PharmaSeq Receives U.S. Patent for p-Chip Tagging and Anatomical Pathology Storage

Monmouth Junction, NJ, April 10, 2017. PharmaSeq, Inc., announced today that it has received U.S. patent (9,582,688) for “Electronic Chip-Based Tagging System for Identifying Closely Proximate Thin and Flat Items.” The patent concerns the use of PharmaSeq’s p-Chip® technology in applications where very large quantities of specimens are stored and retrieved as part of workflow, such as in anatomical pathology. The patent specifically covers a unique design of a device that enables p-Chips glued to the edges of individual glass microscope slides or tissue cassettes to be read when they are in close proximity to one another, such as in storage trays. The device makes it possible to locate a single item very rapidly and effectively. PharmaSeq’s technology eliminates the need to remove samples from drawers to read their barcode, thereby improving workflow, reducing errors and decreasing costs in histopathology laboratories.

The current issuance builds on a previous patent (9,418,321) granted to PharmaSeq in 2016 that covers the basic concepts involved with tagging tissue carriers and glass slides with p-Chips. Both patents were developed under a Fast Track Small Business Innovative Research (SBIR) grant from the National Cancer Institute. The goal of the SBIR project was to develop a highly reliable, cost-effective system to replace traditional barcode labeling systems for tissue cassettes and glass slides with a highly ruggedized method that uses identity numbers (IDs) stored electronically in p-Chips as keys for accessing specimen information in a database.

PharmaSeq’s patented p-Chip is a highly durable semiconductor device that is stable over a wide range of temperatures and resilient to the various harsh reagents used to process medical samples. The very small size of the p-Chips makes it possible to attach or embed them directly onto plastic tissue cassettes and glass microscope slides. Because each p-Chip has a unique ID, it is possible to associate every specimen with the patient from which it was obtained.

Dr. Richard Morris, CEO of PharmaSeq, commented: “The issuance of this second patent related to applications in anatomical pathology further validates the value of p-Chip technology in this field. The development of an efficient, rapid reading method completes the system needed to maintain and retrieve samples from large storage libraries.” He continued: “The combination of p-Chips tagging along with this new patent provides end-to-end coverage of PharmaSeq’s system for sample management in pathology applications.”

About PharmaSeq. PharmaSeq, Inc., has developed an ultra-small microtransponder tag called the p-Chip that is poised to revolutionize several billion-dollar industries. The p-Chip is the smallest, most technologically advanced commercial product available today for tagging and authenticating consumer goods, industrial goods and small animals. Its size is at least 100-fold smaller than current gold standard RFID tags, and it costs far less to manufacture in volume—an order of magnitude less expensive than tags commonly used today. The p-Chip is nearly impossible to counterfeit and can be used reliably in environmentally challenging conditions ranging from -190°C to more than 150°C. These four unique capabilities of the p-Chip significantly expand the addressable market for this highly advanced, foundational technology.
