PTO Manual of Classification for US patents

PTO Manual of Classification for US patents

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.
