A grower who developed the company's own climate-control thresholds, its substrate recipe and the sequence it uses to move plugs from germination to finishing holds knowledge that exists only inside the company. Specialized knowledge does not require that the knowledge be unique, proprietary, or unavailable anywhere else; it requires either special knowledge of the employer's products, services or their application, or an advanced level of knowledge of the employer's processes and procedures. The principal’s L-1B case must stand on the employee’s own special or advanced company knowledge, an uninterrupted qualifying foreign year in the relevant three-year window, and active related entities.
