Portfolio overview

Schweitzer Engineering Laboratories, Inc. has been granted 480 US utility patents between 2015 and 2025, placing Schweitzer Engineering Laboratories, Inc. at rank #929 across all assignees tracked by PlainPatent. This portfolio spans 75 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a US Corporation, Schweitzer Engineering Laboratories, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Schweitzer sits between SIKA Technology Ag (482 patents, rank #925) and Caterpillar Paving Products Inc. (476 patents, rank #933) - the closest US assignees by grant volume. The composite Innovation Score of 62.9/100 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 322 grants, compared with 158 in the 2015–2019 window, a +104% 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. Schweitzer Engineering Laboratories, Inc.'s 18.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 75 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Schweitzer Engineering Laboratories, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Schweitzer's 480 grants land it in the top 2% 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 - Schweitzer ranks #929 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01R - see who else leads that technology area. G01R 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.
