Portfolio overview

Nanjing Easthouse Electrical Co., Ltd. has been granted 33 US utility patents between 2017 and 2025, placing Nanjing Easthouse Electrical Co., Ltd. at rank #9,568 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in G07C (TIME OR ATTENDANCE REGISTERS; REGISTERING OR INDICATING THE WORKING OF MACHINES; GENERATING RANDOM NUMBERS; VOTING OR LOTTERY APPARATUS; ARRANGEMENTS, SYSTEMS OR APPARATUS FOR CHECKING NOT PROVIDED FO). As a Foreign Corporation, Nanjing Easthouse Electrical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.6/100 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. Between 2020 and 2025 the company received 28 grants, compared with 5 in the 2015–2019 window, a +460% 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. Nanjing Easthouse Electrical Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanjing Easthouse Electrical Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Nanjing's 33 grants land it in the top 33% 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 - Nanjing ranks #9,568 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G07C - see who else leads that technology area. G07C 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.
