Portfolio overview

Ethertronics, Inc has been granted 163 US utility patents between 2015 and 2022, placing Ethertronics, Inc at rank #2,395 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.1 claims per patent with primary concentration in H01Q (ANTENNAS, i.e. RADIO AERIALS). As a US Corporation, Ethertronics, Inc is one of the more focused assignees in the PatentsView dataset. By volume, Ethertronics sits between X-celeprint Limited (164 patents, rank #2,391) and Interdesign, Inc. (163 patents, rank #2,399) - the closest US assignees by grant volume. The composite Innovation Score of 43.2/100 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 43 grants, compared with 120 in the 2015–2019 window, a -64% 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. Ethertronics, Inc's 13.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 24 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ethertronics, Inc against peers pursuing similar technology classes.

How to use this portfolio

Ethertronics's 163 grants land it in the top 29% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Ethertronics ranks #2,395 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H01Q - see who else leads that technology area. H01Q leaders
  • 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.
