Portfolio overview
United TEST AND Assembly Center Ltd. has been granted 9 US utility patents between 2015 and 2019, placing United TEST AND Assembly Center Ltd. at rank #30,457 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, United TEST AND Assembly Center Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, United sits between Ultralogic 5G, Llc (9 patents, rank #30,453) and Universidad DE LA Republica (9 patents, rank #30,461) - the closest US assignees by grant volume. The composite Innovation Score of 26.9/100 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 0 grants, compared with 9 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. United TEST AND Assembly Center Ltd.'s 21.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark United TEST AND Assembly Center Ltd. against peers pursuing similar technology classes.
