Portfolio overview
Amtek Semiconductor Co., Ltd. has been granted 5 US utility patents between 2015 and 2017, placing Amtek Semiconductor Co., Ltd. at rank #44,868 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Amtek Semiconductor Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Amtek sits between Amity Technology, Llc (5 patents, rank #44,864) and Anaeropharma Science, Inc. (5 patents, rank #44,872) - the closest US assignees by grant volume. The composite Innovation Score of 21.7/100 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 5 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. Amtek Semiconductor Co., Ltd.'s 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Amtek Semiconductor Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Amtek's 5 grants land it in the top 91% 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 - Amtek ranks #44,868 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.
