Work Highlights

High-Stakes Individual Representations

Confidential Dispute Between Angel Investors and Blockchain Startup.

Represented a group of high-profile Silicon Valley angel investors and preferred shareholders in a cryptocurrency and blockchain startup who claimed rights to share in a distribution of tokens under the corporate certificate and their stock purchase agreement. The dispute arose shortly before the company’s highly anticipated token launch, when the investors discovered that the company founder had distributed millions of tokens to himself and his employees without sharing them with his shareholders. Morrissey was lead counsel in developing a litigation and settlement strategy that resulted in a confidential settlement worth hundreds of millions of dollars. This strategy quickly resolved the dispute and enabled clients to avoid litigation that could have disrupted the token launch, thereby protecting the value of their substantial investments.

Lamar v. Beats Electronics, Dr. Dre. and Jimmy Iovine.

Morrissey was co-lead counsel in a breach of contract case on behalf of entrepreneur Steven Lamar and his company, Jibe Audio, involving a claim for royalties on the iconic Beats headphones products. In 2018, Morrissey’s trial team won a jury verdict that confirmed Lamar’s right to royalties on Beats headphones and would result in a judgment worth more than $50 million for past damages, interest, ongoing royalties, and attorneys’ fees. The case settled for a confidential amount.

Peak Hosting v. Machine Zone

Morrissey was co-lead counsel to Peak Hosting in its breach-of-contract and business tort lawsuit against Machine Zone, Inc.—a Silicon Valley giant and purveyor of two of the most popular mobile games, “Mobile Strike” and “Game of War.” The matter was settled on confidential terms.

Hussein v. Quality Systems.

Morrissey represents an Egyptian investor in shareholder litigation in Orange County, California Superior Court. In 2017, Morrissey won a bench trial of the defendants’ cross-claim, and in 2019 Morrissey and his team won an appeal that reinstated his client’s fraud claims. The case is now back in the trial court and will be set for trial. Morrissey previously represented the same client in the successful trial of a FINRA arbitration against a leading investment bank in New York.

Casey v. Simmons

In 2009 Morrissey won a $178.7 million jury verdict, which included $145 million in punitive damages. The case involved breach of contract and breach of fiduciary duty case on behalf of the three entrepreneurs who owned an environmental cleanup company. The case settled for a confidential amount while on appeal.

Masimo v. Tyco.

Morrissey first won a $420 million jury verdict (after trebling) in an antitrust case based on Tyco Healthcare Group’s monopolization of the market for pulse oximetry products. After the trial court upheld the liability findings and ordered a new trial on damages, Morrissey and his team then won again, with the trial court entering a judgment for $43.5 million in damages (after trebling), plus attorneys’ fees, in June 2007. Masimo ultimately was awarded $58.9 million after another win affirming the judgment in the U.S. Court of Appeals for the Ninth Circuit.

PSI v. IBM.

Morrissey was one of the lead lawyers responsible for the representation of startup mainframe computer manufacturer Platform Solutions, Inc. in prosecuting multi-hundred million dollar antitrust claims against IBM, and in defending PSI against patent infringement, copyright, and trade secrets claims brought by PSI, in the U.S. District Court for the Southern District of New York. Morrissey also coordinated PSI’s prosecution of competition claims against IBM in the EU. In July 2008, the case settled on confidential terms in June 2008; as part of the settlement, PSI was acquired by IBM.

Ravikant v. Tolia.

Morrissey represented 51 former shareholders and early employees of Epinions, Inc. in groundbreaking litigation involving the fiduciary duties of venture capitalists and venture capital firms when serving on the boards of portfolio companies, the duties of founders to one another, and the valuation of common stock in startup acquisitions. The case was successfully settled on confidential terms.

HIGH PROFILE CLASS ACTIONS

Ferrick v. Spotify.

Secure a $43.45 million cash fund (final amount after fees and expenses to be determined) and an agreement to pay future royalties estimated to be worth more than $65 million to settle a class-action lawsuit with Spotify brought on behalf of music copyright owners. The suit alleged that Spotify made music available online without securing mechanical rights from the tracks’ composers.

White v. NCAA.

Morrissey was one of the lead lawyers responsible for the pioneering litigation and settlement in this antitrust class action in the Central District of California that paved the way for subsequent antitrust challenges to NCAA restrictions on the rights of student athletes. The parties reached a settlement that was approved by the Court in August 2008 where the NCAA made $218 million over five years available to provide additional benefits for student-athletes, revised its rules to allow member schools to provide student athletes with comprehensive year-round health insurance, and created a $10 million fund to cover educational and professional development expenses incurred by members of the class.

DEFENSE-SIDE WINS

FSG Services LLC. v. Flutter Entertainment.

Secured a favorable award for Flutter Entertainment when an arbitrator in New York nearly doubled the exercise price its opponent, FOX Corporation, sought for its option to acquire 18.6% of Flutter’s portfolio company, FanDuel Group. This high stakes, high profile arbitration resulted from FOX’s assertion that it should be entitled to the same price Flutter paid for its share of FanDuel two years before the arbitration took place – $2.1 billion, with an implied company valuation of $11.2 billion. The arbitrator, however, found that FOX’s payment must be based on a substantially higher FanDuel valuation of $20 billion it was hoping for, plus an additional 5% interest per year. At the time of the decision, this equated to a valuation for FanDuel of $22 billion and an option exercise price of $4.1 billion for FOX — nearly twice the amount that FOX argued it should be required to pay. The arbitrator also rejected FOX’s claim that Flutter had not provided commercially reasonable resources to the Fox Bet business.
