Biocept Expands U.S. Microchannel Patent Protection

Fifth issued U.S. patent covers the use of antibodies in the capture and detection of rare cells from biological fluids with Biocept's microchannel capture device

SAN DIEGO--(BUSINESS WIRE)-- Biocept, Inc. (NASDAQ: BIOC), a molecular diagnostics company commercializing and developing liquid biopsies to improve the detection and treatment of cancer, announces the allowance of U.S. Patent 9,128,082 entitled, DEVICES AND METHODS OF CELL CAPTURE AND ANALYSIS. The patent covers the use of antibodies in the capture of cells such as circulating tumor cells (CTCs) from blood, as well as other biological fluids, using the company's patented microchannel capture device. Biocept's antibody capture cocktail along with the microchannel are key components of the company's Cell Enrichment and Extraction (CEE™) platform, providing for the high-efficiency capture, visualization and microscopic analysis of targeted cells obtained from a patient blood sample and used by physicians for medical decision making.

Lyle Arnold, Ph.D., Chief Scientific Officer at Biocept, said, "The issuance of this patent expands Biocept's patent portfolio to include the use of antibodies in the capture of cancer cells in combination with our microchannel for which multiple U.S. and international patents have been granted. Our antibody cocktail is a key part of our patented and proprietary method to capture and analyze cells from a wide variety of tumor types. In addition, this patent expands our IP protection for the use of a simple blood sample, and other biological sample types, in obtaining valuable biomarker information that can be used by physicians to personalize treatment of individual patients."

"We have been aggressively broadening our IP protection for our unique methods of capturing and analyzing cancer cells in blood and other biological fluids," said Biocept's President and Chief Executive Officer, Michael Nall. "Our portfolio of U.S. and international patents better positions Biocept to capitalize on the growing movement toward the use of liquid biopsy, which can reduce healthcare system costs and importantly help patients qualify for treatments that physicians can utilize to treat their cancer."
