What this shows Kolen Co., Ltd. stamps GRANTS-SMALL, MID-PACK, PHOTO-FINISH, CPC-NARROW, INNOV-THIN, CLAIMS-RICH, TYPE-FRNCORP, VEL-DROP, BOOK-FULL. Volume places it #14,725 of 50,000; Innovation Score 26.5/100 sits in the top 80% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is KHD Humboldt Wedag Gmbh (±0 grants).
Kolen Co., Ltd. has been granted 20 US utility patents between 2015 and 2018, placing Kolen Co., Ltd. at #14,725 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Kolen Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kolen sits between KHD Humboldt Wedag Gmbh (20 patents, rank #14,713) and Koppers Performance Chemicals, Inc. (20 patents, rank #14,721) - the closest US assignees by grant volume. The composite Innovation Score of 26.5/100 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 0 grants, compared with 20 in the 2015–2019 window, a -100% 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. Kolen Co., Ltd.'s 14.9 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.
