Portfolio overview

Yotrio Group Co., Ltd. has been granted 26 US utility patents between 2015 and 2025, placing Yotrio Group Co., Ltd. at rank #11,884 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in A45B (WALKING STICKS ; UMBRELLAS; LADIES' OR LIKE FANS). As a Foreign Corporation, Yotrio Group Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Yotrio sits between Xuzhou Heavy Machinery Co., Ltd. (26 patents, rank #11,880) and Zoomlion Heavy Industry NA, Inc. (26 patents, rank #11,888) - the closest US assignees by grant volume. The composite Innovation Score of 53.4/100 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 15 grants, compared with 11 in the 2015–2019 window, a +36% 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. Yotrio Group Co., Ltd.'s 9.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yotrio Group Co., Ltd. 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.
