No. The actual knowledge standard does not require uniqueness or proprietary secrecy.
Explain the individual expertise
Identify what the employee can apply or understand beyond simply having access. A public document alone neither establishes nor disproves the complete claim.
The classification reaches knowledge that is special — of the petitioner's product, service, research, equipment, techniques, management or other interests and their application in international markets — or advanced, meaning an advanced level of knowledge or expertise in the organization's processes and procedures. Knowledge of a regeneration sequence developed inside the company, recorded in its own schedules and refined against its own field results, can support this category, but qualifying knowledge need not be proprietary or unique. A qualifying relationship, one continuous year of qualifying employment abroad in the previous three years, and a U.S. role requiring specialized knowledge of the company's own product, process or procedure. Explain the particular internal system, technique, product architecture, service model, or process at issue; state how the employee acquired it; and show what U.S. work depends on it. Answers that point at a specific artefact, such as an internal configuration, a proprietary routine or a method documented only inside the organisation, describe knowledge the classification can reach. Specialized knowledge concerns company products, processes, or procedures rather than general skill; a new office starts with one-year approval, while the classification ordinarily ends after five total years.
