Portfolio overview

Carbo Ceramics, Inc. has been granted 89 US utility patents between 2015 and 2025, placing Carbo Ceramics, Inc. at rank #4,033 across all assignees tracked by PlainPatent. This portfolio spans 25 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.0 claims per patent with primary concentration in C09K (MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE). As a US Corporation, Carbo Ceramics, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Carbo sits between B-K Medical APS (89 patents, rank #4,029) and Deroyal Industries, Inc. (89 patents, rank #4,037) - the closest US assignees by grant volume. The composite Innovation Score of 49.5/100 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 53 grants, compared with 36 in the 2015–2019 window, a +47% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Carbo Ceramics, Inc.'s 19.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 25 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Carbo Ceramics, Inc. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
