Portfolio overview

Energizer Auto, Inc. has been granted 22 US utility patents between 2021 and 2025, placing Energizer Auto, Inc. at rank #13,408 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in F25B (REFRIGERATION MACHINES, PLANTS OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS). As a US Corporation, Energizer Auto, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Energizer sits between Element 1 Corp (22 patents, rank #13,404) and Epirus, Inc. (22 patents, rank #13,412) - the closest US assignees by grant volume. The composite Innovation Score of 41.7/100 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. Historical data spans 2021 through 2025, with 22 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. Energizer Auto, Inc.'s 7.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Energizer Auto, Inc. 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.
