Portfolio overview

ZT Group Int'l, Inc. has been granted 66 US utility patents between 2017 and 2025, placing ZT Group Int'l, Inc. at rank #5,259 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a US Corporation, ZT Group Int'l, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, ZT sits between University Of Puerto Rico (66 patents, rank #5,255) and Buerkert Werke Gmbh (65 patents, rank #5,263) - the closest US assignees by grant volume. The composite Innovation Score of 62.5/100 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 56 grants, compared with 10 in the 2015–2019 window, a +460% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. ZT Group Int'l, Inc.'s 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZT Group Int'l, Inc. 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.
