As a Foreign Corporation, CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITED is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 71.3/100 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 983 grants, compared with 46 in the 2015–2019 window — a +2037% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITED's 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITED against peers pursuing similar technology classes.
