YITU Technology Patents

Patent portfolio assigned to YITU Technology (verified via public assignee records). Estimated patent count: 1000. Chinese AI / computer-vision company (legal entity Shanghai Yitu Network Technology / 上海依图网络科技有限公司). Customer West China Hospital confirmed on YITU's own case-study page. Competitors are fellow 'AI Four Dragons' (SenseTime, Megvii, CloudWalk) grouped together in the fetched article. Google Patents shows a large footprint for the verified Chinese assignee (image-processing, medical-imaging patents); count is an order-of-magnitude estimate. Note: bare '依图科技' string also matches an unrelated Hainan company, so the verified network-tech entity was used.
