Portfolio overview

Beijing Naura Microelectronics Equipment Co., Ltd. has been granted 113 US utility patents between 2018 and 2025, placing Beijing Naura Microelectronics Equipment Co., Ltd. at rank #3,297 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Beijing Naura Microelectronics Equipment Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Beijing sits between Unity Technologies SF (114 patents, rank #3,293) and DANA Belgium N.v. (113 patents, rank #3,301) - the closest US assignees by grant volume. The composite Innovation Score of 52.2/100 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 96 grants, compared with 17 in the 2015–2019 window, a +465% 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. Beijing Naura Microelectronics Equipment Co., Ltd.'s 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Beijing Naura Microelectronics Equipment Co., Ltd. against peers pursuing similar technology classes.
