USPTO PatentsView assignee record - 5 granted patents across 2 technology areas, active 2021–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47C (CHAIRS; SOFAS; BEDS).
The verdict
Dongguan holds 5 US patents across 2 technology areas, rank #46,137 of 50,000 tracked assignees.
Dongguan Weihong Smart HOME Technology Co., Ltd. has been granted 5 US utility patents between 2021 and 2024, placing Dongguan Weihong Smart HOME Technology Co., Ltd. at rank #46,137 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in A47C (CHAIRS; SOFAS; BEDS). As a Foreign Corporation, Dongguan Weihong Smart HOME Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Dongguan sits between Dongguan Paifan Electronic Technology Co., Ltd. (5 patents, rank #46,133) and Dongguk University Gyeongju Campus Industry-academy Cooperation Foundation (5 patents, rank #46,141) - the closest US assignees by grant volume. The composite Innovation Score of 17.5/100 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. Historical data spans 2021 through 2024, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Dongguan Weihong Smart HOME Technology Co., Ltd.'s 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dongguan Weihong Smart HOME Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Dongguan's 5 grants land it in the top 96% 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.
