Portfolio overview

Circle Optics, Inc. has been granted 9 US utility patents between 2023 and 2025, placing Circle Optics, Inc. at rank #28,468 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.7 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a US Corporation, Circle Optics, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Circle sits between Christmas Northeast, Inc. (9 patents, rank #28,464) and Cleveland Heartlab, Inc. (9 patents, rank #28,472) - the closest US assignees by grant volume. The composite Innovation Score of 43.5/100 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 2023 through 2025, with 9 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. Circle Optics, Inc.'s 15.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Circle Optics, Inc. against peers pursuing similar technology classes.

How to use this portfolio

Circle's 9 grants land it in the top 28% 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 - Circle ranks #28,468 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G02B - see who else leads that technology area. G02B 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.
