NLDP (Natural Language Data Processing) technology is a field of AI (Artificial Intelligence) and is widely used in smart technology applications such as smart customer service, smart retailing, chatbots, educational robots and domestic robots. By adopting NLDP technology, a computer is able to communicate and interact with humans more naturally and intuitively. More and more leading international vendors are rolling out various kinds of smart devices supporting English and Japanese NLDP technology. In contrast, there are relatively few Chinese NLDP-supported devices in the market. This report provides an overview of Chinese NLDP patent trends analysis by country and field; examines key technologies and major patent assignees. Also included are the insights about potential market opportunities and challenges of NLDP patent deployment for newcomers.
