Intel Slowing demand and challenges to dominance

After 2000, growth in demand for high-end microprocessors slowed. Competitors, notably AMD (Intel's largest competitor in its primary x86 architecture market), garnered significant market share, initially in low-end and mid-range processors but ultimately across the product range, and Intel's dominant position in its core market was greatly reduced.[17] In the early 2000s then-CEO Craig Barrett attempted to diversify the company's business beyond semiconductors, but few of these activities were ultimately successful.

Intel had also for a number of years been embroiled in litigation. US law did not initially recognize intellectual property rights related to microprocessor topology (circuit layouts), until the Semiconductor Chip Protection Act of 1984, a law sought by Intel and the Semiconductor Industry Association (SIA).[18] During the late 1980s and 1990s (after this law was passed) Intel also sued companies that tried to develop competitor chips to the 80386 CPU.[19] The lawsuits were noted to significantly burden the competition with legal bills, even if Intel lost the suits.[19] Antitrust allegations that had been simmering since the early 1990s and already been the cause of one lawsuit against Intel in 1991, broke out again as AMD brought further claims against Intel related to unfair competition in 2004, and again in 2005.

In 2005, CEO Paul Otellini reorganized the company to refocus its core processor and chipset business on platforms (enterprise, digital home, digital health, and mobility) which led to the hiring of over 20,000 new employees. In September 2006 due to falling profits, the company announced a restructuring that resulted in layoffs of 10,500 employees or about 10 percent of its workforce by July 2006.
