Activision Blizzard is set to appeal the Delaware Supreme Court's decision to halt its $8.2 billion share purchase from controlling corporation Vivendi, Reuters reports.

Activision aims to buy itself back from Vivendi through share purchases spearheaded by the company itself and an investor group led by Activision CEO Bobby Kotick. The combined share purchase would reduce Vivendi's current 61 percent stake in Activision to 12 percent, reestablishing Activision as an independent company.

Purchase plans were halted last week by the Delaware Supreme Court, citing recent lawsuits over Activision's failure to put the purchase to shareholder vote. Activision will begin its appeal to overturn the decision on October 10.
