China’s Humanoid Robot Patent Lead Widens, but the Data Has Limits

China’s share of humanoid-robot patent activity across the five major patent offices rose to 60.8% in the first half of 2026. The United States accounted for 21.8% and South Korea 4.6%. In robot foundation models, a related area focused on the software and learning systems behind robots, China’s reported share was 66.3%, compared with South Korea’s 8.8%.217

Those figures point to a widening gap in reported patent activity, not a definitive ranking of which country builds the best robots. The latest counts are provisional, and the available evidence on industrial-robot installations does not provide a comparable 2025 country-by-country picture.

China’s lead in the reported patent figures

Across the IP5 patent offices, China’s humanoid-robot share increased from 51.8% in 2024 to 60.8% in the first half of 2026. South Korea’s share fell from 6.3% to 4.6% over the same reported period; the U.S. share declined from 27.3% to 21.8%.2

Application counts show the difference in scale. China filed 1,584 humanoid-robot applications in the first half of 2026, compared with 113 from the United States and 35 from South Korea. In 2025, the reported totals were 2,573 for China, 640 for the United States and 97 for South Korea.217

Robot foundation model figures show a similar imbalance, but the provided reporting gives specific country shares only for China and South Korea: 66.3% and 8.8%, respectively, in the first half of 2026. It does not establish a comparable U.S. share.17

Why the numbers need qualification

Recent patent counts are provisional: the reporting notes that applications can take 18 months to become public, so recently filed applications may not yet appear in the data.16 The figures are therefore a snapshot, not a complete final count of first-half 2026 activity.

Patent share also measures the volume of activity in the reported dataset, not the technical value of each patent, whether an invention works reliably, or whether it is used in commercial products. The figures support a claim about scale; on their own, they cannot establish that one country has the most capable robots.

Supply chains and shipments add context

Patent activity is only one part of China’s position. Reporting describes Chinese capabilities across the humanoid-robot supply chain, from chips and components to complete machines.10 Chinese vendors also accounted for more than 97% of global humanoid-robot shipments in the first half of 2026, when worldwide shipments were reported at about 19,100 units.1

That shipment lead is evidence of manufacturing and sales scale, not proof that humanoids are already widely doing factory work. A review of major vendors describes paid commercial deployment as concentrated in logistics and warehousing; in manufacturing, it reports production-line verification at a single station, while home use remains at an early stage.3

South Korea faces a different supply-chain challenge. One report estimates that domestic manufacturers make about 40% of the core parts used in the country’s robots. It also says South Korea sourced 88.8% of robot-motor permanent magnets from China in 2025 and relies on Japan for many precision reducers and controllers.4 That dependence is relevant to the competition, but it does not by itself explain the patent gap.

What industrial-robot installation data says—and doesn’t

Industrial robots are a separate category from humanoid robots. The best-defined installation benchmark in the provided sources is for 2024: China recorded 295,000 new industrial-robot installations, about 54% of the global total, and had an operational stock of approximately 2.03 million robots in factories.15

That is useful context for the scale of China’s broader automation market, but it is not a 2025 installation total and should not be presented as one. The available sources do not provide a comparable, verified set of 2025 industrial-robot installation figures for China, the United States and South Korea.

The stakes for South Korea

The figures raise a strategic question for South Korea: whether it can build stronger capabilities in the components and software that underpin robots, alongside its efforts to develop complete machines. The patent data came from information obtained by lawmaker Lee Jeong-heon’s office, while reporting also describes South Korea’s component-sourcing exposure.24

The sources provided here do not establish the details of Hyundai’s response or support a specific quotation of Lee’s warning. Those points should not be inferred from the patent and supply-chain figures alone. What the evidence does show is a substantial gap in reported patent activity, a large Chinese share of recent humanoid shipments, and continued questions about how quickly humanoid robots will move from limited deployments into wider industrial use.12317
