Portfolio overview

EIE Materials, Inc. has been granted 5 US utility patents between 2018 and 2019, placing EIE Materials, Inc. at rank #46,390 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.4 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a US Corporation, EIE Materials, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, EIE sits between Egg-chick Automated Technologies (5 patents, rank #46,386) and EKPO Fuel Cell Technologies Gmbh (5 patents, rank #46,394) - the closest US assignees by grant volume. The composite Innovation Score of 31.4/100 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 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 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. EIE Materials, Inc.'s 22.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EIE Materials, Inc. against peers pursuing similar technology classes.

How to use this portfolio

EIE's 5 grants land it in the top 62% 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 - EIE ranks #46,390 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H10H - see who else leads that technology area. H10H 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.
