On December 11, 2019, the Patent Trial and Appeal Board (PTAB) designated three decisions as “informative”.

These decisions are:
Hulu, LLC v. Sound View Innovations, LLC, Case IPR2018-00582 (Aug. 5, 2019)
Johns Manville Corp. v. Knauf Insulation, Inc., Case IPR2018-00827 (Oct. 16, 2018)
Ex parte Linden, 2018-003323 (Apr. 1, 2019)

Whereas a “precedential” decision establishes binding authority, an “informative” decision provides norms on recurring issues, guidance on issues of first impression, guidance on rules and practices, and guidance on issues that may develop.
