Portfolio overview

Aurora Office Equipment Co., Ltd. Shanghai has been granted 23 US utility patents between 2015 and 2023, placing Aurora Office Equipment Co., Ltd. Shanghai at rank #12,821 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in B02C (CRUSHING, PULVERISING, OR DISINTEGRATING IN GENERAL; MILLING GRAIN). As a Foreign Corporation, Aurora Office Equipment Co., Ltd. Shanghai is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 29.7/100 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 14 grants, compared with 9 in the 2015–2019 window — a +56% 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. Aurora Office Equipment Co., Ltd. Shanghai's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Aurora Office Equipment Co., Ltd. Shanghai against peers pursuing similar technology classes.
