How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.
Registration of a mark on the principal register provided by this chapter or under the Act of March 3, 1881, or the Act of February 20, 1905, shall be constructive notice of the registrant's claim of ownership thereof.
