Portfolio overview

HBL Corporation has been granted 7 US utility patents between 2016 and 2024, placing HBL Corporation at rank #35,622 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a Foreign Corporation, HBL Corporation is one of the more focused assignees in the PatentsView dataset. By volume, HBL sits between Harumoto Technology (shen Zhen) Co., Ltd. (7 patents, rank #35,618) and Hefei JEE Power Systems Co., Ltd. (7 patents, rank #35,626) - the closest US assignees by grant volume. The composite Innovation Score of 45.6/100 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. Between 2020 and 2025 the company received 4 grants, compared with 3 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. HBL Corporation's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HBL Corporation against peers pursuing similar technology classes.

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.
