In many, if not most, instances, the answer is no, it will not be protected. As noted in "How Trade Secrets Can Dictate Winning or Losing a NY Non-Compete Case," there are some types of protected information. HOWEVER, before a New York court will step in and enjoin a former employee from using that information, the plaintiff (and former employer) must, as a general rule, demonstrate that this type of information is not readily available to the public, that the plaintiff spent considerable time and/or money developing this information, and that they tried to keep it confidential.
