On September 16, 2010 WIPO launched the “IPC Green Inventory,” a new reference page dedicated to highlighting environmentally sound technologies within the IPC Classification. WIPO had this to say:

The tool, “IPC Green Inventory”, contains some 200 topics that are directly relevant to ESTs. Each topic is linked with the most relevant IPC symbols, chosen by experts from around the world.

Join us as we have a look at the site and explore its uses.

The IPC Green Inventory page is cleanly laid out, featuring a table with three columns of information. The left-hand column delineates the topics by name and hierarchical structure, which can be expanded or contracted.

The tree can be expanded or contracted.

This navigation style makes it easy to drill down into specific areas of interest. Unfortunately, this also hides information from the user at the outset, preventing text from being searchable. For example, users who make use of their in-browser search function and are quickly looking to identify biodiesel would only be able to find the related IPC classes by navigating through Bio-fuels and subsequently Liquid fuels.

Alongside the named topics related to the Environmentally Sound Technologies (as defined by the United Nations Framework Convention on Climate Change (UNFCCC)) are columns of information with links to multiple related IPC classification definitions through the WIPO site as well as links to launch automated class searches within WIPO Patentscope. These links are nice shortcuts for users who want to see the hierarchical definitions of the IPC classes in a larger context or start seeing examples of the patent documents related to the technologies.

Overall, the IPC Green Inventory is a helpful resource for searchers or the general public interested in Environmentally Sound Technologies. The site can point people in the right direction to related IPC classifications as well as launch a broad classification search that can serve as the first step in gaining new knowledge in the art. Those looking to take classification searching a step farther can visit our two part series on classification searching:

  5. I do agree with all the concepts you’ve introduced in your post. They’re very
    convincing and can certainly work. Still, the posts are too quick for novices.
