Portfolio overview
Dummen Group B.v. has been granted 87 US utility patents between 2015 and 2025, placing Dummen Group B.v. at rank #4,115 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.1 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a Foreign Corporation, Dummen Group B.v. is one of the more focused assignees in the PatentsView dataset. By volume, Dummen sits between Compagnie Plastic Omnium SE (87 patents, rank #4,111) and Hunter's Manufacturing Company, Inc. (87 patents, rank #4,119) - the closest US assignees by grant volume. The composite Innovation Score of 41.1/100 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 82 grants, compared with 5 in the 2015–2019 window, a +1540% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Dummen Group B.v.'s 1.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dummen Group B.v. against peers pursuing similar technology classes.
