Biocept Awarded Broad Japanese Patent for the Use of Binding Entities in Combination with any Solid Surface to Capture and Detect any Target of Interest, including CTCs, from any Sample Type

Biocept further expands its patent estate for capturing and detecting target cells of interest, including CTCs


SAN DIEGO, Nov. 5, 2020 /PRNewswire/ -- Biocept, Inc. (Nasdaq: BIOC), a leading commercial provider of molecular diagnostic tests, products and services designed to provide physicians with clinically actionable information to improve patient outcomes, announces that it has been awarded Japanese Patent No. 6771010 entitled, DEVICES AND METHODS OF CELL CAPTURE AND ANALYSIS. The issued patent covers devices for the detection of any target of interest, including circulating tumor cells (CTCs) that are shed into the blood stream by solid tumors where a binding entity, including antibodies or mixture of binding entities, or antibodies and any solid surface are used for target capture, detection, and analysis. This patent includes any biological sample type of interest and includes the use of single entities or cocktails of binding entities.

The claims covered by this patent broadly include the use of binding entities for the capture and detection of any target of interest on any solid surface. It also covers combinations of antibodies for capturing a wide variety of different tumor types. This includes CTCs, as well as any other targets of interest. This patent combines well with Biocept's patented microchannel and cell staining platforms. These technologies combine to enable the capture of any cell of interest, including very rare cells, that may be present in blood and any other biological sample type.

"The granting of this Japanese patent broadly expands Biocept's intellectual property estate for capturing and detecting cells of interest," said Michael Nall, Biocept's President and CEO. "The patent also interfaces very well with our other patented technologies that include our blood collection tube as well as our Target Selectorâ„¢ circulating DNA (ctDNA) analysis platforms used for guiding patient treatment decisions. We believe the broad coverage of this patent also provides Biocept with the opportunity for potentially out-licensing the technology to other companies with a focus on any target of interest, including single cell analysis and other methodologies."
