Patents are an important information resource in the engineering design process both in legal terms and to see how others have tried to solve a problem. The resources listed are not a comprehensive list. This page is not meant to replace consulting a patent lawyer.


Patent Drawing of a Card Catalog Drawer

Long before online library catalogs, libraries kept index cards for each item in their collection. These cards were filed in drawers such as this that were then kept in cabinets for patrons and librarians to use.

Unfortunately, due to the volume of the image data, available funding, and other technical considerations, USPTO cannot convert these images to a format more popular on the Web either permanently or by converting on-the-fly as they are delivered.

  • Cooperative Patent Classification
    The Cooperative Patent Classification (CPC) effort is a joint partnership between the USPTO and the EPO where the Offices have agreed to harmonize their existing classification systems (ECLA and USPC, respectively) and migrate towards a common classification scheme. This is a strategic decision by both offices and is seen as an important step towards advancing harmonization efforts currently being undertaken through the IP5’s Common Hybrid Classification (CHC) project. The migration to CPC will be developed based in large part on the existing European Classification System (ECLA) and will be modified to ensure compliance with the International Patent Classification system (IPC) standards administered by the World Intellectual Property Organization (WIPO).
    The PATENTSCOPE database provides access to international Patent Cooperation Treaty applications in full text format on the day of publication. The information may be searched by entering keywords, names of applicants, international patent classification and many other search criteria in multiple languages.
