Portfolio overview

Noritz Corporation has been granted 184 US utility patents between 2015 and 2025, placing Noritz Corporation at rank #2,145 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in F24H (FLUID HEATERS, e.g. WATER OR AIR HEATERS, HAVING HEAT-GENERATING MEANS, e.g. HEAT PUMPS, IN GENERAL). As a Foreign Corporation, Noritz Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Noritz sits between Foundation OF Soongsil University-industry Cooperation (184 patents, rank #2,141) and Avalanche Technology, Inc. (183 patents, rank #2,149) - the closest US assignees by grant volume. The composite Innovation Score of 50.0/100 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 100 grants, compared with 84 in the 2015–2019 window, a +19% 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. Noritz Corporation's 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Noritz Corporation against peers pursuing similar technology classes.

How to use this portfolio

Noritz's 184 grants land it in the top 14% 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 - Noritz ranks #2,145 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F24H - see who else leads that technology area. F24H 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.
