Portfolio overview

Huaiyin Institute OF Technology has been granted 10 US utility patents between 2018 and 2023, placing Huaiyin Institute OF Technology at rank #26,454 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Huaiyin Institute OF Technology is one of the more focused assignees in the PatentsView dataset. By volume, Huaiyin sits between Hokuriku Electric Industry Co., Ltd. (10 patents, rank #26,450) and Hydac Accessories Gmbh (10 patents, rank #26,458) - the closest US assignees by grant volume. The composite Innovation Score of 45.0/100 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 8 grants, compared with 2 in the 2015–2019 window, a +300% 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. Huaiyin Institute OF Technology's 6.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Huaiyin Institute OF Technology against peers pursuing similar technology classes.
