Portfolio overview

Silgan Dispensing Systems Corporation has been granted 109 US utility patents between 2017 and 2025, placing Silgan Dispensing Systems Corporation at rank #3,409 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 claims per patent with primary concentration in B05B (SPRAYING APPARATUS; ATOMISING APPARATUS; NOZZLES). As a US Corporation, Silgan Dispensing Systems Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Silgan sits between Rittal Gmbh & Co. KG (109 patents, rank #3,405) and Storedot, Ltd. (109 patents, rank #3,413) - the closest US assignees by grant volume. The composite Innovation Score of 44.4/100 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 77 grants, compared with 32 in the 2015–2019 window, a +141% 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. Silgan Dispensing Systems Corporation's 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silgan Dispensing Systems Corporation 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.
