Before you spend on a filing, USPTO.gov is the place to check whether your mark or invention is in scope. It is the federal source for trademark and patent information in the United States, with public search tools, filing paths, fee references, and status records. For trademark work, it helps users review existing marks, compare goods and services, and read the filing rules before choosing a class or specimen. For patent work, it supports prior-art searching, application tracking, and access to agency guidance.
Judge it by fit: whether the issue sits inside USPTO jurisdiction, whether the public record is clear enough for self-service searching, and whether the filing needs technical drafting or attorney review. It is most useful for authoritative forms, records, and procedural guidance. It is less useful when ownership, likelihood-of-confusion, claim scope, or prosecution strategy depends on specialized judgment beyond a web form.
