Portfolio overview

Sumitomo Electric Printed Circuits, Inc. has been granted 87 US utility patents between 2015 and 2025, placing Sumitomo Electric Printed Circuits, Inc. at rank #4,131 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, Sumitomo Electric Printed Circuits, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Sumitomo sits between Objectvideo Labs, Llc (87 patents, rank #4,127) and Shockwave Medical, Inc. (87 patents, rank #4,135) - the closest US assignees by grant volume. The composite Innovation Score of 48.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 62 grants, compared with 25 in the 2015–2019 window, a +148% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Sumitomo Electric Printed Circuits, Inc.'s 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sumitomo Electric Printed Circuits, Inc. against peers pursuing similar technology classes.
