Portfolio overview

Wangs Alliance Corporation has been granted 130 US utility patents between 2017 and 2025, placing Wangs Alliance Corporation at rank #2,939 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.0 claims per patent with primary concentration in F21V (FUNCTIONAL FEATURES OR DETAILS OF LIGHTING DEVICES OR SYSTEMS THEREOF; STRUCTURAL COMBINATIONS OF LIGHTING DEVICES WITH OTHER ARTICLES, NOT OTHERWISE PROVIDED FOR). As a US Corporation, Wangs Alliance Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Wangs sits between Self Electronics Co., Ltd. (130 patents, rank #2,935) and BASF Plant Science Company Gmbh (129 patents, rank #2,943) - the closest US assignees by grant volume. The composite Innovation Score of 62.9/100 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 122 grants, compared with 8 in the 2015–2019 window, a +1425% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. Wangs Alliance Corporation's 17.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wangs Alliance Corporation 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.
