Portfolio overview
Blach Construction Company has been granted 7 US utility patents between 2020 and 2025, placing Blach Construction Company at rank #34,553 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in E04B (GENERAL BUILDING CONSTRUCTIONS; WALLS, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; INSULATION OR OTHER PROTECTION OF BUILDINGS). As a US Corporation, Blach Construction Company is one of the more focused assignees in the PatentsView dataset. By volume, Blach sits between Bioz, Inc. (7 patents, rank #34,549) and Blackjack Production Tools, Llc (7 patents, rank #34,557) - the closest US assignees by grant volume. The composite Innovation Score of 29.6/100 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. Historical data spans 2020 through 2025, with 7 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Blach Construction Company's 14.4 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 Blach Construction Company against peers pursuing similar technology classes.
