Trademark Search and Clearance Before Filing
A pre-filing trademark search and clearance is necessary because the rules of refusal and nullity are written precisely in the law: Article 5 of the Law on Trademarks enumerates the relative grounds on which a mark will not be registered; Article 11 determines who is "earlier" and how priority is counted; and Article 28 establishes the nullity rules — that is, what a mistake after registration costs the applicant. A properly planned clearance is drafted from the text of exactly these three articles: the search brief is written by the law, not by intuition.
