Classification Order 1878 - Class 16, Misc. Hardware and Class 52, Buildings
The USPTO has issued a new classification order, #1878, covering changes to Classes 16, Miscellaneous Hardware, and 52, Static Structures (Buildings). Static structures include all types of constructions ranging from amusement park rides and sports stadiums to wind turbines and gravestones. The principal changes in Class 52 affect subclasses related to beams, columns, girders, shafts, reinforcing bars and rods. As of July 1, there are approximately 92,500 patents and 10,600 published applications classified in Class 52.
I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
