Portfolio overview

CH LIGHTING TECHNOLOGY CO., LTD. has been granted 19 US utility patents between 2018 and 2025, placing CH LIGHTING TECHNOLOGY CO., LTD. at rank #15,172 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.6 claims per patent with primary concentration in F21Y (INDEXING SCHEME ASSOCIATED WITH SUBCLASSES F21K, F21L, F21S and F21V, RELATING TO THE FORM OR THE KIND OF THE LIGHT SOURCES OR OF THE COLOUR OF THE LIGHT EMITTED). As a Foreign Corporation, CH LIGHTING TECHNOLOGY CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.9/100 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 16 grants, compared with 3 in the 2015–2019 window, a +433% 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. CH LIGHTING TECHNOLOGY CO., LTD.'s 15.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CH LIGHTING TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.

Guides to patent portfolio analysis

How to use this portfolio

CH's 19 grants land it in the top 11% 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 - CH ranks #15,172 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F21Y - see who else leads that technology area. F21Y 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.
