As a Foreign Corporation, CONTEMPORARY AMPEREX TECHNOLOGY (HONG KONG) LIMITED is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 74.8/100 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. Historical data spans 2024 through 2025, with 387 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 (HONG KONG) LIMITED's 15.3 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 (HONG KONG) LIMITED against peers pursuing similar technology classes.
