Across all tracked assignees
USPTO PatentsView assignee record - 772 granted patents across 45 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H04W (WIRELESS COMMUNICATION NETWORKS).
The verdict
SK holds 772 US patents across 45 technology areas, rank #579 of 50,000 tracked assignees.
SK Telecom Co., Ltd. has been granted 772 US utility patents between 2015 and 2025, placing SK Telecom Co., Ltd. at rank #579 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.5 claims per patent with primary concentration in H04W (WIRELESS COMMUNICATION NETWORKS). As a Foreign Corporation, SK Telecom Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SK sits between Snecma (783 patents, rank #575) and Globalfoundries Singapore Pte. Ltd. (769 patents, rank #583) - the closest US assignees by grant volume. The composite Innovation Score of 64.0/100 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 450 grants, compared with 322 in the 2015–2019 window, a +40% 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. SK Telecom Co., Ltd.'s 11.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SK Telecom Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
SK's 772 grants land it in the top 2% 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.
