When The New York Times needed to prove which company built China’s leaked surveillance platform for foreigners, the company itself didn’t confirm anything — neither did the police bureau running it. Patent disclosure did the talking instead.
The Times traced the platform — an unsecured police dashboard in Zhangjiakou that held records on more than 700 foreigners and nearly 12,000 entries total, including passport data, hospital visits, and high-speed rail seat numbers — to a Beijing company called Origin Dynamic, which sells robotics and surveillance equipment to police through public tenders. Origin Dynamic didn’t respond to requests for comment. But in 2023, the company had filed a patent for something it described as an “information interface for non-Chinese citizens,” and reporters found its design and functions nearly identical to the leaked platform. Worth noting: the dashboard was reportedly taken offline in May, and it’s unclear whether other Chinese cities run comparable systems — most of what’s public here still flows through one researcher and one news outlet.
This is a research technique that shows up far beyond this story: patent filings are one of the few windows into companies that don’t have to explain themselves any other way. Private companies skip earnings calls, and companies serving governments in surveillance, defense, or security often skip public marketing entirely. But a patent application is filed with a government office, published on a public register, and has to describe — in real technical detail — what the thing actually does. Investors and researchers use the same trick on defense contractors and cybersecurity vendors: if a company won’t tell you what it builds, its patent filings sometimes will.
It’s the same instinct behind tracing what a company’s technology can actually do through documentation rather than press releases — public filings often say more than any spokesperson will.
My take: Companies that won’t talk still leave paperwork.
Not advice. Just how I see it.
