The verdict
Z holds 10 US patents across 7 technology areas, rank #27,870 of 50,000 tracked assignees.
Z Intellectual Property Holding Company, Llc has been granted 10 US utility patents between 2021 and 2025, placing Z Intellectual Property Holding Company, Llc at rank #27,870 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.2 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a US Corporation, Z Intellectual Property Holding Company, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Z sits between Yongkang Saihan Blectronic Technology Co Ltd. (10 patents, rank #27,866) and Zenith Technologies, Llc (10 patents, rank #27,874) - the closest US assignees by grant volume. The composite Innovation Score of 49.8/100 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 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Z Intellectual Property Holding Company, Llc's 20.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Z Intellectual Property Holding Company, Llc against peers pursuing similar technology classes.

How to use this portfolio
Z's 10 grants land it in the top 14% 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.
