#44,216
Across all tracked assignees
USPTO PatentsView assignee record - 6 granted patents across 4 technology areas, active 2015–2016. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY).
The verdict
Zerolemon holds 6 US patents across 4 technology areas, rank #44,216 of 50,000 tracked assignees.
Zerolemon Llc has been granted 6 US utility patents between 2015 and 2016, placing Zerolemon Llc at rank #44,216 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.2 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a US Corporation, Zerolemon Llc is one of the more focused assignees in the PatentsView dataset. By volume, Zerolemon sits between Zentech, Inc. (6 patents, rank #44,212) and Zhejiang Huangma Technology Co., Ltd. (6 patents, rank #44,220) - the closest US assignees by grant volume. The composite Innovation Score of 15.7/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Zerolemon Llc's 3.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zerolemon Llc against peers pursuing similar technology classes.

How to use this portfolio
Zerolemon's 6 grants land it in the top 97% 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.
