Portfolio overview

CTERA Networks Ltd. has been granted 23 US utility patents between 2016 and 2025, placing CTERA Networks Ltd. at rank #12,868 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, CTERA Networks Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.2/100 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 13 grants, compared with 10 in the 2015–2019 window, a +30% 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. CTERA Networks Ltd.'s 18.0 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 CTERA Networks Ltd. against peers pursuing similar technology classes.
