A group of investors killed a deal to buy the Weinstein Company for the second time. According to The Wall Street Journal:

Weinstein Co. once again appeared headed toward a bankruptcy filing Tuesday after its would-be buyer said it was withdrawing from a deal.

A buyers’ group organized by investor Ron Burkle and publicly led by businesswoman Maria Contreras-Sweet said it called off a deal for most of the beleaguered film and TV studio’s assets less than a week after saying it would buy them by assuming $225 million of debt. The group also planned to invest $275 million to relaunch Weinstein Co. with a new name.

“We have received disappointing information about the viability of completing this transaction,” Ms. Contreras-Sweet said in a statement. A person familiar with the group said it had found about $65 million of additional liabilities.

In its 117-page court filing in U.S. federal court in Los Angeles, BlackBerry says the defendants “created mobile messaging applications that co-opt BlackBerry’s innovations, using a number of the innovative security, user interface, and functionality enhancing features that made BlackBerry’s products such a critical and commercial success in the first place.”

The suit alleges the defendants improperly used BlackBerry’s intellectual property that streamlines notifications to “prevent users from being inundated,” as well as the display of time stamps on messages and the tagging of friends and family in social-media photographs.
