Biocept Awarded Patent in Japan for the Capture of Rare Cells Including CTCs from Any Biological Sample of Interest with A Microchannel Device


SAN DIEGO, March 18, 2019 — Biocept, Inc. (NASDAQ: BIOC), a leading commercial provider of liquid biopsy tests designed to provide physicians with clinically actionable information to improve the outcomes of patients diagnosed with cancer, announces that it has been awarded Japanese Patent No. 6463668 entitled, DEVICES AND METHODS OF CELL CAPTURE AND ANALYSIS. The issued patent covers a microchannel device and antibodies for the capture of rare cells of interest, including CTCs that are shed into the blood stream by solid tumors. Biocept believes the newly granted patent has claims that encompass any biological sample type of interest, and is the 32nd patent issued to Biocept that is core to its liquid biopsy technology platforms.

“The granting of this patent further expands internationally Biocept’s platform for capturing and analyzing rare cells from biological fluids, such as blood, bone marrow, cerebral spinal fluid (CSF), and tissue, to assess the status of patients with cancer,” said Lyle Arnold, Ph.D., Chief Scientific Officer at Biocept.  “This technology interfaces well with Biocept’s other patented liquid biopsy technologies, including the Company’s blood collection tube, and ctDNA analysis platform for providing information to aid physicians in the treatment of their patients with cancer.”

The technology covered by this issued patent combines Biocept’s patented microchannel platform together with antibodies to enable the capture of rare cells of interest. These technologies combine to enable the capture of cells that are present in very low numbers from blood and other biological fluids.

Michael Nall, Biocept’s President and CEO, added, “Obtaining this new patent provides additional intellectual property protection for the unique and novel features of our Target Selector™ platform, featuring our microchannel and antibody capture technologies for CTCs and other rare cells of interest. We believe that additional global intellectual property expands the opportunity for Biocept to generate revenue in territories outside the U.S.”
