Organization and Description of Business	Note 1. Organization and Description of Business Organization and Description of Business Spherix Incorporated (the “Company”) is an intellectual property company incorporated in the State of Delaware that owns patented and unpatented intellectual property. The Company was formed in 1967 as a scientific research company and for much of its history pursued drug development including through Phase III clinical studies which were discontinued. Through the Company’s acquisition of patents and patent applications developed by Nortel Networks Corporation from Rockstar Consortium US, LP (“Rockstar”) and Harris Corporation from North South Holdings Inc. (“North South”) in 2013, the Company has expanded its activities. The Company is a patent commercialization company focused on generating revenues from the monetization of intellectual property, or IP. Such monetization includes, but is not limited to, acquiring IP from patent holders in order to maximize the value of the patent holdings by conducting and managing a licensing campaign, or through the settlement and litigation of patents. We intend to generate revenues and related cash flows from the granting of intellectual property rights for the use of patented technologies that we own, that we manage for others, or that others manage on our behalf. To date, we have generated minimal revenues and no assurance can be provided that our business model will be successful. The Company continually works to enhance its portfolio of intellectual property through acquisition and strategic partnerships. The Company’s mission is to partner with inventors, or other entities, who own undervalued intellectual property. The Company then works with the inventors or other entities to commercialize the IP. In March 2016, the Company entered into an agreement (which was subsequently amended in April and May 2016) with Equitable IP Corporation (“Equitable”) to facilitate the monetization of its patents (the “Monetization Agreement”). Pursuant to the Monetization Agreement, the Company is working together with Equitable to further develop and revise its ongoing litigation plan. See Note 4 for additional details surrounding the Monetization Agreement. Reverse Stock Split and Amendment to Certificate of Incorporation The Company’s common stock is listed on the NASDAQ Capital Market under the symbol “SPEX.” One of the requirements for continued listing on the NASDAQ Capital Market is maintenance of a minimum closing bid price of $1.00 per share. On March 24, 2015, the Company received a letter (the “Notice”) from the Listing Qualifications Staff of The NASDAQ Stock Market LLC (“NASDAQ”) notifying the Company that, based upon the closing bid price of the Company’s common stock, $0.0001 par value per share (the “Common Stock”) for the 30 consecutive business days preceding receipt of such letter, the Common Stock had no longer met the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in NASDAQ Listing Rule 5550(a)(2). In accordance with NASDAQ’s Listing Rule 5810(c)(3)(A), the Company initially had a period of 180 calendar days, or until September 21, 2015, to regain compliance with the Rule. After determining that it would not be in compliance with the Rule by September 21, 2015, the Company notified NASDAQ and applied for an extension of the cure period, as permitted under the original notification. In accordance with NASDAQ Listing Rule 5810(c)(3)(A), NASDAQ granted a second grace period of 180 calendar days, or until March 21, 2016, to regain compliance with the minimum closing bid price requirement for continued listing. On February 26, 2016, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation and authorized the Company’s Board of Directors to effect a reverse stock split of Common Stock at a ratio in the range of 1-for-12 to 1-for-24. The Company implemented this reverse stock split on March 4, 2016 with a ratio of 1-for-19 (the “Reverse Stock Split”). No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the Reverse Stock Split received a cash payment in lieu thereof. The par value and other terms of the common stock were not affected by the Reverse Stock Split. In addition, the amendment to the Company’s certificate of incorporation that effected the Reverse Stock Split also simultaneously reduced the number of authorized shares of Common Stock from 200,000,000 to 100,000,000. The Company’s Common Stock began trading at its post-Reverse Stock Split price at the beginning of trading on March 4, 2016. On March 18, 2016, the Company received a letter from NASDAQ indicating that it had regained compliance with the minimum bid price requirement under NASDAQ Listing Rule 5550(a)(2) for continued listing on The NASDAQ Capital Market. The Company’s common stock continues to be listed on the NASDAQ Capital Market. Immediately following the Reverse Stock Split, the number of outstanding shares of Common Stock were reduced from 48,259,430 shares to 2,539,847. All per share amounts and outstanding shares of Common Stock including stock options, restricted stock and warrants, have been retroactively adjusted in these consolidated financial statements for all periods presented to reflect the 1-for-19 Reverse Stock Split. Further, exercise prices of stock options and warrants have been retroactively adjusted in these consolidated financial statements for all periods presented to reflect the 1-for-19 Reverse Stock Split. Numbers of shares of the Company’s preferred stock were not affected by the Reverse Stock Split; however, the conversion ratios have been adjusted to reflect the Reverse Stock Split.
