Portfolio overview

Denki Kogyo Company, Limited has been granted 7 US utility patents between 2016 and 2023, placing Denki Kogyo Company, Limited at rank #34,949 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in H01Q (ANTENNAS, i.e. RADIO AERIALS). As a Foreign Corporation, Denki Kogyo Company, Limited is one of the more focused assignees in the PatentsView dataset. By volume, Denki sits between Delcon S.r.l. (7 patents, rank #34,945) and DER Sheng Co., Ltd (7 patents, rank #34,953) - the closest US assignees by grant volume. The composite Innovation Score of 26.1/100 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 2 grants, compared with 5 in the 2015–2019 window, a -60% 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. Denki Kogyo Company, Limited's 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Denki Kogyo Company, Limited against peers pursuing similar technology classes.
