Portfolio overview

Kyungdong Navien Co., Ltd. has been granted 142 US utility patents between 2015 and 2025, placing Kyungdong Navien Co., Ltd. at rank #2,726 across all assignees tracked by PlainPatent. This portfolio spans 44 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.4 claims per patent with primary concentration in F24H (FLUID HEATERS, e.g. WATER OR AIR HEATERS, HAVING HEAT-GENERATING MEANS, e.g. HEAT PUMPS, IN GENERAL). As a Foreign Corporation, Kyungdong Navien Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kyungdong sits between Fondazione Istituto Italiano DI Tecnologia (142 patents, rank #2,722) and Outdoor Wireless Networks Llc (142 patents, rank #2,730) - the closest US assignees by grant volume. The composite Innovation Score of 56.4/100 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 99 grants, compared with 43 in the 2015–2019 window, a +130% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Kyungdong Navien 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 44 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kyungdong Navien Co., Ltd. against peers pursuing similar technology classes.
