Portfolio overview
Carpin Manufacturing, Inc. has been granted 5 US utility patents between 2016 and 2021, placing Carpin Manufacturing, Inc. at rank #45,753 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.0 claims per patent with primary concentration in F16B (DEVICES FOR FASTENING OR SECURING CONSTRUCTIONAL ELEMENTS OR MACHINE PARTS TOGETHER, e.g. NAILS, BOLTS, CIRCLIPS, CLAMPS, CLIPS OR WEDGES; JOINTS OR JOINTING). As a US Corporation, Carpin Manufacturing, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Carpin sits between Carl Zeiss Optotechnik Gmbh (5 patents, rank #45,749) and Cassida Corporation (5 patents, rank #45,757) - the closest US assignees by grant volume. The composite Innovation Score of 21.9/100 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 1 grants, compared with 4 in the 2015–2019 window, a -75% 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. Carpin Manufacturing, Inc.'s 13.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Carpin Manufacturing, Inc. against peers pursuing similar technology classes.
