Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. Commitments and Contingencies Purchase Commitments The Company currently has arrangements with contract manufacturers and suppliers for the manufacture of its products. Those arrangements allow the contract manufactures to procure long lead-time component inventory based upon a rolling production forecast provided by the Company. The Company is obligated to purchase long lead-time component inventory that its contract manufacturer procures in accordance with the forecast, unless the Company gives notice of order cancellation outside of applicable component lead-times. As of June 30, 2021, the Company had non-cancelable commitments to purchase $38.2 million of inventory and other services, which will be received and consumed during fiscal 2022. The Company expects to utilize its non-cancelable purchase commitments in the normal ongoing operations. Legal Proceedings The Company may from time to time be party to litigation arising in the course of its business, including, without limitation, allegations relating to commercial transactions, business relationships or intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Litigation in general, and intellectual property in particular, can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict. In accordance with applicable accounting guidance, the Company records accruals for certain of its outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred, and the amount of loss can be reasonably estimated. The Company evaluates, at least on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. When a loss contingency is not both probable and reasonably estimable, the Company does not record a loss accrual. However, if the loss (or an additional loss in excess of any prior accrual) is at least reasonably possible and material, then the Company would disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannot be made. The assessment whether a loss is probable or a reasonable possibility, and whether the loss or a range of loss is estimable, involves a series of complex judgments about future events. Even if a loss is reasonably possible, the Company may not be able to estimate a range of possible loss, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel or unsettled legal theories or a large number of parties. In such cases, there is considerable uncertainty regarding the ultimate resolution of such matters, including the amount of any possible loss, fine or penalty. Accordingly, for current proceedings, except as noted below, the Company is currently unable to estimate any reasonably possible loss or range of possible loss. However, an adverse resolution of one or more of such matters could have a material adverse effect on the Company's results of operations in a particular quarter or fiscal year.

Patent Infringement Suit On April 19, 2017, XR Communications, LLC (“XR”) (d/b/a Vivato Technologies) filed a patent infringement lawsuit against the Company in the Central District of California. The operative Second Amended Complaint asserts infringement of certain U.S. patent based on the Company’s manufacture, use, sale, offer for sale, and/or importation into the United States of certain access points and routers supporting multi-user, multiple-input, multiple-output technology. XR seeks unspecified damages, on-going royalties, pre- and post-judgment interest, and attorneys’ fees. The stay issued by the District Court in 2018 has been lifted. Orckit IP, LLC v. Extreme Networks, Inc., Extreme Networks Ireland Ltd., and Extreme Networks GmbH On February 1, 2018, Orckit IP, LLC (“Orckit”) filed a patent infringement lawsuit against the Company and its Irish and German subsidiaries in the District Court in Dusseldorf, Germany. The lawsuit alleges direct and indirect infringement of the German portion of a patent (“EP ’364”) based on the offer, distribution, use, possession and/or importation into Germany of certain network switches that equipped with the ExtremeXOS operating system. Orckit is seeking injunctive relief, accounting, and an unspecified declaration of liability for damages and costs of the lawsuit. On January 28, 2020, the Court rendered a decision in the infringement case in favor of the Company. The matter is proceeding through the appellate process. On April 23, 2019, Orckit filed an extension of the patent infringement complaint against the Company and its Irish and German subsidiaries in the District Court in Dusseldorf, Germany. With this extension, Orckit alleges infringement of the German portion of a second patent (“EP ‘077”) based on the offer, distribution, use, possession and/or importation into Germany of certain network switches that the Company no longer sells in Germany. Orckit is seeking injunctive relief, accounting and sales information, and a declaration of liability for damages as well as costs of the lawsuit. On October 13, 2020, the Court issued an infringement decision against the Company and granted to Orckit the right to enforce the judgment against the Company, which Orckit has provided notification to the Company that it will enforce the judgment. The Company has filed a request with the Court to suspend enforcement of the judgment. The matter is proceeding through the appellate process. The Company filed a nullity action related to the EP ‘364 patent on May 3, 2018, and one related to the EP ‘077 patent on October 31, 2019. Both cases were filed in the Federal Patent Court in Munich and seek to invalidate the asserted patents. Both nullity actions are proceeding. SNMP Research, Inc. and SNMP Research International, Inc. v. Broadcom Inc., Brocade Communications Systems LLC, and Extreme Networks, Inc. On October 26, 2020, SNMP Research, Inc. and SNMP Research International, Inc. (collectively, “SNMP”) filed a lawsuit against the Company in the Eastern District of Tennessee for copyright infringement, alleging that the Company was not properly licensed to use their software. SNMP is seeking actual damages and profits attributed to the infringement, as well as equitable relief. The Company has filed a motion to dismiss and a motion to transfer the case to the Northern District of California. Both motions are pending. Mala Technologies Ltd. v. Extreme Networks, Inc., Extreme Networks GmbH, and Extreme Networks Ireland Ltd. On April 15, 2021, Mala Technologies Ltd. (“Mala”) filed a patent infringement lawsuit against the Company and its Irish and German subsidiaries in the District Court in Dusseldorf, Germany. The lawsuit alleges indirect infringement of the German portion of a patent based on the offer and sale in Germany of certain network switches equipped with the ExtremeXOS operating system. Mala is seeking injunctive relief, accounting, and an unspecified declaration of liability for damages and costs of the lawsuit. Indemnification Obligations Subject to certain limitations, the Company may be obligated to indemnify its current and former directors, officers and employees. These obligations arise under the terms of its certificate of incorporation, its bylaws, applicable contracts, and applicable law. The obligation to indemnify, where applicable, generally means that the Company is required to pay or reimburse, and in certain circumstances the Company has paid or reimbursed, the individuals' reasonable legal expenses and possibly damages and other liabilities incurred in connection with certain legal matters. The Company also procures Directors and Officers liability insurance to help cover its defense and/or indemnification costs, although its ability to recover such costs through insurance is uncertain. While it is not possible to estimate the maximum potential amount that could be owed under these governing documents and agreements due to the Company’s limited history with prior indemnification claims, indemnification (including defense) costs could, in the future, have a material adverse effect on the Company’s consolidated financial position, results of operations and cash flows.
