patent marking
patent marking. The incorporation or affixation of a patent number to a patented article’s surface or surrounding packaging. • Affixing the patent number to a product gives constructive notice of patent rights to infringers. Without the number in place, a patentee cannot recover losses that occur before the infringer has actual notice of the patent. See PATENT NUMBER. [Cases: Patents 222. C.J.S. Patents §§ 394–395.]
