Portfolio overview

Ricoh Imaging Company, Ltd. has been granted 88 US utility patents between 2015 and 2021, placing Ricoh Imaging Company, Ltd. at rank #4,099 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.5 claims per patent with primary concentration in H04N (PICTORIAL COMMUNICATION, e.g. TELEVISION). As a Foreign Corporation, Ricoh Imaging Company, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ricoh sits between Netscout Systems, Inc. (88 patents, rank #4,095) and WIN Semiconductors Corp. (88 patents, rank #4,103) - the closest US assignees by grant volume. The composite Innovation Score of 38.6/100 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 3 grants, compared with 85 in the 2015–2019 window, a -96% 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. Ricoh Imaging Company, Ltd.'s 13.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ricoh Imaging Company, 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.
