Methods to Protect Trade Secrets


Because trade secrets do not involve filing any documents with any governmental agency, there are no time requirements to create trade secret rights. Further, trade secret rights can exist indefinitely, as long as the information is kept secret. However, there is timing involved in the procedures which should be in place to ensure secrecy. First, among these are employee entrance and exit interviews, followed by obtaining signed confidentiality agreements from third parties prior to disclosure of sensitive information.

Creating and preserving trade secrets requires no legal fees. The only costs involved are the costs for the security steps required to keep the information secret. However, businesses must remain vigilant that the minimal legal requirements for obtaining trade secret rights do not result in minimal security measures safeguarding the information. 

Much more significant are the legal fees that companies expend to enforce trade secret rights once the secret has been misappropriated. In most trade secret disputes we have been involved in, the misappropriation seems to occur more due to poor communication and lax security measures than due to malicious intent. The key is to make sure the importance of maintaining confidentiality is stressed to all the individuals who come to know the secret information.

Reasonable Measures

Below are reasonable measures required to protect your Trade Secrets- depending on how your business operates:

  • Lock doors

  • Use good passwords

  • Placing appropriate confidentiality blocks on documents

  • Clean desk policies

  • Employee badge policies

  • Employment agreements

  • Confidentiality or non-disclosure agreements with third parties

  • Lock premises and restrict access via key, identity card, or password/passcode.

  • Limit company information on ID cards.

  • Lock windows that are easily accessible from the outside.

  • Put fax machines and copiers in appropriate areas.

  • Teach employees to shred all unnecessary copies of confidential information.

  • Restrict access to filing cabinets.

  • Clean whiteboards after each use.

  • Notify the recipient of trade secrets, preferably in writing, that the information is proprietary and that the information is not to be disclosed or used by the recipient for the recipient's benefit or the benefit of others without the express consent of the trade secret owner.

  • Enter confidentiality and non-disclosure agreements with employees and third-parties.

  • Establish and maintain written confidentiality policies to be distributed to all employees.

  • Establish and maintain oversight policies and procedures to prevent the inadvertent disclosure of trade secrets in written publications, seminars, speaking engagements, or at trade shows, by employees.

  • Maintain access to trade secrets on a "need-to know" basis only.

  • Establish secretly coded ingredients or data.

  • Separate departments of the Company.

  • Separate components of a trade secret between or among departments and/or company personnel so that each has only "a piece of the puzzle."

  • Keep drawers or areas for secret documents and drawings separated and locked.

  • Stamp documents and drawings "CONFIDENTIAL" or "PROPRIETARY."

  • Enter vendor secrecy agreements.

  • Establish physical barriers to prevent unauthorized viewing of proprietary process technology.

  • Establish and maintain rules and regulations requiring employees to stay in controlled areas about their work stations.

  • Require employees to wear identification badges or carry identification cards.

  • Require sign out/sign in procedures for access to and return of sensitive materials.

  • Reproduce only a limited number of sensitive documents and maintain procedures for collecting all copies after use.

  • Require authorized codes or passwords for access to copying machines and computers. Use key and encrypted computer data access to control theft of secret computer-stored information.

  • Establish and maintain policies and procedures for destruction of documents (shredders).

  • Establish and maintain a policy and practice for advising company employees, on a regular basis, regarding the Company's trade secrets and confidential business information.
