Portfolio overview

Tatsuta Electric WIRE & Cable Co., Ltd. has been granted 83 US utility patents between 2016 and 2025, placing Tatsuta Electric WIRE & Cable Co., Ltd. at rank #4,305 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 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, Tatsuta Electric WIRE & Cable Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tatsuta sits between NHN Corporation (83 patents, rank #4,301) and Theranos, Inc. (83 patents, rank #4,309) - the closest US assignees by grant volume. The composite Innovation Score of 49.1/100 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 21 in the 2015–2019 window, a +195% 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. Tatsuta Electric WIRE & Cable Co., Ltd.'s 8.0 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 Tatsuta Electric WIRE & Cable Co., Ltd. against peers pursuing similar technology classes.
