The verdict
Lightbulb holds 7 US patents across 7 technology areas, rank #36,270 of 50,000 tracked assignees.
Lightbulb Innovation, Llc has been granted 7 US utility patents between 2020 and 2023, placing Lightbulb Innovation, Llc at rank #36,270 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in F25D (REFRIGERATORS; COLD ROOMS; ICE-BOXES; COOLING OR FREEZING APPARATUS NOT OTHERWISE PROVIDED FOR). As a US Corporation, Lightbulb Innovation, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Lightbulb sits between Lifewatch Technologies Ltd. (7 patents, rank #36,266) and Linde Engineering North America, Inc. (7 patents, rank #36,274) - the closest US assignees by grant volume. The composite Innovation Score of 33.4/100 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. Historical data spans 2020 through 2023, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Lightbulb Innovation, Llc's 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Lightbulb Innovation, Llc against peers pursuing similar technology classes.

How to use this portfolio
Lightbulb's 7 grants land it in the top 56% 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.
