Portfolio overview

Shindengen Electric Manufacturing Co., Ltd. has been granted 242 US utility patents between 2015 and 2025, placing Shindengen Electric Manufacturing Co., Ltd. at rank #1,699 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Shindengen Electric Manufacturing Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Shindengen sits between Spring Meadow Nursery Inc. (243 patents, rank #1,695) and Roland Corporation (241 patents, rank #1,703) - the closest US assignees by grant volume. The composite Innovation Score of 53.3/100 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 117 grants, compared with 125 in the 2015–2019 window, a -6% 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. Shindengen Electric Manufacturing Co., Ltd.'s 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shindengen Electric Manufacturing 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.
