Caris Life Sciences Announces Allowances of Two New Patents for its Proprietary Offering Caris Molecular Intelligence

IRVING, Tex., Mar. 16, 2016 – Caris Life Sciences® today announced that the United States Patent and Trademark Office has recently provided notice of allowances for two of Caris’ pending patent applications: United States Patent Application Nos. 14/187,015 (“ ’015 Application”) and 14/249,261 (“ ’261 Application”). The patents that issue will provide intellectual property protection for Caris Molecular Intelligence® (CMI), the company’s patented and proprietary offering to help oncologists make informed therapy decisions, and strengthen the worldwide patent portfolio to 17 patents. The ’015 Application claims are directed to the molecular analysis of PTEN, CTNNB1, cKIT, BRAF and PIK3CA to identify therapeutic options for lung cancer, while the ’261 Application claims are directed to the molecular analysis of TOP1, TYMS, MGMT, PTEN, HER2, cMET, PIK3CA, KRAS, EGFR, PGP, RRM1, TLE3, TOP2A, cKIT and BRAF, utilizing sequencing, immunohistochemistry (IHC) and in situ hybridization (ISH) to identify therapeutic options for any cancer.
“With the addition of these patents, Caris now maintains an even more robust portfolio of intellectual property. Strong intellectual property protection is essential for biotechnology-based companies like Caris because it provides incentive to continue to invest in research and development,” said David D. Halbert, Chairman and CEO of Caris Life Sciences. “With the growing awareness of the importance of precision medicine in oncology as well as other fields, research and development is critical to advancing the field and improving patient care.”
The recently allowed patent applications are part of Caris’ intellectual property portfolio, which includes an additional nine issued U.S. patents and six foreign patents that also provide intellectual property protection for CMI. The nine U.S. patents have claims that are generally directed to molecular analysis of various sample types for various biomarkers, as follows in table below.
