Portfolio overview

Hongfujin Precision Electronics(tianjin)co., Ltd. has been granted 136 US utility patents between 2017 and 2022, placing Hongfujin Precision Electronics(tianjin)co., Ltd. at rank #2,820 across all assignees tracked by PlainPatent. This portfolio spans 63 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, Hongfujin Precision Electronics(tianjin)co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Hongfujin sits between Alphatec Spine, Inc. (136 patents, rank #2,816) and Jungheinrich Ag (136 patents, rank #2,824) - the closest US assignees by grant volume. The composite Innovation Score of 51.9/100 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 82 grants, compared with 54 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. Hongfujin Precision Electronics(tianjin)co., Ltd.'s 14.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 63 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hongfujin Precision Electronics(tianjin)co., Ltd. against peers pursuing similar technology classes.
