Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	13. COMMITMENTS AND CONTINGENCIES Commitments During the six months ended April 30, 2025, there were no material changes to the purchase commitments as reported in our Annual Report on Form 10-K for the fiscal year ended October 31, 2024. Contingencies On January 1, 2022, Centripetal Networks filed a lawsuit in Federal District Court in Virginia, alleging that certain Keysight products infringe certain of Centripetal’s patents. In addition, in February 2022 Centripetal filed complaints in Germany alleging infringement of certain of Centripetal’s German patents, and in April 2022 Centripetal filed a complaint with the International Trade Commission (“ITC”) requesting that they investigate whether Keysight violated Section 337 of the Tariff Act (“Section 337”) and should be enjoined from importing certain products that are manufactured outside of the U.S. and which are alleged to infringe Centripetal patents. On December 5, 2023, the ITC issued its Notice of Determination that Keysight did not unfairly import products in violation of Section 337 and the investigation was terminated. Centripetal has appealed this determination. On August 21, 2024, Keysight was served in Germany with a complaint filed in the Unified Patent Court alleging that certain Keysight products sold in Germany, France, Italy and the Netherlands infringe a European Centripetal patent. We deny the allegations and are aggressively defending each case. On June 14, 2019, the U.S. Treasury issued final regulations relating to GILTI under the tax regulations. The tax regulations contained language which disallowed GILTI tax deductions for intangible asset amortization resulting from the Singapore restructuring completed in 2018. During the third quarter of fiscal year 2024, we concluded, in response to recent U.S. Supreme Court decisions on a number of relevant cases, the evolving global tax landscape and other changes in circumstances, that Treasury exceeded its regulatory authority and the intangible asset amortization should be deductible. In response, we amended our U.S. federal income tax returns for the open tax years to claim the deduction and recognized the discrete benefit in the condensed consolidated financial statements. We believe the position meets the more likely than not recognition threshold. On January 23, 2025, we filed a lawsuit against the United States of America in the United States Court of Federal Claims seeking a tax refund of $107 million, or such greater amount allowed by law, plus any other amount, including interest and cost, allowed by law. We intend to vigorously defend our position. The outcome cannot be predicted with certainty. If we are ultimately unsuccessful in defending our refund claim, we will be required to reverse the benefit previously recorded, most likely resulting in a material increase in the effective tax rate and income tax liability. Although there are no matters pending that we currently believe are probable and reasonably possible of having a material impact to our business, consolidated financial position, or results of operations or cash flows, the outcome of litigation is inherently uncertain and is difficult to predict. An adverse outcome in any outstanding lawsuit or proceeding could result in significant monetary damages or injunctive relief. If adverse results are above management’s expectations or are unforeseen, management may not have accrued for the liability, which could impact our results in future periods. We are also involved in lawsuits, claims, investigations and proceedings, including, but not limited to, patent, employment, commercial and environmental matters, which arise in the ordinary course of business.
