SII Semiconductor Corporation

SII Semiconductor Corporation has been granted 164 US utility patents between 2016 and 2019, placing SII Semiconductor Corporation at rank #2,384 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, SII Semiconductor Corporation is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.4/100 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 0 grants, compared with 164 in the 2015–2019 window — a -100% 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. SII Semiconductor Corporation's 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SII Semiconductor Corporation against peers pursuing similar technology classes.
