The MPEP states: “The U.S. Patent Classification System (USPC) includes subclasses that have been harmonized with subclasses from the European Patent Office (EPO) and the…
Read MoreHow do guidance headings help in patent classification?
Guidance headings play a crucial role in patent classification by providing structure and organization to the Cooperative Patent Classification (CPC) schemes. As outlined in MPEP 905.01(a)(4), these headings serve several purposes: They indicate common subject matter for large parts of a subclass Act as titles for groups of main groups without specific symbols Describe shared…
