Portfolio overview

Eickhof Columbaria, Inc. has been granted 9 US utility patents between 2015 and 2020, placing Eickhof Columbaria, Inc. at rank #28,676 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in E04H (BUILDINGS OR LIKE STRUCTURES FOR PARTICULAR PURPOSES; SWIMMING OR SPLASH BATHS OR POOLS; MASTS; FENCING; TENTS OR CANOPIES, IN GENERAL). As a US Corporation, Eickhof Columbaria, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Eickhof sits between Easton Baseball/softball Inc. (9 patents, rank #28,672) and Electrosea, Llc (9 patents, rank #28,680) - the closest US assignees by grant volume. The composite Innovation Score of 17.3/100 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 3 grants, compared with 6 in the 2015–2019 window, a -50% 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. Eickhof Columbaria, Inc.'s 7.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Eickhof Columbaria, Inc. against peers pursuing similar technology classes.
