Listings giant Zillow finds itself at the center of one of the largest copyright disputes in history, serving as a stark reminder that intellectual property protections mean nothing without proper enforcement mechanisms.
Real estate analytics firm CoStar Group filed a federal lawsuit on July 30th, claiming Zillow deliberately violated copyright on more than 45,000 of its photographs. The company alleges Zillow used these images to attract property owners and managers to its platform while promoting advertising services.
CoStar estimates the infringement runs so deep that potential damages could hit $1 billion. This legal action comes alongside an existing Federal Trade Commission probe into Zillow’s arrangement with competitor Redfin, plus another lawsuit from brokerage firm Compass.
This is an indispensable paper, illustrating the unjust nature of today's system of intellectual property (IP) protection.

America’s IP Protection Framework Under Scrutiny
Should CoStar’s claims prove accurate, this situation would demonstrate just how vulnerable intellectual property rights remain, even within the United States. The U.S. Chamber of Commerce ranks America as having the world’s strongest IP protections, yet if such massive violations can occur here, the risks multiply dramatically in countries with weaker legal frameworks.
Americans already lose between $225 billion and $600 billion annually to intellectual property theft. While foreign actors, particularly those from China, account for much of this figure, domestic battles like the CoStar-Zillow dispute show the problem extends far beyond international bad actors.
Data from the National Intellectual Property Rights Coordination Center reveals IP theft has surged 21% in the past year. When these violations become routine practice, the damage spreads beyond individual creators to threaten the entire foundation of innovation-based economic growth.
Mixed Messages from Washington
Recent mixed signals from Washington have only made matters worse. The United States Trade Representative issued a blunt assessment in February 2025 regarding the Biden Administration’s support for the World Trade Organization’s TRIPS waiver, which exempts countries from enforcing certain intellectual property agreements.
By backing this waiver, the Biden Administration effectively endorsed the seizure of intellectual property rights from U.S.-based pharmaceutical companies by eligible WTO member nations. The stated goal was improving COVID-19 vaccine access in lower-income countries.
However, the USTR concluded that the waiver failed to increase vaccine access as promised. The agency warns that violating companies’ property rights will “negatively impact the development of new treatments and cures for the next pandemic by weakening the standard for intellectual property protections and furthering a false narrative about the role of intellectual property and access to medicines.”
When America fails to defend its own IP standards on the global stage, it gives foreign governments a green light to continue treating American innovation as targets for state-sponsored theft. This approach also sends a troubling message to U.S. companies: if Washington treats IP protections as negotiable, why shouldn’t they follow suit?
The stakes couldn’t be higher. Intellectual property forms the foundation of American dominance in technology, medicine, entertainment, and artificial intelligence. Weakening these protections reduces innovation incentives, slows the development of new medical treatments, and eliminates jobs in the industries driving economic expansion. While CoStar has the financial resources to challenge a well-funded alleged violator, countless smaller companies and individual creators lack the means to defend their rights.
The federal government has made meaningful progress over the past six months by clarifying that IP protections shouldn’t serve as negotiating tools. This principle must now guide both trade policy and domestic enforcement efforts.
Washington needs to hold foreign competitors accountable while ensuring America’s legal system delivers quick, substantial consequences for domestic IP theft. Companies cannot be permitted to build market position by exploiting others’ investments without permission.
The Zillow lawsuit represents more than just another corporate legal battle. It underscores the critical importance of consistently enforcing the intellectual property rights that power America’s technology-driven economy. Failing this test means costs won’t just appear in court settlements, but in the gradual erosion of America’s most significant competitive edge.
Broader Economic Implications
This massive intellectual property dispute highlights growing concerns about enforcement mechanisms across innovation-driven sectors. The outcome could signal whether current legal frameworks provide adequate protection for companies investing heavily in proprietary assets and technologies.
