That is not at all how the law works. First, not every jurisdiction is based on precedent (some are based on the napoleonic system). Second, precedent only applies in certain situations. The ruling of the trademark office does not set precedent for a court. The ruling of one court does not set precedent for another court except under certain situations (superior court in the same jurisdiction, sister courts in same circuit, etc).
If you are going to make statements that are amenable to fact-checking, I suggest you learn about the topics first.
