The verdict
ZIH holds 149 US patents across 42 technology areas, rank #2,620 of 50,000 tracked assignees.
ZIH Corp. has been granted 149 US utility patents between 2015 and 2020, placing ZIH Corp. at rank #2,620 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in B41J (TYPEWRITERS; SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS). As a US Corporation, ZIH Corp. is one of the more focused assignees in the PatentsView dataset. By volume, ZIH sits between Teradyne, Inc. (149 patents, rank #2,616) and Casale Sa (148 patents, rank #2,624) - the closest US assignees by grant volume. The composite Innovation Score of 51.2/100 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 1 grants, compared with 148 in the 2015–2019 window, a -99% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ZIH Corp.'s 18.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZIH Corp. against peers pursuing similar technology classes.

How to use this portfolio
ZIH's 149 grants land it in the top 12% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
