Portfolio overview

Kyung Chang Industrial Co., Ltd. has been granted 59 US utility patents between 2015 and 2025, placing Kyung Chang Industrial Co., Ltd. at rank #5,775 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in G05G (CONTROL DEVICES OR SYSTEMS INSOFAR AS CHARACTERISED BY MECHANICAL FEATURES ONLY). As a Foreign Corporation, Kyung Chang Industrial Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kyung sits between Instrumentation Laboratory (59 patents, rank #5,771) and Microfabrica Inc. (59 patents, rank #5,779) - the closest US assignees by grant volume. The composite Innovation Score of 46.9/100 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 24 in the 2015–2019 window, a +46% 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. Kyung Chang Industrial Co., Ltd.'s 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kyung Chang Industrial 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.
