(19) If repeat protocol is apparent from the disclosure, patent is classified under earlier subclasses. If, however, the disclosured pattern element does not indicate how it can repeat, patent is classified here.
(20) For edging, see subclass 164.

(24) For generic elongated stock material having indefinite length, see subclass 164.
(25) For embossed panelwork or for grill, see subclasses 138, 152 or 157.
(26) For brick per se, see subclasses 113+.
