The U.S. Supreme Court issued an opinion on April 5, 2021 that held "Google’s copying of the Java SE API, which included only those lines of code that were needed to allow programmers to put their accrued talents to work in a new and transformative program, was a fair use of that material as a matter of law." Google's Android operating system relies on the copied code and Oracle had sought $9 billion in damages.
A recent case between two medical device companies raised the question of the constitutionality of the method in which Patent Trial and Appeal Board (PTAB) judges are appointed. PTAB judges are administrative patent judges who examine patents whose validity is questioned and hear appeals from patentees whose patent applications have been rejected. More specifically, PTAB judges hear appeals from adverse examiner decisions in patent applications and reexamination proceedings, conduct America Invents Act (AIA) trial proceedings, and hear interference proceedings. The PTAB is an administrative court run by the USPTO and was created by Congress as part of the AIA.
