Portfolio overview

Charcoal Companion Limited has been granted 37 US utility patents between 2015 and 2021, placing Charcoal Companion Limited at rank #8,559 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.5 claims per patent with primary concentration in A47J (KITCHEN EQUIPMENT; COFFEE MILLS; SPICE MILLS; APPARATUS FOR MAKING BEVERAGES). As a Foreign Corporation, Charcoal Companion Limited is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 21.7/100 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 35 in the 2015–2019 window — a -94% 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. Charcoal Companion Limited's 3.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Charcoal Companion Limited against peers pursuing similar technology classes.
