SEE OR SEARCH CLASS

362, Illumination,

145+, for combined light and structure there provided for. The line between this class (52) and Class 362 subclass is: Class 362, subclasses 145+ takes structure illuminated by artificial means or merely supporting illuminating means. Class (52) takes building structure including features having functions in addition to merely supporting the illuminating means or forming the enclosure, barrier or other structure illuminated. In interpreting this line the presence of a claim to building structure not including illuminating means is considered conclusive of the fact that such additional function features are present.
