Portfolio overview

Bleistahl-produktions Gmbh & Co KG has been granted 5 US utility patents between 2017 and 2022, placing Bleistahl-produktions Gmbh & Co KG at rank #45,322 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, Bleistahl-produktions Gmbh & Co KG is one of the more focused assignees in the PatentsView dataset. By volume, Bleistahl-produktions sits between Blackstone International, Ltd. (5 patents, rank #45,318) and Bliss Point Media, Inc. (5 patents, rank #45,326) - the closest US assignees by grant volume. The composite Innovation Score of 28.3/100 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 2 grants, compared with 3 in the 2015–2019 window, a -33% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Bleistahl-produktions Gmbh & Co KG's 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bleistahl-produktions Gmbh & Co KG against peers pursuing similar technology classes.
