Portfolio overview

Dong-a Socio Holdings Co., Ltd. has been granted 6 US utility patents between 2017 and 2025, placing Dong-a Socio Holdings Co., Ltd. at rank #39,788 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, Dong-a Socio Holdings Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Dong-a sits between DMR International, Inc. (6 patents, rank #39,784) and Dongguan Hongyi Wiper Co., Ltd. (6 patents, rank #39,792) - the closest US assignees by grant volume. The composite Innovation Score of 20.9/100 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 4 grants, compared with 2 in the 2015–2019 window, a +100% 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. Dong-a Socio Holdings Co., Ltd.'s 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dong-a Socio Holdings 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.
