Patientory (PTOY)

Patientory is a healthcare technology company founded by Chrissa McFarlane that provides a blockchain-based platform and issues the PTOY token. In March 2018 its brand colors shifted from red to green following legal battles with the Red Cross and Blue Cross Blue Shield.

Patientory is a healthcare technology company that provides a blockchain-based platform for securely storing and managing health information. Founded by Chrissa McFarlane, the company operates under the Patientory, Inc. brand and issues the PTOY token, which facilitates transactions on its platform. The company’s visual identity has undergone a documented color shift driven by legal disputes over its original mark.

Design and History

The current Patientory logo consists of a green and black cross with a green leaflet on the upper right column, accompanied by the wordmark “patientory” to the right of the symbol. A trademark filing for “PATIENTORY STIFTUNG” describes the mark in these terms and claims green and black as features of the mark.[1]

The most significant documented change to the Patientory identity occurred in early 2018. According to a company press release, Patientory Stiftung and Patientory Inc. unveiled a brand makeover in March 2018, shifting their brand colors from red to green. The release states that “the red logo is a thing of the past after months of legal battles with the Red Cross and Blue Cross Blue Shield.”[2] The same announcement introduced new leadership for the Patientory Stiftung, the Swiss non-profit responsible for the blockchain infrastructure behind Patientory, Inc.[2]

Around the same period, the Patientory Stiftung was rebranded as the Patientory Association, a global nonprofit healthcare member organization, and relocated its operations to San Francisco.[3]

Meaning and Symbolism

The cross element in the Patientory logo directly references healthcare and medical care, while the green leaflet on the upper right column adds a natural, health-oriented accent. The trademark registration for the mark explicitly documents these visual components: “a green and black cross with a green leaflet on the upper right column.”[1]

Typography and Design

The Patientory wordmark appears in lowercase letters to the right of the cross symbol, with the term “stiftung” placed below the last four letters of “patientory” in the trademark filing for the Swiss foundation.[1] The company’s current branding, as seen on its official website, uses the green cross and leaflet symbol alongside the “patientory” wordmark.[4]
