Portfolio overview
Callminer, Inc. has been granted 10 US utility patents between 2016 and 2025, placing Callminer, Inc. at rank #26,014 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 21.2 claims per patent with primary concentration in G10L (SPEECH ANALYSIS TECHNIQUES OR SPEECH SYNTHESIS; SPEECH RECOGNITION; SPEECH OR VOICE PROCESSING TECHNIQUES; SPEECH OR AUDIO CODING OR DECODING). As a US Corporation, Callminer, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Callminer sits between Calabrio, Inc. (10 patents, rank #26,010) and Carr Lane Manufacturing Company (10 patents, rank #26,018) - the closest US assignees by grant volume. The composite Innovation Score of 29.8/100 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 8 grants, compared with 2 in the 2015–2019 window, a +300% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Callminer, Inc.'s 21.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Callminer, Inc. against peers pursuing similar technology classes.
