Portfolio overview

Posco LED Company Ltd. has been granted 10 US utility patents between 2015 and 2016, placing Posco LED Company Ltd. at rank #27,166 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.9 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, Posco LED Company Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Posco sits between Pliant Energy Systems Inc. (10 patents, rank #27,162) and Power8 Tech. Inc. (10 patents, rank #27,170) - the closest US assignees by grant volume. The composite Innovation Score of 26.6/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Posco LED Company Ltd.'s 12.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Posco LED Company Ltd. against peers pursuing similar technology classes.

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.
