Portfolio overview

King Technology, Inc. has been granted 66 US utility patents between 2015 and 2025, placing King Technology, Inc. at rank #5,221 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a US Corporation, King Technology, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, King sits between Kabushiki Kaisha Yakult Honsha (66 patents, rank #5,217) and Landis+gyr Ag (66 patents, rank #5,225) - the closest US assignees by grant volume. The composite Innovation Score of 40.2/100 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 38 grants, compared with 28 in the 2015–2019 window, a +36% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. King Technology, Inc.'s 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark King Technology, Inc. against peers pursuing similar technology classes.

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.
