2. Why Do US Patents & Trademarks Matter?

3. 3. Enter Search Terms: Use patent numbers, inventors’ names, or keywords (e.g., “artificial intelligence algorithms”).
4. 4. Refine Results: Filter by date, type (utility/design), or status (granted/pending).

3.2 US Trademark Lookup Process

• • Trademark Electronic Search System (TESS): USPTO’s free tool for trademark searches.
