The following are a collection of posts on trade secrets. Trade secrets are essentially of two kinds. On the one hand, trade secrets may concern inventions or manufacturing processes that do not meet the patentability criteria and therefore can only be protected as trade secrets. This would be the case of customers lists or manufacturing processes that are not sufficiently inventive to be granted a patent (though they may qualify for protection as a utility model). On the other hand, trade secrets may concern inventions that would fulfill the patentability criteria and could therefore be protected by patents. In the latter case, the SME will face a choice: to patent the invention or to keep it as a trade secret.
