What this shows SK Hynix System Ic Inc. stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-NARROW, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #20,434 of 50,000; Innovation Score 28.5/100 sits in the top 72% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Siliconfile Technologies Inc. (±0 grants).
SK Hynix System Ic Inc. has been granted 14 US utility patents between 2017 and 2024, placing SK Hynix System Ic Inc. at #20,434 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, SK Hynix System Ic Inc. is one of the more focused assignees in the PatentsView dataset. By volume, SK sits between Siliconfile Technologies Inc. (14 patents, rank #20,385) and Smartrac I.p. B.v. (14 patents, rank #20,393) - the closest US assignees by grant volume. The composite Innovation Score of 28.5/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 9 grants, compared with 5 in the 2015–2019 window, a +80% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. SK Hynix System Ic Inc.'s 15.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 4 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
