Court Rules that Crawling Naver’s Real-Estate Database Is Illegal
Court Rules that Crawling Naver’s Real-Estate Database Is Illegal
As legal
disputes continue over the copyrightability of databases accumulated by
platform companies, a Korean court has ruled that unauthorized crawling and use
of Naver’s real-estate database is unlawful. The ruling confirms that even if a
platform did not originally create the underlying data, copyright protection
may still apply when the platform has invested significant labor and resources
in organizing, verifying, and processing the data. With courts increasingly
recognizing database copyright strictly, disputes over data crawling between
large platforms and startups are expected to increase.
Patent
Court: “Naver Made Substantial Human and Financial Investments”
According to
the legal community on the 4th, the 24th panel of the Patent Court (Presiding
Judge Woo Sung-yeop) ruled last month, on the 24th, in favor of Naver and Naver
Financial in part in their damages lawsuit against Darwin Property. The court
held that Darwin Property must not reproduce or transmit Naver’s real-estate
database and ordered it to pay 80 million won in damages. This amount is 10
million won higher than the 70 million won awarded at first instance on
September 1, 2024. The court also ordered Darwin Property to delete Naver
real-estate data stored on its servers, including 24 categories of information
such as apartment prices, floor area, building number, and floor level.
Darwin
Property had crawled Naver’s real-estate listings in February 2021 and posted
them on its own platform, Darwin Brokerage. After Naver demanded that Darwin
stop collecting and using the data without authorization, Darwin switched to an
“out-link” model, placing icons next to listings that, when clicked, opened the
corresponding Naver real-estate page in a new window. Naver nevertheless filed
suit, arguing that this still constituted unauthorized use of its data.
The court
held that Naver qualified as the database producer and therefore owned the
copyright. It explained that Naver had made substantial human and financial
investments, including spending approximately 1 billion won to build and
maintain a verification system that filters out false real-estate listings. The
court further reasoned that even though Naver obtained listing data from
real-estate agencies, it edited and arranged that data in a way tailored to
Naver’s system, meaning Naver could not be regarded as a mere user of the
information.
Different
Outcomes Depending on the Nature of Crawled Data
Legal
experts expect this appellate ruling to lead to more disputes over data
crawling. Attorney Kwak Jae-woo of Lee & Ko, who represented Naver, said
that courts have recently been more inclined to recognize database property
rights. He added that although more Supreme Court precedents are needed, the
fact that rights can be recognized whenever data is edited and processed with
effort means that disputes are likely to increase.
There is
also concern in the industry that startups offering services based on crawling
the databases of large platforms like Naver will face significant litigation
risks.
Courts have
recently tended to assess the qualitative nature of crawled data more strictly
when determining illegality. Outcomes differ depending on whether the data is
merely publicly available information or has been processed and curated.
In Yanolja
v. YeogiEottae, in which the founder of Yeogi Eottae crawled data from
Yanolja’s servers, the Supreme Court acquitted the defendant in 2022. The
Second Criminal Division of the Supreme Court held that the crawled data
consisted mainly of publicly available information such as hotel names and
addresses, and therefore did not constitute violations of the Information and
Communications Network Act or the Copyright Act.
In JobKorea
v. Saramin, Saramin copied JobKorea’s recruitment listings by crawling
JobKorea’s database and reposted those listings on its own job-search platform.
The Supreme Court held that JobKorea qualified as the producer of a protected
database because it had made substantial investment in collecting, verifying,
and organizing the recruitment information. As a result, Saramin’s large-scale
extraction and reuse of that data was found to infringe JobKorea’s database
copyright.
