IPONZ Linker per Louis Habberfield-Short

Clicking the extension icon while using the search interface of the patent, design, or trade mark registers of the Intellectual Property Office of New Zealand (IPONZ) will extract all current search parameters and generate a link.

This works on individual records, and on the search page with any combination of text/date-based fields, dropdowns, checkboxes, and radio buttons. Following the link will run the search unless you don't have the extension installed, in which case you'll land on a page directing you to install it.
