South Korea’s decision to hit Intel with a £13 million antitrust fine is the latest example in a series of antitrust cases that have dogged the world's largest chip maker for years.

Here is a rundown of Intel's brushes with antitrust investigators and lawsuits around the world since 1990:

1990

Dec. 19: Microprocessor maker Cyrix filed an antitrust lawsuit against Intel in the U.S. District Court of the Northern District of Texas. "Intel has engaged in a campaign of unlawful exclusionary practices to protect its coprocessor monopoly from competition by Cyrix," the company said in a statement.

1991

June 29: The U.S. Federal Trade Commission (FTC) informed Intel that it was investigating the company's business practices.

Aug. 20: Advanced Micro Devices brought a US$2 billion antitrust lawsuit against Intel in the U.S. District Court of the Northern District of California, alleging that Intel "engaged in unlawful acts designed to secure and maintain a monopoly."

Dec. 19: U.S. District Court Judge James Ware dismissed part of AMD's antitrust lawsuit against Intel because a four-year statute of limitations had passed for some actions listed in AMD's complaint. AMD declared its intention to press forward with the lawsuit anyway.

1992

May 28: Processor maker Chips and Technologies sued Intel for antitrust violations in the U.S. District Court of the Northern District of California. The claims were a response to a Feb. 1992 patent lawsuit filed by Intel.

1993

Feb. 4: Chips and Technologies agreed to dismiss its 1992 antitrust claims against Intel as part of a settlement to resolve a patent dispute between the two companies.

July 15: The FTC completed its investigation into Intel's business practices, saying no evidence was found to support charges of anticompetitive behavior.

1994

Feb. 4: Cyrix dismissed its 1990 antitrust claims against Intel as part of a patent-dispute settlement between the two companies.

1995

Jan. 11: AMD and Intel announced a broad legal settlement that ended several court cases between the two companies, including the 1991 antitrust lawsuit filed by AMD.

1997

Aug. 27: The FTC requested additional information from Intel concerning its plans to acquire Chips and Technologies, citing antitrust laws. At the time, Chips and Technologies was a major supplier of graphics chips.

Sept. 25: The FTC began a second antitrust investigation into Intel's business practices. This investigation was conducted separately from the review of Intel's offer to acquire Chips and Technologies.
