What this shows Samhwa Co., Ltd stamps GRANTS-SMALL, MID-PACK, PHOTO-FINISH, CPC-NARROW, INNOV-PAR, CLAIMS-SPARSE, TYPE-FRNCORP, SPAN-YRS, BOOK-RICH. Volume places it #13,138 of 50,000; Innovation Score 44.3/100 sits in the top 26% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Roche Palo Alto Llc (±0 grants).
Samhwa Co., Ltd has been granted 23 US utility patents between 2020 and 2025, placing Samhwa Co., Ltd at #13,138 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in A45D (HAIRDRESSING OR SHAVING EQUIPMENT ; EQUIPMENT FOR COSMETICS OR COSMETIC TREATMENTS, e.g. FOR MANICURING OR PEDICURING). As a Foreign Corporation, Samhwa Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Samhwa sits between Roche Palo Alto Llc (23 patents, rank #13,127) and Sensory, Incorporated (23 patents, rank #13,135) - the closest US assignees by grant volume. The composite Innovation Score of 44.3/100 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. Historical data spans 2020 through 2025, with 23 total grants over that period. 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. Samhwa Co., Ltd's 7.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 6 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
