Portfolio overview

Ranpak Corp. has been granted 79 US utility patents between 2015 and 2025, placing Ranpak Corp. at rank #4,485 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in B31D (MAKING ARTICLES OF PAPER, CARDBOARD OR MATERIAL WORKED IN A MANNER ANALOGOUS TO PAPER, NOT PROVIDED FOR IN SUBCLASSES B31B OR B31C). As a US Corporation, Ranpak Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Ranpak sits between Nissha Co., Ltd. (79 patents, rank #4,481) and Shifamed Holdings, Llc (79 patents, rank #4,489) - the closest US assignees by grant volume. The composite Innovation Score of 50.5/100 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 53 grants, compared with 26 in the 2015–2019 window, a +104% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. Ranpak Corp.'s 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ranpak Corp. 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.
