Portfolio overview
SILICONWARE PRECISION INDUSTRIES CO., LTD. has been granted 379 US utility patents between 2015 and 2025, placing SILICONWARE PRECISION INDUSTRIES CO., LTD. at rank #1,120 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, SILICONWARE PRECISION INDUSTRIES CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 54.1/100 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 169 grants, compared with 210 in the 2015–2019 window — a -20% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. SILICONWARE PRECISION INDUSTRIES CO., LTD.'s 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 SILICONWARE PRECISION INDUSTRIES CO., LTD. against peers pursuing similar technology classes.
