MISCELLANEOUS

SEARCH NOTES FOR CLASS D25.

(1) For arcuate dome, see subclass 19.

(2) Includes structures that enclose a person.

(3) Search subclasses 56+ for roof, per se.

(4) Includes element.

(5) For elevator, see D34-33.

(6) For handrail or post, see respectively, subclasses 119 and 126+.

(7) Includes element.

(8) Includes shutter; includes a combination with surround. For surround per se, see subclass 60.

(9) Includes only screens or guards that are designed solely for window or door. For grille adaptable to other architectural uses, see subclasses 152+. For perforated sheet material, see D5-1+.

(10) Includes rigid drapery cornice.

(11) If structure has wall, see subclasses 1+.

(12) Includes stage set.

(13) Includes arch structure.

(14) Includes cantilever support.

(15) For mobile stairs, see D34-30.

(16) For component that is adaptable to other article, such as handrail, post, etc., see subclasses 102+.

(17) Planar surface not considered.

(18) Planar surface not considered.

(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.

(21) Opening must extend through the article.

(22) To be classified in this subclass, article must have uninterrupted extruded shape. If openings, protrusions, rivets, vertical striations, etc., are disclosed with an elongated article, patent is classified in subclasses 126, 136 or 164. For articles with specific end configuration such as fence picket, see subclasses 126+.

(23) If molding has extruded shape, see subclasses 119+. For corner or end piece, see subclass 102.

(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+.

(27) Opening must extend through the article. Otherwise patent is classified in subclasses which follow.

(28) Exclusive of random acoustic texture within symmetrical pattern unit, or of tongue or groove edge detail.

(29) Includes railing, edging, etc. However, if railing, etc. has an extruded shape, patent is classified in subclasses 119+. For corner or end piece, see subclass 102.
