The distinctiveness of a trademark means that the trademark you are preparing to apply for has no obvious features compared with the words in real life, such as "car brand car"
"cream brand cake"
"table brand chair"
and so on. Even if you approve your trademark, you can't contact your trademark directly when you see your goods.
1. the ability to distinguish each other. In the statistical hypothesis test, the probability value of recognized small probability events is called the significance level of statistical hypothesis test. The same quantity is measured for many times, and then the average value is calculated. For the positive and negative difference from the average, it is its uncertainty. The greater the difference, the greater the uncertainty of measurement. For a random variable with a specific probability of occurrence, its specific value interval-a certain numerical range ("an interval").
2. Specifically, a trademark has the attribute of indicating the origin of an enterprise's goods or services and distinguishing them from those of other enterprises. Is one of the essential elements of a trademark.
3. difference
Significance level refers to a probability value
uncertainty is the probability interval of an event
confidence interval is an effective interval artificially taken with reference to actual users
4. significance was first put forward by Fisher in hypothesis testing. There are two kinds of errors in hypothesis testing: rejecting truth and accepting falsehood. Significance testing only considers the occurrence of rejecting truth errors. That is to say, considering the Significance of the original hypothesis, the probability of rejection is controlled below the threshold alpha given in advance to consider whether the original hypothesis is correct. Simply put, it is to judge whether the statistical quantity to be tested is significantly different from the hypothesis < P > If the difference is obvious, the demarcation probability is the significance probability.
