Portfolio overview

Hangzhou Qingqi Science AND Technology Co., Ltd. has been granted 6 US utility patents between 2021 and 2023, placing Hangzhou Qingqi Science AND Technology Co., Ltd. at rank #40,600 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in H04W (WIRELESS COMMUNICATION NETWORKS). As a Foreign Corporation, Hangzhou Qingqi Science AND Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hangzhou sits between Hangzhou Jingcheng Sanhe Timer Industry Co., Ltd. (6 patents, rank #40,596) and Hanil E-HWA Co., Ltd. (6 patents, rank #40,604) - the closest US assignees by grant volume. The composite Innovation Score of 37.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2021 through 2023, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Hangzhou Qingqi Science AND Technology Co., Ltd.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hangzhou Qingqi Science AND Technology Co., Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
