Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES COMMITMENTS Our commitments include an estimated amount of approximately $845 million relating to the Company’s open purchase orders and contractual obligations that occur in the ordinary course of business, including commitments with contract manufacturers and suppliers for which the Company has not received the goods or services, commitments for capital expenditures and construction-related activities for which the Company has not received the services, and acquisition and licensing of intellectual property. Although open purchase orders are considered enforceable and legally binding, the terms generally allow the Company the option to cancel, reschedule, and adjust its requirements based on its business needs prior to the delivery of goods or performance of services. In addition to the above, the Company has committed to make certain future milestone payments to third parties as part of licensing, collaboration, and development arrangements. Payments under these arrangements generally become due and payable only upon the achievement of certain specified developmental, regulatory, and/or commercial milestones. For instances in which the achievement of these milestones is neither probable nor reasonably estimable, such contingencies are not included in the estimated amount. CONTINGENCIES From time to time, the Company is involved in a variety of claims, lawsuits, investigations, and proceedings relating to securities laws, product liability, intellectual property, insurance, contract disputes, employment, and other matters. Certain of these lawsuits and claims are described in further detail below. It is not possible to predict what the outcome of these matters will be, and the Company cannot guarantee that any resolution will be reached on commercially reasonable terms, if at all. A liability and related charge to earnings are recorded in the Consolidated Financial Statements for legal contingencies when the loss is considered probable and the amount can be reasonably estimated. The assessment is re-evaluated each accounting period and is based on all available information, including the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to each case. Nevertheless, it is possible that additional future legal costs (including settlements, judgments, legal fees, and other related defense costs) could have a material adverse effect on the Company’s business, financial position, or future results of operations. During the years ended December 31, 2019, 2018, and 2017, the Company recorded pre-tax litigation charges of $0.5 million, $45.2 million, and $16.3 million, respectively, related to the securities class action lawsuits and the tolled product liability claims described below. A total of $4.2 million and $53.0 million associated with these matters were included in other accrued liabilities in the accompanying Consolidated Balance Sheets as of December 31, 2019, and 2018, respectively. Purported Shareholder Class Action Lawsuits filed April 26, 2013, and May 24, 2013 On April 26, 2013, a purported class action lawsuit entitled Abrams v. Intuitive Surgical, et al., No. 5-13-cv-1920, was filed against a number of the Company’s current and former officers and directors in the U.S. District Court for the Northern District of California. The case has since been retitled In re Intuitive Surgical Securities Litigation, No. 5:13-cv-1920. The plaintiffs sought damages on behalf of a putative class of persons who purchased or otherwise acquired the Company’s common stock between February 6, 2012, and July 18, 2013. The amended complaint alleged that the defendants violated federal securities laws by allegedly making false and misleading statements and omitting certain material facts in certain public statements and in the Company’s filings with the SEC. On June 11, 2018, the Company reached an agreement in principle to enter into a settlement agreement, which stipulates a payment of $42.5 million by the Company. The court granted preliminary approval on October 4, 2018, and on December 20, 2018, the court granted final approval. During the year ended December 31, 2018, the Company recorded a pre-tax charge of $42.5 million for this matter. In connection with the settlement, the Company deposited $42.5 million into an escrow account established for disbursements, which was recorded in prepaids and other current assets in the accompanying Consolidated Balance Sheets as of December 31, 2018. The appeals period expired on January 21, 2019, the payment was made in 2019, and the matter has been concluded. Product Liability Litigation The Company is currently named as a defendant in a number of individual product liability lawsuits filed in various state and federal courts. The plaintiffs generally allege that they or a family member underwent surgical procedures that utilized the da Vinci Surgical System and sustained a variety of personal injuries and, in some cases, death as a result of such surgery. Several of the filed cases have trial dates in the next 12 months. The cases raise a variety of allegations including, to varying degrees, that plaintiffs’ injuries resulted from purported defects in the da Vinci Surgical System and/or failure on the Company’s part to provide adequate training resources to the healthcare professionals who performed plaintiffs’ surgeries. The cases further allege that the Company failed to adequately disclose and/or misrepresented the potential risks and/or benefits of the da Vinci Surgical System. Plaintiffs also assert a variety of causes of action, including, for example, strict liability based on purported design defects, negligence, fraud, breach of express and implied warranties, unjust enrichment, and loss of consortium. Plaintiffs seek recovery for alleged personal injuries and, in many cases, punitive damages. In addition to the filed cases, the Company previously received a substantial number of claims relating to alleged complications from surgeries performed with certain versions of Monopolar Curved Scissor (“MCS”) instruments, which included an MCS tip cover accessory that was the subject of a market withdrawal in 2012 and MCS instruments that were the subject of a recall in 2013. In an effort to avoid the expense and distraction of defending multiple lawsuits, the Company entered into tolling agreements to pause the applicable statutes of limitations for many of these claims and engaged in confidential mediation efforts. As of December 31, 2019, the majority of the “tolled claims” have either been resolved or the matters have been filed. During the years ended December 31, 2019, 2018, and 2017, the Company recorded $0.5 million, $2.7 million, and $16.3 million, respectively, of pre-tax charges to reflect the estimated cost of settling a number of the product liability claims covered by the tolling agreements. As of December 31, 2019, and 2018, a total of $4.2 million and $10.5 million, respectively, were included in other accrued liabilities in the accompanying Consolidated Balance Sheets related to the tolled product liability claims. The Company’s estimate of the anticipated cost of resolving the pending lawsuits and claims is based on negotiations with attorneys for the plaintiffs/claimants. The final outcome of the pending lawsuits and claims, and others that might arise, is dependent on many variables that are difficult to predict and the ultimate cost associated with these product liability lawsuits and claims may be materially different than the amount of the current estimate and accruals and could have a material adverse effect on the Company’s business, financial position, and future results of operations. Although there is a reasonable possibility that a loss in excess of the amount recognized exists, the Company is unable to estimate the possible loss or range of loss in excess of the amount recognized at this time. Patent Litigation On June 30, 2017, Ethicon LLC, Ethicon Endo-Surgery, Inc., and Ethicon US LLC (collectively, “Ethicon”) filed a complaint for patent infringement against the Company in the U.S. District Court for the District of Delaware. The complaint, which was served on the Company on July 12, 2017, alleges that the Company’s EndoWrist Stapler instruments infringe several of Ethicon’s patents. Ethicon asserts infringement of U.S. Patent Nos. 9,585,658, 8,479,969, 9,113,874, 8,998,058, 8,991,677, 9,084,601, and 8,616,431. A claim construction hearing occurred on October 1, 2018, and the court issued a scheduling order on December 28, 2018. On March 20, 2019, the court granted the Company's Motion to Stay pending an Inter Parties Review to be held at the Patent Trademark and Appeals Board to review patentability of six of the seven patents noted above and vacated the trial date. On August 1, 2019, the court granted the parties' joint stipulation to modify the stay in light of Ethicon's U.S. International Trade Commission ("USITC") complaint against Intuitive involving U.S. Patent Nos. 8,479,969 and 9,113,874, discussed below. On August 27, 2018, Ethicon filed a second complaint for patent infringement against the Company in the U.S. District Court for the District of Delaware. The complaint alleges that the Company’s SureForm 60 Staplers infringe five of Ethicon’s patents. Ethicon asserts infringement of the U.S. Patent Nos. 9,884,369, 7,490,749, 8,602,288, 8,602,287, and 9,326,770. The Company filed an answer denying all claims. On March 19, 2019, Ethicon filed a Motion for Leave to File a First Amended Complaint, removing allegations related to U.S. Patent No. 9,326,770 and adding allegations related to U.S. Patent Nos. 9,844,379 and 8,479,969. On July 17, 2019, the court entered an order denying the amendment, without prejudice, and granting the parties' joint stipulation to stay the case in its entirety in light of the USITC investigation involving U.S. Patent Nos. 9,844,369 and 7,490,749, discussed below. On May 30, 2019, Ethicon filed a complaint with the USITC, asserting infringement of U.S. Patent Nos. 9,884,369, 7,490,749, 9,844,379, 9,113,874, and 8,479,969. On June 28, 2019, the USITC voted to institute an investigation (No. 337-TA-1167) with respect to claims in this complaint. The accused products include the Company's EndoWrist 30, EndoWrist 45, SureForm 45, and SureForm 60 Staplers, as well as the stapler reload cartridges. The evidentiary hearing is set for April 20-24, 2020, and the target for completion of the investigation is December 7, 2020. An unfavorable ruling by the USITC could have an adverse effect on our results of operations, including a prohibition on importing the accused products into the U.S. or necessitating workarounds that may limit certain features of our products. Based on currently available information, the Company is unable to make a reasonable estimate of losses or range of losses, if any, arising from these matters. Commercial Litigation On February 27, 2019, Restore Robotics LLC and Restore Robotics Repair LLC ("Restore") filed a Complaint alleging anti-trust claims against the Company. On May 13, 2019, Restore filed an Amended Complaint alleging anti-trust claims relating to the da Vinci Surgical System and EndoWrist service, maintenance, and repair processes. On September 16, 2019, the Court partially granted and partially denied the Company's Motion to Dismiss the Amended Complaint. On September 30, 2019, the Company filed an Answer denying the anti-trust allegations and a Counterclaim against Restore. The Company filed Amended Counterclaims after the Court partially granted and partially denied Restore's Motion to Dismiss the Counterclaim. The Amended Counterclaims allege that Restore violated the Federal Lanham Act, the Federal Computer Fraud and Abuse Act, and Florida's Deceptive and Unfair Trade Practices Act and that Restore is also liable to the Company for Unfair Competition and Tortious Interference with Contract. On January 7, 2020, the Court denied Restore's Motion to Dismiss the Amended Counterclaims. In its initial scheduling order, the Court stated that it anticipate trial in this case to occur on or before February 2022. Based on currently available information, the Company is unable to make a reasonable estimate of loss or range of losses, if any, arising from these matters.
