See this summary by Prof. Nancy Kim, who says in part:
Under the law, effective July 1, a “technology business” is defined as a “trade or business that derive the majority of its gross income from the sale or license of products or services resulting from its software development or information technology development, or both.”
It excludes businesses that are part of the broadcast industry or any telecommunications carrier.
There are exceptions, such as when the restrictive covenant is in connection with the sale of a business or partnership.
Furthermore, agreements to protect trade secrets are still valid.
