Microsoft Accuses InterDigital of Antitrust Behavior
Microsoft has filed an antitrust lawsuit against InterDigital, a patent-licensing firm, for charging exorbitant rates to license standard-essential patents. The two companies have been embroiled in patent litigation for years. Earlier this year, Microsoft was found by the U.S. ITC to be violating two wireless patents owned by InterDigital. The judge in that case recommended Microsoft's handsets be banned from import. Microsoft says InterDigital is using this potential import ban as a bargaining chip to jack up licensing rates. Patents deemed essential must be licensed at fair, reasonable, and non-discriminatory rates. Microsoft charges that InterDigital's "abusive licensing practices" violate federal antitrust law. InterDigital has taken ZTE, Nokia, Huawei, Samsung, and others to court over patents with mixed success.

Microsoft Loses Patent Case to InterDigital
The International Trade Commission today ruled Microsoft improperly used two InterDigital wireless patents without permission. The ruling judge said "it would not be against the public interest to ban the Microsoft [phones] from import into the United States."

Motorola Owes Microsoft $14.5 Million Over Patent Spat
An appeals court has sided with Microsoft and upheld a 2013 verdict that says Motorola has to pay Microsoft for refusing to license standard-essential patents at fair, reasonable, and non-discriminatory rates. This particular case began in 2010, when Microsoft sued Motorola for failing to pay it patent-licensing fees for technology found in Motorola's Android smartphones.
