Portfolio overview

ZFX Gmbh has been granted 8 US utility patents between 2017 and 2023, placing ZFX Gmbh at rank #33,959 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.0 claims per patent with primary concentration in A61C (DENTISTRY; APPARATUS OR METHODS FOR ORAL OR DENTAL HYGIENE). As a Foreign Corporation, ZFX Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, ZFX sits between ZEKU Technology (shanghai) Corp., Ltd. (8 patents, rank #33,955) and Zhejiang Jingyi NEW Material Technology Co. Ltd (8 patents, rank #33,963) - the closest US assignees by grant volume. The composite Innovation Score of 29.4/100 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 3 grants, compared with 5 in the 2015–2019 window, a -40% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ZFX Gmbh's 18.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZFX Gmbh against peers pursuing similar technology classes.

How to use this portfolio

ZFX's 8 grants land it in the top 69% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - ZFX ranks #33,959 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A61C - see who else leads that technology area. A61C leaders
  • 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.
