What follows are the subclasses from one class of the Manual of Classification for US patents. As you scroll through the list and encounter a class/subclass of interest, you can jump back to the top and retrieve patent titles by entering the class/subclass in the box below.
Enter a class/subclass code here to get a list of patent titles. Use
any of the following forms:
363-131 121-55A 14-.5
that is, no embedded spaces, class and subclass seperated by a dash, and any
subclass letters capitalized. Currently Design Patent titles (those in the
classes of the form Dxx.yy) are not retreivable.
