Portfolio overview

Shenzhen First Union Technology Co., Ltd. has been granted 175 US utility patents between 2015 and 2025, placing Shenzhen First Union Technology Co., Ltd. at rank #2,246 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES). As a Foreign Corporation, Shenzhen First Union Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between LNW Gaming, Inc. (175 patents, rank #2,242) and Edgewell Personal Care Brands, Llc (174 patents, rank #2,250) - the closest US assignees by grant volume. The composite Innovation Score of 50.9/100 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 109 grants, compared with 66 in the 2015–2019 window, a +65% 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. Shenzhen First Union Technology Co., Ltd.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen First Union Technology 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.
