DefinitionThis class provides for (1) highway, pathway or walkway structure, per se, including the form or arrangement of such structure for vehicular or foot traffic; (2) processes for making, installing, repairing or maintaining such structure; and (3) apparatus for installing, making, repairing or maintaining such structure where such structure, apparatus or process is not otherwise classifiable as either (a) specifically provided for in other loci or (b) of such general utility as to be provided for elsewhere on the basis of such general utility. (See Subclass References to the Current Class, below, for known collections of such nature and the particular lines of demarcation.) (1) Note. Claims not controlling in Patents prior to 1930. Patents prior to 1930 have not necessarily been classified by claims so that the placement of these old patents does not necessarily indicate lines of classification. Many of such old patents have been classified in accordance with their total disclosure. Most of the patents, however, regardless of their age have been assigned in accordance with their claimed subject matter. (2) Note. This class (404) does not provide for materials or compositions, per se, used in the construction, maintenance or repair of roads. The identification of a specific road component, otherwise solely set forth in terms of its constituent materials, without significant structural description of said component is still not enough to effect classification in this class. See the search note, below, under Subclass References to the Current Class, for the specific loci for such materials and compositions. |
