Portfolio overview

Zephyr Photonics Inc. has been granted 11 US utility patents between 2015 and 2021, placing Zephyr Photonics Inc. at rank #25,574 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 34.8 claims per patent with primary concentration in H04B (TRANSMISSION). As a US Corporation, Zephyr Photonics Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Zephyr sits between York Guangzhou Air Conditioning And Refrigeration Co., Ltd. (11 patents, rank #25,570) and Zinitix Co., Ltd. (11 patents, rank #25,578) - the closest US assignees by grant volume. The composite Innovation Score of 36.8/100 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 1 grants, compared with 10 in the 2015–2019 window, a -90% 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. Zephyr Photonics Inc.'s 34.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zephyr Photonics Inc. against peers pursuing similar technology classes.

How to use this portfolio

Zephyr's 11 grants land it in the top 45% 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 - Zephyr ranks #25,574 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04B - see who else leads that technology area. H04B 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.
