James Grimmelmann reports that Michael Boni told US District Court Judge Denny Chin at the 7/19/11 status conference that the parties involved in the Google Books lawsuit "have been aiming for an opt-in settlement." The next status conference will occur on 9/15/11.
Here's an excerpt from Grimmelmann's "GBS Status Conference: Opt-in Settlement in the Works?" post:
What that might mean is not obvious. It could mean an actual opt-in settlement, one that binds only class members who send in claim forms. It could mean a settlement in which Google commits to an open-ended offer to all class members. It could mean a narrower, scanning-and-searching-only settlement, so that copyright owners can "opt in" to book sales by striking their own individual deals with Google.
