No. The standard is special knowledge of the company's product and its application, or an advanced level of knowledge of its processes and procedures. Proprietary but unpatented methods, internal quality systems and company-specific tooling can qualify if the evidence shows they are genuinely the company's own.
Locate the knowledge in the company, then in the person
Specialized knowledge is defined by reference to the petitioning organization, so the first question is what this company does differently from the trade at large. A documented fixture-programming library, a heat-treat sequence tuned to a particular alloy or an inspection protocol built for a specific customer's parts are all candidates, provided they are written down somewhere and were developed inside the group. The second question is whether this employee holds that knowledge at a level beyond colleagues, shown by their role in creating, refining or teaching it.
A long service record helps only if it links to the knowledge itself. Where the honest answer is that the employee is excellent but interchangeable with other skilled machinists, L-1B is the wrong tool, and the review should say so before the employer invests in a petition.
