Real Estate Intelligence: The Billion-Dollar Case for Invisible Watermarking

The Staggering Financial Stakes

The numbers tell a compelling story. In July 2025, CoStar Group filed what it calls "one of the largest, if not the largest, image infringement cases in history" against Zillow, seeking over $1 billion in damages for the alleged unauthorized use of 46,979 copyrighted photographs.

But this is just the latest in a series of costly copyright battles:

• CoStar vs. Xceligent (2019): CoStar secured a $500 million judgment, though only $10.75 million was ultimately recovered from insurers after Xceligent's bankruptcy
• VHT vs. Zillow (2015-2022): After a six-year legal battle, Zillow was ordered to pay $1.9 million in damages for copyright infringement of approximately 2,700 photographs
• CoStar vs. CREXi (2020-ongoing): CoStar alleges that CREXi copied and cropped thousands of images, deliberately removing watermarks, and the case is moving to trial

The Hidden Costs Beyond Settlements

The true cost extends far beyond final judgments. CoStar CEO Andy Florance revealed that his company "spent more than double what it will receive on legal fees and its discovery process" in the Xceligent case, including international investigations and forensic analysis.

Consider the full financial impact: legal fees often exceeding settlement amounts, business disruption, reputational damage, and rising insurance premiums.

The Watermark Evidence Advantage

What made CoStar's cases particularly powerful? The complaint shows that Zillow unlawfully exploited tens of thousands of CoStar's watermarked photographs. Zillow's use of the images occurred over 250,000 times.

Visible watermarks, however, can be removed or cropped out by infringers. This is where invisible watermarking becomes game-changing.

The ROI Case for Invisible Watermarking

Current Industry Landscape:

• CoStar Group: $2.74 billion annual revenue (2024)
• Zillow Group: $2.24 billion annual revenue (2024)
• Compass: $5.63 billion annual revenue (2024)
• Redfin: $1.04 billion annual revenue (2024)

A comprehensive invisible watermarking solution typically costs a fraction of what companies spend on legal fees in a single major copyright dispute. If implementing invisible watermarking prevents just one major lawsuit, the cost savings could exceed 100:1. Consider that CoStar spent more than $21.5 million in legal fees on the Xceligent case alone.

Why Invisible Watermarking Changes Everything

Traditional visible watermarks can be removed, cropped, or obscured. Invisible watermarks, embedded imperceptibly within image data, provide:

• Irrefutable proof of ownership: cannot be removed without destroying image quality
• Chain of custody tracking: monitor exactly how and where images are used
• Automated monitoring: scale detection across millions of web properties
• Forensic evidence: court-admissible proof of infringement

Strategic Implementation

The most successful copyright enforcement strategies combine prevention (invisible watermarking), detection (automated monitoring), and prosecution (swift legal action with irrefutable evidence).

Since the 1990s, CoStar has filed at least 33 federal copyright-related lawsuits against competitors. "Court after court has ruled in CoStar's favor, issuing judgments and ordering permanent injunctions" largely because they could prove ownership and infringement.

Preparing for the Next Wave

CoStar's Andy Florance warned: "We can already see it happening again. We already have investigations into high-frequency, high-volume attempts to hack our servers and steal content from household companies that you would recognize."

As real estate intelligence becomes more valuable, copyright infringement will increase. Companies that wait until after infringement occurs will find themselves playing defense in expensive litigation.

The Strategic Imperative

With potential damages now reaching $1 billion in single cases, invisible watermarking has evolved from a nice-to-have technology to a business-critical asset protection tool. Legal teams that implement comprehensive watermarking strategies today position their organizations to deter infringement, detect violations automatically, prosecute cases with irrefutable evidence, and recover damages that reflect true business impact.

The question for real estate intelligence companies is not whether to invest in invisible watermarking, but whether they can afford not to. In an industry where a single lawsuit can exceed $1 billion, the ROI calculation has never been clearer.
