Portfolio overview
Sanyo Denki Co., Ltd. has been granted 114 US utility patents between 2015 and 2025, placing Sanyo Denki Co., Ltd. at rank #3,290 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Sanyo Denki Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sanyo sits between Maschinenfabrik Rieter Ag (114 patents, rank #3,286) and Versalis S.p.a. (114 patents, rank #3,294) - the closest US assignees by grant volume. The composite Innovation Score of 51.3/100 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 44 grants, compared with 70 in the 2015–2019 window, a -37% 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. Sanyo Denki Co., Ltd.'s 8.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sanyo Denki Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Sanyo's 114 grants land it in the top 12% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Sanyo ranks #3,290 of 50,000. Top 50 holders
- Most of this portfolio concentrates in H02K - see who else leads that technology area. H02K leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
