• Activision countersues ‘Modern Warfare’ execs

SANTA MONICA, Calif. — Two former studio heads overseeing last year’s blockbuster video game "Modern Warfare 2" were fired for insubordination and trying to poach key employees from Activision, the gaming giant alleged in court filings.

Activision on Thursday countersued former Infinity Ward executives Jason West and Vince Zampella, who sued Activision for more than $36 million in March. West and Zampella’s lawsuit claimed they were fired so Activision could avoid paying them hefty royalties for their work on the popular franchise.

Activision’s filing seeks to show the firing was justified and claims the men met with a key gaming rival, which it says was one of several violations of their employment contract.

Infinity Ward is the studio behind last fall’s record-breaking release, "Call of Duty: Modern Warfare 2," and other games. "Modern Warfare 2" was No. 1 last year and has become one of the best-selling video games of all time.

The breach of contract suit claims West and Zampella held up development on other "Call of Duty" games to try to gain more money. The company is seeking to withhold additional payments to the men, who they claim also kept bonuses from Infinity Ward employees.

The men "morphed from valued, responsible executives into insubordinate and self-serving schemers who attempted to hijack Activision’s assets for their own personal gain and whose actions threatened both the future of the Call of Duty franchise and future of Activision’s (Infinity Ward) studio," the complaint states.

West and Zampella’s attorney, Robert M. Schwartz, called the countersuit’s claims "false and outrageous."

"None of the false claims of insubordination or breach of duties had any negative affect on Activision — none," Schwartz said in a statement. "Modern Warfare 2 has been the world’s most successful video game."

The lawsuit alleges the bonuses were withheld in an attempt to try to leverage other key employees to leave Santa Monica-based Activision.

Schwartz denied that claim, calling Activision’s suit a tactic to withhold bonuses from other Infinity Ward employees.

The filing does not state by name which rival West and Zampella are accused of meeting with, but states they were flown by the rival to Northern California. Gaming giant Electronic Arts, which is Activision’s main rival and produces the competitor franchise "Medal of Honor," is based in Northern California.

The cases are filed in Santa Monica, where Activision is based. The company is majority owned by French conglomerate Vivendi SA.

• Xerox CEO Burns’ pay jumps with promotion in 2009

LOS ANGELES — Xerox Corp. CEO Ursula Burns, the first black woman to lead a Fortune 500 company, saw her pay increase 77 percent in 2009 after she was promoted from president and kept cutting costs amid an economic downturn.

Burns’ pay climbed to $9.9 million last year from $5.6 million the year before, according to an Associated Press analysis of a regulatory filing.

Burns, 51, became chief executive in July, taking over from Anne Mulcahy, who is credited with turning the company around over the past decade and plans to retire as board chair in May.

Mulcahy’s compensation fell 59 percent to $4.9 million from $12 million the previous year.

Burns’ salary rose slightly to $900,000 from $887,500 a year before. Her performance-based cash bonus more than tripled to $1.9 million from about $550,000 a year earlier.

The biggest pay boost came from the value of stock options, which grew to $6.9 million at the time they were granted from similar awards of $4 million received the previous year.

Burns also received other compensation of $200,105, including personal use of company aircraft and dividends on unvested shares. That was up from $155,083 in 2008.

Xerox has seen its revenue stagnate because the recession crimped corporate spending on printers, copiers and the supplies that keep those machines going. The Norwalk, Conn., company announced in January that it would cut another 2,500 employees after 3,000 layoffs in 2009. Each cut amounted to 5 percent of the work force Xerox had at the time.

Burns, who joined Xerox in 1980, made her first big move as CEO in September with a $6.4 billion acquisition of Affiliated Computer Services Inc.

• Autodesk reaches settlement in trademark dispute

SAN RAFAEL, Calif. — Autodesk Inc. has settled a 3-year-old trademark dispute over its DWG, or drawing, file format with the Open Design Alliance, a consortium of software developers and users that promotes open and standard formats for computer-aided design data.

Under the terms of the agreement, the Open Design Alliance will cancel its DWG-based trademark registrations with the U.S. Patent and Trademark Office and stop using DWG and DWG-based trademarks in marketing and branding. And Autodesk will abandon its efforts to cancel the Open Design Alliance’s DWG-based trademark registrations with the Patent Office.

Autodesk, based in San Rafael, makes 2D and 3D design, engineering and entertainment software. The company’s shares were down 5 cents at $31.04 Friday afternoon.

Autodesk said the settlement "focuses on avoiding customer confusion by non-Autodesk products’ use of DWG as a trademark without prior permission from Autodesk."
