Portfolio overview

Grohe Ag has been granted 292 US utility patents between 2015 and 2025, placing Grohe Ag at rank #1,432 across all assignees tracked by PlainPatent. This portfolio spans 39 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.6 claims per patent with primary concentration in E03C (DOMESTIC PLUMBING INSTALLATIONS FOR FRESH WATER OR WASTE WATER ; SINKS). As a Foreign Corporation, Grohe Ag is one of the more focused assignees in the PatentsView dataset. By volume, Grohe sits between Silicon Storage Technology, Inc. (294 patents, rank #1,428) and Poulsen Roser A/s (291 patents, rank #1,436) - the closest US assignees by grant volume. The composite Innovation Score of 47.7/100 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 164 grants, compared with 128 in the 2015–2019 window, a +28% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Grohe Ag's 3.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 39 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Grohe Ag against peers pursuing similar technology classes.

How to use this portfolio

Grohe's 292 grants land it in the top 18% 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 - Grohe ranks #1,432 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in E03C - see who else leads that technology area. E03C 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.
