The last review in Trends and Events on the topic of patent harmonisation (cf, Trends and Events, 2015) looked forward to a stepping up of work on SPLH from the B+ Sub-Group and from the Industry Trilateral, all working under the remit of the Group B+.

Through 2017 and to date in 2018, the Industry Trilateral (IT3) has met numerous times, and with increasing frequency, both in person and via WebEx calls with the aim of trying to reach agreement on a possible SPLH package that could be acceptable to users.
