The verdict
Lumen holds 5 US patents across 5 technology areas, rank #48,489 of 50,000 tracked assignees.
Lumen Labs (hk) Limited has been granted 5 US utility patents between 2020 and 2021, placing Lumen Labs (hk) Limited at rank #48,489 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.6 claims per patent with primary concentration in A42B (HATS; HEAD COVERINGS). As a Foreign Corporation, Lumen Labs (hk) Limited is one of the more focused assignees in the PatentsView dataset. By volume, Lumen sits between Ludlum Measurements, Inc. (5 patents, rank #48,485) and Lumien Enterprise, Inc. (5 patents, rank #48,493) - the closest US assignees by grant volume. The composite Innovation Score of 16.9/100 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. Historical data spans 2020 through 2021, 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. Lumen Labs (hk) Limited's 4.6 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 Lumen Labs (hk) Limited against peers pursuing similar technology classes.

How to use this portfolio
Lumen'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.
