Well-protected know-how and trade secrets can be powerful weapons that, notably, do not expire. That’s an advantage over patents, for instance. When applying for a patent, you have to accept that all details relating to the invention will be disclosed to the public. In addition, legal protection stops completely, once the term has ended.
Such limitations do not apply to know-how and trade secrets. However, that comes at the price of vulnerability: Once sensitive knowledge ends up outside company walls, there may be few or no remedies. Therefore, prevention is better than cure. With the right protective measures and clear arrangements, know-how and trade secrets can often be kept safe.
