Portfolio overview

Buckman Laboratories International, Inc. has been granted 35 US utility patents between 2015 and 2025, placing Buckman Laboratories International, Inc. at rank #8,993 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.3 claims per patent with primary concentration in D21H (PULP COMPOSITIONS; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D; IMPREGNATING OR COATING OF PAPER; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G; PAPER NOT OTHERW). As a US Corporation, Buckman Laboratories International, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Buckman sits between Biodesix, Inc. (35 patents, rank #8,989) and CFD Research Corporation (35 patents, rank #8,997) - the closest US assignees by grant volume. The composite Innovation Score of 56.9/100 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 16 grants, compared with 19 in the 2015–2019 window, a -16% 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. Buckman Laboratories International, Inc.'s 20.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Buckman Laboratories International, Inc. against peers pursuing similar technology classes.
