Portfolio overview

Suzhou Alton Electrical & Mechanical Industry Co., Ltd. has been granted 11 US utility patents between 2017 and 2025, placing Suzhou Alton Electrical & Mechanical Industry Co., Ltd. at rank #25,205 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in A61G (TRANSPORT, PERSONAL CONVEYANCES, OR ACCOMMODATION SPECIALLY ADAPTED FOR PATIENTS OR DISABLED PERSONS ; OPERATING TABLES OR CHAIRS; CHAIRS FOR DENTISTRY; FUNERAL DEVICES). As a Foreign Corporation, Suzhou Alton Electrical & Mechanical Industry Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Suzhou sits between Superflex, Ltd. (11 patents, rank #25,201) and Suzhou University OF Science AND Technology (11 patents, rank #25,209) - the closest US assignees by grant volume. The composite Innovation Score of 45.7/100 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 7 grants, compared with 4 in the 2015–2019 window, a +75% 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. Suzhou Alton Electrical & Mechanical Industry Co., Ltd.'s 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Suzhou Alton Electrical & Mechanical Industry Co., Ltd. against peers pursuing similar technology classes.
