Portfolio overview

Corplex Plastics UK Ltd. has been granted 6 US utility patents between 2020 and 2022, placing Corplex Plastics UK Ltd. at rank #39,668 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in B67D (DISPENSING, DELIVERING OR TRANSFERRING LIQUIDS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Corplex Plastics UK Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Corplex sits between Core Thermal, Inc. (6 patents, rank #39,664) and Count & Crush Systems, Llc (6 patents, rank #39,672) - the closest US assignees by grant volume. The composite Innovation Score of 25.1/100 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 2020 through 2022, 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. Corplex Plastics UK Ltd.'s 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Corplex Plastics UK 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.
