Commitments and Contingencies	Commitments and Contingencies Legal Matters Hytera Litigation On March 14, 2017, the Company filed a complaint in the U.S. District Court for the Northern District of Illinois (the "Court") against Hytera Communications Corporation Limited of Shenzhen, China; Hytera America, Inc.; and Hytera Communications America (West), Inc. (collectively, "Hytera"), alleging trade secret theft and copyright infringement and seeking, among other things, injunctive relief, compensatory damages, and punitive damages. On February 14, 2020, the Company announced that a jury in the Court decided in the Company's favor in its trade secret theft and copyright infringement case. In connection with this verdict, the jury awarded the Company $345.8 million in compensatory damages and $418.8 million in punitive damages, for a total of $764.6 million. The Court denied Hytera’s motion for a new trial on October 20, 2020. On December 17, 2020, the Court denied the Company’s motion for a permanent injunction, finding instead that Hytera must pay the Company a forward-looking reasonable royalty on products that use the Company’s stolen trade secrets. As the parties were unable to agree on a reasonable royalty rate, the Court entered an order favorable to the Company on December 15, 2021, and, consistent with the Company's requests, set royalty rates for Hytera's sale of relevant products from July 1, 2019 forward. The Court also ordered the parties to jointly file by February 22, 2022, a proposed royalty agreement for the Court's review and approval. Because the parties could not concur on the royalty agreement, they each filed supporting papers for their proposed draft agreements, and on April 12, 2022, the Court issued a ruling generally favorable to the Company on the critical aspects of the royalty agreement. On April 19, 2022, the parties filed an agreed royalty agreement that incorporates the findings of the Court's ruling. In response to the Court's decision to award the Company $764.6 million in compensatory and punitive damages, Hytera motioned for certain equitable relief. On January 8, 2021, the Court granted Hytera’s motion for certain equitable relief and reduced the $764.6 million judgment award to $543.7 million. That same day, the Court also granted the Company’s motion for pre-judgment interest. On August 10, 2021, the Court ruled that Hytera must pay the Company $51.1 million in pre-judgment interest and $2.6 million in costs. On March 25, 2021, the Court entered rulings favorable to the Company with respect to several of the Company's post-trial motions, including the Company's motion for attorneys' fees and its motion to require Hytera to turn over certain assets in satisfaction of the Company’s judgment award. On September 7, 2021, Hytera filed a notice of appeal of the Court’s judgment with the U.S. Court of Appeals for the Seventh Circuit (the "Court of Appeals"). The parties have briefed a jurisdictional issue raised by the Court of Appeals in response to Hytera's notice of appeal and await the Court's determination. On September 29, 2021, the Company filed two additional motions with the Court, requesting the Court to reconsider its order denying the Company’s request for an injunction, and requesting that the Court enforce its ruling requiring Hytera to turn over certain assets in satisfaction of the Company's judgment award, or, in the alternative, hold Hytera in contempt. On October 15, 2021, the Court granted the Company’s request for $34.2 million in attorneys’ fees against Hytera. Hytera Bankruptcy Proceedings Separate from the Company's litigation with Hytera, on May 27, 2020, Hytera America, Inc. and Hytera Communications America (West), Inc. each filed for Chapter 11 bankruptcy protection in the U.S. Bankruptcy Court for the Central District of California (the “Bankruptcy Court”). The Company filed motions in the Bankruptcy Court to dismiss the bankruptcy proceedings in July 2020. On January 22, 2021, the Bankruptcy Court entered an agreed order, allowing a partial sale of Hytera's U.S. assets in the bankruptcy proceedings. The proposed sale does not include Hytera inventory accused of including the Company’s intellectual property. On February 11, 2022, the Court entered an order to confirm the liquidation plan for the two Hytera entities and the distributions were made on February 25, 2022 to the creditors, including a distribution of $13 million to the Company. The gain was recorded to Other charges (income) in the Company's Condensed Consolidated Statements of Operations.
