Since joining the firm at its inception in 1997, Bill Isaacson’s main practice areas have included complex commercial litigation, including trial work and arbitration.  

Global Competition Review writes that "Arguably no antitrust lawyer in recent memory has had as much success for both plaintiffs and defendants as Boies Schiller partner Bill Isaacson.”  Mr. Isaacson is a 2015 American Lawyer Litigator of the Year (click here), a three time winner of The AmLaw Litigator of the Week (click here) (click here) (click here), and has been listed as one of the 500 leading lawyers in the U.S. by the publication Lawdragon  (click here), and a Competition MVP and Titan of the Plaintiff Bar by Law360 (click here) (click here)(click here), and a Litigator of the Week by Global Competition Review (click here). Legal describes Mr. Isaacson as a “leader” at BSF “with many successes to his credit.” (click here).  In 2015, following an over 3 week jury trial in the District of Nevada for Oracle Corporation, Isaacson, together with BSF co-counsel Karen Dunn,  won a $50 million verdict for software copyright infringement and state law violations.  In 2014, in O’Bannon v. NCAA, he won significant attention for his cross-examinations of NCAA witnesses and in obtaining a historic victory for college athletes. (click here). In 2014, Mr. Isaacson also served as co-lead trial counsel, again with Ms. Dunn, in a high profile antitrust class action in the portable music industry, winning a complete defense verdict.

In other examples, Mr. Isaacson has acted as trial counsel for plaintiffs in Animal Science Products v. Mitsui & Co. (D.D.C.), an international cartel case, resulting in a jury verdict for the class of $49.5 million (before trebling) (National Law Journal, August 4, 2003 p. 13) and In re Scrap Metal Antitrust Litigation (N.D. Ohio) winning a jury verdict of $11.5 million before trebling.  Mr. Isaacson also has acted as a Steering Committee Member in In re Vitamins Antitrust Litigation in which the firm uncovered an international conspiracy and represented purchasers of a range of vitamins in pursuing price fixing and market allocation claims ("Not Your Father's Class Action," National Law Journal, June 7, 1999, p.A5), resulting in an over $1 billion in settlements.    Among other cases, Mr. Isaacson represents Firm clients in In re TFT-LCD Antitrust Litigation and In re Cathode Ray Tube Antitrust Litigation andis currently colead counsel for the direct purchaser class in In re Municipal Derivatives Antitrust Litigation (S.D.N.Y.) ($200 millin in settlements) and In re Polyurethane Foam Antitrust Litigation (N.D.Ohio). ($430 million settlements).

In the field of arbitration, Legal 500 (click here) describes Isaacson as having a “brilliant knowledge of international arbitration.” For example, Mr. Isaacson has acted as lead counsel in proceedings in the Southern District of Texas and the Fifth Circuit to enforce an international arbitration award under the New York Convention resulting in a $261 million judgment which was affirmed on appeal.  Karaha Bodas Co., L.L.C. v.

AOL (AAA Arbitration/Washington D.C.) asserting claims for breach of contract arising out of an internet distribution agreement.   Following a two week trial and before a final award, the parties entered a settlement agreement restructuring the distribution agreement and terminating a $57 million payment due from Homestore and reducing future payments by $9 million per quarter (click here).  

Mr. Isaacson also has acted as counsel in Worldspan v. Abacus (ICC Arbitration / London) (following a three week trial in 1999, a 300 page Award in August 2000 found for Claimant Worldspan on claims for fraud, breach of fiduciary duty, breach of contract, misappropriation of confidential information and conspiracy and awarded $39.5 million); Kuwait Oil Company & UK Oil Company v.  UK Oil Company et al. (LCIA Arbitration/London) (following an arbitration in London and Kuwait, an arbitration award in December 2000 affirmed Claimant's contractual equity interest in billion barrel oil fields at issue, and awarded fees and costs to Claimants); Shandling v. Grey (representing comedian Garry Shandling against his former manager for breach of fiduciary duty through to settlement following a decision denying a motion for summary adjudication, see "Shandling Claims Get New Life in a Stunning Reversal," Variety June 23, 1999, p. 1).
