Portfolio overview
Silicon Precision Industries Co., Ltd. has been granted 6 US utility patents between 2018 and 2023, placing Silicon Precision Industries Co., Ltd. at rank #43,246 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Silicon Precision Industries Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Silicon sits between Sightglass Vision, Inc. (6 patents, rank #43,242) and Simplex Manufacturing Co. (6 patents, rank #43,250) - the closest US assignees by grant volume. The composite Innovation Score of 23.3/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% 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. Silicon Precision Industries Co., Ltd.'s 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silicon Precision Industries Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Silicon's 6 grants land it in the top 88% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Silicon ranks #43,246 of 50,000. Top 50 holders
- Most of this portfolio concentrates in H01L - see who else leads that technology area. H01L leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
