Portfolio overview

Sungwoo Hitech Co., Ltd. has been granted 62 US utility patents between 2015 and 2025, placing Sungwoo Hitech Co., Ltd. at rank #5,549 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in B21D (WORKING OR PROCESSING OF SHEET METAL OR METAL TUBES, RODS OR PROFILES WITHOUT ESSENTIALLY REMOVING MATERIAL; PUNCHING METAL). As a Foreign Corporation, Sungwoo Hitech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sungwoo sits between Shanghaitech University (62 patents, rank #5,545) and Tron—translationale Onkologie An Der Universitätsmedizin Der Johannes Gutenberg-universität Mainz (62 patents, rank #5,553) - the closest US assignees by grant volume. The composite Innovation Score of 48.5/100 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 23 grants, compared with 39 in the 2015–2019 window, a -41% 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. Sungwoo Hitech Co., Ltd.'s 10.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sungwoo Hitech 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.
