| description | The development status and trend of the patents related to sewage treatment technology in Dalian, China in the past decade may affect the future environmental protection industry development. The status quo of patent applications related to wastewater treatment technology was analyzed from the perspectives of application volume, disclosure volume, application organization, type composition of invention and utility model patent products and legal status. The results indicated that the total number of filed patents were 894, and the number of issued patents were 914 in recent ten years, showing an increasing trend for sewage treatment technology in Dalian, China. However, there were distinct differences between the application agencies of invention patents and utility model patents. Most of the invention patents came from universities, with 264 in the top five, and most of the utility model patents came from enterprises, with 134 in the top five. Among the product types, the highest number of patent applications was water, wastewater, or sludge treatment technology, a total of 761. At this point, the two patent directions had the same trend. In the state of law, although the number of applications and disclosures was 470, which was more than 416 actually authorized, it was not difficult to find that sewage treatment industry in Dalian, China was in an increasingly developing stage and the patents actually obtained had higher quality assurance. In conclusion, this essay from the perspective of patent application made a simple explanation the future development of sewage treatment industry and the problems existing in the practical application of sewage treatment technology. Finally, from the perspective of patent application, the paper analyzed the future development of sewage treatment industry and the problems existing in the practical application of sewage treatment technology. |
