Portfolio overview

Kctech Co., Ltd. has been granted 35 US utility patents between 2018 and 2025, placing Kctech Co., Ltd. at rank #9,062 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Kctech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kctech sits between JCM American Corporation (35 patents, rank #9,058) and Koch-glitsch, Lp (35 patents, rank #9,066) - the closest US assignees by grant volume. The composite Innovation Score of 57.6/100 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 27 grants, compared with 8 in the 2015–2019 window, a +238% 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. Kctech Co., Ltd.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kctech 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.
