  • Explain the steps that businesses can take in order to protect trade secrets.
  • Describe how trade secrets can be accessed through passive and active disclosure.

The second element necessary to gain trade secret protection is evidence that the trade secret’s owner made a reasonable effort to maintain secrecy. This flexible standard set out by the UTSA is often a point of contention, which results in litigation. To determine whether a piece of information rises to the level of a trade secret, courts often engage in a highly factual inquiry into the security measures taken by the owner to protect a trade secret. For as the Supreme Court has noted, if an owner has not taken steps to protect the trade secret, their proprietary interests may be diminished.xi

Under Company Lock and Key

Because the UTSA may be varied by any state, the level of secrecy required varies from state to state. For example, a version of the UTSA adopted by some states contains a provision that reduces the burden of secrecy placed on the owner of a trade secret. Specifically, this version of the UTSA provides that the existence of a trade secret is not negated merely because an employee or other person has acquired the trade secret without express or specific notice that it is a trade secret if, under all the circumstances, the employee or other person knows or has reason to know that the owner intends or expects the secrecy of the type of information comprising the trade secret to be maintained. Although this provision tips the scales in favor of trade secret protection, it should not be viewed as removing the affirmative obligation the UTSA places on one seeking protection of trade secrets. In both states that have and have not modified the UTSA in this manner, the measures taken to secure the information are key to finding whether the information will be protected as a trade secret.

Because trade secret protection is only given to information that is subject to reasonable efforts to maintain secrecy, every person or company that desires to protect its trade secrets under the UTSA should adopt and implement a trade secret protection plan. The specific elements of such a plan will vary depending on the nature of the intellectual property to be protected, as well as the circumstances surrounding its development and use. However, in taking reasonable efforts to protect the secrecy of the information, many different factors are considered. Because no rigid formula exists to determine if reasonable efforts to maintain secrecy are in place, courts look to many of the best practices, discussed below, to determine whether an owner of information made reasonable efforts to protect its secrecy.

Protection Plans

Memorializing a trade secret protection plan in writing helps to ensure that the business or person is indeed taking reasonable measures to protect the trade secret. The person or company seeking to protect its intellectual property through the use of trade secret law should maintain a written statement of its trade secret security policy. This statement can be written in the form of a policy manual and helps prevent situations in which “unwritten rules” are followed or rules are enforced in a lax manner and then eventually ignored. Moreover, should litigation become necessary, it is easier to persuade a court that the security procedures were indeed a primary concern if they are enumerated in writing. However, if security measures are merely written, but not followed, it may be difficult to prove reasonable efforts to maintain secrecy.xii

A trade secret protection plan should include a program for ensuring that employees are made aware of the trade secret status of information and that the employees are periodically reminded of their confidentiality obligations. Discussions between the employer and the employee may be appropriate. Writing an annual conflict of interest letter to remind management-level employees of their responsibilities in keeping information confidential may also suffice. An essential part of this program is making certain that employees are aware of and familiar with the written trade secret protection plan discussed above.

Employees should also be required to sign confidentiality agreements acknowledging that they have access to trade secret information, that they will not disclose or misappropriate that information, and that they will report all disclosures. Finally, “exit interviews” should be conducted for employees leaving the company. This interview provides an opportunity to remind employees of their written obligation not to disclose or misuse any trade secret information, and to extend an open door to discuss any issues or concerns that may arise in connection with their future employment.xiii

In addition to educating employees, reasonable efforts to protect information often include physically restricting access to trade secrets. Trade secret information should be treated differently from nonproprietary information and should, if possible, be physically segregated so that it is not readily accessible. For example, it is not uncommon to restrict visitor access to sales and administrative headquarters. In addition, access to the intellectual property should be restricted to those with a need to know or access the information. Depending on the nature of the intellectual property to be protected, reasonably restricting access to trade secrets may be as simple as segregating the information in separate file drawers, or may require measures as extreme as designating an entirely separate facility to house the intellectual property.xiv

If possible under the circumstances, physical security measures should be instituted, including the use of locks on doors, gates, and cabinets containing trade secrets. These physical security steps should be obvious to both employees and third parties who may have occasion to visit the area in which trade secrets are stored.xv These types of security measures communicate that an effort is being made to protect the information.

Strategies for Protecting Trade Secrets

Given the ease with which documents can be reproduced, trade secrets that are reduced to writing should be treated with special care. Documents containing trade secrets should be clearly labeled with shorthand instructions that are consistent with the written trade secret protection plan. For example, documents may be marked “secret” or “confidential.”xvi Access to these documents should be monitored and all persons allowed access to the documents should be informed of the meaning of the trade secret designation on the document and the relevant provisions of the written trade secret protection plan. This attention to detail should also be followed in arranging for proper destruction of the documents.xvii

Like trade secrets that are reduced to writing, trade secrets stored on a computer system are particularly susceptible to theft. Access to a computer system containing trade secrets should be restricted in accordance with the written trade secret protection plan and all physical computer- related items such as discs and printouts should contain the same trade secret legend used to identify documents containing intellectual property.

When allowing third parties, be they members of the public or business associates, access to a facility in which trade secrets are stored or used, care must be taken to ensure that trade secrets are not inadvertently disclosed. Disclosure can occur either passively or actively. Passive disclosure might occur by carelessly leaving documents containing trade secrets in open view when business associates from another company visit your facility. Active disclosure might occur during a guided tour of the facility when a tour guide reveals the nature of a project or process the company is working on or has recently perfected.xviii

The type of active trade secret disclosure that can occur outside of the facility where trade secrets are housed is through the dissemination of confidential information at trade shows, in magazine articles, in publications, in press releases, or during public speeches. Such disclosures often occur unwittingly because they are made by marketing executives or mid-level managers who are not themselves instrumental in the development of the trade secret and who are often charged with a goal somewhat at odds with maintaining the secrecy of intellectual property—that is, their duty often is to publicly disclose the company’s achievements. Similar difficulties might arise when engineers or those responsible for the creation of trade secrets exchange ideas with their colleagues from other companies at professional seminars.xix One method of curtailing such disclosures is to insist that all publications, articles, and speeches be reviewed and approved by a “filter” committee prior to dissemination.xx

Although the very nature of many businesses requires that a company disclose its trade secrets to prospective buyers, licensees, joint venturers, or other outsiders, this does not mean that a company must surrender all rights to its trade secrets. Rather, when the company enters into a transaction with a third party, it should cautiously monitor the flow of information to the third party and document the nature of the trade secrets exposed and the specific limited use to which they may be put.xxi You might consider putting outsiders on notice regarding the need to keep information confidential, and even require the signing of confidentiality agreements. The standard of what constitutes reasonable efforts to maintain secrecy varies substantially depending upon the circumstances and the information that is being protected. However, the different methods of maintaining secrecy discussed above all often help to show that the information in question qualifies as a trade secret, and deserves trade secret protection.
