What this shows CHUO Hatsujo Kabushiki Kaisha stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-THIN, CLAIMS-PAR, TYPE-FRNCORP, VEL-UP, BOOK-FULL. Volume places it #15,188 of 50,000; Innovation Score 39.3/100 sits in the top 38% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Chimerix, Inc. (±0 grants).
CHUO Hatsujo Kabushiki Kaisha has been granted 19 US utility patents between 2015 and 2025, placing CHUO Hatsujo Kabushiki Kaisha at #15,188 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in F16F (SPRINGS; SHOCK-ABSORBERS; MEANS FOR DAMPING VIBRATION). As a Foreign Corporation, CHUO Hatsujo Kabushiki Kaisha is one of the more focused assignees in the PatentsView dataset. By volume, CHUO sits between Chimerix, Inc. (19 patents, rank #15,175) and Cochrane USA Inc. (19 patents, rank #15,183) - the closest US assignees by grant volume. The composite Innovation Score of 39.3/100 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. Between 2020 and 2024 the company received 10 grants, compared with 8 in the 2015–2019 window, a +25% 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. CHUO Hatsujo Kabushiki Kaisha's 9.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 28 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
