#27,356
Across all tracked assignees
USPTO PatentsView assignee record - 10 granted patents across 9 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION).
The verdict
SK holds 10 US patents across 9 technology areas, rank #27,356 of 50,000 tracked assignees.
SK Nexilis Co., Ltd. has been granted 10 US utility patents between 2022 and 2025, placing SK Nexilis Co., Ltd. at rank #27,356 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 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, SK Nexilis Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SK sits between Silitek Electronics (dongguan) Co., Ltd (10 patents, rank #27,352) and SKY Motion Research, ULC (10 patents, rank #27,360) - the closest US assignees by grant volume. The composite Innovation Score of 44.5/100 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. Historical data spans 2022 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. SK Nexilis Co., Ltd.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SK Nexilis Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
SK's 10 grants land it in the top 25% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
