Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 8 - COMMITMENTS AND CONTINGENCIES Government Grants: Microbot Israel has received grants from the Israeli Innovation Authority (“IIA”) for participation in research and development since 2013 through 2020, totaling approximately $1,500. In return, the Company is obligated to pay royalties amounting to 3%-3.5% of its future sales from commercialization of the funded research and development, up to the amount of the grants received. The payment of royalties with respect to the repayment of the grants is contingent upon the successful completion of the Company’s research and development programs and generating sales. The Company has no obligation to repay these grants, if the project fails, is unsuccessful or aborted or if no sales are generated. The financial risk is assumed completely by the Government of Israel. TRDF Agreement: Microbot Israel signed an agreement with the Technion Research and Development Foundation (“TRDF”) in June 2012 by which TRDF transferred to Microbot Israel a global, exclusive, royalty-bearing license. As partial consideration for the license, Microbot Israel shall pay TRDF royalties on net sales (between 1.5%-3%) and on sublicense income as detailed in the agreement. Agreement with CardioSert Ltd.: On January 4, 2018, Microbot Israel entered into an agreement with CardioSert Ltd. (“CardioSert”) to acquire certain patent-protected technology owned by CardioSert (the “Technology”). Pursuant to the Agreement, Microbot Israel made an initial payment of $50 to CardioSert and had 90-days to elect to complete the acquisition. At the end of the 90-day period, at Microbot Israel’s sole option, CardioSert shall assign and transfer the Technology to Microbot Israel and Microbot Israel shall pay to CardioSert additional amounts and securities as determined in the agreement. On May 25, 2018, Microbot delivered an Exercise Notice to CardioSert Ltd., notifying it that Microbot elected to exercise the option to acquire the Technology owned by CardioSert and therefore made an additional cash payment of $250 and 6,738 shares of common stock estimated at $74. The agreement may be terminated by Microbot Israel at any time for convenience upon 90-days’ notice. The agreement may be terminated by CardioSert in case the first commercial sale does not occur by the third anniversary of the date of signing of the agreement except if Microbot Israel has invested more than $2,000 in certain development stages, or the first commercial sale does not occur within 50 months. In each of the above termination events, or in case of breach by Microbot Israel, CardioSert shall have the right to buy back the Technology from Microbot Israel for $1.00, upon 60 days prior written notice, but only 1 year after such termination. Additionally, the agreement may be terminated by either party upon breach of the other (subject to cure). CardioSert agreed to assist Microbot Israel in the development of the Technology for a minimum of one year, for a monthly consultation fee of NIS 40,000 (or approximately US$12.40, based on an exchange rate of NIS3.215 to the dollar) covering up to 60 consulting hours per month. Litigation: Litigation Resulting from 2017 Financing The Company lost its appeal of an adverse judgment in the lawsuit captioned Sabby Healthcare Master Fund Ltd. and Sabby Volatility Warrant Master Fund Ltd., Plaintiffs, against Microbot Medical Inc., Defendant, in the Supreme Court of the State of New York, County of New York (Index No. 654581/2017). As a result, the Securities Purchase Agreement (the “SPA”) related to the Company’s June 8, 2017 equity financing (the “Financing”) was rescinded as it related to Sabby Healthcare Master Fund Ltd. and Sabby Volatility Warrant Master Fund Ltd. (“Sabby”), and the Company paid approximately $3,700 to Sabby in return for the 83,333 shares of common stock Sabby purchased pursuant to the SPA. Soon after, the Company was named as the defendant in a lawsuit captioned Empery Asset Master Ltd., Empery Tax Efficient, LP, Empery Tax Efficient II, LP, Hudson Bay Master Fund Ltd., Plaintiffs, against Microbot Medical Inc., Defendant, in the Supreme Court of the State of New York, County of New York (the “Court”) (Index No. 651182/2020). The complaint alleges, among other things, that the Company breached multiple representations and warranties contained in the SPA, of which the Plaintiffs participated, and fraudulently induced Plaintiffs into signing the SPA. The complaint seeks rescission of the SPA and return of the Plaintiffs’ $6,750 purchase price with respect to the Financing. The Company filed a Motion to Dismiss on March 16, 2020, which was denied in February 2021. The Company’s management is unable to assess the likelihood that it would be successful in any trial with respect to the SPA or the Financing, having previously lost the Sabby lawsuit. Accordingly, no assurance can be given that if the Company goes to trial and ultimately loses, or if the Company decides to settle at any time, such an adverse outcome would not be material to the Company’s consolidated financial position. Alliance Litigation On April 28, 2019, the Company brought an action against Alliance Investment Management, Ltd. (“Alliance”), later amended to include Joseph Mona (“Mona”) as a defendant, in the Southern District of New York under Section 16(b) of the Securities Exchange Act of 1934, 15 U.S.C. 78p(b), to compel Alliance and Mona to disgorge short swing profits realized from purchases and sales of the Company’s securities within a period of less than six months. The case is Microbot Medical Inc. v. Alliance Investment Management, Ltd., No. 19-cv-3782-GBD (SDNY). The amount of profits was estimated in the complaint to be approximately $468. On October 28, 2019, Alliance filed a motion for summary judgment requesting that the Court dismiss the claims against Alliance. On February 4, 2020, Mona answered the 16(b) claim the Company asserted against him by claiming various equitable defenses, and filed a counterclaim against the Company under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, claiming a net loss on trading the Company’s stock of approximately $151. On March 6, 2020, the Company filed a motion for judgment on the pleadings with respect to the Company’s 16(b) claim against Mona, together with a motion to dismiss Mona’s 10(b) counterclaim. On September 17, 2020, the Court issued a Memorandum Decision & Order that, among other things, granted Alliance’s summary judgment motion. The Company’s Section 16(b) claim against Mona remained pending following the Court’s dismissal of the Section 16(b) claim against Alliance. On December 18, 2020, the Magistrate Judge issued a Report & Recommendation, which recommended that: (i) judgment of $484,614.30 be entered in the Company’s favor on its Section 16(b) claim against Mona; and (ii) Mona’s Section 10(b) claim be dismissed with prejudice (except as to allegations regarding statements purportedly made by employees of Integra Consulting, an outside investor relations firm, which the Magistrate recommended be dismissed without prejudice). On January 4, 2021, Mona filed Objections to the Magistrate’s Report & Recommendation, which is pending.
