Portfolio overview

Mitsubishi Shindoh Co., Ltd. has been granted 39 US utility patents between 2015 and 2020, placing Mitsubishi Shindoh Co., Ltd. at rank #8,250 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, Mitsubishi Shindoh Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between Meijo University (39 patents, rank #8,246) and National Semiconductor Corporation (39 patents, rank #8,254) - the closest US assignees by grant volume. The composite Innovation Score of 37.2/100 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 4 grants, compared with 35 in the 2015–2019 window, a -89% 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. Mitsubishi Shindoh Co., Ltd.'s 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitsubishi Shindoh 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.
