Finally having a chance to go through the Contact Us mail-box and was sent a tip about the site FreePatentsOnline.com. The site allows you to a highly customizable search for patents and chemicals patents (requires you to have a free account.) You can download the documents in PDF format. Search options include: US Patents Patent Applications European Parliament (EP) documents World Intellectual Property Organization (WIPO)/ Patent Cooperation Treaty (PCT) Abstracts of Japan The only other Patent Search I’ve used before was the Google Patent Search (Beta).
