Portfolio overview

LG CHEM, Ltd. has been granted 6,727 US utility patents between 2015 and 2025, placing LG CHEM, Ltd. at rank #56 across all assignees tracked by PlainPatent. This portfolio spans 278 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.9 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, LG CHEM, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, LG sits between KIA Motors Corporation (7,264 patents, rank #52) and 3M Innovative Properties Company (5,993 patents, rank #60) - the closest US assignees by grant volume. The composite Innovation Score of 66.9/100 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 3,629 grants, compared with 3,098 in the 2015–2019 window, a +17% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. LG CHEM, Ltd.'s 12.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LG CHEM, 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.
