Portfolio overview

H2plus Llc has been granted 8 US utility patents between 2024 and 2025, placing H2plus Llc at rank #31,849 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a US Corporation, H2plus Llc is one of the more focused assignees in the PatentsView dataset. By volume, H2plus sits between Guangzhou Yu Junrui Trading Co., Ltd (8 patents, rank #31,845) and Hachiman-kasei Co., Ltd. (8 patents, rank #31,853) - the closest US assignees by grant volume. The composite Innovation Score of 50.6/100 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 2024 through 2025, with 8 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. H2plus Llc's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark H2plus Llc against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
