Portfolio overview

Northstar Battery Company, Llc has been granted 11 US utility patents between 2018 and 2022, placing Northstar Battery Company, Llc at rank #24,866 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Northstar Battery Company, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Northstar sits between Nippon Yusen Kabushiki Kaisha (11 patents, rank #24,862) and NSV Group FZCO (11 patents, rank #24,870) - the closest US assignees by grant volume. The composite Innovation Score of 34.4/100 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. Between 2020 and 2025 the company received 10 grants, compared with 1 in the 2015–2019 window, a +900% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Northstar Battery Company, Llc's 18.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Northstar Battery Company, Llc against peers pursuing similar technology classes.
