Portfolio overview

Sumitomo Electric FINE Polymer, Inc. has been granted 46 US utility patents between 2015 and 2025, placing Sumitomo Electric FINE Polymer, Inc. at #7,199 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.9 claims per patent with primary concentration in B32B (LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM). As a Foreign Corporation, Sumitomo Electric FINE Polymer, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Sumitomo sits between Smart Power Co., Ltd. (46 patents, rank #7,190) and Sonatus, Inc. (46 patents, rank #7,198) - the closest US assignees by grant volume. The composite Innovation Score of 44.5/100 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 10 grants, compared with 33 in the 2015–2019 window, a -70% 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. Sumitomo Electric FINE Polymer, Inc.'s 6.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 43 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
