Portfolio overview

Energy Storage Materials Llc. has been granted 5 US utility patents between 2016 and 2019, placing Energy Storage Materials Llc. at rank #46,426 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 claims per patent with primary concentration in H01G (CAPACITORS; CAPACITORS, RECTIFIERS, DETECTORS, SWITCHING DEVICES, LIGHT-SENSITIVE OR TEMPERATURE-SENSITIVE DEVICES OF THE ELECTROLYTIC TYPE). As a Foreign Corporation, Energy Storage Materials Llc. is one of the more focused assignees in the PatentsView dataset. By volume, Energy sits between Energesis Pharmaceuticals, Inc. (5 patents, rank #46,422) and Enterin Laboratories, Inc. (5 patents, rank #46,430) - the closest US assignees by grant volume. The composite Innovation Score of 22.1/100 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 5 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 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. Energy Storage Materials Llc.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Energy Storage Materials Llc. against peers pursuing similar technology classes.
