Portfolio overview

K-tronics (suzhou) Technology Co., Ltd. has been granted 120 US utility patents between 2016 and 2025, placing K-tronics (suzhou) Technology Co., Ltd. at rank #3,135 across all assignees tracked by PlainPatent. This portfolio spans 55 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in G02F (OPTICAL DEVICES OR ARRANGEMENTS FOR THE CONTROL OF LIGHT BY MODIFICATION OF THE OPTICAL PROPERTIES OF THE MEDIA OF THE ELEMENTS INVOLVED THEREIN; NON-LINEAR OPTICS; FREQUENCY-CHANGING OF LIGHT; OPTICA). As a Foreign Corporation, K-tronics (suzhou) Technology Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, K-tronics sits between GRG Banking Equipment Co., Ltd. (120 patents, rank #3,131) and North Inc. (120 patents, rank #3,139) - the closest US assignees by grant volume. The composite Innovation Score of 58.7/100 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 85 grants, compared with 35 in the 2015–2019 window, a +143% 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. K-tronics (suzhou) Technology Co., Ltd.'s 14.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 55 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark K-tronics (suzhou) Technology Co., Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
