Portfolio overview
Nanjing Chervon Industry Co., Ltd. has been granted 283 US utility patents between 2018 and 2025, placing Nanjing Chervon Industry Co., Ltd. at rank #1,470 across all assignees tracked by PlainPatent. This portfolio spans 71 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in B25F (COMBINATION OR MULTI-PURPOSE TOOLS NOT OTHERWISE PROVIDED FOR; DETAILS OR COMPONENTS OF PORTABLE POWER-DRIVEN TOOLS NOT PARTICULARLY RELATED TO THE OPERATIONS PERFORMED AND NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Nanjing Chervon Industry Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 66.0/100 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 265 grants, compared with 18 in the 2015–2019 window — a +1372% 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. Nanjing Chervon Industry Co., Ltd.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 71 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nanjing Chervon Industry Co., Ltd. against peers pursuing similar technology classes.
