Portfolio overview

QING DING PRECISION ELECTRONICS (HUAIAN) CO., LTD has been granted 77 US utility patents between 2019 and 2025, placing QING DING PRECISION ELECTRONICS (HUAIAN) CO., LTD at rank #4,579 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.0 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, QING DING PRECISION ELECTRONICS (HUAIAN) CO., LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 60.7/100 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. Between 2020 and 2025 the company received 76 grants, compared with 1 in the 2015–2019 window — a +7500% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. QING DING PRECISION ELECTRONICS (HUAIAN) CO., LTD's 11.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark QING DING PRECISION ELECTRONICS (HUAIAN) CO., LTD against peers pursuing similar technology classes.
