Portfolio overview

Calyxia has been granted 9 US utility patents between 2020 and 2025, placing Calyxia at rank #28,320 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, Calyxia is one of the more focused assignees in the PatentsView dataset. By volume, Calyxia sits between Bury Sp.z.o.o. (9 patents, rank #28,316) and Cancer Hospital, Chinese Academy OF Medical Sciences (9 patents, rank #28,324) - the closest US assignees by grant volume. The composite Innovation Score of 33.9/100 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. Historical data spans 2020 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Calyxia's 13.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Calyxia against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
