A more thorough explanation:

Definition: A case lawyer is an attorney who specializes in a specific field of law and has extensive knowledge of legal cases related to that field. They may not have a broad understanding of other areas of law.

For example, a lawyer who only handles cases related to personal injury law would be considered a case lawyer. They would have in-depth knowledge of personal injury cases and the laws surrounding them, but may not be as knowledgeable in other areas of law such as criminal or family law.

Another example of a case lawyer would be a patent lawyer who specializes in intellectual property law. They would have a deep understanding of patent cases and the laws related to them, but may not be as well-versed in other areas of law.

Overall, a case lawyer is an attorney who has focused their practice on a specific area of law and has extensive knowledge of legal cases related to that field.
