Portfolio overview

PLK Technologies Co., Ltd. has been granted 10 US utility patents between 2015 and 2019, placing PLK Technologies Co., Ltd. at rank #27,093 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.5 claims per patent with primary concentration in G06V (IMAGE OR VIDEO RECOGNITION OR UNDERSTANDING). As a Foreign Corporation, PLK Technologies Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, PLK sits between Play'n GO Marks Ltd (10 patents, rank #27,089) and POLY DOME Ontario Inc. (10 patents, rank #27,097) - the closest US assignees by grant volume. The composite Innovation Score of 29.0/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. PLK Technologies Co., Ltd.'s 12.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark PLK Technologies 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.
