Portfolio overview

Op-hygiene IP Gmbh has been granted 110 US utility patents between 2015 and 2025, placing Op-hygiene IP Gmbh at rank #3,380 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.1 claims per patent with primary concentration in A47K (SANITARY EQUIPMENT NOT OTHERWISE PROVIDED FOR ; TOILET ACCESSORIES). As a Foreign Corporation, Op-hygiene IP Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Op-hygiene sits between King's College London (110 patents, rank #3,376) and The ADT Security Corporation (110 patents, rank #3,384) - the closest US assignees by grant volume. The composite Innovation Score of 56.8/100 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. Between 2020 and 2025 the company received 70 grants, compared with 40 in the 2015–2019 window, a +75% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Op-hygiene IP Gmbh's 19.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Op-hygiene IP Gmbh 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.
