Portfolio overview
EWI Holdings, Inc. has been granted 11 US utility patents between 2015 and 2021, placing EWI Holdings, Inc. at rank #24,260 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.2 claims per patent with primary concentration in H04M (TELEPHONIC COMMUNICATION). As a US Corporation, EWI Holdings, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, EWI sits between European Trailer Systems Gmbh (11 patents, rank #24,256) and Extron Company (11 patents, rank #24,264) - the closest US assignees by grant volume. The composite Innovation Score of 26.8/100 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. Between 2020 and 2025 the company received 4 grants, compared with 7 in the 2015–2019 window, a -43% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. EWI Holdings, Inc.'s 17.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EWI Holdings, Inc. against peers pursuing similar technology classes.
