Portfolio overview

Chian YIH Optotech Co., Ltd. has been granted 10 US utility patents between 2018 and 2024, placing Chian YIH Optotech Co., Ltd. at rank #25,963 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.6 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, Chian YIH Optotech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Chian sits between Centerline Biomedical, Inc. (10 patents, rank #25,959) and Chromocell Corporation (10 patents, rank #25,967) - the closest US assignees by grant volume. The composite Innovation Score of 32.5/100 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. Between 2020 and 2025 the company received 7 grants, compared with 3 in the 2015–2019 window, a +133% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Chian YIH Optotech Co., Ltd.'s 21.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Chian YIH Optotech Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Chian's 10 grants land it in the top 59% 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 - Chian ranks #25,963 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F21S - see who else leads that technology area. F21S 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.
