Portfolio overview
Vamco International, Inc. has been granted 6 US utility patents between 2015 and 2017, placing Vamco International, Inc. at rank #43,861 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.0 claims per patent with primary concentration in B21D (WORKING OR PROCESSING OF SHEET METAL OR METAL TUBES, RODS OR PROFILES WITHOUT ESSENTIALLY REMOVING MATERIAL; PUNCHING METAL). As a US Corporation, Vamco International, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Vamco sits between VALE MILL (rochdale) Limited (6 patents, rank #43,857) and Vectorious Medical Technologies Ltd. (6 patents, rank #43,865) - the closest US assignees by grant volume. The composite Innovation Score of 25.2/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% 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. Vamco International, Inc.'s 19.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Vamco International, Inc. against peers pursuing similar technology classes.
