Actual industry terminology is critical<\/strong><\/p>\n\n\n\n<p>Even if a mark appears descriptive in theory, it will not be refused unless it is <strong>actually used in practice<\/strong> to describe goods.<\/p>\n\n\n\n<p><strong>2. Alternative expressions matter<\/strong><\/p>\n\n\n\n<p>If different terms are commonly used in the industry (e.g., \u201cflat roof\u201d), the applied-for mark may be considered distinctive.<\/p>\n\n\n\n<p><strong>3.
