Portfolio overview

Vatech EWOO Holdings Co., Ltd. has been granted 85 US utility patents between 2016 and 2025, placing Vatech EWOO Holdings Co., Ltd. at rank #4,230 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Vatech EWOO Holdings Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Vatech sits between Thomson Reuters Enterprise Centre Gmbh (85 patents, rank #4,226) and Cybex Gmbh (84 patents, rank #4,234) - the closest US assignees by grant volume. The composite Innovation Score of 40.3/100 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 35 grants, compared with 50 in the 2015–2019 window, a -30% 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. Vatech EWOO Holdings Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Vatech EWOO Holdings Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
