Portfolio overview

Posco Energy Co., Ltd. has been granted 8 US utility patents between 2016 and 2019, placing Posco Energy Co., Ltd. at rank #32,920 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Posco Energy Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Posco sits between Pop Vriend Research B.v. (8 patents, rank #32,916) and Poynting Antennas (pty) Limited (8 patents, rank #32,924) - the closest US assignees by grant volume. The composite Innovation Score of 28.4/100 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 8 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 Energy Co., Ltd.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Posco Energy Co., 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.
