As answered by people managing Eloquent JavaScript and TMScope.
TMScope's answer:
TMScope goes beyond exact-match searching. It screens against 12 million U.S. federal trademark records to find conflict signals that most free tools miss. You get a comprehensive risk assessment and plain-English report in minutes, not days. The methodology was built with the approval of an intellectual property attorney.
TMScope's answer:
TMScope is faster and more affordable than an attorney search, and more thorough than free tools. It catches conflicts that exact-match searches miss. Results come in minutes with a structured report you can act on, not raw data you have to interpret yourself.
TMScope's answer:
Founders, entrepreneurs, and small business owners who are choosing a name for a product, company, or brand and want to check for trademark conflicts before committing to branding, domains, or legal fees.
TMScope's answer:
I'm a physician-technologist. I take care of patients during the day and build software at night. While working on a new product, I needed to check whether my name was safe to use. The free tools only caught exact matches. Attorney searches cost $500+ and took a week. There was no practical middle step. So I built one.
TMScope's answer:
Next.js, TypeScript, PostgreSQL, Tailwind CSS

Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
