Portfolio overview

Zhejiang Ikahe Sanitary WARE Co., Ltd. has been granted 9 US utility patents between 2020 and 2024, placing Zhejiang Ikahe Sanitary WARE Co., Ltd. at rank #30,637 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.1 claims per patent with primary concentration in E03D (WATER-CLOSETS OR URINALS WITH FLUSHING DEVICES; FLUSHING VALVES THEREFOR). As a Foreign Corporation, Zhejiang Ikahe Sanitary WARE Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Zhejiang sits between Zhejiang Academy OF Agricultural Sciences (9 patents, rank #30,633) and Zhejiang Rongsheng Tools Co., Ltd (9 patents, rank #30,641) - the closest US assignees by grant volume. The composite Innovation Score of 17.6/100 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 2020 through 2024, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Zhejiang Ikahe Sanitary WARE Co., Ltd.'s 2.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zhejiang Ikahe Sanitary WARE Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Zhejiang's 9 grants land it in the top 96% 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 - Zhejiang ranks #30,637 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in E03D - see who else leads that technology area. E03D 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.
