Portfolio overview

W-scope Chungju Plant Co., Ltd. has been granted 6 US utility patents between 2021 and 2025, placing W-scope Chungju Plant Co., Ltd. at rank #43,980 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a Foreign Corporation, W-scope Chungju Plant Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, W-scope sits between Vortex Intellectual Property Holding Llc (6 patents, rank #43,976) and Wafer MEMS Co., Ltd. (6 patents, rank #43,984) - the closest US assignees by grant volume. The composite Innovation Score of 44.6/100 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. Historical data spans 2021 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. W-scope Chungju Plant Co., Ltd.'s 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark W-scope Chungju Plant 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.
