Portfolio overview

SWCC Showa Cable Systems Co., Ltd. has been granted 11 US utility patents between 2015 and 2022, placing SWCC Showa Cable Systems Co., Ltd. at rank #25,210 across all assignees tracked by PlainPatent. This portfolio spans 19 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in H01B (CABLES; CONDUCTORS; INSULATORS; SELECTION OF MATERIALS FOR THEIR CONDUCTIVE, INSULATING OR DIELECTRIC PROPERTIES). As a Foreign Corporation, SWCC Showa Cable Systems Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, SWCC sits between Suzhou Huazao Shunwei Intelligent Technology Co., Ltd. (11 patents, rank #25,206) and Syntest Technologies, Inc. (11 patents, rank #25,214) - the closest US assignees by grant volume. The composite Innovation Score of 31.9/100 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 1 grants, compared with 10 in the 2015–2019 window, a -90% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. SWCC Showa Cable Systems Co., Ltd.'s 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 19 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SWCC Showa Cable Systems Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
