("PolarityTE" or the "Company") (NASDAQ: COOL) purports to be a commercial-stage biotechnology and regenerative biomaterials company focused on discovering, designing and developing a range of regenerative tissue products and biomaterials for the fields of medicine, biomedical engineering and material sciences.

On June 27, 2018, Plaintiff's law firm issued a press release announcing the law suit. According to the press release, on June 25, 2018, Citron Research ("Citron") issued a report in which Citron detailed the Company's track record of material misrepresentations, misstatements, and omissions pertaining to the status of a key patent application. The Citron report noted that as far back as March 31, 2017, the USPTO notified the Company of its non-final rejection of patent #14/954,335. Citron's report continued to highlight the Company's subsequent failure to disclose the patent's non-final rejection status and its continued behavior of representing the technology linked to the patent in a positive light. The report also pointed to the USPTO's final rejection of the patent on June 4, 2018 – information that the Company also failed to disclose. On this news, COOL stock plunged more than 34%.

The Complaint alleges that between March 31, 2017 and June 25, 2018, inclusive (the "Class Period"), Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company's business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failures to disclose pertaining to a number of topics, including (i) the status of Patent #14/954,335 at the time it was acquired by the Company on April 7, 2017 and the months following; (ii) the updated status of Patent #14/954,335 after its June 4, 2018 final rejection by the USPTO; and (iii) that as a result of the foregoing, PolarityTE's publicly disseminated financial statements were materially false and misleading.
