Portfolio overview

Silgan Containers Llc has been granted 56 US utility patents between 2015 and 2025, placing Silgan Containers Llc at rank #6,078 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.4 claims per patent with primary concentration in B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F). As a US Corporation, Silgan Containers Llc is one of the more focused assignees in the PatentsView dataset. By volume, Silgan sits between Storagecraft Technology Corporation (56 patents, rank #6,074) and Toshiba Carrier Corporation (56 patents, rank #6,082) - the closest US assignees by grant volume. The composite Innovation Score of 36.0/100 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 26 grants, compared with 30 in the 2015–2019 window, a -13% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Containers Llc's 6.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Silgan Containers Llc against peers pursuing similar technology classes.
