Portfolio overview

Eagle Industry Co., Ltd. has been granted 370 US utility patents between 2015 and 2025, placing Eagle Industry Co., Ltd. at rank #1,143 across all assignees tracked by PlainPatent. This portfolio spans 58 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in F16J (PISTONS ; CYLINDERS; SEALINGS). As a Foreign Corporation, Eagle Industry Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Eagle sits between The Curators Of The University Of Missouri (371 patents, rank #1,139) and AAC Optics Solutions Pte. Ltd. (369 patents, rank #1,147) - the closest US assignees by grant volume. The composite Innovation Score of 60.9/100 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 223 grants, compared with 147 in the 2015–2019 window, a +52% 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. Eagle Industry Co., Ltd.'s 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 58 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Eagle Industry 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.
