The USPTO’s online classification search system has a new feature that will make browsing classification schedules much easier. Users can now use an “Outline” feature to collapse any schedule from its normal full display to just its mainline through level five indents. Users can also click on -/+ symbols on the left side of the schedule to collapse or expand individual sections.
