documentsĀ  stored on protected computer systems.Ā 

ā€œThen, attempting to cover his tracks, Mr. Kaminsky deleted nearly a thousand files from his Move computer and wiped clean his entire browsing history before returning the device to Move. Since he left Move, for several months including a significant period of time in which he was with CoStar, until he was recently caught red-handed, Mr. Kaminsky unlawfully exploited ongoing access to Move’s confidential and trade secret information which was being updated by unsuspecting Move personnel in real-time.ā€
