Portfolio overview
Delta Electronics (Shanghai) Co., Ltd. has been granted 543 US utility patents between 2015 and 2025, placing Delta Electronics (Shanghai) Co., Ltd. at rank #838 across all assignees tracked by PlainPatent. This portfolio spans 67 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.6 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, Delta Electronics (Shanghai) Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 69.3/100 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 359 grants, compared with 184 in the 2015–2019 window — a +95% 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. Delta Electronics (Shanghai) Co., Ltd.'s 17.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 67 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Delta Electronics (Shanghai) Co., Ltd. against peers pursuing similar technology classes.
