Portfolio overview
Delta Electronics, Inc. has been granted 1,815 US utility patents between 2015 and 2025, placing Delta Electronics, Inc. at rank #224 across all assignees tracked by PlainPatent. This portfolio spans 191 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 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, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 66.9/100 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 1,060 grants, compared with 755 in the 2015–2019 window — a +40% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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, Inc.'s 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Delta Electronics, Inc. against peers pursuing similar technology classes.
