USPTO PatentsView assignee record - 6 granted patents across 5 technology areas, active 2018–2022. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS).
The verdict
Xiamen holds 6 US patents across 5 technology areas, rank #44,114 of 50,000 tracked assignees.
Xiamen Airpple Electronic Industry Co., Ltd. has been granted 6 US utility patents between 2018 and 2022, placing Xiamen Airpple Electronic Industry Co., Ltd. at rank #44,114 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.5 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, Xiamen Airpple Electronic Industry Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Xiamen sits between XGS Energy, Inc. (6 patents, rank #44,110) and Xiamen Mingho Brothers MFG Co., Ltd. (6 patents, rank #44,118) - the closest US assignees by grant volume. The composite Innovation Score of 18.4/100 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 2 grants, compared with 4 in the 2015–2019 window, a -50% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Xiamen Airpple Electronic Industry Co., Ltd.'s 2.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Xiamen Airpple Electronic Industry Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Xiamen's 6 grants land it in the top 95% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
