CCP 2019.210 provides that in a trade secret  misappropriation case under Civ. Code 3426, before commencing discovery relating to the trade secret, the party alleging the misappropriation shall identify the trade secret with reasonable particularity.  This decision holds that the plaintiff cannot wait to raise a new alleged trade secret in opposition to a summary judgment motion directed towards its previously disclosed trade secrets.  If it learns through discovery that defendant stole another trade secret, it must file a formal motion to amend its 2019.210 disclosure and to continue any summary judgment motion proceedings until discovery on that new claim can be conducted.  Here, the plaintiff merely mentioned the possibility of designating a new trade secret in a single sentence on page 18 of its summary judgment opposition, which was inadequate to properly raise the issue as well as too late.
